6 Ways to Support Your Torso as a Side Sleeper

If you're a side sleeper looking for torso support, you're already ahead of 90% of side sleepers with shoulder pain. Most of them are still swapping one head pillow for the next, hoping this one will finally be different.

You've already figured out the part they're missing: the weight pressing on your shoulder comes from your torso. So that's where the support needs to go. The question now is how.

Torso support fixes one of two problems. Sinking: your torso presses down and the shoulder takes the weight. Rolling: your chest tips forward and the shoulder gets pinned underneath you, or your top shoulder collapses forward with nothing to rest on.

Here are six options, from free DIY methods to specialized solutions built for the job, like the Papaya Pillow. Some lift your torso. Some only keep it from rolling. And some get mistaken for torso support when they're really doing something else. For each one, you'll see what it fixes, what it doesn't, and who it's for.

1. Hugging pillows, pregnancy pillows and bolsters

This is the group most side sleepers already know. A regular pillow you hug against your chest. C- or U-shaped pregnancy pillows that wrap around your front, back and knees. Or a long, round bolster, a bedtime staple in much of Southeast Asia that you hug with your arms and legs.

They all do roughly the same job: they give your top arm and top leg somewhere to rest.

Without that, your top arm falls forward toward the mattress and pulls the top shoulder down and inward. Your top knee drops too, and twists your pelvis and lower back. A hugging pillow keeps both in a more neutral position.

What it fixes: rolling forward, top shoulder strain, and hip rotation. If the shoulder that hurts is the one on top, this is the first thing to try. It can also help if you have loose or hypermobile joints that tend to drift out of position during the night.

What it doesn't fix: your bottom shoulder. Nothing here lifts your torso. The shoulder you're lying on still carries the same weight as before.

Good for: top shoulder pain, hip or lower back discomfort, and anyone who wants a simple, low-cost first step.

2. Pillows with arm holes

These often get grouped with torso support, but most of them are head pillows. They have a tunnel or cutout so you can slide your bottom arm underneath without your head pressing on it.

That's useful if you like sleeping with your arm under the pillow and keep waking up with a numb or tingling hand. The arm hole takes the head's weight off your arm.

You'll also see them sold as couple pillows for spooning. The person behind can slide an arm through the tunnel and under their partner without it going numb. That's a nice feature, but again, it's about the arm, not the shoulder.

But your head isn't what's loading your shoulder. Your torso is. And an arm-hole head pillow doesn't change anything about how your torso sits on the mattress.

What it fixes: pressure on the arm from your head. Arm numbness if you sleep with your arm under the pillow.

What it doesn't fix: shoulder compression from your torso's weight.

Good for: people who sleep with an arm under the pillow and wake up with a numb hand. Not the right tool if your bottom shoulder aches from being pressed into the mattress.

3. DIY: a towel or pillow under your ribcage

This is where real torso support starts, and you can try it tonight with what you already have.

Lie on your side and place a folded towel or a flat pillow under your ribcage, just below your armpit. The goal is to lift your torso slightly, so your shoulder isn't the first thing pressed into the mattress. If one layer isn't enough, add a second or fold the towel thicker. Small adjustments in height make a noticeable difference.

You'll probably need a slightly higher head pillow too. Once your torso is lifted, your head sits higher than before.

You can also buy small foam waist wedges for side sleepers. They're basically a purpose-built version of the towel. They stay in place better, but they work the same way.

Another option is a generic foam wedge pillow, the kind sold for sleeping on an incline. It's firm enough to give real lift, but it's shaped like a ramp, not like the side of your body. Under your ribs, it tends to feel awkward and uncomfortable.

What it fixes: some of the shoulder compression. It's also the cheapest way to find out whether torso support helps you at all.

What it doesn't fix: it only supports one narrow area. Towels and pillows flatten and shift during the night, so you may wake up with it somewhere else entirely.

Good for: testing the idea before spending money. If you notice even a small improvement, torso support is probably worth pursuing.

4. A positioning wedge behind your back

This one comes from hospitals and care homes. Nurses use foam wedges behind the back to hold patients at a tilt of about 30 degrees instead of full side-lying, which takes pressure off bony points like the hip and shoulder. At home, the same wedges are mostly used for a simpler reason: to stay on your side and stop rolling onto your back.

You place the wedge behind your back. If you lie fully on your side against it, it mainly keeps you from rolling backward. If you lean back into it, some of your torso's weight goes onto your back and the wedge instead of straight down through your bottom shoulder.

What it fixes: rolling onto your back during the night. Leaning into it also relieves some shoulder pressure, but only because you're no longer fully on your side.

What it doesn't fix: it doesn't lift your torso. If you sleep fully on your side, your bottom shoulder carries the same weight as before. And if you're a committed side sleeper, the half-tilted position may feel like neither one nor the other.

Good for: people who have a hard time staying on their side, and side sleepers who are fine sleeping half-tilted toward their back.

5. An inclined wedge with an arm pocket

The best-known example is MedCline's Shoulder Relief System. A foam wedge puts your upper body on an incline of about 10 degrees, and your bottom arm drops into a pocket at the top so it isn't pinned underneath you. A separate body pillow in front gives your top arm somewhere to rest.

What it fixes: the wedge and arm pocket take pressure off your bottom shoulder, and the body pillow keeps you from rolling forward.

What it doesn't fix: the incline tilts your whole upper body, not just the area under your shoulder. It's a large, fixed system that takes up about half a queen-size bed. And once your arm is in the pocket, turning over or changing position takes more effort.

Good for: side sleepers with shoulder pain who have the bed space and don't mind sleeping on a slight incline.

6. Continuous torso support (the Papaya Pillow)

The Papaya Pillow is built on the same idea as the towel trick, but it supports the whole torso instead of one narrow strip.

It sits under your body from your ribcage down to your hip. The memory foam is contoured to the shape of your side, so the weight of your trunk is spread along its full length instead of pressing down through the shoulder.

You use it together with your regular head pillow. Between the two, there's a gap: the Shoulder Gap. Your bottom shoulder rests in that space instead of being pinned against the mattress. You can make the gap bigger or smaller by sliding the pillow up or down the bed.

Compared with an inclined wedge, it lifts your torso without tilting your whole body. Because it's separate from your head pillow, you can also push it aside if you roll onto your back, and pull it back when you return to your side.

What it fixes: compression of the bottom shoulder, and the forced, rolled-forward shoulder position that comes with it.

What it doesn't fix: your top arm. If your top shoulder hurts, pair it with a hugging pillow. Expect a few nights to adjust, and probably a higher head pillow.

Good for: committed side sleepers whose main problem is the bottom shoulder being pressed into the mattress. It's not for you if you mainly sleep on your back.

If you want to try it, you have 30 days to test it with the No Pressure Guarantee. That's enough time to get used to it and see whether it helps.

Which one should you try first?

It depends on which shoulder hurts.

If it's your top shoulder, start with a hugging pillow or bolster. Give your top arm somewhere to rest and see if that's enough.

If it's your bottom shoulder, the one pressed into the mattress, that's a compression problem. Hugging pillows and arm-hole pillows won't change much. Try the towel under your ribcage first. If that helps even a little, torso support is the right direction, and a dedicated option like the Papaya Pillow or a wedge is the next step.

If both shoulders hurt, combine them: something under your torso, and something to hug in front.

Whatever you try, give each change about a week before you judge it. The first few nights in a new position often feel strange.

And if your pain keeps getting worse, wakes you up several times a night, or comes with weakness or numbness that doesn't fade once you're up, talk to a doctor or physical therapist. A pillow can take pressure off your shoulder, but it won't treat an underlying condition.

One more note: any option that lifts your upper body, including wedge systems and the Papaya Pillow, can bother your lower back or hips. If you have problems there, check with your doctor or physical therapist before you try one.
