Why side sleepers reach for a wedge
The two most common reasons are reflux and snoring or sleep apnea, and side sleeping helps with both. For reflux, NIDDK suggests raising your head 6 to 8 inches by putting a foam wedge or extra pillows under your head and upper back, and Mayo Clinic suggests starting the night on your left side to make reflux less likely. The Sleep Foundation adds that there is evidence left-side sleeping may help curb acid reflux symptoms.
For sleep apnea, the Sleep Foundation ranks side sleeping as the best position and head elevation of 30 to 60 degrees as the next best. A wedge lets you combine them. Our wedge pillow for sleep apnea guide covers that use in detail.
The side sleeper problem with wedges
On a narrow, steep wedge, your lower shoulder jams into the slope, your body slides toward the low edge, and your waist bends sideways at the bottom of the wedge. The Sleep Foundation notes that when you lie on your side, the shoulders and hips bear the brunt of your weight, which can create pressure points. A steep wedge concentrates that pressure even more.
| Wedge design | Side sleeper fit | Why |
|---|---|---|
| Short and steep | Poor | Bends you at the waist and loads the shoulder |
| Long, gradual slope | Good | Lifts the torso evenly so hips and shoulders stay in line |
| Wide (spans most of the bed side) | Good | Room to curl slightly and change sides |
| Wedge with shoulder or arm cutout | Good | Lets the lower shoulder and arm sink in |
| Under-mattress wedge or adjustable base | Very good | Raises the whole mattress, so your usual side position stays the same |
How to set up a wedge for side sleeping
- Choose your side. For reflux, start on the left, as Mayo Clinic suggests.
- Lie so the slope begins at your hips, not at your ribs. This keeps your spine in a straight, tilted line.
- Put a normal-height pillow on top of the wedge to fill the gap between your ear and shoulder. Pick the loft from our side sleeper pillow guide.
- Keep your arms by your sides or slightly in front of you, with arms and hands aligned, as the Sleep Foundation suggests.
- Place a small pillow between your knees so the top leg does not drop and twist your spine. Our side sleeper knee pillow guide explains sizes.
- Use a pillow behind your back if you tend to roll off the slope.
Common mistakes
- Relying on stacked pillows. Mayo Clinic says raising your head with extra pillows is not effective for reflux. Stacked pillows tend to bend the neck rather than raise the torso.
- Starting too steep. Begin with a gentler angle and adjust.
- Ignoring the hips. If your hips are on the flat mattress and your chest is on a steep slope, your spine bends sideways.
- Choosing a narrow wedge if you turn often during the night.
Who should be careful
The Sleep Foundation notes that people with heart failure may feel short of breath lying on their left side but not on their right. If that sounds familiar, talk with your doctor about which side and angle suit you. Anyone with shoulder injuries may find even a gentle wedge uncomfortable and may do better with an under-mattress wedge that keeps the sleeping surface flat.
What to look for when you buy
Long, wide memory foam wedge with gradual slope
Best for: Side sleepers with nighttime reflux
A long slope raises the head and upper back together, matching NIDDK's description of using a wedge under the head and upper back, while the width gives room to stay on your side.
Watch out: Takes up most of your half of the bed.
See options on AmazonWedge with arm or shoulder cutout
Best for: Side sleepers whose lower shoulder or arm goes numb
A cutout lets the lower shoulder sink, easing the shoulder pressure point the Sleep Foundation describes for side sleepers.
Watch out: Fixed cutout position may not match your build or your favorite side.
See options on AmazonUnder-mattress wedge
Best for: Side sleepers who keep rolling off a pillow wedge
It inclines the whole mattress, similar to Mayo Clinic's suggestion of a wedge between the mattress and box spring, so your normal side position stays unchanged.
Watch out: Tilts both sides of a shared mattress.
See options on AmazonHourglass knee pillow
Best for: Pairing with any wedge to keep hips level
Keeps the top leg from collapsing onto the lower one, which the Sleep Foundation says can twist the spine.
Watch out: Can slip away during the night unless it has a leg strap.

- Can you sleep on your side on a wedge pillow?
- Yes, if the wedge is long, wide and not too steep. Start the slope at your hips and use a regular pillow on top for your head.
- Which side should I sleep on with a wedge for acid reflux?
- Mayo Clinic suggests starting the night on your left side, and the Sleep Foundation notes evidence that left-side sleeping may help curb reflux.
- Do I still need a pillow on top of the wedge?
- Usually yes. Side sleepers need something to fill the space between the ear and the shoulder so the neck stays level.
- How high should a wedge be for side sleeping?
- For reflux, NIDDK describes raising the head 6 to 8 inches. Side sleepers often find a gentler, longer slope more comfortable than a short, tall one.
