Review: We are happy couch potatoes! - Great quality - I ordered this foam piece as a replacement for cushions that my dog chewed up as a puppy. Now, that same puppy is a 3 year old beagle, and it quickly became his favorite napping spot! The foam is super firm - ideal for extending the value of my investment. Because I am lazy, making a sofa “bench,” the project was easier, added stability and functionality (and few opportunities for chewing). Though I would have preferred double thickness, I simply ordered another foam piece and it gave me the thickness I desired. My dog and I are happy couch potatoes!
Review: Excellent Foam - Cushioned my dinette cushions. So much better than the foam they came with.
