Sit longer. Feel better.
U-shaped memory foam that takes the pressure off your tailbone and hips, on long drives and long workdays.
Posture scan
How long does your body sit on a hard seat?
Drag the slider to your usual day: commute, desk, sofa. Most of us are surprised.
Weight off the tailbone. Onto the thighs.
On a flat, hard seat your weight piles onto two small sit bones and the tailbone. The PostureSeat's contoured foam and U-shaped cut-out spread it across a much wider area, and leave your tailbone floating over the gap.
Built around how you actually sit.

Questions about size or your seat? Ask before you buy.
Before you order.
Which way round does it go?
The U-shaped cut-out goes at the back, under your tailbone. The thicker, rounded front supports your thighs.
Will it fit my car seat?
At 18.1 × 14.2 in it fits most car, truck and SUV seats, office chairs and gaming chairs. It adds about 3 in of height, so in a low-roof car check your headroom.
Is it firm or soft?
Both. The surface softens with your body heat and moulds to you; underneath it stays supportive so you don't sink to the seat. Give it a day or two to feel fully broken in.
Can I wash it?
Yes. Unzip the cover and machine wash it on a gentle cycle, then air dry. Don't wash the foam itself; spot clean it if needed.
Does it help with back or tailbone pain?
It's designed to take pressure off the tailbone and hips and encourage a more upright posture, and many people find long sitting more comfortable with it. It's a comfort product, not a medical device, so if you have ongoing pain please see a doctor or physio.
What if something's wrong with it?
If it arrives faulty, damaged in transit or isn't what you ordered, message us within 14 days of delivery and we'll replace or refund it. Full terms in our return policy.
