If you're set on memory foam beds you've got two options -- buying a mattress and foundation set or buying them separately. Both could qualify for a free home trial. But is a foundation really necessary for a visco memory bed?
With regular beds, foundations do more than simply provide support. The shock-absorber effect you get from a box spring also helps extend the life of the steel springs in your bed. Because memory foam beds already absorb shock, using a foundation is not essential.
The only reason, then, to use a foundation is to get the bed some 8-9 inches up off the floor. If you do intend to use a foundation with your memory bed, however, here is what the best foundation should look like.
There are two reasons why regular box-spring foundations should not be used with visco beds and mattresses.
First of all, all foam beds are designed to easily shape to whatever's applying pressure. The custom shaping effect of Tempur beds -- or of any other brand, in fact -- means that memory beds shape to uneven surfaces even better.
A memory foam bed used with an uneven foundation becomes uneven itself. The mattress takes the foundation's shape and becomes an unhealthy sleeping surface. However good memory foam may be, an uneven bed surface does not allow your muscles to relax the way they are supposed to and you may still wake up in pain.
Second of all, visco foam mattresses and beds are designed to absorb shock and relieve pressure points.
When you lie on a regular innerspring mattress, your own body weight pulls you down. Springs react by pushing back against you. The skin and blood vessels are caught in the middle, squeezed between the gravity force of your weight and the upwards force of the mattress.
Pressure points constrict circulation at the area of contact. The result is discomfort and even pain over time. When you lie on a visco foam bed, however there is no air left in the cells to push back and cause discomfort.
Air is spread to adjoining cells and the viscoelastic bed simply 'melts' under you to provide balanced support. It is this very lack of spring-back force in memory foam beds that help relieve pressure.
If you use a box-spring foundation with the memory bed, the pressure-relieving properties of the visco foam change. The foundation's resilience ads a spring-back force where there was none previously.
The spring-back force in the foundation is transferred to the bed which then starts to push back as if had springs. This pretty much defeats the purpose of memory foam beds. You're more than likely to dislike memory foam if you try this during your home trial period.
A Critical Eye On The Latest Mattress Technologies
Which to choose from a 3.5lb visco elastic memory foam mattress topper 5.5lb visco foam matress comparison? Higher density alone does not make a quality sleeping surface. The formula behind the best sleeping surface uses best quality, high-density foam that responds to body temperature.
What is the secret behind Tempur mattress technology and why is it in the top 5 most popular brands alongside the likes of Sensus, Isotonic, Bergad and Sealy? The answer is that it uses good quality, high density, heat responsive foam.
The most commonly reported problem consumers have with memory foam mattresses is that they sleep hotter when compared to conventional sleeping surfaces.
But sleeping conditions are influenced by environment temperature, the material's heat sensitivity and your own body heat.
