Are memory foam mattresses good for large people?

Last Updated on February 22, 2022

When you find yourself on the heavier side of the spectrum, you might worry that a memory foam mattress won’t support your weight adequately.

We understand that when you’re a plus-size, you won’t have as many options as someone under 15 stone, but that doesn’t mean you should feel left out. However, if you are a larger individual, you want to make sure the mattress you get can properly support your weight while promoting proper spinal alignment.

That’s where a question such as ‘Are memory foam mattresses good for a large person?’ will start to occur. If you want to learn more on the subject, continue reading.

Are memory foam mattresses good for a large or overweight person?

Are memory foam mattresses good for a large person?

Yes, memory foam mattresses are good for heavy people because of the contouring and pressure relief they offer. However, it would be best if you chose one that’s on the firmer side, so it can support your body, conforming without sagging too much.

If you are a larger person or you are looking to buy a memory foam bed for a heavier individual, you should be aware that not all types of memory foam are the same. To ensure that your choice will be supportive enough, you should look for an option created from high-density foam, as they usually are more durable and long-lasting.

For example, a memory foam bed that provides medium tension and support won’t provide the support and comfort a heavy person is looking for. Generally speaking, this type of mattress is often constructed using different layers of foam, so by making sure you purchase a high-density product that provides firm support, you ensure a good night’s rest for you and your partner (if you have one).

How does your weight affect your mattress choice?

Weight has a significant role to play when choosing a new mattress for heavier people. The more you weigh, the higher the pressure you exert. That means the higher the pressure, the better support you need.

This is why it’s crucial to find a bed with strong structural support. If you don’t, the chances you feel uncomfortable, your sleep is disrupted, and you wake up with body aches and pains are pretty high.

Unfortunately, the market is flooded with memory foam mattresses that accommodate individuals that weigh 200 pounds or less. You can even see what we consider some of the best mattresses for heavy people in the UK.

Anyone who weighs more will have fewer options when choosing a bed, but that doesn’t mean they won’t have options to pick from. Although they might be more limited, some mattress manufacturers consider heavier people and the weight limit they mark as recommended per person.

So, when you are purchasing a memory mattress for a larger individual, you should look for the following:

How does your weight affect your mattress choice?


The first factor to take into consideration is responsiveness which basically means how bouncy your mattress will be. When a bed is non-responsive, you might end up feeling stuck, and if you are heavier, the more pressure you exert on a mattress, the deeper you will sink into it.

Generally speaking, memory foam mattresses are known to mould the body, following your weight and body heat. Normally, they will distribute your body weight which makes them incredibly comfortable, but it could also make them uncomfortable for heavier sleepers.

For example, if you sink in too deep, you are likely to feel uncomfortable and stuck, which won’t help you get a good night’s sleep. That’s why you are better off with a responsive option that allows for ease of movement and keeps you comfortable through the night.


Every memory foam mattress should allow for the right amount of contouring in order to reduce pressure around your shoulders, spine, and hips without sagging excessively.

However, if you don’t have enough support for your body weight, you might end up tossing and turning in bed all night. 

Unfortunately, most mattresses aren’t built with heavier people in mind, which is why they tend to have that sinking feeling and often sag. Heavier sleepyheads typically carry the most weight around the hips and core area, which makes it crucial to have enough surface support.

Sleeping position

Your sleeping position is one of the most important factors when choosing a new mattress. That’s because your sleep position has a tremendous impact on how will you distribute your weight on the mattress itself.

For example, back sleepers spines need more support, which is why a firm option will work best. Plus, it will prevent their shoulders and hips from sinking in, keeping them comfortable all night long. 

On the other hand, side sleepers will most likely need a medium-firm choice that will relieve pressure off their shoulders and hips while offering enough support to the spine and joints.

Finally, stomach sleepers will also do well with a firm bed because they must keep their hips and shoulders levelled to prevent the lower back’s curvature.

Bottom line

Memory foam is one of the best types of mattresses for heavy individuals. They can be hard or soft, but they mould themselves to the user’s body shape regardless of their firmness. 

Overall, one of the most shared complaints that heavier people have regarding their sleep is that they wake up with certain body areas aching. However, memory foam will prevent these issues by contouring to the sleeper’s body shape. With that said, don’t forget that you still need a high-density memory foam option that can adequately support your weight.
