Discover expert insights on your sleep position. Professional advice and tips from LA Mattress Store to improve your sleep and comfort.
Before you fall asleep each night, your body settles into a familiar position — usually the same one you've used for years. You probably don't think much about it. But your sleep position has real consequences for how your spine, neck, and joints feel in the morning, and for certain conditions like snoring, acid reflux, and back pain.
Here's what each position means for your health — and practical tips for sleeping better based on how you naturally rest.
Back sleeping is widely considered the most supportive position for spinal alignment. When you lie flat on your back, your head, neck, and spine naturally fall into a neutral position — no twisting, no lateral bending, no artificial pressure on one side more than the other.
Health benefits:
Watch out for:
How to improve it: Use a medium-loft pillow that supports your neck's natural curve without pushing your head forward. Place a pillow under your knees to take pressure off your lower back.
Side sleeping is the most common sleep position among adults — and for good reason. It keeps the airway open (reducing snoring), is recommended during pregnancy, and is generally comfortable for most body types.
Health benefits:
Watch out for:
How to improve it: Use a firm, high-loft pillow that keeps your head in line with your spine. Place a pillow between your knees to keep your hips stacked and prevent your spine from twisting. A medium to medium-soft mattress works best for most side sleepers.
The fetal position — curled on your side with knees drawn toward your chest — is actually a variant of side sleeping, and shares many of its benefits. It's the most common position overall. If you sleep this way, you're in good company.
Health benefits:
Watch out for:
How to improve it: Sleep in a looser version — knees bent but not pulled tight. A pillow between your knees helps keep your spine aligned and reduces hip pressure.
Stomach sleeping is the hardest position to sleep well in. It's the least spine-friendly option because it forces your lower back into an arch and requires your neck to rotate to one side for the entire night. That said, it does reduce snoring, and if it's how you naturally sleep, there are ways to make it less damaging.
Health benefits:
Watch out for:
How to improve it: Use a very thin pillow (or none at all) under your head to reduce the neck rotation angle. Place a thin pillow under your pelvis and lower abdomen — this is the most important adjustment for stomach sleepers, as it significantly reduces the lower back arch. If you want to transition away from stomach sleeping, try starting on your side with a body pillow to hug — it removes the sensation of open space in front of you that drives many people to roll onto their stomach.
| Position | Spinal Alignment | Snoring Risk | Back Pain Risk | Best For |
|---|---|---|---|---|
| Back | Excellent | Higher | Low (with knee pillow) | Neutral sleepers, those without sleep apnea |
| Side | Good | Low | Low (with knee pillow) | Most adults, pregnant women, snorers |
| Fetal | Good (loose curl) | Low | Low-moderate | Comfort seekers, most adults |
| Stomach | Poor | Lowest | Highest | Only when other positions cause more discomfort |
Your sleep position should inform your mattress choice as much as anything else. Here's the quick version:
If you're not sure what works best for your position, come into any of our LA Mattress Store showrooms and test it. Lying on a mattress in your actual sleep position for a few minutes tells you more than any spec sheet.
Back sleeping offers the best spinal alignment for most people — as long as you support your knees with a pillow and don't have sleep apnea or snoring issues. Side sleeping is nearly as good and works better for people who snore or experience acid reflux.
Yes, with patience. The most reliable method is to use a body pillow or positioning wedge that makes the new position feel natural and the old one feel inconvenient. Most people adapt within a few weeks of consistent effort. Don't expect it to happen overnight.
For acid reflux and heartburn, yes — the stomach sits lower on the left side, which makes it harder for acid to travel upward. For circulation during pregnancy, left-side sleeping is also recommended. For general healthy adults, either side is fine.
Usually because your lower back isn't properly supported. When you lie flat without a pillow under your knees, the lumbar spine tends to flatten out. A pillow under the knees restores the natural curve and takes pressure off the lower back. It's also worth checking your mattress — a sagging or too-firm mattress can cause back pain regardless of your sleep position.
Indirectly, yes. If you're sleeping in a position that causes discomfort, pain, or snoring, you're more likely to wake during the night. A position that works with your body — and a mattress that supports that position properly — tends to mean fewer disruptions and more continuous sleep.
A medium-feel mattress works best for combination sleepers. It handles back and side sleeping reasonably well without being too soft for stomach sleeping. A responsive material — latex or a latex-hybrid — adapts more quickly as you shift positions compared to slow-response memory foam. Explore our mattress collection or stop by a showroom to test options in person.
