Best Memory Foam Mattress
Make the Right Choice
Sleeping is very essential and critical which takes up around one third of your lifetime. You need to sleep tight and peacefully so that you can really wake up fit and fresh in the morning ready to take on what the day has in store for you. To really get a sound sleep, your mattress is very critical. There are many reasons why choosing the best-suited mattress is very essential. Firstly, it should be very comfortable so that you can sleep well. It should be able to support your body – each and every part of it – so that you don’t wake up with a painful body part, where you should have got rid of any stress or pain your body was already feeling. In case of existing physical ailments, such as back pain or any other bone or muscle ailment, choice of a good mattress becomes even more important.
Here is a quick reference guide to choose the best memory foam mattress that is suited for you. We will be discussing a particular type of mattress that is memory foam mattress. Memory foam is a special variety of foam that is generally more dense and firm than other varieties of foam. It responds to temperature, hence it is firm in cold temperatures but becomes soft and deforms when subject to higher temperature. Therefore, when memory foam mattress comes in contact with a human body, it softens and reshapes itself due to body heat. It is relatively firm and tends to retain its shape, therefore is very comfortable and effective for sleeping. There are various grades of memory foam mattresses available depending upon the compositions and process of manufacturing. Mainly the viscoelastic properties and durability of the mattresses are graded.
The major parameters of determining the grade of the best memory foam mattress are:
Weight:
The weight of foam is determined as the density of foam in pounds per square foot. The weight of foam depends on the quality of foam and type and mount of chemicals utilized in manufacturing the foam. However, weight/density is not a measure of the hardness of the foam. So, higher density foam will not be harder or firmer. The density specifications of memory foam mattresses vary from lowest values of 2-3lb to highest values of 4-5lb.
ILD (Indentation Load Deflection) Rating:
The ILD rating is the actual measure of firmness of the foam being used in the memory foam mattress. The higher the ILD rating is, the more firm or hard the foam will be. As a definition, an ILD rating gives the number of pounds required to compress a 4” sample of foam by a given percentage using 50 square inch indentation. An important point to note is that even for given foam sample, the ILD rating can vary due to chemical reactions taking place with temperature variations. The ideal values of ILD ratings will depend upon personal requirements of how soft or hard mattress you require.
Resilience:
Resilience is a measure for rebounding or spring-like quality of the foam. It will tell how well the foam can rebound a ball dropped on the sample from a given height. It generally gives an idea of the durability of the foam and its quality to survive the forces of compression. So extra resilient foam will be more durable and will survive for longer usage terms.
Tensile Strength:
The tensile strength of a foam sample will tell you how much the foam can be stretched before it breaks. It may not be a very relevant quality to assess for a mattress as mattress will never be stretched, though, it may be used to compare foam samples for reliability and robustness.
These parameters can provide you a quick assessment of various grades of memory foam mattresses available with vendors and will help you in choosing the best memory foam mattress for yourself and your family.
