"Worst bed ever. First of all, it is like a rock. When you move in your sleep, it take several minutes for the bed to realign to your body so you are lying in "holes" in the foam and have nor support where you want it, and weird shapes of foam poking into you. The worst part is the odor, which we were told would go away in several days."
"VERY UPSET. This bed hurts my body SOOOOOO bad!! I can NOT sleep. It is so firm and uncomfortable!!! Its like sleeping on a wood plank and nothing like a cloud or anything comfortable. I can not fall asleep and when I wake up my body is killing me. I would NOT recommend this bed to anyone that is not at least 250 pounds."
"Too Hot! I found the mattress very cool in the store. Unfortunately, at home I discovered after laying on the mattress for more than 30 minutes it becomes unpleasantly hot."
Since Tempur-Pedic's introduction of what is commonly referred to as 'memory foam' approximately 25 years ago, memory foam has become the material of choice for most mattresses, either in combination with other materials such as innersprings, air and latex, or by itself.
Almost all foam mattresses are constructed with flat slabs of foam. The reality is that ultra-low pressures and postural alignment cannot be achieved with flat foam layer constructions. With memory foam or latex, as your hip or shoulder tries to 'sink down' to the level required for ultra-low pressure with postural alignment, flat foam layers resist stretching and compression. The further into the mattress that the hip and shoulder want and try to go, the harder the foam gets, and feels.
Since a sleeper has both varying density and body contour in the head to foot direction, the mattress firmness must vary along its length to conform to these variations in order to achieve correct postural alignment. Conventional mattresses are flat, not contoured, and can cause spinal misalignment resulting in low back pain.
It's not about a mattress being just soft, medium or firm. Ultra-low pressures between the mattress and body will eliminate the occurrence of mattress-induced sleep-disturbing movement. Excessive body pressures, if unrelieved, would eventually cause a decubitus ulcer (bed sore) to form. But with a normal sleeper, the brain signals the body to move to prevent skin damage. These movements, typically 30-60 times per night, disturb sleep significantly.
The Perfect Pressure mattress IS NOT memory foam. It features our exclusive ULTRAFOAM (Ultra Low-pressure Tensile Relief and Alignment) design, a unique combination of the highest grade foam with our exclusive, patent-pending pressure-relieving architecture. This will give you the best possible sleep, all night long.
With memory foam you effectively sleeping 'in' the foam in the 'valley' that your body creates. Sleeping 'in' the foam is what results in many restriction-of-movement complaints and 'sleeping hot' complaints cause by the retention of heat caused by your body.
Historically, sleeping 'on' conventional foam, which was not memory foam, did not provide the reduced pressure points of sleeping in memory foam. With the Perfect Pressure mattress and its unique 5 zones of firmness you can actually reduce and lower the pressure points caused by the mattress on a sleeper's shoulders and hips and the mattress without the drawbacks that are characteristic of memory foam.CLICK HERE for test results.
