Young Brunette Girl Reveals On Bed Mattresses

The typical mattress sold in North America today is an innerspring; however interest in all-foam beds and so-called hybrid beds—which include an innerspring plus high-end foams, such as visco-elastic or latex, in the comfort layers—is increasing. In Europe, polyurethane foam cores and latex cores have long been popular and make up a much larger proportion of the mattresses sold.
History
Neolithic period: The mattress and bed are invented. Beds are raised off the ground to avoid drafts, dirt, and pests. The first mattress probably consists of a pile of leaves, grass, or possibly straw, with animal skins over it.
