Why it feels different
Tailbone cut-out
The open U at the back keeps your tailbone off the seat.
Firm memory foam
High-density foam that adapts to you and keeps its shape.
Better sitting posture
Contoured shape that helps you sit more upright.
Washable cover
Breathable mesh cover that zips off and goes in the wash.
Why the U-shape works
Open U cut-out
The U-shaped gap at the back means your tailbone does not press on the seat while you sit.
Contoured surface
Gentle curves cradle your thighs and spread your weight more evenly across the cushion.
High-density foam
Memory foam that moulds to you and bounces back, day after day, instead of going flat.

Good questions, honest answers
Will it fit my chair?
It measures about 45 x 35 x 7 cm (17.7 x 13.8 x 2.8 in), which fits most office chairs, car seats, dining chairs and wheelchairs.
Which way round does it go?
Put the open U cut-out at the back of the seat, then sit all the way back so your tailbone sits over the gap.
Is it soft or firm?
It is medium-firm high-density memory foam: soft enough to be comfortable, firm enough not to bottom out. Many people need a couple of days to get used to it.
Can I wash it?
Yes, the mesh cover zips off and can be machine washed on a gentle cold cycle. Let it air dry. The foam itself should not be washed.
Does the new foam smell?
New memory foam can have a light smell when you unpack it. Leave it in a ventilated room for a day or two and it goes away.
Will it help with my back or tailbone pain?
It is a comfort product, not a medical device. It takes pressure off the tailbone and helps you sit more upright, which many people find more comfortable. If you have ongoing pain, please talk to your doctor.
When will my order arrive?
Orders ship free to the US and arrive in 6–12 business days (Monday to Friday), with tracking by email.
What if I change my mind?
You can return unused items in their original packaging within 30 days of delivery. If your order arrives damaged or wrong, we replace it or refund you at no cost.
