The best firm mattress is not necessarily rock hard. In fact, it’s quite the opposite. In our mind, the best firm mattress will be firm but not unyielding. It will have a combination of firmness, comfort, and support. Keep reading to learn more.


Quick Picks for the Best Firm Mattress

Later, we discuss the details of why these mattresses made our list of top firm mattresses and a whole lot more.


What are the Benefits of a Firm Mattress?

The best firm mattresses will provide a host of benefits to sleepers of all types. Some noteworthy benefits include:

Support – firm beds provide ample support where you need it most. This helps to reduce the risk of back and neck problems, and keeps you sleeping soundly.

Spinal Alignment – firm mattresses can help to keep your spine aligned properly by providing even support. With that said, you don’t necessarily want to go too firm, as that can cause uneven support.

Weight Distribution – firm mattresses do a great job of providing good weight distribution support. In other words, they support your whole frame, instead of just certain areas. This is particularly important for heavier folks.

Durability – by nature, firmer materials sag less and last longer. While those super-soft mattresses might be comfortable at first, they simply don’t have the same durability as a hard mattress.


Who Should Sleep on a Firm Mattress?

There’s no one-size-fits-all solution in the mattress world. Some folks will do best on firmer beds, while others will get better sleep on softer models. Here are some of the groups that tend to sleep well on firm beds:

Sleepers with Back Trouble – If you have back pain or health problems associated with back pain, you probably need the support that is offered by the firmest mattress. With back problems, you really need a mattress that is firm enough to keep your back aligned without allowing you to sink like a soft mattress might. Although, experts warn that sleepers with back pain don’t necessarily need a super firm mattress, and might do well with a medium-firm. See our guide to the best mattresses for back sleepers for more information.

Stomach Sleepers – If you sleep on your stomach and your mattress is too soft, it could cause your pelvis to sink, which can lead to back problems due to a misaligned spine. The top firm mattresses will stop your back from arching, which will help to avoid unnecessary problems. See our guide to the best mattresses for stomach sleepers to learn more.

Heavier Sleepers – If you are overweight, or just a large person in general, you’ll likely sleep better on a firm mattress. Firmer bed models have a better ability to support your body evenly, keeping your spine aligned properly. Soft beds, on the other hand, can create too much sag for heavy sleepers, which can lead to discomfort.


Who Shouldn’t Sleep on a Firm Mattress?

Lighter Sleepers – While a firmer mattress is advised for heavier sleepers due to sinkage and other factors, lighter sleepers might want to avoid firmer mattresses for the same reason. If you don’t carry a lot of weight, even the best firm mattress may be too firm and not allow enough give for you to sleep comfortably.

Personal Preference – If you’re someone who prefers the “hug” of a soft mattress that conforms more to your body, you’ll probably want to avoid firm mattresses. This is a matter of personal preference, so it’s going to be somewhat subjective – but it’s important to recognize your own likes and dislikes when choosing a new mattress.

Where this model gets particularly interesting, though, is in the smart features. It comes with a smart cover that rests on top of the mattress. This cover syncs with your smartphone and smart home setups, and can do a lot to improve your sleep. It tracks 15 different factors, including heart rate, respiratory rate, sleep cycles, and more.

Kaya is an innovative hybrid mattress that combines 5 layers: pocketed coils, transition foam, memory foam, responsive HD foam, and a ThermoGel infused cover. These layers provide the perfect combination of firm support (primarily from the coils) and luxurious comfort from the foam – while the cooling cover rounds things out by helping you avoid sleeping hot.

Kaya is offered at an incredibly reasonable price. We’d call it a medium-firm, or perhaps a medium – so, if you’re after a very firm mattress, this probably isn’t the best choice. With that said, Kaya Sleep truly stands behind their products with a 120-day risk-free trial offer and an incredible 20 year warranty.

How We Chose the Best Firm Mattress of 2020

There are a staggering number of different mattress models out there – so how did we possibly choose the best ones? In our search, we focused on these factors:

Firmness – while this one should be somewhat obvious, it’s also quite important. We focused on finding models that fell in the medium-firm to firm range. In most cases you won’t want a hard mattress, so we narrowed it down to models in the sweet spot of support levels.

Comfort – some firm models tend to sacrifice comfort for the sake of firmness – which we just don’t understand. You can definitely have the best of both worlds, so we focused our efforts on identifying models with excellent comfort (both initial and long-term).

Cooling – some mattress models tend to “sleep hot”, which can be a problem for those living in hot climates or those who simply run warm at night. We focused on models with good cooling properties.

Motion Transfer – since many of our readers share their beds with a partner, we sought to identify beds with minimal motion transfer. The models we chose have excellent motion isolation, meaning you won’t disturb your partner by tossing and turning or even getting out of bed.

Value – we want our readers to sleep better, and (unlike the mattress store down the street) we don’t want them to spend a fortune on a new mattress. We chose beds that are affordable and provide excellent value.

Perks – when buying a mattress online, it’s important to know that you have some flexibility if things don’t work out. Even the best firm mattress might not be the right fit for everyone. So, we chose models that offer great extended trial periods, typically of 3 months or more. We also went with companies that have good warranties and helpful customer service.
