Memory foam mattresses are made from visco-elastic PU foam made with millions of cells that are sphere shaped. It has the ability to contour to the shape of the body for maximum support. A memory foam is different from a standard mattress because it allows air to pass through freely to prevent excess sweating while keeping the user cool.
The mattress has gained popularity across Europe and preferred by health institutions and authorities since it aids a patient’s body. It discourages pressure points from becoming uncomfortable for a bedridden patient.
Since people started realizing the benefits of memory foam, there has been a huge demand for the product. With this also comes more sellers, and lots of difference in standards and quality. This is why you must look out for some factors before you buy beds online.
The basic things to look out for are the ILD rating, firmness rating, and density. Here are other things to look out for:
Size of the mattress
Most human beings spend a third of their life in bed. You obviously want to have a good night rest at night. You should make sure that the size of the mattress is big enough to accommodate your weight and width.
Make sure your bedstead can accommodate the mattress
Some beds help the memory mattress to perform better. Ensure that the slates are between 2 to 3 inches apart and not more. Most memory foams can be used well with divan or box type of bed.
The depth of a mattress is very important because this will determine how effective it will be in relieving pressure points, and provide you with a good night rest while supporting your body.
Getting to know what the density of memory foam means
When measuring the density, what is checked is the top layer of the visco-elastic memory and not the fullness of the mattress. Memory foam with good support is one with high resilience polyurethane foam or impact resistant. If the density has a lower rating, it means that low raw material has been used in the foam. It also means that it has more air cells or cavities. Foams with a higher density rating of visco-elastic provide more support.
A good quality mattress will feel full-bodied and sumptuous while those with lower density will not feel the same. But some manufacturers have a way of deceiving consumers into thinking that the mattress has good quality when it is not so. To be safe, go for companies that offer guarantees or at least long warranties of not less than 12 months.
How will firm memory foam really feel? Start by checking out the manufacturer’s rating and the words they use such as a soft, medium and firm mattress.
The combination of a mattress’ density and Indentation Load Deflection (ILD) is what will help you know the quality and firmness of such mattress. The mattress needs to indent by 25% with ILD rating of between 10 and 12.
