by in memory foam mattress

The best visco elastic memory foam mattress for you need not necessarily be the most expensive one as each individual needs differ. The problem with buying memory foam mattresses for most people is because of the huge variety of choices available which makes choosing one difficult. Here are 5 points that you should be your area of focus when buying memory foam mattress.

Density:

This is an important aspect you need to look into before making your choice. The density of a visco elastic memory foam mattress determines its durability. Note that density is measured for memory foams in the units of pounds/cubic feet. In other words any density measurement must be given in lbs.

Response time:

Recommended density for visco elastic memory foam mattress is between 4-5lbs in density. Opting for densities higher than the recommended range may result in the foam being too slow to respond. Going lower than the recommended density may result in the foam being unable to give adequate support and wear out fast.

Indentation Force Deflection (IFD):

Without going into the technical aspects, an IFD rating is an indicator of the firmness or softness of memory foams. IFD is a very useful at gauging accurately the feel of a mattress. Individual preference on the firmness differs widely therefore no recommendation can be given however. Do note that addition of different memory foam toppers/pads can greatly change the effective IFD of a memory foam mattress.

Topper Thickness:

Visco elastic memory foams mattresses come with a base support layer forming the bottom with a combination (in most cases) with memory foam toppers of various thickness and densities to give a variety of feel to the bed. A bed made completely of memory foam is neither comfortable nor practical. Recommended thickness of the topper is between 2-3 inches. This range provides the best in support, response and durability.

Cover:

Always get good quality covers for your visco elastic memory foam mattress covers. A good cover should be waterproof, dust mite proof all the while allow for breathability. The cover should also be soft and absorbent enough to soak up body fluids including saliva.

Overall if you are above average weight always go for the higher limits of the recommended range when shopping for visco elastic memory foam mattresses.

The most common cause for bad memory foam mattress reviews arise from the fact that customers are unable to figure out the basic guidelines they need to understand while buying memory foam mattresses. There are a large variety of memory foam mattresses in terms of thickness, density, IFD (Indentation Force Deflection), cell spacing (temperature sensitivity) etc, which are configured to suit various needs.
