One of America's top three mattresses Has arrived.




Many brands talk about 'tradition,' but 70 years is more than just the passage of time.
Therapedic, which took its first step in the United States in 1957, was obsessed with what was considered impossible at the time with existing technology,
The 'ergonomic support' that was thought to be unattainable.

The data accumulated by being responsible for the sleep of millions and tens of millions of people in over 55 countries around the worldDoes not lie. The reason Therapedic is loved worldwide isNot because of flashy advertisements.For 70 years, the relentless craftsmanship has been dedicated solely to researching,'How can humans fall asleep as freely as possible from gravity?'

















I can say with confidence that a luxury American mattress
At this price,
Today will be the first and last time you experience it.


A comfortable and soft mattress may have relatively weak 'vertical support' that pushes up the overall load.
Your body sinks deeply into the mattress,
Which becomes the main culprit in breaking the natural S-curve of the spine.


The lower Bonnell springs are the pillars of the entire mattress.
Hundreds of springs are connected to form a massive 'energy plate.'
This powerfully bounces back the load pressing from above, ensuring that the comfort created by the mini pockets does not turn into 'sagging'.It serves as a strong protective barrier.

On top of the powerful support provided by the Bonnell,The mini pocket closely fills the delicate curves of the body (shoulders, waist, pelvis).
It densely fills in the gaps. When the firmness of the Bonnell meets the comfort of the mini pocket,
Only then,'The waist feels comfortable and the skin feels like clouds'An ideal sleep environment is finally achieved.

It means the energy generated when the spring is compressed and restored is overwhelming.
Even with a slight toss, the spring instantly supports your body,
Minimizing energy consumption during deep sleep.


Serapedic's Bonnell spring is a right-turn coil wound six times.

The optimal number of turns provides both flexibility and deep support.

When you first touch it, it gently absorbs your weight, and the deeper you press, the stronger it pushes back,

Implementing 'progressive support'.

Pocket springs are enclosed in nonwoven fabric pockets, which can wear out over time,
And the springs may come loose. However, Bonnell springs have an open structure that maximizes breathability, and they boast remarkable durability, maintaining their original elasticity even after 10 years.

Each spring is individually placed in a nonwoven fabric pocket for independent movement.
Because the springs move independently, they perfectly block the movement of the person next to you.


Mini pockets, which are smaller in diameter and more densely arranged than regular pockets, follow the body's curves.
We support with more detailed segmentation. If the Bonnell provides the main framework,
the mini pocket perfectly eliminates pressure points that block blood circulation by filling the gaps between muscles.

Each mini pocket is contained in an independent pouch, so the movements of the person next to you are not transferred to you.

A hybrid single spring structure combining Bonnell and pocket springs,
is used by domestic and international brands in high-end premium mattresses,
but they cannot match Serapedic's hybrid double spring structure.



Placed directly above the mini pocket springs, it maintains the soft characteristics of the mini pocket,
while serving as an 'elastic base' that provides firm support to prevent your waist from sinking too deeply.

While low-priced mattresses on the market are filled with cotton or low-density foam, Serapedic uses high-density HR foam,
to create a balance that feels like floating on a cloud but keeps your waist comfortable.


Some mattresses on the market indiscriminately use recycled fibers of unknown origin (synthetic fiberfill) or harmful fillers with fluorescent brighteners to cut costs. Serapedic completely rejects this.

The antibacterial function, which fundamentally blocks the occurrence of viruses, bacteria, and everyday germs, reduces any possibility of unpleasant odors.


Sanitize's antibacterial and deodorizing hygiene technology has been recognized at the global TECHNOLOGYAWARD,
proving its reliability.

We never mix waste fibers or recycled fibers,and only use
Huvis's original virgin yarn (100% genuine fiber)..We directly applied the eco-friendly antibacterial processing technology of Switzerland's Sanitized AG to Huvis's genuine yarn,
to create 'Sani-Padding.'



Even children with atopic dermatitis and wives with sensitive skin can enjoy 100% pure and clean comfort inside and out.Let them breathe easy and safely on the bed.


Not only does it evenly distribute pressure according to the body's curves, but the foam air channels formed between each layer quickly release heat generated during sleep, maintaining the optimal sleeping temperature.

This is the core layer that protects the strong elasticity of the springs between the Bonnell springs and the upper padding.
It prevents the steel springs from directly touching and causing friction or damage to the padding and mini pockets.
It also dramatically blocks internal mattress noise and firmly
supports the overall levelness of the mattress, completing its foundational strength.



The mattress fabric is not just a cloth that covers the surface. It is the 'second skin' that first absorbs moisture and heat released from our bodies during sleep and comes into direct contact with the skin for eight hours.
It is the 'second skin' that first absorbs moisture and heat released from our bodies during sleep and comes into direct contact with the skin for eight hours.
Serapedic rejects the stuffiness of chemical fibers and has found the optimal ratio designed by nature.

Linen extracted from flax plants has breathability that cannot be compared to synthetic fibers.It absorbs sweat very quickly and dries exceptionally fast, keeping you cool in the hot summer and preserving body heat for coziness in the cold winter.


Rayon, a natural regenerated fiber extracted from wood pulp, boasts a softer and smoother feel than cotton.It helps children or adults with sensitive skin fall into a deep sleep without irritation.

Over 20 types of arylamines, which are skin carcinogens, and formaldehyde, which causes respiratory diseases,
were not detected at all. We manage it with stricter standards than those for infant bedding.


It maintains a mildly acidic to neutral range, most similar to human skin.
It is carefully designed to keep your skin's balance from being disrupted while you sleep.



Serapedic mattresses are made through rigorous testing.



Low-cost mattresses use a formal finishing method, and regular mattresses use a single foam guard.
However, Serapedicmaintains a consistent edge guard with a lower vertical felt and an upper hard foam guard.

A thick steel wire that ties the perimeter of the spring unit vertically forms the primary framework.


Instead of regular foam,thick felt is placed verticallyto wrap and secure the entire height of the spring unit. This acts as an 'armored outer wall' for the mattress, completely blocking horizontal movement of the springs and preventing the mattress from losing its shape over time.


On the upper part, where the soft mini pocket springs are located, a highly supportive65mm thick hard foam guard is placed.

The area around the mini pockets is surrounded by thick and firm foam, perfectly preventing the springs from popping out or shifting even when sitting or lying on the edge.

Tens of thousands of stitches tightly hold the side fabric and internal materials, physically preventing the inner materials from shifting or bunching to one side.


Many people mistakenly believe that the higher the mattress, the better and more expensive it is. In the bedding industry, there is a widespread marketing tactic of indiscriminately stacking internal materials to increase height and raise the selling price, known as 'puffed-up height.' However, excessively high mattresses have a fatal flaw: they kill the elasticity of the springs and, over time, the weight of the internal materials accelerates sagging.



This is the height of the double spring unit, combining a lower Bonnell spring (19cm) and an upper mini pocket spring (7cm). It is designed to perfectly support the body's weight while providing immediate resilience.
It is both the minimum and maximum space required.


It is the thickness of the support layer that allows you to feel the vitality of the springs while providing cloud-like comfort.
It is the thickness of the support layer.Overly thick internal materials disperse the support of the springs, causing the lower back to sink deeply,
and reduce breathability, hindering heat dissipation during sleep.


Flashy and elaborate patterns tend to become tiresome quickly. Serapedic, even as time passes
We pursue 'minimalist classic' for enduring value.

The unique luxurious and natural texture of open linen fabric is not an artificial gloss,
but creates a subtle and refined atmosphere.The Serapedic exclusive logo and pattern embroidery, completed with tens of thousands of precise stitches, not only serve an engineering role in firmly shaping the product, but also provide 'three-dimensional details' typically seen in luxury bags.

We hold more than 50 global licenses worldwide, and in the highly demanding
U.S. market, we stand shoulder to shoulder with Sealy and Simmons,ranking in the official brand power Top 3as recorded.

Serapedic's patented technologies, such as the independent double-layer structure of Bonnell and mini pocket springs, and double-sided guards,
along with our customer-centric philosophy, have fundamentally changed the sleep of millions worldwide over the past 70 years.

We have implemented the strict technical standards (Standard Specification) of the U.S. headquarters
with zero margin of error, not even 1mm.
