Actually here is the source of my uncertainty re: the base foam. This post refers to the use of a 2.35lb foam in the base of an Ultimate Dream mattress. The post concerns the Ultimate Dreams Latex mattress. Are you telling me that they use a different base foam (2.35lb vs. 1.5lb) in the latex vs. the gel Ultimate Dreams mattresses?
Thanks
