<Purchased WORKTOY in Japan, Tech YouTuber TAKA's honest review video>








WORKTOY® brand has been ambitiously prepared by Smith S3 since 2014,and began as the project name for developing a Korean-style high-end chair.
JOYFUL WORKLIFE.
WhyWORKTOY? The moment you encounter this chair,
'Work' is now'Toy' as if together with
you will always find joy.
WORKTOY® is an authentic Korean chair brand with over 10 years of development history. It is fundamentally different from office chair brands that have simply followed trends.















A collection of delicate parts is used to create it,
Relentless testing brings it to completion.

The WORKTOY® brand, for the launch of its chair,
has conducted testing for over 10 years..
Just like a newly released car, a newly launched chair must undergo testing
for more than a year,as it is a product that must be developed with extreme delicacy and precision.
Most manufacturers switch directly to consumer sales once the product is completed.
However, Workless is different. WORKTOY® hassold over 10,000 chairs since 2014,
and has continued to upgrade and test them for more than 10 years,
and the CT 1.0 (first generation model) has already been recognized to the extent that it is sought after by many well-known companies such as the major corporations S and L,
and has been consistently chosen by numerous famous enterprises. It is a chair that has already been acknowledged.
CT 3.5
This time, WORKTOY®3.5th generation It is.

Why Worktoy CT3.5?
"A high-end chair should feel different when you sit on it."
For the past several years, we have focused on a single goal.
"To set a new standard for chairs."
That's why Worktoy
did not want to make a chair that only looks stylish or only has impressive specs.
We trulywanted to create a chair that makes you feel 'different the moment you sit down'.
The first answer was WORKTOY CT 3.0,
and today,the upgraded version,CT 3.5
is being unveiled to our supporters for the first time.
"Where did the 2nd generation go?"
We share the real development story of Worktoy.
"3rd generation? But where did the 2nd generation go?"
That's a good question.
In fact, WorktoyCT 2.0 (2nd generation) model
was being developed for about two years between 2020 and 2021 for actual market release.
Numerous feature improvements and material experiments,
and even review tests at various exhibitions... It went through hundreds of reviews and tests.
But as a result,
compared to the existing CT 1.0,"Is this really a satisfying evolution?"
We couldn't nod in agreement to ourselves.
So,in 2021, the market release of CT 2.0 was abruptly halted and,
a year later, the fully improved WORKTOY CT 3.0 was finally released.
That is,
the CT 3.0 that was first unveiled through Wadiz funding in 2023 was it.
The hidden high-end chair.
A genuine product known only to those in the know.
So, what’s different about the CT 3.5?
CT 3.5Maintains the functional structure and durability of the previous CT 3.0 while
officially launching the 'Project' line at a reasonable price point and
reflecting actual feedback from our supportersby adding a fabric headrest option to
create a renewed version with detailed improvements in seating comfort, usability, and hygiene management.
💬 In short, what is CT 3.5?
CT 3.0’s durability and design remain intact
A chair improved with a focus on seating comfort and user experience
High-end as always, with even more refined details.
CT 3.5 is not just a simple renewal
but a continuous evolution for the user.

CT 3.5 is recommended for these people.
- Office workers/remote workers who sit all day
- Those looking for a comfortable premium chair even in summer
- Those searching for a life-changing chair that is truly comfortable for the neck and back
- Those who want to maintain support and hygiene even after long use
- Those who want to change not just a simple chair, but the entire sitting experience
To reward your patience with outstanding specs
From the chairUnprecedented specs and benefits have returned.


Only on WadizYou can get it in the 400,000 KRW range.




This price will increaseafter the pre-order ends.
This chair has the maximum options a chair can have. It refuses to be compared with existing cheap chairs. CT 3.5 isThe efficiency of important tasks in a chair andThe ultimate comfort for relaxation in a chair has been maximized.
The CT 3.0 and 3.5 versions have the same chair functions.
Chair, nowChoose carefully and thoroughly.
The chair is responsible for your work-life.
It is equipment like a computer that you use for work.
You spend more time in contact with it than your bed, it is closest to your body, and it protects your body the most.
Therefore,Now you need to be even more meticulous than when choosing a bed.




A chairfocus andrest must be able to provide both of these.
Concentration in a chair is created by the rest you get on it.
Because of this relationship,only when you rest properly can you achieve high concentration.
Among these, rest is provided by the chair's headrest.
So,the headrest is an important part that determines the quality of rest,
and it must provide pure comfort without any discomfort.





If you apply the concept of pillow making, which we commonly use for beds,
incorrectly to the headrest,
The more uncomfortable headrest is born. It is.
While a pillow receives vertical force from the weight and gravity of a person lying down,
a headrest transfers force horizontally, not vertically, so.
Therefore, materials like sponge or latex actually feel harder compared to the backrest mesh so,
you get a firmer feeling. It may seem like the sponge supports your neck well,
but when it touches your neck directly, it can actually bounce off your neck and create discomfort by feeling hard.

Structurally, the human body feels that
the tension of the mesh is less comfortable than the headrest that receives the weight of the head,
so the headrest should be softer to feel comfortable.
After more than two years and dozens of samples tested,
we found that compared to the traditional sponge types,
a headrest filled with cotton is much softer,
providing perfect comfort without any sense of awkwardness in usability, which we could feel.
When you lean back through tilting, your neck, not your head, is directly
We have chosen a structure that can envelop you, allowing you to experience true relaxation.
Cushion firmness you can adjust yourself
People's body weights, neck shapes, and preferred cushion firmness all differ, but chairs have always maintained the same design and cushion firmness. That's why Smith designed the chair for the person sitting in it.With the person at the center of everything,we designed it.
To create a comfortable angle and cushion for the neck,we made it possible to adjust the filling directly.
The structure we developed isthe headrest + neck cushion system.
We made the head cushion cover in a pocket style,so that the filling can be adjusted independently. If you want a firmer cushion, add more filling; if you want a softer cushion, remove some filling.
In this way, the headrest adjusted to fit your neckwraps around your neck to prevent it from shaking.
The neck cushion feels as if you are lying on a cloud, offering a level of comfort never before experienced in a chair,
allowing you to feel soft comfort.
The moment you rest your head on the Worktoy head cushion,As soon as you lean your head,
In just one second, all memories of previous chairsWill instantly disappear. Will be gone.
For even greater satisfaction,Huvis Microfiber Filling
The head cushion filling (fiber) of the Worktoy CT3.5 chair is made with the highest-level 'MICRO' (microfiber) filling from Huvis, Korea's No.1 functional fiber listed company.Among Huvis' fillings, 'MICRO' (microfiber) is considered the highest level. It is a premium ultra-fine filling woven at one-tenth the thickness of ordinary fiber. After applying Huvis' microfiber filling to our headrest cushion and conducting our own tests, we found it to be much softer and have superior cushioning resilience compared to previous fillings.
100% Made in Korea,Patent-certified cover-type head cushion


WORKTOY® CT 3.5The headrest comes in two selectable sizes.


The size above is S, and the one below is L.

Depending on a person's body type and posture,The pressure and position on the neck will vary.
The neck cushion also comes in two sizes, S and L. Simply choose the size that fits you and change the cover—done!
AndThe height of the headrest can be adjusted in as many as 9 steps. You can find a headrest optimized for your neck.
The S size is for those with a relatively smaller build, while the L size is for men with a larger build. The S size is recommended for female users. We recommend it.
However, there is no single answer.
You can choose according to your preference, depending on your sitting posture or the purpose of the chair.
If you want both sizes of head cushions for various uses, you can add just the cushion separately. Pre-orderIt is offered at a special pre-order price, so don't hesitate.




Since the head cushion often comes into contact with your skin, its lifespan is relatively short and it gets dirty easily.
In such cases, since you can't just replace the headrest of the chair, you may consider changing the entire chair.
For this very reason, Workless insisted on a cover type.
This insistencewas proudly recognized by the Korean Intellectual Property Office. (Registered Patent 10-2424490)
Don't change the entire chair,just replace the neck cushion cover.
However,With the CT 3.5, you only need to replace the neck cushion cover.
Without changing the entire chair, simply replacing the cushion cover transforms it into a new headrest.
Thanks to continuous material development, you can now choose between fabric and leather versions.


Natural materials are too soft and lose their shape, while regular synthetic materials are too hard,so Workless developed a material optimized for the neck.
The leather material used for the neck cushion coveris a material independently developed by Smith in collaboration with a renowned domestic fabric manufacturer.
Although it is a highly flexible material, by applying a hidden layered structure, it also maintains its shape
and exudes a sense of luxury.
Since the material comes into direct contact with the neck, we chose a skin-friendly material for both shape retention and safety, so you can use it with confidence.No harmful substances such as formaldehyde were detected.
On both sides of the headwe used a highly breathable punched material so you can feel comfortable at all times while using it. When you press the headrest, you will feel the air escaping from both sides of the punched material.
Nonwoven fabric is added inside to maintain its shape.
Sturdy finish,piping finish for a luxurious touch

To upgrade the neck cushion shape retention and durability of the headrest, we used a piping finish.
Although it is a challenging finishing method for thick leather materials, we adopted it for durability and luxury.
And for even more perfect production,manufacturing is carried out at the headrest manufacturing facility of Company K, an automotive seat manufacturer.


The material of the seat and backrest, which are the parts that come into contact with your body first, determines the quality of the chair.
The third-generation CT 3.5 has been further upgraded in elasticity, durability, and pattern design compared to the mesh used in the first generation.
Guarantees definite breathability and durability.
Uses raw materials from global brands as they are.

WORKTOY® CT 3.5Both the seat and backrest are made of highly breathable mesh material. Produced.
Unlike the typical seat mesh used only for backrests or in low-cost chairs,
Uses the same pattern of Hytril material as high-end brands in the 2 million won range. Manufactured.
(America's Herman**'s Co* Chair)
Hot summer, relieve hip heat?

The mesh of Worktoy is a high-elasticity suspension-type mesh with air holes evenly
applied,providing excellent breathability.
With this amazing high-elasticity mesh material,
nowNo problem even in the hot summer, right?

We compared our actual sponge seat product with the Worktoy mesh seat.
To increase accuracy, we measured the surface temperature after sitting for a short 60 seconds each, right after arriving at the office where the air conditioner was not turned on. It was clear that the typical sponge seat had a higher heat sensation, which causes discomfort when sitting.If the air conditioner or other cooling devices like a fan are on, it is expected that there will be a significant surface temperature difference between the tightly sealed sponge seat and the highly breathable Worktoy mesh seat. It is expected.
To make it easier to compare,
As applied to cars,The difference between a regular seat and a ventilated seat, That is how I would describe it.

Hytel material?

It is a material made by the famous American company DuPont, which is well-known for nylon.
Hytel is famous as a raw material for highly elastic fibers, and it is a premium material used in all high-end mesh chairs.
Woven by a well-known domestic company,
Using premium overseas raw materials,Woven by a mesh-specialized company with advanced technology in Korea, It is being produced.
Recognized as a high-quality mesh in Korea, you will be surprised by the comfortable elasticity when you see and sit on it.
Compared to the first-generation model, the mesh now has a more woven feel, and the tension has greatly improved.



For the lumbar and backrest,Increase the adhesion,
And long-lasting sustainable comfort.
Most office chairs follow trends and have structures that focus on supporting the lumbar area. Unfortunately, many companies stray from ergonomic design and simply imitate the shape, which can actually cause discomfort when sitting for long periods.The discomfort known as 'protrusion' or 'poking'. can also occur. The lumbar support that Workless envisionsis a structure that naturally supports the lower back without any sense of elasticity or discomfort from the chair, while maintaining a high level of adhesion for a long time.


We boldly removed the physical lumbar support that was applied to the first and second generations in the third generation CT 3.5.
After participating in the production of famous overseas brands and selling them directly for over 10 years, we studied the design patterns of high-end chairs and found a way to support the lumbar area more stably without installing a physical lumbar support.
CT 3.5'sHD Lumbar Support™
maximizes the adhesion between the user and the lumbar support.
HDLumbar Support™(hide lumbar support) is ahidden lumbar support that, when viewed from the side, has a backrest shape that supports the lumbar areawith an ergonomic line. Its simple design provides a more luxurious satisfaction, and functionally, when combined with the tension of the mesh,it holds the lumbar area very securely.

The HD Lumber Support™ rotating lever extends in two stages, protruding about 20~30mm. It does.
When switched to the second stage, it provides a higher level of comfort to your lower back by more firmly filling the empty space in the lumbar area.
The strong adhesion evenly supports all parts of the lower back, helping you maintain a comfortable posture. With intensive work,Even after spending long hours together, it will no longer be a strain.


It is rare to find a chair with both functions except for luxury brands.
In most chairs, Between the two, Only onefunction is included, and having bothfunctions in a chair is very rare.
However, the high-end chairWORKTOY®CT 3.5both functionswas designed to let you enjoy both functions.
CT 3.5offers both functions.


The locking function of the CT 3.5's dual tilt allows you to lock the angle you want when tilted back. A function to fix the angle. That's how you can see it.
Since the selected angle is fixed and can be used without movement, you can enjoy comfortable rest and work in an environment tailored to you.



The limited tilt function of the dual tilt allows you to set the maximum tilt angle of the chair, so when you lean back,it only tilts up to that angle,and returns to the original angle without locking,restoring to the originalangle,function. You will realize how convenient this function is once you try it. That is why it is a premium feature usually found only in high-end brand chairs.
You can even adjust the tilt tension strength.


By operating the tilt tension lever,you can set the strength of the backrest tilt..
There is a + and - direction, so you can adjust it to fit your body type or work environment. Find the tension that suits you best.



As remote work and online classes have become more common, people are increasingly using office chairs at home. However, chairs are basically designed for office use, based on the height of a person wearing shoes, so,when used at home, there may be issues.The chairs were often too high.

Especially when you sit with your hips at the edge of the chair, your feet may be lifted off the ground, which ultimately changes your sitting posture and becomes a factor that makes your body uncomfortable.

SoCT 3.5, compared to the previous first and second generation models,has been lowered by a whopping 20MM. It may not seem like a big difference numerically, but the difference your body feels when sitting on the chair is enormous.

If you are over 155CM, whether you are an adult or a child,you can sit comfortably without your legs floating.

Depending on the user's body type,A function that allows quick adjustment with a single lever It can be adjusted back and forth in 5 steps.
(The project model has 4 steps)
For work, we recommend setting the seat as short as possible to reduce the burden on your lower back.
For rest, adjust the seat so that the weight is distributed evenly.
Please adjust it appropriately.

Initial included stage
Why is it so detailed?
We sometimes overlook it, but even the height of the armrests must be perfect to maintain a comfortable posture without strain.By finely adjusting the height of the armrests, you can maintain a stable posture without collapsing,
With five levels of adjustment forward and backward, you can perfectly fit it to your body, even up to your elbows.
It also rotates left and right, creating a guideline for your keyboard or mouse, providing a comfortable working environment.


Each part is made from premium materials.
High-end Worktoy CT3.5 Supreme.
Project vs. Supreme: What are the differences?


The main body and base are made of high-strength aluminum.
Unlike the first and second generations, the main body and oval base of the CT 3.5are made of aluminum, not plastic. This provides significantly higher durability compared to plastic, and not only that,the aluminum is finished with a matte texture color special coating, enhancing both durability and luxury.
The textured coating method creates a rough surface, making it much more resistant to scratches and stains than gloss, and much easier to maintain. The color iscarbon gray, a trendy color overseas, adding a touch of luxury.
Smooth movement, nylon caster wheels.

We use large 65mm nylon caster wheels that are highly durable and offer excellent mobility even after long-term use.
Since this office chair is also used at home, the caster wheels are smoothly curved. At Smith, we provide details for our supporters.
Fabric seat cover. so you can choose according to your preference.
The seat of the CT 3.5 is made of mesh,but we have created a dedicated fabric cover so you can replace it with a fabric cushion that offers excellent comfort. Depending on your environment or preference, it can be easily attached or detached as needed and is also washable.
(It is recommended to use it together with the newly released fabric headrest, which is made of the same color and material.)


People often think that the true face of a chair is its front. However, in reality, what someone sees of a chair is always its back.
We hoped that the WORKTOY® CT 3.5 chair could offer various impressions with its true face,so we applied the CT FACE™ color point system. This is a signature feature unique to the CT 3.5 that no one has ever attempted before.

The easily replaceable CT FACE™ frame can transform a previously dark and rigid mechanical work environment into a joyful and unique space.At times, it can be used as a tool to distinguish departments or teams within a company by color, or it can be a way to express your work status. Unleash your creativity and imagination.
CT FACE™ Frame A variety of colors




Why are chairs always monochrome?Since the production of the first-generation model,we have been inspired by the colors of powerful tool companies, using shades that no other company has used. PassionateFrom golden yellow to trendy heath gray and beyond,you can express yourself with a variety of colors.You will be able to do so. New colors are continuously released through collaborations with various brands, so you can easily replace the frame at any time by simply purchasing it. Now, chairs are fashion. Experience the feeling of always sitting in a new chair.
Try changing and creating it yourself.
We designed it so that users can customize it themselves, not just as a simple chair.You can do it yourself without having to leave it to a professional.IncludedYou can easily change the face frame with the included tools. When you move to a new place, Don't change the chair,Just change the frame. CT Even just changing the FACE™ frameCompletely transforms the atmosphere of your home.

All processes are carried out domestically. If you look closely, it's hard to find a chair where every step is done in Korea. It will be difficult.Of course, because it's expensive And not easy.
WORKTOY® CT 3.5 is made with the best quality possible using domestic technology.
Worktoy, made with luxury craftsmanship in a domestic production line filled with know-how accumulated from handling countless luxury chairs over the past 10 years, is already so renowned that it has been recognized by many large corporations.
Even fast after-sales service
Smith provides fast and accurate service through the Kakao channel. In addition, we have our own offline AS center where you can directly bring in repairs, allowing for quick service and much better quality service made in Korea.



Usually, when you buy a chair And use it,It breaks and you need after-sales service, You end up leaving it for repair, After a certain period of time has passed, after-sales service may become difficult due to the discontinuation of the model. In some cases, it is difficult. Already, more than 10 years ago,companies and customers who purchased the Worktoy CT 1.0 version are still using the upgrade service for parts with the CT 3.5 version and continue to use it.

FAQ
Q. If the mesh or leather is damaged or stretched, is it possible to replace the parts?
A. The high-quality synthetic leather used for the headrest is made exclusively for CT 3.5, providing high durability and softness. If you wish to replace the leather due to damage depending on usage intensity or frequency, you can purchase headrest covers in various sizes at a low price on the official website.
For fabric covers, they can be washed separately, but machine washing and using a dryer may damage the fabric, so we recommend hand washing only the stained area and air drying.
The mesh, based on high-tril material, is resistant to contamination and has excellent resilience, resulting in minimal deformation. You can enjoy the unique elasticity and cushioning of the mesh for a long time. High-end mesh, by its nature, becomes softer and more comfortable to fit the user's body shape after a period of use, maximizing comfort through a loosening phenomenon (relaxation), similar to how new shoes adapt to your feet.
However, if you wish to replace the seat or backrest due to firm cushioning or loosening that occurs during use, you can purchase integrated 1:1 replacement parts with the frame at a low price on the official website. Self-repair is also fully possible.
Q. Aren't A/S parts expensive?
A. For customer service, most A/S parts are offered at discounted prices compared to the retail price.
Q.CT 3.5What kind of chair is it?
A. The Worktoy CT3.5 is an idea convergence model newly planned with over 10 years of accumulated chair development know-how, and is a representative high-end chair 100% made in Korea, completed after three upgrades.
Q. How durable is the CT3.5 mesh?
A. The mesh of the Worktoy CT3.5 is a premium mesh with excellent durability that can be used for more than 10 years. When new, it has very strong tension, and a natural loosening of about 3-5% occurs with use, providing comfortable seating that fits the user's body. Compared to ordinary chairs, the mesh has excellent resilience, and unlike fabric or leather chairs where the padding sinks over time, the elasticity is maintained even after long use.
Q. I weigh a lot. What is the load capacity?
A. The maximum load capacity is 115kg, and the safe load is 110kg.
Abnormal use not described in the user guide, such as lying down with the backrest reclined and accelerating into the chair, can cause product damage. Please refrain from such actions.
Q. What is the free warranty period and coverage? Can I get after-sales service after the free period ends?
A. Strength parts and functional parts: 2 years free / Consumable parts: 1 year free
Warranty coverage: Excludes natural fraying or loosening of the mesh, arm pads, casters, cylinders, and other consumable exterior parts that occur during use, except for the tilt mechanism.
If the functional operation of the mechanism does not work. Even after the free warranty period, if it is confirmed to have been sold by Smith S3, paid after-sales service is available. If it is a used product, purchased overseas, or the buyer cannot be verified, after-sales service is not available.
Q. There is play and noise in the backrest and armrest.
A.There may be back-and-forth play in the fixed backrest, play in the seat slide, and basic play in the height and pad of the armrest. These are not product defects but are normal play designed for easy and smooth operation. The operational noise and play from these parts are natural phenomena, so please use the product with confidence.
Q. The bolts have loosened and the chair wobbles after use.
A. Due to the nature of chair products, various parts are assembled with bolts, and each connection uses a structure to prevent bolts from loosening easily. However, depending on years and frequency of use, bolts may naturally loosen.
In this case, simply tighten the bolts clockwise using the hand tool (6mm hex wrench) included with your initial purchase.
Q. I think the chair is not level.
A. If the floor surface is not completely level, or if the desk you are using is bent, the left and right armrests may appear uneven. Please refer to these cases. Due to the nature of chair products using over 100 connecting parts, a left-right balance error of 10-15mm may occur. Due to the structural characteristics of the cylinder's outer shaft, slight left-right or horizontal errors in the seat may occur.
Q. How do I clean it?
A. With mesh chairs, dust tends to fall under the seat. Please remove dust regularly using a duster. While mesh cannot be fully washed, if it gets partially stained, gently wipe the affected area with a neutral detergent, then remove the detergent with a clean and soft cloth, and let it air dry completely before use. For leather materials, you can maintain them with commercially available sofa or leather cleaners for longer use.
Q. I would like to visit and see the product in person. Is there an offline store or showroom I can visit?
A. You can experience it at the Smith S3 Pangyo Showroom (15, Seolgae-ro 14beon-gil, Sujeong-gu, Seongnam-si). We are also preparing for you to experience it at the offline 'Wadiz Space' during the project period.
