Key takeaways from our testing
Two firmness levels at a great price. If you’re a stomach sleeper who loves their mattress as firm as possible, the Plank Firm could be a good choice. It has two firmness levels — firm on one side and extra firm on the other — so you can sleep on the right side for you. The firm side has a slightly lofted quilted top and a responsive foam layer. The extra-firm side has a flat quilted top and a denser foam layer. You're essentially getting two mattresses in one with this affordably priced bed.
The Plank Firm is made with dense memory foam. The extra-firm side is facing up. The less-firm side (facing down) has an “egg crate” design to provide more cushioning.

Firm side has minimal motion disturbance. Tester Bryan, a 62-year-old combination sleeper who often sleeps on his stomach, gave the mattress a near-perfect motion isolation rating on the bed’s firm side. “I could go from stomach to side without causing any major disturbance,” he said. Our lab team credits this to the slight cushion from the quilt and foam on this side, which helps absorb motion. However, when he tested the mattress on the extra-firm side, Bryan said the foam felt so dense the whole bed moved: “It’s so firm it can’t absorb any motion.”
Best suited for higher-weight sleepers. Testers emphasized this bed is truly for those who love a firm feel or higher-weight people. That’s because higher-weight sleepers generally find a firmer bed more comfortable, since it prevents their midsection from sinking too deeply and curving their spine too much. Donna, an average-weight tester, awarded the Plank Firm middling rating for relieving pressure while lying on her stomach. “I feel a little pressure in my chest and spine but not too much,” she said. In contrast, Bryan, a higher-weight sleeper, loved sleeping on his stomach on the Plank Firm. “I feel very good on my stomach, which I’m not used to,” he said. “My spine is aligned, and no area of my body is sinking in too much.” He scored it a 4.5 out of 5 for pressure relief.

Key takeaways from our testing
Comfortable mix of soft top and supportive coils. Stomach sleepers are usually most comfortable on medium-firm to firm beds, which help keep the spine neutral, so a truly soft bed didn’t make this list. Instead, we selected the Nolah Evolution Luxury Firm, which has a medium-firm feel, with a soft pillow top that gave us the impression of a soft bed while providing adequate support. “It has a high pillow top that’s soft and plush,” said tester Lauren, a 54-year-old stomach sleeper, “and the springs underneath provide a ton of support.”
Lauren said the Nolah Evolution Luxury Firm felt firm but provided good cushioning.

Movement-boosting materials. Testers loved how bouncy the mattress felt, making it easy to get out of bed. “I feel like it’s just springing me out of bed,” Lauren said. “I just need my legs to stand.” The mattress also nabbed a first-rate score in our bounce test.
Extra-tall profile. The 15-inch Nolah Evolution can be challenging for some people to climb into. (Most mattresses are between 8 and 12 inches tall.) Moreover, one 69-year-old focus group participant said their 15-inch bed needs deep-pocketed fitted sheets, which are more difficult to change. If you prefer a shorter bed, we suggest looking at the Helix Midnight — it’s softer than the recommended firmness range for stomach sleepers, but our testers found it still works well due to its strong support system.
How we tested the best mattresses for stomach sleepers
We started our process by researching the market. What mattresses are popular and why? Who has the best customer reviews — and are the reviews legitimate? After talking with medical experts, we narrowed our list from 50 mattresses to the more than 30 we tested in our lab.
To identify their strengths and weaknesses, we used controlled tests to assess performance metrics like edge support, bounce and temperature regulation. Then we recruited more than 15 testers ages 50 and older to give us their unbiased feedback.
These testers answered questions like: Did the mattresses provide good pressure relief when lying on your stomach? Do your hips sink in enough? Is the bed firm enough to support the natural curve of your spine? Beds that excelled in our tests made our list of the best mattresses for stomach sleepers.

Below are some of the most important considerations for stomach sleepers when shopping for a new bed based on input from our medical experts, interviews with our focus group participants, responses from our survey participants and our lab test results.
Keep in mind these are comfort considerations — not clinical advice. If you’re looking for the best mattress to address a health condition, consult your doctor for recommendations that complement your treatment plan.
Firmness and spinal support
Most brands rate a mattress’s firmness level from 1 to 10, with 10 being the firmest. Verebes, the physical therapist in New York City, recommends medium-firm to firm mattresses (6.5 to 9 out of 10) for stomach sleepers to maintain spinal alignment. “Stomach sleeping naturally places the lower back in an extended position," she says. "If a mattress is too soft, the pelvis sinks too deeply, which increases the arch in the lower back and can lead to stiffness or discomfort over time."
Firmness recommendations aren’t rigid
Brands often recommend medium-firm to firm mattresses for stomach sleepers. However, our lab team found medium mattresses with strong support systems, like the Helix Midnight, can work well for many stomach sleepers.
Some testers said they prefer a slightly softer mattress — in the medium range — to relieve pressure from their chest. While firmness level recommendations for sleeping positions are a great place to start, they’re not hard-and-fast rules. Based on our testing, we’ve found that medium mattresses can work well as long as they have strong support systems. Verebes says latex, dense foam or hybrid beds with a thinner comfort layer tend to perform best.
Pressure relief
Most mattresses on our list pair firmness with above-average pressure relief to cushion common contact points for stomach sleepers like the hips and chest. Based on our testing, we suggest looking for a mattress with forgiving materials in the upper layer, like a pillow top or quilted foam.
The mattresses on this list earned a minimum of 4 out of 5 for stomach sleeping pressure relief.
Responsive materials for easy movement
Our lab team found that more responsive materials, such as high-density foam or bouncy coils, help stomach sleepers reposition or get out of bed more easily.
A bed made with responsive materials is especially important for those with painful conditions. According to our survey, people with orthopedic conditions, like shoulder pain, rate mattress accessibility almost twice as important as those without pain. A physical or occupational therapist can help find easier ways for you to move or suggest positional adjustments to help you sleep with less pain while you manage your condition.
Durable construction
Stomach sleepers need a mattress with strong, sag-resistant materials to keep their spine neutral. Mattresses that are too soft, or beds made with overly forgiving upper foam layers, may develop lumps that can cause the spine to dip uncomfortably.
Based on our lab tests, zoned support systems typically do an outstanding job reinforcing the center of the mattress, which is where most people carry the majority of their body mass or need extra support. High-density foams or latex beds also hold their shape longer than softer options.
Cooling and breathability
Pillow placement can help
Verebes says pillows can help you find the most comfortable stomach-sleeping position. She recommends placing a pillow under one hip to reduce strain on the lower back. She also recommends putting a small pillow under your stomach or lower chest to provide additional support.
Stomach sleepers may find a large area of their body is in constant contact with the bed’s surface. That’s because over the course of the night, body heat transfers into the mattress’s surface, and some materials dissipate this heat better than others. Hot sleepers should consider breathable mattresses for a more comfortable night’s rest.
Our lab team found that cooling capabilities vary widely across mattresses. Some cooling materials, like GlacioTex, help certain beds regulate temperature well. Thick pillow-top mattresses and all-foam beds performed less consistently in our tests. Beds with thick springs, quilted covers or aerated upper form layers, like the Leesa Hybrid Sapira Chill, allow for more airflow.
Is it good to sleep on your stomach?
Some sleep and ergonomic experts advise against sleeping on your stomach because it doesn’t support spinal alignment. Also, stomach sleepers have to twist their necks to breathe, which can cause discomfort over time.
Still, some people prefer sleeping on their stomachs, including Verebes. “I know stomach sleeping isn’t the ‘ideal’ position from a biomechanics standpoint, but it’s the position I find most comfortable,” she says.
In her professional experience, sleep quality is the number one priority, regardless of sleep position. “While we can talk about ideal sleep positions from a medical standpoint, the reality is poor sleep often does more harm than an imperfect position," she says. "I remind patients that the goal is not to force a perfect posture all night, but to find a position that allows them to sleep comfortably and consistently, with as little strain on the body as possible."
If you’re a devoted stomach sleeper, accounting for it in your exercise routine may help prevent adverse effects. Verebes makes sure to stretch before working out, and she keeps her core and hips strong. She also positions herself with pillows when she’s lying on her stomach to reduce strain on her neck and lower back.
Who shouldn’t sleep on their stomach?
Verebes says there are cases where she advises patients against sleeping on their stomach. She says stomach sleeping can exacerbate symptoms in people with neck pain because of the rotated head position. She also says that stomach sleeping can worsen symptoms in people with moderate to severe spinal stenosis because of the spine’s extended position, and those with shoulder pain might find arm positioning challenging while laying on their stomach.
People with certain heart-lung or breathing conditions, like advanced chronic obstructive pulmonary disease (COPD) or sleep-related breathing issues, may have more difficulty breathing while sleeping on their stomach.
How much do the best mattresses for stomach sleepers cost?
FAQs
What is the best type of mattress for stomach sleepers?
The best mattresses for stomach sleepers tend to be firmer hybrids or dense foam beds because they provide enough support to prevent the hips from sinking too deeply into the bed, which can strain your back. But keep in mind there’s no one ideal mattress type for everyone.
Should stomach sleepers use a soft or firm mattress?
Many experts recommend stomach sleepers use a medium-firm to firm mattress, which fall within the 6.5 to 9 out of 10 firmness range. These beds offer the most support under the hips, which keeps the spine neutral and more comfortable throughout the night.
What type of pillow should stomach sleepers use?
Thin pillows — or no pillows at all — are usually best for stomach sleepers. Thick pillows can push the neck into an exaggerated rotated position that may be uncomfortable or painful.
