A seat cushion in high-density memory foam that moulds to the shape of your body and spreads the pressure when you sit for long periods. The rear cut-out leaves the coccyx free, the breathable cover zips off and goes in the washing machine, and the non-slip base keeps it in place on the chair.

✨ Why you'll love it

  • High-density memory foam that follows the shape of your body.
  • Rear cut-out for the coccyx and an ergonomic twin-seat shape.
  • Breathable cover with zip, removable and machine washable.
  • Non-slip base: it stays put on the chair.
  • For office chairs, car seats, wheelchairs and armchairs, in 3 colours.

Ergonomic memory foam seat cushion with coccyx cut-out

❓ Frequently asked questions

What is the cut-out at the back for?
It leaves the coccyx suspended instead of pressing it against the seat, so your weight rests on the thighs and buttocks. It is the typical shape of cushions for people who spend many hours sitting down.

Does it work in the car?
Yes, at around 43 x 36 cm it fits most seats and the non-slip base keeps it in place. It is also suitable for office chairs and wheelchairs.

Does it get hot in summer?
The cover is made of breathable fabric and the two side openings let the air through. If needed, the cover comes off for washing.

How do I wash it?
Undo the zip, slip off the cover and put it in the washing machine. Then fit it back over the memory foam cushion.

Is it a medical device?
No, it is a comfort item for home and office. It is no substitute for professional advice.
