Tempur-Pedic was the first to employ viscoelastic material in the manufacture of its mattresses and still remain the market leader in memory foam mattresses. Many other companies now make memory foam mattresses like the Simmons ComforPedic Mattress and the Sealy TrueForm Mattress. But why have memory foam mattresses proved such a success? The answer lies in the indisputable benefits of memory foam.

Temperature and Weight Sensitive

All memory foam mattresses like the Tempur-Pedic mattress are sensitive to weight and body heat: the higher the body temperature the more soft memory foam mattresses become; the cooler the body, the firmer the mattress. Most people enjoy this sensation. More importantly, the mattress changes shape to match the exact contours of your body, giving better support and correct spine alignment. Many orthopedic expects concur that memory foam (like the Tempur-Pedic mattress) delivers the best, orthopedically correct alignment of your neck and spine. Testing by the Institution for Clinical & Physiological Research at the Lillhagen Hospital in Gothenburg, Sweden of 23,000 patients for a period corresponding to approximately 8 years of clinical and in-home use concluded that the patients suffered from less pain and experienced greatly enhanced and deeper sleep when they slept on a memory foam mattress.

Suitable for all Weights

Unlike conventional spring mattresses, the Tempur-Pedic mattress is suitable for all weights; you don't need to buy a firmer mattress for someone heavy and a softer mattress for someone who is lighter. This is great news for couples where one was substantially heavier than the other; there's no longer any need to buy a twin mattress when you buy a Tempur-Pedic mattress (or any other memory foam mattress).

True Motion Separation

The problem with conventional, inner-spring mattresses was that, because all the springs are inter-connected, when one partner moved, the other partner's sleep would be disturbed. The Tempur-Pedic mattress is made entirely from high-density foam and memory foam. The result is that there is true motion separation; the tossing and turning of a partner does not ?ripple over? to the other.

No Need to Turn the Mattress

Most traditional, top rated mattresses need to be turned every 3 months; this can be a somewhat arduous task as many quality mattresses are fairly heavy. A real benefit of a memory foam mattress is that you never need turn the mattress; just put it on top of the bed and forget about it.

The Warranty

Tempur-Pedic mattresses all come with an excellent warranty (a 10 year limited warranty) that can match that of any other manufacturer of memory foam mattresses ? the terry-cloth mattress cover is warranted for two (2) years against faults in material or workmanship.

A good quality mattress is a hefty financial investment and the Tempur-Pedic mattress is probably the most expensive memory foam mattress on the market. Despite the cost factor, the Tempur-Pedic memory foam mattress remains the most popular on the market. I know that marketing can artificially increase a company's market share but Tempur-Pedic has been in the market long enough now that the novelty value and shrewd marketing pitch doesn't fool the consumer: the reason the Tempur-Pedic mattress is the most popular brand of memory foam mattress is because of the genuine sleep benefits that most people have experienced with it.
