Purchased this to replace the existing cushion in my camper dinette. Very firm....exactly what I was looking for! It is a little heavy due to its density, so if you're concerned about the added weight in your camper, this will definitely add a few pounds.
The service department was also great. I ordered a big piece, so Foam 'N More could not ship it in one piece. They did communicate well and gave me the option to cut it in half (and pay additional shipping) or cancel the order altogether. I decided to have it cut in a way that still worked for the dimensions I needed. Win!
