Takes pressure off your tailbone
A U-shaped cutout at the back means your coccyx isn't pressed into the seat, while the foam spreads your weight across your thighs.
Memory foam + breathable mesh
Sit longer.
Feel better.

Your chair wasn't built for an eight-hour day.
Most seats are a flat pad on a hard base. This one is shaped around how you actually sit.
Breathes while you sit
A 3D air-mesh cover lets air move through the fabric, so it stays more comfortable than a solid seat pad on long days.
Keeps its shape
Contoured memory foam springs back after every sit — higher at the back, lower at the front, so it supports you without pushing you forward.
What's inside
Simple, and built to last.
A supportive memory foam core inside a breathable cover you can take off and wash.

Questions
Will it fit my chair?
At 40 × 30 cm, with 6 cm of memory foam, it fits most office chairs, car seats, gaming chairs and dining chairs. The non-slip dotted base stops it sliding around.
How long does delivery take?
Delivery is free and tracked. Orders usually arrive in 5–9 working days. You'll get a tracking link by email once it ships.
What if it isn't right for me?
Send it back within 30 days of delivery for a full refund. See our delivery & returns page for how.
How do I clean it?
Unzip the mesh cover and machine wash it on a gentle cycle. Don't put the foam in the machine — just air it out or spot-clean it with a damp cloth.
Which colours can I choose?
Black, Blue or Grey. Pick your colour just above the Buy button.
Is it a medical product?
No. It's a comfort cushion designed to reduce pressure while sitting. If you have ongoing back or tailbone pain, please speak to a healthcare professional.
It smells a bit when I open it — is that normal?
New memory foam can have a mild smell for a day or two. Leave it somewhere airy out of the packaging and it fades quickly.
