good for back support
the two foam sheets are working out well as back cushions on my sofa to firmly support my back. the slight curvature is very helpful for back support. i was surprised that they were bare foam, but i will put a pillow case over them.
Verified Purchase
They did exactly what I hoped they would do. They make a used sofa firmer and more comfortable. Very satisfying!

Excellent padding for under you couch cushions. They stay in place %26 give you a little stability in your couch!
