Types of Memory Foam Mattresses

Memory foam mattresses can be brought at different densities measure in lbs. Whilst this might seem trivial it can have a big overall effect on the feel of the mattress when sleeping. The most popular types are the 4lb and 5lb mattresses.

5lb memory foam is heavier and more temperature sensitive. It’s usually a lot firmer and restores back to it’s natural shape more readily. A 4lb mattress has more give, being lighter and molding to your body more. Also it is less temperature sensitive. Deciding which to choose is a matter of preference some people prefer a ‘firmer’ feel where as other like softness.

If you have the money you can get the best of both world which combines both densities, Tri-Pedic make a mattress that has a 5lb bottom layer and a 4lb top layer. This gives you the initial comfort and softness of the 4lb but with the added support of the 5lb mattress. Sounds good to me!
