Is The Memory Foam Mattress The New King Of Comfort?
The memory foam mattress is probably one of the most comfortable mattresses on the market today. However, if you do want to buy a quality foam mattress, you will find that they may be pricey in terms of dollars spent. However, when you consider the value of your improved sleeping comfort, it then becomes money well spent.
Also, you should be aware that not all foam mattresses are equal. Like everything else out there, you have to pay attention to the details... the trick is to have your foam mattress support and contour to your body, but not to envelope you.
This is a similarity to the innerspring mattress: you can pick one that is too soft or too hard. If it is too soft, you will sink into it and “bottom out”. In other words, it will not offer enough support, and you will feel the sub frame material underneath.
When the foam is too hard, it won't contour to your body until your body heat warms it up. Then it will mold around you. The challenge here is that after you have settled in, it makes it hard to roll over or change positions. It kind of feels like you are in a cast or mold.
A memory foam mattress can be graded on several parameters; however, I am only going to talk about three of them: - First, it has to be viscoelastic.
- Meaning it is temperature sensitive and will always return to its original shape. It should do this quickly.
- Second, it is measured in density pounds per square foot.
- This is called the "weight" and is, in part, determined by the proportion and quality of the foam and chemicals used in the composition of the end product.
- You will see a range of foam weight from between 2-3 lb to 4-5 lb densities.
- Third, the ILD (Indentation Load Deflection).
- This is determined by the hardness or stiffness of the mattress.
Remember: the higher the ILD number, the firmer the foam will be.
This is just an indicator to help figure out what is most comfortable for you. If you try out a bed and it seems too hard, see what the ILD number is and find a bed with a lower number to see if it works better for you.
So what is the big deal about viscoelastic foam? Bottom line, it works!
There isn't any other foam material that distributes pressure as evenly as memory foam.
People using this type of foam simply sleep better, have less pain, and have a tendency to toss and turn less during the night. They just get a better night's sleep.
As a note:
Some people can confuse memory foam with latex. Latex is used to create foam-bedding material and there is a market for the product.
For example: It can be used for the core of a mattress, but not the top layer. It has a higher elasticity and more resilience than the viscoelastic memory foam.
Latex has a tendency to feel springy, so it feels like it is pushing against you.
