Description
The Star Stabil-Air is a single chamber air cell wheelchair cushion from Star, now part of Etac. Every air cell holds a soft foam cylinder, and the cushion carries two cylinder heights: the outer rows are taller, while the cylinders under the buttocks, coccyx and legs sit lower.
Etac calls that lower inner row an anatomically shaped secondary layer of skin protection. One valve sets the whole cushion. These are 4 in cells, and an occupational therapist or physiotherapist sets the air level in a seating assessment. The air cushion range covers the other chamber options.
Who is it for?
The foam cylinders give the cushion a firmer, more stable feel, and Etac says the interconnected cells readjust as the user moves in the seat. The maker prints no maximum user weight: every item in the table reads Unlimited.
Which size fits the chair?
The 4 in items run 13.5 x 13.5 in to 21 x 21 in, in the maker's seat width bands of 12-14, 14-16, 16-17, 17-19 and 19-21 in. Etac publishes no 4 in item past 21 x 21 in, so send us the seat width and depth: we confirm the maker item, and a larger seat is quoted on request.
How does the air work?
The cells are interconnected in one chamber, so a single valve adjustment sets the whole surface rather than balancing cells one at a time. Etac says the cylinders hold a considerable amount of air, for envelopment.
Covers, care and returns
The cushion comes with a StarLock cover. Clean it with a 70% disinfectant solution, and hand wash at 40 C (104 F) maximum. A used cushion, or one that has touched the skin, is not returnable. Read the return policy.
Delivery and service
We set the air level and fit the cushion at delivery through a wheelchair configuration. Book a free home assessment if the chair should be seen at home, and our service team looks after what we sell.

Frequently asked questions
What is inside the air cells?
A soft foam cylinder in each cell, taller at the outer rows and lower under the buttocks, coccyx and legs.
How many valves does it have?
One. The Stabil-Air is a single chamber cushion.
Can I order a width wider than 21 in?
Send us the seat width and we confirm it with Etac: the published 4 in items stop at 21 x 21 in, so a larger size is quoted on request.
Is the Star Sentinel part of the cushion?
No. The Sentinel is a separate powered accessory, and the cushion ships with its StarLock cover.
