Inside the cover

One moulded ring of memory foam

Unzip the cover and the whole cushion is a single moulded ring of memory foam at 45D density. There is no second layer and no board underneath, so the ring keeps its shape and the open centre stays open.

The cover

Crystal velvet, zip round the edge

The cover is crystal velvet with a soft nap that does not shed lint or pill, and a fine track zip runs the whole way round the side edge so the cover comes off the foam and is washed on its own.

  • Track zip runs the whole way round
  • Cover comes off the foam to be washed

Frequently asked questions

How big is the donut cushion?+
It is 42 cm across at the widest point, 38.5 cm from front to back and 6.5 cm deep. One size, and it arrives boxed at 48 by 40 by 8 cm.
Which way round does it sit on the chair?+
Set it flat on the seat with the shallow dip in the rim towards the back of the chair, so the opening sits in the middle of the seat.
Can the cover be washed?+
Yes. The track zip runs the whole way round the side edge, so the crystal velvet cover comes off the foam ring in one piece and is washed on its own.
What is inside it?+
One moulded ring of memory foam at 45D density. There is no second layer, no gel insert and no board underneath.
Will it fit a car seat or a dining chair?+
It is 42 by 38.5 cm, so the ring cushion sits flat on a car seat, a wooden dining chair or an office chair seat without hanging over the sides.
What colours does the donut pillow come in?+
Navy blue, mocha, dark grey and rose red. Every colour is the same ring, the same 42 cm size and the same crystal velvet cover.
