How Thick Should My Mattress Be?

How Thick Should My Mattress BeThis is mostly down to personal choice, but there are some small factors that come into play when deciding how thick your particular memory foam mattress should be. The easiest thing to point out is that thicker foam means more money you will have to spend, so watch out depending on who you buy from. Choosing a memory foam mattress that is too thin, like say below 10 inches, can really destroy the experience and flush money down the drain. It goes without saying that the thicker the foam, the more comfortable the user will be. The most important part about the thickness is the base support on the bottom, and the top layer which acts as the first contact. If these two layers are good and thick, then buyers will be okay. A great support base makes all the difference in the world but will be useless if the top layer is substandard, and if the top layer is a nice 3 inch gel memory foam then it will also be worthless if the support base is weak. Memory foam layers work together to give as a team, so when looking at thickness look at what all the layers have to provide.


How Thick Should My Mattress BeA memory foam mattress can contain as many as 5 layers total, and as little as 2 layers. Typically modern memory foam has at least 3 layers, with the premium brands having 4 or more. The two most important layers are the base layer which provides support, and the top layer that has the premium memory foam that controls the entire experience. Everything else is secondary to these two things, so you want both the base layer and the top layer to be where the majority of the memory foam is going. If you run across any deal that has a small amount dedicated to the base layer then chances are it won’t support you well enough and will give a substandard experience, regardless of the other layers.

A perfect base layer will be 50% or more of a mattresses, so a 12 inch memory foam mattress will have at least 6 inches dedicated to the base foam. That’s food for thought that a 12 inch thick mattress can become useless if the base support layer dips below 50%, even with other quality materials. But that is not the only area where consumers need to look! The top layer needs to be at least 2 inches, regardless of the thickness of the memory foam. So even in the bare minimum that a consumer should look for in a memory foam mattress of 10 inches, at least 5 inches of that should be the base support foam and at least 2 inches of that should be the top layer-everything else once again is secondary, whether it is the airflow layer, or a comfort layer. Pay close attention to the layers when looking at thickness in a memory foam mattress, it will save you a lot of money down the road.


How Thick Should My Mattress BeWhile some consumers don’t have a height requirement, others do that may make it difficult for them to get out of bed. The thickness of a memory foam mattress comes into play with an extra inch or 2 could mean the difference between getting out of bed comfortably and getting in bed comfortably. It can become a hassle that can really ruin the sleeping experience, and in some cases can even lead to injury. With everyone having different frames and bed setups there are instances where consumers are higher off the ground than they would like to be, where a few inches can make all the difference in the world. The same rule from the previous section still applies, even if you are looking for a less thick memory foam mattress.

The minimum thickness should always be 10, so any lower than that and it is wasted money down the drain. If by chance you purchase a memory foam mattress that is a little bigger than expected, then there are frame sets that can be purchased. This is idea right out of the box if for consumers that have their memory foam placed on a spring set, which isn’t the correct way to have it. Always put it on a steady surface with full support to receive the maximum benefits. The combination of the memory foam and the frame set may remove a few extra inches and make getting in and out of bed more comfortable, even with the thick mattress.

Body Type

How Thick Should My Mattress BeAnother reason to prefer a thicker memory foam mattress is based on body type, as the rule goes the heavier the body, the thicker you want the memory foam to be. Although memory foam will do a generally good job of contouring to your particular body, there are limits, and those limits are met if the thickness of the memory foam can’t accommodate the bodies on the bed. There is no added benefit with going with a smaller thickness other than the height is less, so whenever in doubt always go for the thicker memory foam option. Even if it costs a little more, it will be one less headache in the future when you’re dealing with the mattress. Buyers that are above 6ft. should always consider a thickness of at least 12 minimum for maximum comfort levels.


The pricing is going to be a tricky figure, but usually falls under the umbrella of if it is thicker then it will cost more money. In many cases buyers can purchase a 12 inch for the same price as a 14 inch memory foam, without losing any of the features. It just takes a little shopping around and catching sales at the right moment. Buyers may also notice that a 12 inch option is only a couple of dollars cheaper than the next size up, so why not take the plunge? Memory foam thickness is a good thing, so go ahead and indulge if it is only a little bit more money.


This was just a small guide on how to really gauge what thickness to look for in a memory foam mattress. There may be some confusion concerning some things, but this should clear them up right away. With the price of memory foam trending down, buyers should definitely look into getting memory foam that is 10+ inches thick since the price is a lot better than it was a few years ago. The market is hungry for new ideas, and as the prices of the materials fluctuate buyers shouldn’t be surprised to see the inches being offered rise, at which point they should take full advantage of it. Sadly these new thick memory foam mattresses may only be provided by the bigger mattress brands in the beginning. But as time has shown it won’t be long before the smaller brands pick up the slack and start offering the newer thicker size to the public at a discounted rate. And if the public is lucky, it may be the smaller brand that innovates and offers a thicker memory foam mattress to begin with. One could only hope, as it would really turn the industry on its head.
