Memory Foam Seat Cushion — Coccyx Support for Office Chairs
Memory Foam Seat Cushion — Coccyx Support for Office Chairs
Eight hours in a chair shouldn't hurt.
Most office chairs put your full body weight straight onto the tailbone. This cushion cuts that channel out entirely — the pressure moves to your thighs and sit bones, where it belongs.
The U-cut is the whole point
A section is removed under the coccyx so nothing touches it. That single design choice is what separates a real orthopaedic cushion from a decorative pad.
Memory foam that holds its shape
High-density foam moulds to you in about a minute and returns to full height when you stand. It won't flatten into a pancake after three months.
Ice-silk cover, no swamp
The breathable ice-silk surface stays cool through long sessions — a real problem with dense foam and the reason most cushions get abandoned in summer.
Stays where you put it
A non-slip base grips the seat instead of sliding forward every time you shift.
Who it's for
- Desk workers doing 6+ hours seated
- Drivers, couriers and anyone on long commutes
- Recovery after childbirth or surgery
- Anyone with tailbone, hip or lower-back discomfort when seated

Questions we get asked
Will it fit my chair?
At 41 × 38 cm it fits standard office chairs, dining chairs, car seats and wheelchairs. Measure your seat pan first if your chair is unusually narrow.
How long until it stops feeling firm?
Memory foam is temperature-reactive — give it 3–5 minutes of body heat on first use, and a few days to fully break in.
Does it work in a car?
Yes, and it's one of the most common uses. Note that it raises you roughly 8–10 cm — check your mirror and headroom.
Is this a medical device?
No. It's an ergonomic seat cushion that relieves pressure. For persistent or severe pain, speak to a doctor or physiotherapist.
