Memory Pillow seat cushion

We created this pillow with one simple goal: to make prolonged sitting truly more comfortable.

We tested various shapes, sizes, and filling densities to find the perfect balance between support and comfort. The result is an enlarged pillow compared to alternatives, which evenly distributes weight across the surface and prevents the body from sinking into a soft base.

We paid special attention to the tailbone area. The U-shaped cutout at the back of the pillow reduces direct pressure on the tailbone and creates extra space in the sensitive area.

The 46x51 cm size provides an increased support area. The pillow supports not only the central part of the pelvis, but also the thighs, making it suitable for long computer work, car trips, and other situations where you have to sit for a long time.

The goal was simple: to genuinely increase sitting comfort and reduce back strain, rather than just creating another layer between the chair and you. Enjoy!

With love,

The 46x51 cm size provides a large contact area with the body compared to standard compact cushions. Thanks to the increased width, the pillow supports the pelvis and thighs, not just a small central seating area.
The 13 cm height and dense Memory Foam create resilient support that adapts to body shape under load.
The pillow is primarily designed for prolonged sitting — during computer work, studying, travel, and other daily tasks.

U-SHAPED CUTOUT FOR TAILBONE
At the back of the pillow, there is a U-shaped cutout.
It creates free space directly under the tailbone, reducing contact of this area with the seat surface. As a result, the load is redistributed to adjacent areas of the pillow.
This design can be especially useful for people who spend a lot of time sitting and want to reduce pressure on the tailbone area.

DENSE MEMORY FOAM
Inside, dense memory foam is used.
The material gradually adapts to body shape under the influence of weight and pressure while maintaining the necessary support.
The filling density provides resilient support that differs from a regular soft cushion into which the body quickly sinks.

ENLARGED XL SIZE
46x51 cm is an enlarged format designed to support a larger body area.
The pillow fits most office chairs, car seats, gaming chairs, and other seats where extra comfort and support are needed.
The increased area helps distribute weight between the pelvis and thighs.

COMFORT DURING PROLONGED SITTING
The ergonomic shape helps distribute pressure over a larger surface area.
This can make long computer work, car trips, and other periods of prolonged sitting more comfortable.
The pillow can be used at home, in the office, in a car, or anywhere else where extra seat support is needed.

BREATHABLE REMOVABLE COVER
The outer cover is made of breathable material and is completely removable with a zipper.
The cover can be removed for cleaning and washing without washing the filling itself.
This helps keep the pillow clean even with daily use.

CONVENIENT TO CARRY ALONG
A built-in carrying handle is provided on the side.
The pillow is easy to move between the office chair, car, home, and other places of use.
No need to buy a separate pillow for each chair — you can take it with you.

FOR OFFICE, CAR, AND GAMING CHAIR
The pillow is suitable for:
office chairs;
computer and gaming chairs;
car seats;
home chairs;
wheelchairs;
long trips;
computer work;
studying and other tasks requiring prolonged sitting.

Please note: the effect of use is individual. The pillow is designed to increase comfort and reduce pressure while sitting, but it is not a medical device and does not replace a doctor's consultation.
