This post is all about, all latex mattresses! They are the least common of the bunch, and are outsold by thousands of units by other mattress types. Sure, latex is used a lot in hybrid mattresses, or as a mattress topper. But actual mattresses made just of the stuff? Not so much. Does that mean you should write them off as being no good? Absolutely not. In fact, after researching different mattress materials and how they perform, I think latex mattresses are highly underrated.
