Had a coccyx injury a few years back and every chair since has been uncomfortable within the hour. This is the first cushion that fully removes the pressure — the channel is deep enough that the tailbone never touches. Bought one for home and one for the office.

“Had a coccyx injury years ago — every chair has been uncomfortable since. This is the first cushion where the tailbone takes no pressure at all. Bought a second one for the office within the week.” — Claire S., Edinburgh

Six months of hip and lower back pain from sitting at my desk. Tried a standing mat, different chair, stretching breaks. This cushion is what actually made a difference. The coccyx channel is the key — no pressure on the tailbone at all. Noticed it on the first afternoon.
I sit nine hours a day across two screens. My hip flexors and lower back were solid by midday every day. Two weeks with this and the afternoon stiffness has gone. The contoured sides are what I wasn't expecting — it holds you in the right position rather than just cushioning under you.
Bought the grey. Fits the chair and stays put, which was my main concern. The five-zone design does work — you can feel the different support areas, especially the coccyx channel. Took about a week to feel completely natural but now I notice immediately if I sit without it.
The height difference was the first thing I noticed. Suddenly my arms were at the right angle for the keyboard without adjusting anything else. My monitor looked different — at the right height for the first time. I didn't expect a seat cushion to change my whole ergonomic setup.
Got the green. Better looking than expected — subtle sage rather than anything medical. The cover has already gone through the wash twice with no issues. The foam has kept its shape completely.
Does exactly what it says. The memory foam takes a few days to break in but holds shape well after that. No shifting during the day. The hip relief is real — I stop noticing my hips by mid-morning, which is exactly what you want from a cushion.
Spent two weeks looking at ergonomic chairs costing £500 upward. This cushion and the lumbar support together sorted everything for under £80 total. The five zones sound like marketing until you sit on it and feel each one doing something specific.

Frequently asked questions
Will it fit my office chair?
Yes. The cushion fits any standard office chair, gaming chair, or upright seat with a flat or slightly curved seat base. The non-slip underside holds it in position without straps or fixings. It won't fit saddle-style chairs or seats with very pronounced side bolsters.
What's the difference between Light Green and Light Grey?
Colour only. Both variants are identical in shape, foam density, zone layout and cover material. The green is a muted sage tone, the grey is a neutral warm grey. Choose whichever suits your desk setup.
How firm is it?
Medium-firm. Dense enough to support sustained body weight without bottoming out, but it conforms to your shape rather than pushing back rigidly. Most people find it comfortable immediately — there's typically a few days of adjustment as the foam moulds to your seated position.
Does the coccyx channel actually make a difference?
Yes — particularly if you experience tailbone pressure or have a coccyx sensitivity or injury. The channel suspends the coccyx in mid-air so it carries no load from the seat surface. For people without coccyx issues, the channel still improves comfort by keeping the pelvis in a slightly forward-tilted, neutral position.
Is it suitable for all-day sitting?
Yes. That's what it's designed for. The memory foam density is chosen for sustained use — softer foams compress and lose support across hours; this one holds its structure through the full day and returns to its original form each morning.
How do I clean it?
The outer cover unzips and machine washes cold on a gentle cycle. Air dry or tumble dry on low. The memory foam insert should not be machine washed — spot clean with a damp cloth only.
