High density memory foam

Consumer surveys show that memory foam mattresses have the highest owner satisfaction in the industry. It was first used by Tempurpedic in the early 1990s, and is still the main selling feature of most high-end mattresses today.

Memory foam is also the most expensive part of a mattress which is why many companies use less of it, instead using layers of latex, conventional foam, or fluffy covers. They claim this is for “better bounce” or “better cooling”, but in fact it is to reduce their manufacturing costs.
