Most memory foam mattress reviews will only select 2 or 3 mattresses and do a side-by-side comparison to show you which of them is the best.
Now the problem with that approach is that they readily pick the 3 mattresses they are going to compare.
This means you won't even have the chance to know what the other hundreds of mattresses might have to offer.
In this short review, I'm going to give you the basics of what truly makes a good memory foam mattress and then let you decide.
I do have a recommendation in the left navigation bar of this page but you will be able to judge the merits of any mattress with what I'm about to reveal to you.
You can go through hundreds of webpages looking at every memory foam mattress that's ever been made and you'll come up with a ton of confusion and misinformation.
You can come up with the same results if you try to read all the memory foam mattress reviews that have ever been written.
The fact is that there are only a few things you need to know about a memory foam mattress in order to make a selection that will absolutely delight you.
4 Critical Things You Must Know:
Country of Origin
Country of Origin
First and most critical is the country in which the foam is poured. No matter what I reveal to you here, none of it will matter if you begin with a foreign foam that contains harmful chemicals that wouldn't be allowed to be put into American-made foams.
Foreign foam has given memory foam mattresses some bad reputation because they might smell funny or not be as comfortable as the ones made in America using American labor and foam.
Density of Foam
Next, the density of the memory foam is what makes it suitable for properly supporting your body to deliver sweet, pain-free sleep.
Density is a measurement of the weight of the foam and 5 lb. density or greater is considered to be the most supportive.
4 lb. density foam is acceptable but won't give the same support and won't last as long as the denser foam so it should be priced accordingly.
You can buy a 4 lb. mattress for much less than a denser 5 lb. mattress so if you get one, put it on your bed and see how you like sleeping on memory foam.
If you like it, give the mattress to one of your kids or put it into a guest room and buy yourself a higher-density mattress.
Not all manufacturers and dealers will be honest in their dealings so you must ask if the memory foam they're trying to sell you is temperature-sensitive.
Memory foam doesn't have a strict definition so someone could be passing non-sensitive foam off as memory foam.
Temperature-sensitive foam will soften under your body as heat is transferred into the foam making it even more comfortable.
ILD is a technical way of rating the firmness of a mattress.
If you like a firm mattress, you'll want an ILD of 16 or more while a very soft mattress might have an ILD of 10 to 11.
Trying different firmnesses and then asking what the ILD is will help you in determining which mattress might best suit your needs.
Also, many of the mattresses are made up with two or more layers of memory foam to give you a soft feel on top and the supportive feel under that.
Like I said in the beginning, not all memory foam mattress reviews give you information like this but I feel it helps for you to be informed about the basics.
