NOVA Medical Products Gel & Memory Foam Seat & Wheelchair Cushion in 8 Sizes (from 16” x 16” to 18” x 24” Extra Wide), Comfortable & Durable Everyday Seat Cushion with Removable Water Resistant Cover, 2” or 3” Thick, Black

I'm a big guy. 6'1 and 260 lb. My office chair did not have enough padding in the seat and this has really helped... I like the velcro straps to hold it in place and after around 90 days of use it is still holding its shape and comfortable. The 2-in thickness is perfect for me but if you want to raise your seating position you can get the thicker one.

Have to keep rotating. Person sitting in wheelchair says very uncomfortable and no air circulation.

I bought another brand cushion earlier, and it smashed flat within a few days when used by a hefty guy. This one is sturdier and is holding up so far. I recommend it!

It is to hardo to sit in all day for a disabled person I will need to look for something else.

The foam seat of my computer chair gave out and having it reupholstered or replacing the chair is not an option at this time and this cushion did the trick. Very comfortable.
