Although, memory foam mattresses are the most popular in the market, you shouldn't buy any that you come across. This is because you can end up wasting a lot of money by buying a substandard product. To be on the safe side you should put the following considerations in place:
A good mattress should be able to support your body properly. The good side is that you can easily find the density by taking a look at the package and from the package you will know whether the unit is of cheap, min-grade or good density.
Cheap foam has a density of 2-3 lb, mid-grade has a 3-4 lb density, while a good form has a density of over 4.5 lb. According to experts, the foam that supports the body maximally is one that has a density of between 5.3 and 6.2 lbs.
This is another important factor that you should consider. The good side is that you can easily determine whether the unit will be durable or not by simply looking at it. For the unit to be durable, it should contain medium or high-density foam. As rule of thumb it should not contain layers of cheap materials.
Since the mattress tends to be expensive, you should consider the warranty issue. To be on the safe side, you should buy from a company that offers a long warranty.
While it's advised that you go for a company offering a warranty, you should avoid buying from a company that has been in business for a short period of time. To be sure that the unit you are buying is of good quality you should buy it from a company that has been in operation for over five years.
Different companies sell the units at different prices; therefore, you should take upon yourself to compare the different prices. One of the best places to compare the prices is online. You should visit online stores and compare their prices.
Comfort test period
Although, there is a lot of hype about memory foam mattresses, it doesn't mean that you will like them. For you to be able to return the unit if you are dissatisfied with it, you should buy from a company offering a comfort test period.
Before you make the decision on whether to return the unit it's wise that you allow yourself time to adjust to the new mattress.
