How To Choose Your Mattress Thickness

While understanding the categories of mattress thickness can narrow down your mattress search, identifying your unique sleep preferences and needs can help pinpoint the exact mattress of your dreams.

When choosing a mattress thickness, youll want to consider:

  • Sleep position Whether you like to sleep like a starfish atop a warm rock, or a cat curled up on its side, different sleep positions can benefit from different mattress thicknesses. Back sleepers, for instance, should look for mattresses between 6 and 8 inches to best support their shoulders and bottoms, while maintaining spinal alignment. Side sleepers need additional support for the hips, making a mattress between 8 and 10 inches the ideal choice. Stomach sleepers, who need comfort for their fronts and support for their lower backs, should look for a mattress between 10 and 15 inches thick. With that said, stomach sleeping can strain your neck and back3, making it difficult for any mattress thickness to support you properly.
  • Body weight Additional mattress thickness allows for greater amounts of weight to be evenly distributed over the mattress, which is essential for achieving spinal alignment and maximizing support. This is particularly beneficial to couples who need a mattress that can withstand the weight of two people rather than just one.

Similarly, if you have a tall bed frame, you probably want to forgo an extra thick mattress and avoid leaping into and out of your bed every day.

Why Mattress Thickness Varies

Mattress thickness varies based on whats inside the mattress. Each company has its own thickness options. In general, mattresses using the same materials are firmer when thinner because the materials are compressed. Theyre softer when thicker. Hybrid mattresses are thicker than foam mattresses because of the coils. The amount of gel or memory foam padding also plays a big role in mattress thickness. More foam or gel usually means a softer mattress.

Generally, you want the top of your mattress to be 25 inches from the floor. This way, your feet touch the floor when you sit on the side of the bed making it easier to get in and out of the bed. Since most mattresses are made of multiple materials, they have different sections that make them thicker or thinner.

The comfort layer if the top of the mattress that sits on top of the inner springs, gel or other materials. This is usually a pillow top that offers a soft feel no matter the stiffness of the layer underneath. The comfort layer is normally 2 to 3 inches thick and offer the support and cushion needed for each person to get a quality nights sleep.

The base layer is under the comfort layer and is the biggest determining factor in the mattress durability and longevity. This layer makes up at least 50 percent of the overall mattress thickness and should be around 12 inches thick.

How Much Should A Mattress Cost

It depends on how much material it has inside. Mattresses are often made of foam or springs but there are also waterbeds which consist of an air bladder filled with water to give it cushioning properties. There are more expensive materials and cheaper ones. Just buy a mattress at a price you can afford.

Companies try to make their product interesting so they come up with different ideas on how to sell it better than the other companies do. But dont let them fool you, just buy what works for you.

But dont buy a mattress that costs less than 150 $. It will be really poor-quality.

Sharing A Bed With A Partner Or Sleeping Alone

When you sharing a bed with a partner, you should take into consideration how close you like to sleep and how much space you need.

Its not as easy as just adding the thickness of two standard mattresses together! You have to consider how tall or heavy your partner is and how much they weigh compared to you, because if one person sinks significantly more into their side of the bed.

The most important thing is to make sure you both get a good nights sleep, so if your partner likes their side firm and you like yours soft, consider how each other feels when choosing the thickness for your bed.

A mattress with a high profile may feel very different from one bought for an individual bed if your partner is used to sleeping on a soft surface, it might not be the best choice because they could roll off in their sleep.

What Are The Benefits Of A Thicker Mattress

A thicker mattress does not always guarantee a higher level of comfort. However, there are some benefits to be considered regarding specific sleep needs.

Reviews from couples and heavy people indicate that they find a lot of added comfort in a thicker mattress. When additional weight is applied on a thicker mattress, it is still able to provide comfort even with the emphasized compression. Instead of the comfort layers sinking down to the base, you will still be able to lie on the top of the bed and receive the benefits of an even and comfortable surface.

Thicker mattresses are often more durable. The additional material allows them to be functional for longer as there are more wear and tear allowed before the bed starts to sag and become unusable. As mentioned above, this additional durability comes at a price but is often worth the extra cost.

Expecting mothers may also want to consider a thicker mattress. During pregnancy, especially the third trimester, mobility is severely limited in women and they usually sleep on their side. Additionally, bending at the waist to sit down on a low surface becomes increasingly difficult.

A thicker mattress for pregnancy will make it easier to get into and out of it. This is particularly true during all the late-night bathroom trips that are sure to result from the additional pressure placed on the bladder by the growing baby.
