Inflatable Air-Cell Seat Cushion — Hollow Center & 36-Cell Anti-Slip

Comfort you can take anywhere. This inflatable air-cell seat cushion is its own pump — you press the cushion itself to inflate it, so there is no pump to carry — and it rests you on a bed of independent air pockets that spread your weight and ease pressure on your tailbone and sit bones.

Choose your style

• 36 Air Cells — 44 × 44 cm (17.3 × 17.3 in). Even, all-over support. The right answer for most desk workers and drivers.
• Hollow Center — 48 × 43 cm (18.9 × 16.9 in). A cut-out centre removes contact from the coccyx entirely. Usually the better choice for tailbone pain, post-surgery recovery and pregnancy.

How to use it

1. Close the air nozzle — the clear nozzle on the back of the cushion. If it is left open, the air will not stay in.
2. Open the inflate valve — the black flip-open cap on the back.
3. Press the cushion to inflate it. Press the air cells around 30 times. The cushion is the pump — no external pump, no batteries.
4. Set your firmness, then close the valve. Too firm? Press the red release button inside the inflate valve to let a little air back out. 60–80% full is the comfort sweet spot — not 100%.

To pack it away: open the air nozzle and press the cushion flat. The air is out in seconds — then roll it up and bag it.

Why you’ll love it

• No pump to carry or lose. The pump is the cushion. Press it to inflate, then set the firmness exactly where you want it — any day you like.
• Air-cell pressure relief. Dozens of connected air cells flex with you and disperse pressure instead of concentrating it on the two points that ache.
• It keeps working while you sit still. Air moves between cells every time you shift, so no single spot carries your weight for hours — something a solid block of foam physically cannot do.
• Anti-slip base. A textured grip on the bottom keeps the cushion planted on office chairs, car seats and wheelchairs.
• Durable, all-weather build. A tough welded TPU core with a soft, breathable cover, rated from −22°F to 167°F (−30°C to 75°C) — it will not stiffen on a winter commute or soften in a car that has been baking all afternoon.
• Folds flat, travels light. Deflate and pack it into a bag for the office, the car, a flight or the stands.

Questions people ask

Which style should I pick?
Choose 36 Air Cells for even support across the whole seat — right for most desk workers and drivers. Choose Hollow Center if your pain is specifically the tailbone or coccyx, since the cut-out removes contact from that point entirely.

Is it hard to inflate?
No, and you do not need anything extra. Close the clear air nozzle, open the inflate valve, and press the cells about 30 times. It takes a minute.

Will it pop or leak if I am heavier?
The chambers are welded TPU, not thin PVC. The detail that matters is inflation level: fill to 60–80%, not bursting. An under-filled cushion has room to flex under load, which is more comfortable and far easier on the seams.

Does it go flat during the day?
No. The valve seals once closed. You inflate it once and top it up every few weeks, not every day.

Will it slide off my chair?
The base is textured for grip and holds on fabric office chairs, leather car seats and wheelchair slings. On an unusually slick surface, letting a little air out increases the contact patch and settles it further.

Is it hot to sit on?
Less than foam or gel. The channels between the cells stay open, so air keeps moving underneath you rather than sitting trapped against the seat.

Can I use it in a wheelchair all day?
Air-cell construction suits long seated sessions because pressure redistributes each time you shift. That said, this is a comfort product, not a medical device — if you are managing pressure injuries or a specific condition, check with your occupational therapist or physician first.

How do I clean it?
The cover comes off and is machine washable. Wipe the air cells with a damp cloth and mild soap, and let both dry fully before reassembling.
