How thick of a mattress should you choose?
The thickness—or in other words, the height of a mattress when placed horizontally—is an important aspect, even if this doesn’t always affect its durability or comfort. In that regard, a number of additional considerations will guide you in your choice.
Of course, you can choose one brand over another or opt for a foam mattress, spring mattress, low-priced model or luxury model, among other things. However, if your primary objective is to sleep well, the quality of the mattress and your personal perception of its comfort will take precedence.
Mattress thickness based on the user’s weight
Choosing the length or width of a mattress is a fairly simple matter. Obviously, a child (or a small-stature adult living alone) doesn’t necessarily have to choose a particularly large bed. Admittedly, most people tend to prefer either a queen- or king-size bed. Other than that, we’re already familiar with the available sizes.
However, when it comes to the thickness of a mattress, it’s a bit more complicated. Even though a number of variables come into play, considering the weight of the user isn’t a bad place to start. In the case of a foam mattress, the heavier the person is, the denser the material should be. For purposes of supporting weight, density is more important than thickness. In the case of a spring mattress, the number of springs, their quality and their resistance will make all the difference in terms of comfort and durability.
For example, a good-quality latex mattress that’s 8 to 10 inches thick could be very suitable for a heavier person. On the other hand, a poor-quality 15-inch-thick mattress will have a shorter service life.
Furthermore, for esthetic reasons or because of the design of their furniture, some people might prefer a very thick mattress or, conversely, a very thin one that works well with the height of the headboard.
Other important information
A thinner mattress with more springs per square foot will last longer and provide more support than a thicker one with fewer springs will. Although large springs will make the bed more durable, they’ll also make it “harder.” However, the presence of foam on top of the springs can offset this firmness. As for foam mattresses, they come in different densities, depending on the manufacturing process. The support they provide will vary in proportion to the pounds of material per square foot. The type of material also plays a role: polyurethane foam is firmer than natural latex, even when they’re both of the same density. Finally, a mattress must be sturdier if it doesn’t rest on top of a bed base (whether box springs, slats or otherwise).
