A single-piece cushion with contoured seat support and integrated back support in a sculpted ergonomic shape. The seat section cradles and distributes weight while the back section rises behind the lower back, and a central relief cutout reduces concentrated pressure in the center. One piece replaces a separate seat cushion and lumbar pillow, built from high-density memory foam that holds its shape through daily use.

Everything You Need to Know
Every detail of the TENAX Memory Foam Chair Support Cushion is worth knowing. Here's a closer look...
Seat + Back in One Piece
+
- Most chair cushions are flat seat pads with no back support
- Most lumbar pillows support the back but do nothing for the seat
- This cushion combines both in a single contoured piece
- No stacking two separate products on the same chair
Central Relief Cutout
+
- The cutout in the centre of the seat section redistributes seated pressure
- Weight is spread toward the outer contours rather than concentrating in the middle
- The result is a more balanced feel across the full sitting surface
High-Density Memory Foam
+
- Dense enough to support body weight without bottoming out
- Responds to heat and pressure, gradually conforming to the sitter
- Returns to its sculpted shape after every use
- Does not flatten or lose its contour over time
Breathable Cover
+
- Textured fabric allows air to circulate during seated use
- Does not trap heat or moisture against clothing
- Reinforced stitching prevents wear at the seams and edges
- Removable for cleaning
Low-Profile Design
+
- Does not add excessive height to the seat
- The contour is sculpted rather than bulky
- Looks clean and intentional on an office chair rather than makeshift
- The three colour options blend into professional and home settings
Lightweight & Easy to Move
+
The compact design makes the cushion simple to reposition wherever seating comfort is needed.

Frequently Asked Questions
How is this different from a regular seat cushion?
+
A regular seat cushion is a flat pad for the seat only. This cushion has a contoured seat section and an integrated back support section in one piece. It replaces both a seat pad and a separate lumbar pillow.
Does it add a lot of height to the chair?
+
No. The low-profile contour adds support without raising the seat height excessively. The design is sculpted rather than thick.
environments such as office chairs, dining chairs, or home workspaces.
Does the foam go flat?
+
No. The high-density memory foam returns to its sculpted contour after every use and maintains its shape through regular daily sitting.
What is the central cutout for?
+
The cutout redistributes seated pressure away from the centre of the seat, spreading weight toward the outer contours for a more balanced feel.
Does it fit a standard office chair?
+
Yes. The 44 x 42 cm dimensions fit most standard office chairs, desk chairs, and dining chairs without hanging over the edges.
Is the cover removable?
+
Yes. The cover removes for spot cleaning or gentle washing. Do not machine wash the foam.
