Wedge Pillow Guide: Angles, Heights and Which Shape to Buy
Share
Calm Eden Sleep Journal · Updated October 5, 2026
For sleeping, choose a wedge about 15–20 cm (6–8 in) high with a gentle 10–30° incline that raises your whole torso. For reading or TV, a taller backrest of 25–35 cm (10–14 in) at 30–45° fits. For legs, use a leg-elevation wedge. Unsure? Choose an adjustable wedge.
A wedge pillow is a triangle of firm foam (or an inflatable version) that holds you at an incline. Unlike stacking pillows — which compress, slide and leave your neck bent — a wedge keeps a consistent angle from the lower back up. People use them for four main jobs: sleeping slightly raised, sitting up in bed, raising the legs, and staying on their side.
Pick the angle for the job
| Use | Typical incline | Typical height | Notes |
|---|---|---|---|
| Sleeping raised (e.g. nighttime heartburn) | ~10–30° | 15–25 cm (6–10 in) | The wedge should start under the lower back so the whole torso is raised, not just the head. |
| Reading, TV, laptop in bed | 30–45° | 25–35 cm (10–14 in) | A backrest shape with a flat top edge supports the upper back. |
| Leg elevation | Gradual slope | Varies | Supports calves and knees along the length, not just the heels. |
| Staying on your side | Small wedge behind the back | Low | Stops you rolling onto your back. |
Fixed foam vs adjustable vs inflatable
- Fixed foam wedges are simple and stable. Higher-density foam holds its angle longer; soft foam can flatten over time.
- Adjustable wedges are made of sections or inserts you rearrange, so one product can go from a low sleeping slope to a reading angle or a leg rest.
- Inflatable wedges pack down for travel and let you control firmness with air, at the cost of a slightly less solid feel.
- Backrest wedges are taller and more upright — built for sitting rather than sleeping.
Sizing a wedge to your bed
Measure the width of your side of the bed. Most sleep wedges are 50–65 cm (20–26 in) wide, similar to a pillow, which leaves room for a partner. If you use one for sitting up or to close a gap between the mattress and headboard, match the width to your mattress size instead. Check the length too: a longer slope starts lower on your back and feels less like being folded in half.
Side sleeping on a wedge
Side sleepers can use a gentle wedge, but a steep one tends to push the shoulder up and slide you down the slope. Two practical options:
- Keep the incline low and use a regular side-sleeper pillow on top of the wedge for head height.
- Use a small anti-roll wedge behind your lower back to hold the side position without raising your torso.
For head height on top of a wedge, see our side-sleeper pillow height guide. On nights you sleep flat again, a contoured head pillow such as the two-sided Amity Comfort Cervical Pillow lets you try a contoured face and a hollow face on your own mattress.
Getting comfortable in the first nights
- Place the bottom edge of the wedge at your lower back, not under your shoulders.
- Put a pillow or rolled towel under your knees to stop sliding down.
- Start with the lowest setting and work up.
- Expect a few nights of adjustment — sleeping on an incline feels different.

Facts come from each product listing; we have not lab-tested these wedges. The Slope listing does not state a height, so check its photos against your bed before choosing.
Reading the table: for sleeping raised, Summit (27 cm, 30°) sits at the steep end of the sleeping range, and Talus lets you start lower and add height. Ridge is a sitting-up backrest rather than a sleeping wedge, Buoy is for the legs, Harbor is for staying on your side, and Lift is the one to pack for travel.

Care and lifespan
Foam wedges usually have a removable cover; wash it as directed and air the foam. Replace a wedge when it no longer holds its angle or the top edge has softened noticeably.
Frequently asked questions
What height wedge pillow should I get?
For sleeping raised, most people start around 15–20 cm (6–8 in). For sitting up to read or watch TV, 25–35 cm (10–14 in) is more usual. If you are unsure or share the bed, an adjustable wedge lets you try several heights.
What angle wedge pillow is best for sleeping?
Most people find a gentle incline — roughly 10–30°, or 15–25 cm (6–10 in) at the high end — comfortable for sleeping. Steeper wedges suit sitting up rather than sleeping.
Can you sleep on your side on a wedge pillow?
Yes, on a low incline. Add a regular pillow on top for head height, and a pillow under the knees helps stop you sliding. Steep wedges are harder for side sleepers.
Is a wedge pillow better than stacking pillows?
Usually. Stacked pillows compress and shift, and they tend to bend the neck rather than raise the whole torso. A wedge keeps a consistent angle from the lower back.
How do I stop sliding down a wedge pillow?
Place the wedge's lower edge at your lower back and put a pillow or rolled towel under your knees. A lower incline also reduces sliding.
Can a wedge pillow help with snoring?
Some people notice they snore mostly when lying flat on their back, so they try sleeping raised or on their side. A wedge is a comfort product, not a snoring treatment. Loud snoring with gasping, choking or daytime sleepiness can be a sign of sleep apnea and should be checked by a doctor.
Can you sleep on a wedge pillow every night?
Many people use one nightly. Start on a low incline, put the lower edge at your lower back and add a pillow under your knees so you don't slide. If you have a medical condition, ask your doctor which sleeping position suits you.
Can I return a wedge pillow after using it?
Yes. Calm Eden orders come with a 30-day risk-free trial from delivery, and opened and used items are accepted. Change-of-mind return shipping is the customer's cost; see the refund policy for the full terms.
