GoTo Foam 4" Height x 30" Width x 84" Length 43ILD (Firm) Upholstery Cushion Made in USA

It work for my couch! Great firm foam.

Great stuff easy to work with, sooooo comfortable

I used this to add support to sofa cushions. It works very well and easily trimmed to fit with electric knife. Sofa feels like brand new. No more sinking into the sofa cushions and struggling to get back out!
