Wedges for beds: types, heights and how to choose
Wedges for beds come in two main forms. One is a foam wedge pillow that sits on top of the mattress and props up your upper body (or your legs). The other is an under-mattress wedge, or a set of risers, that tilts the whole bed. For reflux, snoring or reading in bed, most people start with a foam wedge pillow because it costs less, moves between rooms and leaves the bed as it is. If you share a bed, sleep on your side or keep sliding down a wedge at night, raising the whole mattress usually works better.
The main types of bed wedges
The word "wedge" covers products that solve quite different problems, so it helps to know which one you are shopping for.
| Type | What it raises | Good for | Trade-offs |
|---|---|---|---|
| Foam wedge pillow | Head, shoulders and chest | Reflux, snoring, reading, watching TV, back sleepers | You can slide down it; covers one side of the bed only; needs storage space |
| Leg or knee wedge | Legs and knees | Easing pressure on the lower back when lying face up, resting tired legs | Mostly a back-sleeping position |
| Under-mattress wedge | The top section of the mattress | An incline with no lump under you; side sleepers | Works best with flexible foam mattresses; tilts a partner too unless the bed is split |
| Bed risers or blocks | The whole bed frame at the head end | A gentle full-body slope | Bedding and pillows drift downhill; the frame has to be stable on blocks |
| Adjustable base | Head and foot sections, at the push of a button | People who change position often or read in bed nightly | By far the biggest purchase; may need a compatible mattress |
| Gap-filler wedge | Nothing; it fills the space between mattress and headboard | Pillows falling behind the bed | A different problem entirely |
What to check before you buy a wedge pillow
Height and angle
Height decides how steep the slope is. Wedges sold for sleeping commonly run from about 7 to 12 inches tall. A lower wedge feels like a gentle hill and is easier to sleep on all night. A taller one puts you closer to sitting up, which is great for a book and harder to sleep on until you are used to it. If a doctor has given you a specific elevation to aim for, measure at the height of your head and buy to match.
Length, and where the slope starts
This gets less attention than height, but it changes how the wedge feels. A long wedge starts its slope near your waist, so your chest and stomach rise along with your head. A short, steep wedge only lifts your head and shoulders, which bends you at the neck in much the same way as stacking three pillows. If the reason you want a wedge is reflux, the goal is to keep your whole torso raised, so a slope that begins low on your back matters.
Firmness and the top layer
The base foam needs to be firm enough to hold the angle under your shoulders. Too soft and it flattens where you weigh the most, leaving you lower than you paid for. Many wedges add a softer memory foam layer on top so the surface feels less like a ramp.
Heat
Foam holds warmth, and on a wedge your whole back is pressed into it for hours. If you run hot, look for a cooling layer or a cover made to move heat and moisture away from your skin.
The cover
A removable, washable cover is close to essential. A wedge is too bulky to clean any other way.
Your sleep position
Back sleepers have the easiest time on a foam wedge. Side sleepers can use one, but the sloped surface is firm under the shoulder and the body tends to roll or slide, so an under-mattress wedge or risers often suit them better. Stomach sleeping on an incline arches the lower back, and most stomach sleepers give up on wedges quickly.
Who each option suits
- If you want to try sleeping elevated without changing your bed, a foam wedge pillow is the cheapest test, and it doubles as a backrest for reading.
- Couples where only one person wants the incline should use a wedge pillow on that side. Risers and most under-mattress wedges tilt both of you.
- Side sleepers who need elevation every night are usually more comfortable on an under-mattress wedge or an adjustable base, because the mattress keeps its normal softness.
- A leg wedge makes sense for people who lie on their back and want their knees bent and supported, or who like to rest their legs up in the evening.
- Pillows disappearing behind the headboard? That is a gap filler, not an elevation wedge.
One case where no wedge helps: if your back aches because the mattress sags in the middle, raising one end won't fix the dip. A mattress topper or a new mattress is the better place to start.
Where Dosaze fits (and where it doesn't)
Dosaze makes one foam wedge, the Therapeutic Cooling Wedge Pillow. It was designed by ergonomists to promote good sleep posture in an elevated position. It is CertiPUR-US Certified memory foam with a cooling gel layer, and the cover uses a nanoporous fabric that wicks heat and moisture away from your body. The cover comes off for washing. We describe it as great for reducing acid reflux and GERD symptoms, and it is also built for people who snore or want to sleep at an angle. You can turn it around as a backrest for lounging, or slide it under your legs for some lumbar relief.
If you want neck support on top of the incline, the Alignment Kit pairs the wedge with our Contoured Orthopedic Pillow, a memory foam pillow shaped to the curve of the neck to promote spinal alignment.
Where we don't fit: Dosaze doesn't sell under-mattress wedges, bed risers, adjustable bases or gap fillers. If you are a committed side sleeper who wants the whole mattress tilted, one of those is likely the better buy. And if you are dealing with sleep apnea, talk to your doctor first. A wedge can be part of how you sleep, but it is not a replacement for treatment you have been prescribed.
You can browse the rest of our pillows to see what pairs with a wedge, and our FAQ covers the 60-night sleep trial, shipping and returns.
Getting used to sleeping on a wedge
- Drop your usual pillow, or swap to a thin one. A full pillow on top of a wedge pushes your chin toward your chest.
- If you slide down during the night, put a pillow or a leg wedge under your knees. Bent knees act like a brake.
- Line the bottom edge of the wedge up with your waist rather than leaving a gap below it, so the slope supports your lower back.
- Expect the first few nights to feel strange. Sleeping at an angle is a new position for most people, and it takes some adjusting.
Frequently asked questions
Is a wedge pillow better than stacking regular pillows?
For elevation, usually yes. Stacked pillows lift your head and bend your neck forward, and they shift apart during the night. A wedge gives a steady slope that starts lower on your back, so your chest rises along with your head.
What height wedge pillow should I get?
Wedges for sleeping commonly range from about 7 to 12 inches. Lower wedges are easier to sleep on all night, while taller ones are better for reading or sitting up. If a doctor has suggested a specific elevation, measure at your head and pick a wedge that matches, and check that the slope starts near your waist.
Can you sleep on your side on a wedge pillow?
You can, but many side sleepers find the firm slope uncomfortable under the shoulder and tend to roll or slide. A thin pillow for the head and a pillow under the knees can help. If side sleeping on a wedge never feels right, an under-mattress wedge or bed risers keep the mattress surface soft while still raising you.
Do under-mattress wedges work with every mattress?
They tend to work best with flexible foam mattresses that bend over the slope. Thick innerspring or hybrid mattresses can resist bending and leave a gap or an uneven incline. Check the wedge maker's guidance on mattress type and thickness before buying.
Will a bed wedge raise my partner's side too?
A foam wedge pillow only raises the person lying on it. Bed risers and most under-mattress wedges tilt the whole mattress, so both of you sleep at an angle unless you have a split mattress or a split adjustable base.
