Memory Foam: Memory Foam Mattress
built 607 days ago
A dense Memory Foam mattress reacts with body heat and consequently within a few minutes the product forms around the shape of the body. There are 3 postures in which human's sleep- back, stomach and side. The people use more than one position to sleep. The firm mattresses are recommended for people sleeping on back and stomach, as soft mattresses might harm their backs due to unnatural angles. Those sleeping on sides, softer mattresses are suggested.

The Memory Foam Mattress molds to all the contours of your body, giving your neck, shoulders, back, & feet the proper support. Because of this, pressure is evenly distributed, preventing pressure points and allowing proper support; allowing a much better blood circulation through out the body. All this equates to less tossing & turning, and allowing your body to rest & sleep more soundly.

Memory Foam is a compliant type of material with a cellular structure that is completely different than normal foam. It is made up of billions of high density viscoelastic memory cells. The cells are spherical with windows that are temperature sensitive. When you come in contact with the memory foam mattress, it reacts with your body heat, softens and gently conforms to your shape. Pressure Points are removed from your entire body, as the mattress forms an incredibly comfortable yet firm and supportive cushion for sound restful sleep. It is like having a mattress custom designed to fit your body.

Memory foam was originally developed by NASA to decrease the very high pressure caused by the extreme g-force occurring during the take-off of the space shuttle. It was never used in the space program but was subsequently used medically, for example by patients who used to lie in bed on hard or very firm mattresses for long periods of time without regularly moving such as being bed-bound after a paralyzing stroke. The pressure over some of their bony regions decreased or stopped the blood flow to the region causing horrific pressure sores and/or gangrene. Memory foam mattresses helped hugely to decrease such events.

Memory foam is made of an oil-based polyurethane foam comprised of billions of tiny air-filled cells. When you lie down on the memory foam, the cells compress with the air in each cell moving slowly from cell to cell allowing some to fully compress while others expand. The foam takes your shape but still has enough material integrity to support your weight comfortably. Memory foam can be made of different densities for different levels of support. The differences in these levels of density will be important for selecting the mattress that is best for you.

As long as your existing mattress is in good condition, a Memory Foam topper could certainly provide the extra comfort you need. The nature of memory foam is to conform to the surface it’s set on though, so make sure you don’t have any valleys and depressions in your mattress. To get the most out of your topper, make sure you purchase one with a density of 5 lb. or higher. Anything less will feel sub par and break down quickly. A warranty of 2-5 years is average on most toppers.
