18x16x3 Memory Foam Seat Cushion with Zipper,Chair Cushion with Non-Slip Backing,Breathable Office Chair Cushion/Cushion Lab/Wheelchair Cushions(Black Cover)

Purchased to place in a wheelchair. Is very firm but yet soft. Love that it came with an additional cover for between washes. Great buy for the money.

This seat cushion consists of 3-inch basic foam, with a thin satin-finish inner cover, and a rugged poly mesh outer zippered cover. I believe the original posting said this was memory foam, and there is still a reference to memory foam in the description. It is not memory foam as far as I can tell. It is more like the basic foam seat cushions used for stadium cushions, boating, golf carts, etc. That said, it is supportive, and holds its shape well. The outer cover is sturdy, well-finished/sewn, and breathable, with the mesh. The inner cover is very thin and fragile, and meant more as a dust cover. I accidentally sliced right through it when I was unboxing the cushion. The large size of the cushion is good for coverage, but too large to fit in most standard chairs and seats. All this to say, it's good if it's what you need, but not super versatile for a ton of applications.

Very good quality

Very thick and comfortable chair pad. My son uses it in his gaming chair. Very firm and adds height since it is so thick. Pretty big size....I had initially got it to use in a vehicle seat but it's too large for that.

I didn't realize this was a wheelchair cushion. The cover is not made of the best material. I was expecting a different kind of material, like most cushions have (fabric/canvas-like material). I will not be able to use it where I want it without an additional cover. The foam seems OK, but don't expect it to be like tempurpedic memory foam, it is firmer. Still, it may work well for some depending on where you want to use it.
