Coccyx cushion on an office desk chair while working at a laptop
For the hours at a desk

An office chair cushion for the hours you spend sitting

Most desk chairs are built to look right rather than to be sat in for seven hours. The pad flattens, the front edge starts to make itself felt behind your thighs, and by mid afternoon you are shifting every few minutes. This sits on top of the chair you already own and gives you a moulded memory foam surface instead of a tired flat seat.

  • Sits on the office desk chair you already have
  • Memory foam takes your shape, then comes back
  • Moulded hip and thigh channels keep you central
The deep U shaped tailbone cutout at the rear edge of the coccyx cushion
Why it is shaped like that

The U shaped cutout is what makes it a coccyx cushion

The rear edge is cut away in a deep U. Sit down and the tailbone sits over that open gap with nothing underneath it, while the two raised pads either side take the load through the sit bones instead. That one shape is the whole difference between this and a flat pad, and it is why a coccyx pillow is built the way it is.

  • A deep U shaped cutout in the rear edge
  • Two raised side pads take the load
  • 12 cm at the raised back edge, 9 cm at the front
Memory foam seat cushion on a wooden dining chair in a bright kitchen
It moves with you

A memory foam seat cushion that moves from the desk to the dining table

Hard dining chairs are the ones people give up on first. Lift the cushion off the desk chair, drop it on the dining chair and it behaves exactly the same way. It carries in one hand, it goes in the car for a long drive, and it looks like a cushion rather than a piece of equipment sitting in the middle of your kitchen.

  • Dining chairs, desk chairs and car seats
  • Light enough to carry in one hand
  • Four colours: black, grey, green or pink
The coccyx cushion measures 49 cm wide by 41 cm deep and 9 to 12 cm high
49 x 41 cm

Sized to sit on the chair you already own

It measures 49 cm across and 41 cm from front to back, 9 cm deep at the front and 12 cm at the raised rear edge. That covers a standard office chair seat without spilling over the sides, and it still sits properly on a dining chair or a car seat. There is one size and it is the same for every colour, so there is nothing to measure before you order.

  • 49 cm wide, 41 cm front to back
  • 9 cm at the front, 12 cm at the raised rear edge
  • One size, identical across all four colours

Zip it off and wash it

The cover comes off and the base grips the seat

A zip runs around the base of the cover, so the whole cover lifts off the foam in one piece and goes in the wash when it needs to. Turn the cushion over and the underside is a dark anti slip panel covered in raised grip dots. That is what stops it creeping forward every time you stand up and sit back down.

  • Zip off cover, washable, goes straight back on
  • Raised grip dots across the whole underside
  • Only the cover washes, the foam core stays put

Small change.
Real comfort.

Sitting still for eight hours is the part nobody plans for. This is the small change that makes the chair you already own worth sitting in.

Frequently asked questions

Will it slide about on my office chair?+
No. The whole underside is a dark anti slip panel covered in raised grip dots. It holds on a fabric desk chair, on a wooden dining chair and on a car seat, so it stays where you put it instead of creeping forward as you shift.
Will it fit my chair?+
It is 49 cm across and 41 cm from front to back. That sits on a standard office desk chair seat without overhanging, and it fits a dining chair or a car seat just as well. There is one size, and it is the same for all four colours.
How firm is it, and will it go flat?+
It is memory foam, so it gives for the first few seconds, takes your shape and then holds it. Firm rather than soft, which is the point of it. Stand up and it returns to its moulded shape ready for the next time you sit down.
Can I wash it?+
Yes. The cover unzips around the base and lifts off the foam in one piece, so it washes on its own and goes back on afterwards. The memory foam core itself stays out of the wash.
Does the back pillow come with it?+
No. This listing is the seat cushion on its own. The matching lumbar back pillow is a separate product and is not included here, so what arrives is one cushion in the colour you choose.
Which way round does it go on the chair?+
The deep U shaped cutout goes at the back, nearest the chair back, with the raised rear edge behind you and the lower sloped edge at the front under your thighs. The dark grip panel faces down onto the seat.
