AliMedSolid Seat Insert SSI with Cover, 16x16"

Insert fills the gap when seat sags. I cannot tie it to the wheelchair because I have to remove cuhshion and insert so I can fold up wheelchair when I go somewhere in the car. Works fine.

This has really helped me out so mush. When I sat in my wheelchair before, the sag in the seat would compress my hips after awhile, and cause lots of pain. Now with the seat insert, and a new memory foam cushion, it feels like sitting on a cloud. I highly recommend this for anyone who needs to sit for long lengths of time in a wheelchair. It also comes in larger with and depth sizes.
