How Different Types of Mattresses Compare for 400-Pound Person

The main types of mattresses are innerspring, memory foam, latex, and hybrids. Each kind has certain benefits and drawbacks for larger people. Let’s delve into these details:

Memory Foam

Memory foam is one of the most attractive choices for heavier sleepers. This is because they offer the highest level of support and durability.

Since a majority of them are constructed from high-density foam, they’re less likely to give in under heavy weight.

The distinct characteristic of innerspring mattresses are the coils that compress once an individual lies on the mattress.

Unfortunately, these mattresses offer less support compared to memory foam.

On the plus side, they sleep cooler and are much easier to get on and off from compared to foam mattresses.


Latex combines the best attributes of memory foam and innerspring mattresses.

That is, they offer excellent support, are firm and keep you cool. So if you want the best of both worlds, latex mattresses are the way to go.

Moreover, it’s easier to get off or onto a latex mattress.

Also, this mattress is known to retain its shape over time. This is an important aspect for heavy people who are likely to leave deep depressions on their mattresses as time goes by.


hybrid mattress

As the name suggests, this is a mattress that combines two or more elements of the previous types. For instance, you might come across a mattress that has an innerspring core and a memory foam layer.

Using different layers is advantageous in that it optimizes admirable features like comfort and support while minimizing unpleasant features like sleeping hot.

This explains why hybrid mattresses are common among heavy people.

What to Look For When Buying a Mattress for 400 Pound Person

Mattress Dimensions

The size of your mattress oftentimes determines the quality of sleep you get. That said, the right mattress for those who sleep alone is a Full or Queen size mattress.

If you sleep with a partner, you should get a King size mattress so that you’ll have enough space to yourself, but only if you have enough room.

Another parameter you’ll want to consider is the mattress thickness. Being on the heavier side of the scale means that you’ll push the mattress down fairly quickly.

If you purchase a thin mattress, you will end up compressing it to the point you start feeling the bed’s foundation. Here are a couple of recommendations for mattress thickness:

Weight Range (lbs)Mattress Thickness (Inches)
200 to 250Above 10
250 to 300Above 12
More than 300Above 14

Maximum Weight Recommendations

All too often, buyers consider the size, comfort, budget and material when buying a mattress.

The one aspect they forget to check is the recommended weight limit. You should always check the recommended weight limit and match it to your own.

If you’ll be sharing the mattress with someone else, then account for your combined weight.

Even if you don’t weigh 400 pounds, your combined weight might exceed this value.


mattress support

The way a mattress feels when you lie on it is what people refer to as firmness. There are two popular kinds of mattresses: ones that are very firm and others that have medium firmness.

Firm mattresses offer a great deal of resistance when compressed.

On the other hand, medium firmness means the mattress offers little resistance; hence allowing your body to sink down.

When purchasing a mattress for a 400-pound person, the ideal mattress is one that is very firm. Such a mattress is more comfortable to lie on and it provides excellent pressure relief.

This is an important aspect for heavy sleepers who lie on their sides or stomachs.

Because of their sleeping positions, their weight is distributed unevenly, making them more prone to uncomfortable pressure points at their shoulders, neck, lower back and hips.

Often, manufacturers rate the level of a mattress firmness from 1 to 10. 1 represents the least firm mattress while 10 represents the most firm.

If you weigh 300 pounds or more, you’ll want to go for mattresses rated 6 to 8. If you still feel uncomfortable, then consider choosing firmer ones.

Foam Density

If you’ve been shopping for a mattress that has foam layers- which a majority of mattresses have today- one factor you should pay attention to is the density of that foam.

To put this simply; the density is what determines how much load a particular mattress can accommodate. It also determines the durability of the mattress.

The unit of measurement for foam density is pounds per cubic foot (PCF). As an example, polyfoam described as having 1.5 to 3.5 PCF means that it has high density. As for memory foam, high density is one that rated above 6 PCF.

Unfortunately, not every manufacturer includes PCF in their mattress specifications. If the PCF is not shown on the label, you can contact the manufacturer and ask about it.

Edge Support

Edge support refers to the encasement around the mattress frame. This is not a factor that most buyers take into account. However, for heavy users who tend to sleep on the edge of their mattress, this should be a top priority.

The best types of mattresses that offer edge support are innerspring and hybrid.

These are well-reinforced around the perimeter. Conversely, foam and latex mattresses are often not reinforced, and subsequently, offer minimal edge support.

Temperature Control

Heavier individuals are the most susceptible to excessive sweating at night. Due to their higher body mass, they generate more heat.

If you often this problem, then one factor you should consider when buying a new mattress is its temperature regulation capabilities.

More specifically, we recommend going for innerspring and hybrid mattresses as they allow greater airflow; thus, retain very little heat.

You will want to avoid some types of foam mattresses as they retain most heat. The only exception is mattresses made of gel or latex foam, as these ones are designed to keep you cool throughout the night.

Final Verdict

Now that you have all the right information, you will find it very easy to pick a mattress for a 400-pound person. Generally, the heavier you are, the firmer and denser the mattress you need.

This is to ensure that you get the right amount of support when you sleep. Besides, a firm mattress will be able to hold your weight for a long time without sagging.

Apart from firmness, also check the dimensions and temperature regulation capabilities of the mattress.
