A memory foam mattress is derived from polyurethane and other added chemicals that eventually rise up its viscosity level, thus, resulting to increased density. A typical memory foam mattress has the special feature of getting firmer in cool environments and much softer in warm surroundings. In one point of fact, a memory foam mattress responds when the heat of body is transferred to the mattress by conforming and taking the shape of the body. However, the pace of the response varies significantly on the density of the mattress. Memory foam mattress that is made of high density materials conforms the shape of the body in a few minutes after pressure is applied into it while a low density mattress takes the shape of the body more quickly. This is actually created for the purpose of comfort attained when pressure is applied on the mattress. In return, when the pressure is taken away, the mattress will get back into its original form.
The difference between memory foam mattresses from customary spring mattresses is that spring mattresses get back to its previous form immediately when pressure is removed. When you lie down on an ordinary spring mattress, you will actually feel an equal pushing force upward against the pressure making the pressure points sore, resulting to increased pain and discomfort; therefore, your sleep will get interrupted. The quality of sleep depends on the quality of memory foam mattress that may differ on the quality of the foam used which is greatly affected by the density. So, a sleep in a quality memory foam mattress would signify a comfortable rest and a very refreshed morning the moment you wake up. Indeed, memory foam mattress can make a great significance in the comfort of the consumer.
