Before you rush to buy a memory foam mattress, there are a few things that you should consider. First of all you should assess whether you need a full -on memory foam mattress or a mattress top would meet with your requirements and budget. People are generally unaware that memory foam mattresses have different densities and sizes. Likewise, there are temperature considerations to be taken into account. You should be aware that a pad could give a new look to your old worn out mattress. But, let’s first understand the difference between a full-on mattress and a topper and the difference of densities and sizes.
A mattress is completely made from memory foam while a topper has layers of foam that may be used on top of your present mattress. It’s therefore understandable that a full mattress would cost more than a toper. The toppers come in many sizes, though size of two to four inches is most often used. A topper of two or three inches would generally suffice an average person but the heavier ones may feel more comfortable with a four inch topper as it provides extra support. The density range varies from two pounds to eight pounds with price being in direct proportion to density. S density of five pounds is good enough and lasts for a long time. Another parameter employed to define hardness or softness of mattresses is called ILD. The higher the ILD, the tougher the mattress, meaning that an ILD of 20 makes a mattress very hard whole an ILD of 8 denotes that it’s a soft mattress. You should keep that in mind at the time of purchase. Further, memory foam mattresses are temperature sensitive too.
The temperature sensitivity of mattress may demand slight adjustment on your part, depending on temperature that keeps you comfortable while in bed. If you lie to keep your room chilled at night, you should ideally heat up your mattress with an electrical blanket before sleeping. As memory foam mattresses are known to retain heat, manufacturers recommend trying it with or without a sheet over it. That changes the temperature significantly and you have to decide what makes you more comfortable.
