I love my queen size MF, it is 7 years old and came with a 20 yr. warranty. It is about 10 inches thick, extremely comfortable, zero transfer movement, no squeaks, super comfy and I can’t remember the brand but it is a well known CA. mattress manufacturer. I am not with my bed in the moment but…brand aside, I couldn’t be happier with mine. They do retain heat so can be extra warm at times.
