Right now it’s some sort of memory foam mattress, he said it’s a Zinus - definitely low density as it compresses very easily.
I feel like adding the wedge would help quite a bit. I did a small test run with this foldable foam bed my partner has and it did change the feel of the bed - made it firmer with less compression.
I’m thinking about purchasing but they don’t list what sort of foam they use. If it’s low density, it will wear out pretty quickly.
Edit: I found a brand that lists that they use high density foam with their wedge. https://www.avanacomfort.com/mattress-elevator.html?Height=2508&size=792
My only huff is that they don’t list what sort of foam they use. If it ends up being low density it will be useless.
