When you set out to buy a memory foam mattress, you should have a thorough knowledge about the product itself. These mattresses cost money and you should arm yourself with information to make sure that you are getting your money’s worth.

Memory Foam- An Introduction

Memory foam is obtained when artificial fibers called polyurethane are treated with chemicals. The chemicals increase the weight and density of the foam. Different combinations bring about variations in the density and texture of the foam. The foam’s grading gives you further details. Memory foam possesses the quality of moulding to fit body contours. This molding makes the memory foam an excellent orthopedic support. The foam is temperature sensitive and becomes softer at higher temperatures. The foam also rebounds to normal quickly.

There are a number of methods to grade foam. One method of grading foam is by checking its density. Most brands have foam of 4 pounds density. The lower limit in most cases is 2 pounds. You can understand how soft or firm the mattress is by checking its Indentation Load Deflection rating. A higher Indentation Load Deflection ratingm eans that the mattress is firm.

Some manufaturers also specify the foam’s resilience. This checks the springiness of the foam. The abbreviation H.R shows that the foam is highly resilient and is hence more durable when it comes to withstanding compression forces. You can also check the tensile strength of the foam. This indicates the stretchiness of the foam. This is of less importance.

Handy Tips

You may notice a strange smell coming from the foam when you get it home. The smell could last up to two weeks. Those who are sensitive may find the smell disconcerting. You can get rid of this by airing the room and washing sheets frequently. An ozonator also helps get rid of the smell.

A good memory foam mattress does not need a box spring support. Most branded manufacturers place a sturdy sheath of  polyurethane to give support to the upper layers. If you want to increase the bed’s height you can place it on an even platform base. Check mattress indentation by sitting and standing all over it.
