YOUFIThick Memory Foam & Gel Seat Cushion, 18"X16"X4" Large Chair Cushion for Wheelchair Mobility Scooters, with Non-slip Bottom and Carry Handle (Blue)

I purchased this for my wife's wheelchair. She is only 4 foot 11 and weighs 86 lbs. Her wheelchair is the 18 inches wide blue Drive Wheelchair sold here on Amazon. The cushion is thick and fits nicely into the seat of the chair. It would not fill the entire seat area of a larger wheelchair. As I said, it is thick and has those typical gel cushion properties. It provides more comfort than the canvas seat of the chair alone. This is nice for longer periods of time sitting in the chair. The covering is a nice color of blue and seems to be pretty heavy duty. I think it will wear well. The cushion has a strap across the back for taking it out of the chair and to carry it. The strap is not a real necessity, but it is a nice addition. The only thing I don't like is the chair cannot be folded up with the cushion in it. This is just a reality and has nothing to do with the cushion itself. But it is something to be aware of. Every time you load or unload your chair into a vehicle, you will have to contend with removing the cushion, storing it somewhere, and then reinstalling it when you take the chair out of the vehicle. I think this is a quality product and I do recommend it.

I like the higher firmer support

Well made, comfortable. Fits perfectly in my drive 18" wheelchair.

Ok

I got this for an office chair that I sit in for about 10-12 hours every day. It started off great, it was very firm (almost too firm), gave me the added height I needed, and fixed the back pain I had from my chair. Then suddenly after about 8 months, it was no longer firm. It is very squishy now, and my back pain has returned. I don't want to keep spending $50 on pads that don't even last 1 year.
