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.
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.

THE PROBLEM
When you sit down, nearly all your weight lands on the tailbone area. The cut-out at the back leaves that point in the air and spreads the pressure to the sides: the spot that hurts most after hours of sitting stops taking the load.
✓ The cut-out frees the tailbone area
✓ Pressure spreads across the whole base
✓ Made for long sitting sessions
MEMORY FOAM
High-density memory foam: it sinks to the shape of your body while you are sitting, holds you up, and comes back to its full volume when you stand. It adjusts to you every time you sit down, not the other way round.
✓ High density, returns to shape
✓ Adapts to your body, not the reverse
✓ Breathable fabric, no trapped heat
FROM THE OFFICE TO THE CAR
Removable zip cover, machine-washable, non-slip rubber base so it does not slide off the chair, 43 × 36 × 8 cm and under a kilo. From the office chair to the car, with nothing to set up.
✓ Removable, machine-washable cover
✓ Non-slip rubber base
✓ 43 × 36 × 8 cm · 700–900 g
PROTECTED PURCHASE
From day one. The cut-out at the back leaves the tailbone in the air and the pressure spreads out to the sides, so hours of sitting feel different. The memory foam needs a few minutes to take the shape of your body: after that it adjusts to you every time you sit down.
Yes, and that is one of its big advantages. It measures 43 × 36 × 8 cm and weighs between 700 and 900 g, so it fits an office chair, a car seat or a wheelchair equally well. The non-slip rubber base keeps it in place and you can carry it from one to the other without setting anything up.
The foam is high-density memory foam, not a fibre filling: it gives under your weight while you are sitting and comes back to its full volume as soon as you stand up. That is why it holds the same support day after day instead of sinking.
Yes. The cover is removable with a zip and machine-washable, so the cushion stays clean with no fuss. The fabric is also breathable, which avoids that trapped-heat feeling after several hours of sitting.
All three go with everything: navy is the classic one for the office, black disappears on a car seat and grey suits living rooms and light spaces. All three have exactly the same memory foam and the same washable cover.
Yes. Every order is delivered free of charge, whatever the basket total. Full details in the Shipping Policy.
