Best Extra-Firm Mattresses Of 2025 For All Types Of Sleepers (Tested)
While every sleep setup should share a few key similarities to maximize sleep quality—such as minimal light and noise pollution—other factors are personal.
One preference that's likely to vary from person to person? Mattress firmness.
A few factors can affect the right mattress firmness for you, including your sleep position, body weight, and any issues with chronic pain.
So while the thought of snoozing on the best extra-firm mattress may not be for all, it's a fairly popular pick for those who sleep on their stomach or need more support.
And because we understand the importance of a good night's sleep and the pivotal role a quality mattress plays in achieving it, we meticulously selected a range of extra-firm mattresses from top brands renowned for their quality and craftsmanship.
Our team of testers spent countless hours assessing comfort, durability, and support levels, considering various sleep preferences and body types.
Below, find our top picks for the best extra-firm mattresses on the market, per sleep experts and testers.
- Best overall: Plank Firm by Brooklyn Bedding
- Best latex: Avocado Organic Latex Mattress
- Best hybrid: Saatva Latex Hybrid Mattress
- Best with same-day shipping: Sleep On Latex Pure Green Organic Latex Mattress
Mattress type: Memory foam | Sizes available: Twin, XL-twin, full, queen, king, CA king, split CA king, short full, short queen, olympic queen, short king, RV king | Firmness options: Firm, extra-firm
Plank's name should tip you off to everything you want to know about this flat design. The flippable mattress gives just two options to sleepers: firm and ultra-firm.
According to the brand, achieving anything more firm than the "ultra-firm" side would require you to sleep "directly on the floor."
What that really means? Each side of the memory foam mattress has a different type of cushioning. One side has less than an inch of pillow cushioning, while the other provides twice the cushioning and a 2-inch foam comfort level.
We chose this mattress as our top pick simply because we were impressed by its innovative design offering multiple options within a single mattress.
It's unique flippable design allows sleepers to tailor their sleep experience to their precise needs, whether seeking substantial support or a slightly softer feel.

What to look for in an extra-firm mattress
- Price: It's possible to find an extra-firm mattress on a budget under $300, but there are plenty of splurge-worthy options available, too.
- Warranties: Your mattress is an investment, so it's important to find a design that's constructed to last. A warranty is a great way to suss out what's built for the long haul.
- Sleeping position: Stomach and back sleepers will love the support offered by an extra-firm mattress, which helps maintain proper alignment by reducing the sinking common in softer constructions.
- Weight limit: An extra-firm mattress can be a great option for people who weigh more than 230 pounds, but it's important to look at the weight limit to ensure the construction offers enough support.
How we picked
- Firmness: Unfortunately "firmness" varies by brand, so the label extra-firm isn't always enough to ensure the mattress has zero give. To get as close as possible, we only selected mattresses at the top 20% of the firmness scale for each company.
- Certifications: We focused mainly on mattresses made of GOLS-certified organic latex and GOTS-certified organic cotton. However, when that wasn’t possible we looked into manufacturing processes to make sure the mattresses were environmentally conscious.
- Testing: We called all mattresses into our testing studio to determine whether they provide pressure relief, motion isolation, and edge support. Our findings were included as star ratings for each pick.
- Sleeping positions: You may notice a few less firm options in our guide; these accommodate side sleepers who need a firmer option but can't commit to the rock-solid feel of an extra firm pick.
What we skipped
Prior to testing for this buying guide, our team previously included the Zinus Pressure Relief Extra Firm iCoil® Hybrid Mattress.
Upon further examination, we felt this budget-friendly pick didn't offer the same quality of materials provided by the other options in the guide.
The brand also underwent scrutiny last year for including fiberglass in its mattress, which is used to as a natural flame retardant to prevent the use of chemicals.
However, regular wear-and-tear of a mattress can allow these small fragments to escape the covers used in many mattress—leading to negative health consequences.
How do brands measure firmness?
Brands typically rate mattress firmness on a scale of 1 to 10. A lower number indicates softer cushioning, while higher numbers point to an extra-firm design.
While nearly all mattresses feature a comfort layer made with cushioning or responsive foam, soft mattresses tend to have thicker comfort layers versus the thinner layer on firm designs.
Although many brands use the same 10-point scale, there is no universal metric for firmness. As a result, it's important to read into the construction of every mattress to better understand how it may fit your preferences.
Who should sleep on an extra-firm mattress?
Side sleepers beware—an extra-firm mattress is not for you. Chiropractor Kevin Lees, D.C., of The Joint Corp previously told mbg that "a mattress that is too firm may cause shoulder and hip pain, as well as change the spinal alignment."
That's because side sleepers put pressure on their shoulders and hips, which needs to be counteracted by the mattress. An extra-firm mattress won't provide this responsiveness, making them a hard sell.
However, stomach and back sleepers can find an oasis in this solid construction.
The firm base keeps your spine in a neutral alignment when lying on your stomach or back, preventing your risk of aches and pains.
The extra-sturdy construction is also ideal for those who weigh more than 230 pounds, which is often the max weight considered for many designs.
Of course, you're the best judge of how firm you want your mattress to be. Take advantage of trial periods, flippable mattresses, and free returns to find the right firmness level for you.

What we've updated since publishing this article
February 2024: After completing a series of experiments on our mattresses in our testing studios, we updated this guide to reflect our findings pertaining to motion isolation, pressure relief, responsiveness, and edge support. Hands-on access to these mattresses allowed our testers to determine how firm each mattress truly felt, so we could find the "firmest" option on the market. During these tests, we discovered the Saatva Latex Hybrid was softer than anticipated based on the brand's firmness rating. However, our testers who sleep on their side felt this was one of the firmest options they could sleep on without causing shoulder or hip pain.
