It's hard to resist an attractively priced visco mattress but before you give in to the temptation, let me explain how expensive Tempurpedic knockoffs really are in the long run (read what makes the best memory foams first).
Cheaper memory foam mattresses are made of low density viscoelastic foam which has bigger but fewer open cells. The air is spread to adjoining cells much quicker so you sink in faster. This may feel nice and soft to begin with but the mattress or bed doesn't have as much body to provide proper cushion. In other words, you keep sinking in until you bottom out.
Good quality mattresses like Tempurpedic and other leading brands (see Ergoflex), however, let you sink in but not that much that it's a chore rolling over. They let you sink in only where softened by body heat while the rest keeps you well cushioned.
Getting stuck in a hole in the middle of the mattress makes rolling over that much more difficult, to the point where it interrupts your deep, restful sleep. The cost? Over time you actually feel more tired as opposed to fully rested in the morning.
Lower density visco elastic memory foam also wears out much quicker and in time, it stops regaining its original shape. Less dense cell structures crumble quicker than closely knit cells that support each other for a longer period of time. Cheap, low density memory mattresses can show sagging in the middle in as early as 10 months.
Sagging mattresss keep your spine out of alignment during the whole night. It takes years before high quality Tempur-style mattresses starts to sag. The cost? You may feel pain in the morning as a result of constricted circulation.
While there have been incidents where customers had problems returning brand-name viscoelastic mattresses under warranty, the vast majority are well covered.
Few, if any, knock offs of Tempur-Pedic Swedish mattresses come with a solid warranty that you can rely on. If something should happen to the mattress you are probably stuck with it. The cost? The price of a new mattress you'd have to buy and the lack of restful sleep for as long as you continue sleeping on the old one.
While the initial cost of inexpensive mattresses is attractive, you'll find that they last for up to 8 years less than a good quality mattress does. You may find that in the space of 10 years you actually spend more on replacing discount mattresses than you would have spent buying a good bed in the first place.
The cost is not only reflected in the extra dollars you spend but also in the lost hours of restful sleep and frustration.
If you simply cannot afford a good quality, high density, temperature-sensitive memory foam mattress like Tempur-Pedic, then you're better off buying a non-memory foam, but nonetheless, good quality, mattress.

A Critical Eye On The Latest Mattress Technologies
What affects the expected lifetime of a visco foam bed and does a Tempur bed last longer? The answer is years and years as long as it's made of better quality, higher-density foam.
Many manufacturers claim visco memory foam was first used by the NASA Space Program to boost sales for their foam pillows.
NASA never did use that basic material in the 1960s. NASA mattresses or space mattresses simply do not exist as such.
The truth is the Swedish Tempurpedic company did eventually come up with a reliable formula now used in the best-selling Tempur-Pedic bed.
While Tempurpedic toppers are commonly known as Swedish toppers, not all such products made in Sweden are made of the so-called NASA foam.
How can you check if your purchase as good as a true Tempurpedic bed? You can try the wine glass test, the egg test, or the fridge test.
