Top 6 Best Firm Beds Of 2021

Saatva — Best Firm Mattress

The Saatva mattress has several firmness levels available. The two firmest make our picks for being top-rated firm mattresses. These mattresses are built with a dual coil system of individually wrapped coils and a steel coil base. A plush Euro-top that is responsive makes sure you never feel stuck like can happen with even extra firm memory foam mattress.

Two layers of coils and an organic cotton cover

The combination of foam and coils make the mattress suitable for all types of sleepers and body types, although most will do best with the medium-firm model because the other is extra firm. Saatva falls in the middle of the range for the mattresses we’ve included here in this list; a queen retails for about $1,400.

Why this is one of our mattress recommendations — The various firmness options, extremely durable back-to-back coil construction and an affordable price point for a luxury mattress earned it a spot in our best firm mattress review.

Purple Hybrid — Best Medium Firm Mattress

The secret to the Purple Hybrid 2″, formally called the Purple 2, is its unique construction, which combines 7.5″ pocketed innerspring coils with a 2″ layer of the patented Hyper-Elastic Polymer.

This is the main comfort layer on Purple mattresses

This makes the mattress bouncy and responsive and gives it a feeling of being both supportive and pressure relieving at the same time. It’s one of the best medium firm mattresses if you like the unique feel. The price is a little higher than the average firm mattress online but not egregious considering how unique it is.

Why we picked this mattress — We ultimately chose Purple Hybrid because it’s a unique mattress that’s comfortable and supportive with x-factor features that people love.

Plank — Best Extra Firm Mattress

Plank Mattress is a new concept that lets you flip the mattress and enjoy either a “soft” side or a “firm” side. In truth, the soft side is more a medium-firm and the firm side is extra firm. This gives you two beds in one, and you can sleep on the side with the firmness you find most comfortable.

We think the mattress is good for petite and average individuals who sleep on their back or stomach, but heavy folks should probably look elsewhere. In terms of price, the Plank is one of the more affordable mattresses on our list.

Why this is one of the best firm mattresses online We put Plank on the list because it provides two firmness profiles in one mattress, making it versatile for back and stomach sleepers who need additional support. It also has a good value.

Avocado — Most Comfortable

One of the strong attractions of the Avocado mattress is the construction because it’s made from all-natural and eco-friendly materials. It combines steel pocketed coils and certified organic latex foam that gives a firm yet comfortable feel. You can also find Avocado as a medium-firm mattress if you opt for the topper.

This mattress is viable for all body types as you aren’t a petite side sleeper. It’s more expensive than the standard online mattress, but we think it’s a great value because of the upgraded organic materials and certifications.

What more can we say? Avocado is a super comfortable firm mattress

Why we picked this mattress — We picked the Avocado mattress for one of the best firm mattresses of 2021 because it is an extremely comfortable firm mattress made of all-natural, hypoallergenic materials.

Loom & Leaf — Best Semi Firm Foam Mattress

Loom & Leaf mattresses are almost foam and come in both a semi-firm and extra firm version. The semi-firm version would be good for anyone who likes a firm mattress, while the extra firm version is best for heavy people and back or stomach sleepers. 

In Loom & Leaf’s thick construction, you can find a layer of laminated cooling gel meant to help regulate temperature, as it’s the same material found in hospital burn units! If you don’t like memory foam’s tendency to retain heat, this bed is a much better option. 

This is the most expensive mattress on our list. However, people who like premium mattresses with support and cooling tech might not mind.

Loom & Leaf has a “firm foam” feel

Why we picked this mattress — It’s a luxury semi-firm mattress for those who love the slow responding feel of memory foam but hate how hot it sleeps. This thick foam mattress provides more support than your average all-foam bed, but it’s also able to provide some relief for those who sleep warm at night. It’s also one of the best extra foam memory foam mattresses if you go with that option.

Titan — Best For Heavy People

This bed is made for people who weigh over 250 lbs. As such, it is supportive and resilient, made with “TitanCaliber” coils. For heavy body types, it will be a comfortable semi-firm mattress. For petite to medium body types, Titan will likely be a little too firm.

Titan is a firm mattress made for heavy people

Titan is under $1,100 for the firm queen mattress and under $1,400 for the king size mattress before promotions. Post-discount, the queen should be under the $1K mark.

Why we picked this mattress — The people at Titan wanted to make a quality mattress that suited sleepers over 250 lbs, and we think this accomplishes that. It has a durable, supportive construction and an affordable price tag for such a good firm mattress.

Extra Firm vs Medium Firm

There’s a huge difference between extra firm and medium firm. Even luxury firm vs medium firm can be different. In our reviews, we consider extra firm mattresses to feel like a thin layer of foam on a board to represent the lack of pressure relief that an ultra firm mattress will offer. There are plenty of extra firm beds out there, but you will have a shorter list than if you were looking for a medium firm mattress, which is perhaps the most popular comfort level.

A medium-firm mattress offers a good amount of pressure relief but not so much that you’re “melting” into the bed. You should still feel the support but immediately recognize that this is semi firm, not ultra firm. The majority of brands offer a medium firm bed, or something just a little softer.

In our mattress recommendations, we always say it’s better to start too firm than too soft with your new bed, especially if you’re wondering what is the best firm mattress for your situation. Beds tend to get softer over time.

Finding The Best Rated Firm Bed For You

Changing mattresses can be difficult, especially when you’ve slept on a soft mattress for so long. Your body might need anywhere from several days to a full month to adjust to a new sleeping surface.

Why Purchase a New Mattress

Here are a few benefits of purchasing a new firm mattress:

  • Improved breathing and blood flow
  • Better spine and neck support
  • Improved overall sleep

Mattress Shopping Considerations

The process of finding a new mattress can seem daunting. We wish we could tell you plain and simple what the best mattress is for the money, but there are factors involved that make it dependent upon you and your preferences. With that said, here are a few things to consider when you’re shopping for a new mattress:

  • Your bed should be an investment in your life for the next 10-15 years. It’s where you spend about a third of your life. So we don’t suggest you pinch pennies unless you don’t plan on having your bed for the long-term. You can always look for a firm mattress sale if you want to save money.
  • Mattresses cost anywhere from $200 to over $3,000 (depending on size and quality). If you get a firm king mattress rather than a queen, you can expect to pay more.
  • Consider your sleeper type and weight. If you sleep on your back or stomach, a firm mattress can be beneficial for you. It can also be good for heavier sleepers who exert more pressure on a mattress, thus requiring more support. 

Doing some research before you shop and looking at mattress recommendations will help you answer the question, “what’s the best mattress to buy for me?”

Return Policies

Mattress reviews can’t tell you which bed you’ll like best. If you’re looking for an extra firm mattress, your idea of comfort may be different from most, because a majority of sleepers select a bed in the medium to medium firm range. Because of this, it’s important to get a mattress with a return period.

When you purchase from an online mattress company, you get to take advantage of their generous return and trial period policies. All of the brands listed above offer free shipping and will give you a risk-free trial period to make sure you find the most comfortable firm mattress for you.

Some brands give you an average of 100 days to test it out, while other companies like DreamCloud will give you an entire year. If you decide you don’t like your mattress within the trial period, you’ll be able to return your mattress for 100% of your money back. Most companies just urge you to wait at least 30 days before you make a final decision so you can allow your body to become acclimated to your new mattress.

Who Is A Firm Mattress Best For?

A poor mattress can have a huge impact on the quality of your sleep, as can a high-quality mattress. In general, firm mattresses are excellent for people looking for more support and relief from back pain. We’ll cover the specific considerations that might make firm mattresses your best choice.

Stomach And Back Sleepers

There are usually some specific qualifications for people who tend to seek out a hard mattress. First is that you’re possibly a back or stomach sleeper. These sleepers need a firm surface that won’t let their head, hips or shoulders sink into the mattress too much, which would cause the spine to curve or arch. You need to keep their spine in neutral alignment, which can prevent back pain and waking up with soreness. We notice that back sleepers typically like a firmer surface, perhaps even an extra firm one, and belly sleepers might need a little bit more cushion such as a medium firm mattress.

Back and stomach sleepers generally sleep more comfortably on beds that have a firmer profile, whereas side sleepers or combo sleepers need a little more cushion to provide pressure relief. We think the best option for stomach sleepers would be a medium mattress or firmer.

Heavy Individuals

Another reason you may want a firmer bed is that you might be a heavier individual. Firmness is a relative term to weight, which can make things tricky if you’re either much heavier (250 lb+) or much lighter (100 lb-). Heavier individuals tend to sink into a mattress deeper because they’re displacing more weight into it. This makes the bed feel softer for them. If you’re a heavier individual who sleeps main on their back or belly, or might just prefer an ultra firm bed in general, it can be more difficult for you to find what you’re looking for. Contrast that with someone that weighs under 150 lbs who will think even a semi firm mattress is extra firm.

People with Specific Medical Conditions

The last reason for wanting a harder sleep surface is that you might have a medical condition that requires a firm mattress every night. Whether that has to do with spinal issues, breathing issues or something else, always consult with your doctor before making a final decision and purchasing a new bed.

Before you begin shopping for a mattress, evaluate all of these considerations. Knowing your preferences ahead of time will make the shopping experience faster and easier. Understanding what you need will also help you ensure you’re making the best choice about your next mattress purchase.

Who Is A Firm Mattress Worst For?

If you’re a side sleeper, the best mattress for you is probably medium to soft. As a side sleeper, you’ll need more cushion to contour around your hips and shoulders. If your mattress is too firm, there will be too much pressure around these areas that can mis-align your spine and cause pain.

The Best Medium Firm Mattress Brands

We made one selection for the best medium firm mattress, there are a dozen or so fantastic beds in that firmness range.

These beds are some of the most popular. In many cases, people prefer a slightly firmer profile. In fact, if you want a bed to be firmer than a “medium,” you probably want to start a little up the firmness chain. Another reason would be that a medium firm mattress is accommodating because in many cases you can sleep in any sleeping position.

The best medium firm mattresses according to our experts are:

  • Leesa
  • Saatva
  • WinkBed
  • Avocado
  • Loom & Leaf
  • Purple

It’s not fair to say that above is an exhaustive list. We also left out plenty of beds that come in multiple firmness options, including Brooklyn Signature, Amerisleep, Helix Sleep and Nest Alexander. You may want to look through our mattress reviews page to see more beds.

Best Extra Firm Mattress Brands

There’s a huge number of people that outright prefer an extra firm mattress. You get a little cushioning, but not much. Here are the best extra firm mattress brands:

  • Plank
  • Saatva
  • Avocado
  • Brooklyn Bedding
  • Big Fig

We could make our list much longer, but that’s a fantastic place to start. Our selection is often Plank because it offers two firmness options. There’s the medium firm and the ultra firm, so it’s kind of like the best of both worlds, making it perhaps the best firm mattress if you’re not sure which you’ll prefer.

Pros And Cons Of Sleeping On A Firm Mattress


  • Excellent for heavy individuals – Because firm mattresses have more support, they’re less likely to sag and create discomfort for heavier individuals.
  • Spine alignment – Firm mattresses allow your spine to rest in a more neutral position, helping to relieve daily pain from slouching and curving.
  • Durability – Firm mattresses are built with more stability and are known to last longer than soft mattresses because you don’t sink into them as much. 


  • More painful for joints – People who suffer from conditions like arthritis might experience more pain from firm mattresses and increased pressure on their joints.
  • Breaking in period – If you aren’t used to a firm mattress, there’s a period of time where you’ll need to break it in and get used to it. It may feel too hard at first before you can get used to it.
  • Bad for side sleepers – A firm mattress might create too much pressure for side sleepers’ shoulders and hips

Once you’ve purchased your best mattress, enhance your comfort with some of the most popular firm mattress accessories:

  • Foam mattress topper – A foam mattress topper gives you a little more cushion if you’re still adjusting to your mattress or need a bit more contour while you sleep.
  • Sturdy foundation – A sturdy foundation is especially helpful for heavier individuals or couples. The foundation, like the one from Big Fig, serves as an extra support layer and provides additional durability.
  • Wraparound pillow – A wraparound pillow gives you extra support for your neck and shoulders. If you sleep on your side occasionally, a wraparound pillow can help relieve some of the pressure around your neck that the mattress might cause otherwise.
