MOSAIC Cushion, Heavy Duty, Inflatable Seat Cushion for Office Chair, Wheelchair, Cars, Home Living, & Back Pain Support, Adjustable Cushion with Stretchable Cover & Non-Skid Bottom, 18" x 16"

This was really helpful and comfortable for my Mom's last year. Easy to clean

Exactly what I ordered it for, stops the wife having pressure sores!

This is great it's really nice takes a little just so to get the level right the cushion behaves a bit like those mattresses that have air pumps to vanity the pressure of the surface As you move and lean the air in the cushion moves between the chambers so you feel floaty and it feels great over bumps really helpful

This cusion stopped holding air by sept 2025 so basically lasted 5 months

Very comfortable. It slowly adjusts if you lean to one side and this can make it difficult to get level. It so perfectly fits your bottom that you have to check to see if your wallet has fallen out of your back pocket. Velcro keeps the cushion in position.
