What is the Best Mattress for Back Sleepers in 2026?
By Sabrina Almeida
For back sleepers, the best mattress is typically a medium-firm option (rated around 5–7 on a 10-point firmness scale) that provides robust lumbar support without allowing your hips to sink too deeply. The Endy Mattress and Endy Hybrid Mattress are both engineered with back sleepers in mind, using open-cell Endy Cooling Comfort Foam and zoned pocket coils respectively to maintain neutral spinal alignment. With over 1 million Canadians trusting Endy, a 15 year warranty and a risk-free 365-night trial, you can feel confident that an Endy mattress will help to keep your spine properly aligned.This guide will walk you through our top picks for back sleepers, how to choose the right firmness for your body type, and everything else you need for a great night's sleep.What Is Back Sleeping?Back sleeping — also known as supine sleeping — is the second most common sleeping position, after side sleeping. As a back sleeper, you sleep with your face and chest facing upward, with your weight distributed along the length of your spine.The good news: maintaining proper spinal alignment during sleep reduces back pain and supports overall spinal health. Back sleeping naturally lends itself to that neutral spine position — as long as you have the right mattress underneath you.
5 Things to Look For in a Mattress for Back Sleepers
Understanding what makes a mattress well-suited to back sleeping will help you make a more informed choice, whatever you decide.
1. Medium-Firm Support
The general rule for back sleepers is to look for a medium-firm mattress (5–7 on a 10-point scale). This keeps the spine supported without letting the hips sink too deeply. A mattress that's too soft can cause the spine to curve unnaturally over time, leading to discomfort or pain.
2. Contouring and Pressure Relief
Support is essential, but comfort matters too. Look for a mattress that contours to the natural curves of your body — particularly the lumbar region — to relieve pressure points without sacrificing proper alignment. Unlike side sleepers who need softer shoulders and firmer hips, or stomach sleepers who need firm support to prevent lower back sag, back sleepers require balanced medium-firm support that maintains the spine's natural S-curve without letting the hips sink too deeply.
3. Spinal Alignment
Your mattress should keep your spine in a neutral position throughout the night, supporting the natural curvature of your lower back without letting it collapse or arch unnaturally. This is especially important in the lumbar region, where most back pain originates. For more information on choosing the best mattress for back pain, check out our blog post here.
4. Material and Construction
Different materials feel and perform differently. Endy's open-cell polyurethane foam is designed for better airflow and comfort than traditional memory foam, while the Endy Hybrid combines that foam with pocket springs for added structure and zoned support. Unlike latex mattresses, Endy's foam is temperature-insensitive — maintaining a consistent feel year-round, no matter the season.
5. Motion Isolation
If you share your bed with a partner, good motion isolation means one person's movement won't disturb the other. The Endy Mattress excels here — its Pressure Relief Foam absorbs and isolates movement, so your partner’s movement won’t wake you up at night.
Choosing the Right Firmness for Your Body Weight
How firm a mattress feels is personal — and body weight plays a bigger role than many people realize. A mattress that feels perfectly supportive to one person can feel too soft or too firm for another, even at the same rated firmness. Here's a practical guide:
Under 130 lbs: A soft (3/10) to medium (5/10) feel tends to work well. Sleepers under 130 lbs don't compress a mattress as deeply, so a softer surface can still provide adequate support without creating excess pressure on the spine.
130–230 lbs: Medium-firm (6/10) is the sweet spot for most back sleepers in this weight range — and it's exactly where both Endy mattresses land. This keeps the hips from sinking too far while still allowing the mattress to contour comfortably to the lower back. The Sleep Foundation confirms (https://www.sleepfoundation.org/best-mattress) that medium-firm is the most widely recommended option for back sleepers in this weight range.
Over 230 lbs: Heavier back sleepers often benefit from a firmer feel (7+/10) to prevent the midsection from sinking out of alignment. We recommend the Endy Hybrid Mattress for this weight range, as its zoned pocket coils provide the added midsection reinforcement that heavier sleepers need.
When in doubt, Endy’s 365-night trial takes the guesswork out of the decision — giving you a year’s worth of real sleep to find out whether your mattress is truly working for your body.

2. The Endy Hybrid Mattress — Best for Back Sleepers Who Want Extra Lumbar Support
The Endy Hybrid Mattress combines the contouring comfort of our acclaimed Endy Cooling Comfort Foam with durable, Canadian-made pocket coils — making it an exceptional choice for back sleepers who want targeted support where it counts most.What sets the Endy Hybrid apart is its zoned support system. The pocket coils are firmer in the center third of the mattress, providing targeted lumbar support to prevent hip sinkage while allowing the shoulders to sink comfortably. This zoned architecture is particularly beneficial for back sleepers who need extra midsection reinforcement, keeping the spine's natural S-curve intact throughout the night. According to the Sleep Foundation, zoned lumbar support is one of the most important features to look for in a mattress designed for back sleepers.A plush, quilted top layer rounds out the feel, balancing structure with the kind of pressure relief that makes for genuinely restful sleep. The Endy Hybrid is rated medium-firm (6 on a 10-point scale) and is proudly made in Canada, with foam poured locally at facilities in Ontario and Quebec.Best for: Back sleepers between 130–230 lbs who want extra lumbar support, or heavier back sleepers (230 lbs+) who need firmer midsection reinforcement.
The contouring comfort of foam + extra lumbar support from pocket coils = a great night's sleep for back sleepers. See how the Endy Hybrid's zoned support system gives extra midsection reinforcement to keep your spine in a natural shape throughout the night. Shop the Endy Hybrid Mattress

Don't Forget Your Pillow
Finding the right mattress is only half of the solution. As a back sleeper, your pillow plays an important role in maintaining proper spinal alignment from head to tailbone.Endy's Memory Foam Pillow provides optimal cushioning for back sleepers, comfortably cradling the neck and supporting the head without pushing it too far forward. It's breathable, quick-response, and designed for a cooler sleep.For something more tailored, Endy's Customizable Pillow lets you adjust the height and firmness to match your specific needs — a great option if you've struggled to find a pillow that truly feels right.When choosing a pillow as a back sleeper, keep these factors in mind:
Medium to low loft — high enough to fill the gap between your neck and the mattress, but not so high that it pushes your head forward
Firm enough support to prevent your head from sinking too deeply and curving the spine unnaturally
Contouring comfort that adapts to the shape of your head and neck
Good breathability to help prevent overheating through the night
Pros and Cons of Back Sleeping
Back sleeping is generally considered one of the healthier sleeping positions — but like any position, it has its trade-offs.Pros:
Spinal alignment: Back sleeping helps maintain the natural curve of the spine, supporting good posture and reducing the likelihood of back and neck pain.
Reduced facial wrinkles: With your face not pressed into a pillow, back sleeping can help prevent skin creasing and breakouts over time.
Less acid reflux: Gravity helps keep stomach acid from flowing back into the esophagus when you're lying on your back.
Cons:
Snoring and sleep apnea: Back sleeping can worsen snoring and obstructive sleep apnea symptoms, as the tongue and soft tissues in the throat can obstruct the airway more easily in this position.
Discomfort for certain conditions: Some health conditions may be aggravated by back sleeping — it's worth speaking with a healthcare provider if you experience recurring discomfort.
Increased risk of sleep paralysis: Some back sleepers may be more prone to experiencing sleep paralysis, a temporary inability to move or speak while transitioning between sleep stages.
Frequently Asked Questions
What mattress firmness is best for back sleepers?Medium-firm (around 6 on a 10-point scale) is the most widely recommended firmness for back sleepers. It provides enough support for proper spinal alignment without letting the body sink too deeply. Most back sleepers between 130–230 lbs will find this range ideal. Heavier sleepers (230 lbs+) may benefit from a firmer option (7+) or a mattress with zoned support, like the Endy Hybrid.Do back sleepers need a soft or firm mattress?Neither extreme works well. A soft mattress lets the hips sink too far, pulling the spine out of alignment. A very firm mattress doesn't allow enough contouring in the lumbar region. Medium-firm sits in the middle — offering support alongside the pressure relief that makes for genuinely comfortable, restorative sleep.What's the best foam mattress for back sleepers?If you prefer an all-foam feel, look for open-cell or polyurethane foam rather than traditional memory foam. Memory foam tends to retain body heat and can create a slow, sinking sensation that doesn't work well for all back sleepers. Endy's open-cell foam is temperature-insensitive and designed for better airflow, giving you the contouring benefits of foam without the heat retention.What is the best mattress thickness for back sleepers?A thickness of 10–12 inches is generally suitable for most back sleepers. Both the Endy Mattress and Endy Hybrid Mattress in medium-firm fall within this range and are well-suited to the support needs of back sleeping.Is an organic mattress better for back sleepers?Organic mattresses have their appeal, but they can come with limited firmness options — making it harder to find the exact feel that works for your body. If material safety is a priority, look for certifications on conventional mattresses. Both Endy mattresses carry CertiPUR-US® certification (https://certipur.us/), meaning the foam is free from formaldehyde, phthalates, flame retardants, and heavy metals; it's also certified for extremely low VOC (volatile organic compound) emissions for indoor air quality (less than 0.5 parts per million). This is a meaningful assurance that our mattresses are safe for even the most sensitive sleepers in your house.All Endy mattresses come with a 365-night trial and a 15-year warranty. Over 1 million Canadians have trusted Endy for a better night's sleep.
