Bed wedge pillow: which height and width to choose

Who needs a bed wedge pillow?

A wedge is a single block of foam that slopes from a low front edge to a high back. It raises the head, shoulders and upper back together, rather than bending the neck forward as a stack of pillows can.

People use wedges for reading or watching TV in bed, for resting after a hospital stay, and when a clinician has suggested sleeping with the upper body raised. A wedge costs far less than an adjustable bed base and moves easily between rooms.

It is a fixed shape, though. If you want to change the angle during the night, or to raise your knees as well, an adjustable base may suit better.

• Reading, TV or resting upright in bed
• Recovery periods when lying flat is uncomfortable
• A clinician's suggestion to sleep with the upper body raised
• Guest rooms or travel, where a bed base cannot change
• People who share a bed and want their own side raised

Wedge pillow for acid reflux: what public health sources say

NIDDK, part of the US National Institutes of Health, lists raising the head during sleep as a lifestyle step for reflux, using a foam wedge or extra pillows under the head and upper back to lift the head 6 to 8 inches off the bed.

The UK's NHS suggests raising the head of the bed itself by about 10 to 20 cm (4 to 8 inches) so the chest and head are above the waist. It cautions against using extra pillows to get the same effect, because that can increase pressure on the belly.

The two sources agree that the whole upper body should be lifted, not just the head. Neither is a reason to skip medical advice: frequent heartburn, trouble swallowing or weight loss need a doctor's review.

• Lift the head and upper back together, not only the head
• NIDDK: 6 to 8 inches, using a wedge or pillows under the upper body
• NHS: raise the bed head 10 to 20 cm (4 to 8 in) and avoid stacked pillows
• See a doctor if symptoms are frequent or not improving

What height and width of wedge pillow do you need?

Measure the width of your side of the mattress. A wedge narrower than your shoulders feels unstable, while one wider than your half of a shared bed pushes into your partner's space.

Then check the length. A longer wedge gives a gentler slope for the same height, and it reaches further down the back, which may feel more comfortable for sleeping than a short, steep one.

Finally, think about your pillow. Some people sleep with their usual pillow on top of the wedge, especially side sleepers, so allow for that in the total height. The pillow should keep your neck in line rather than bent forward, the same check used for pillow height for neck pain.

• Width of your half of the mattress
• Wedge height, length and the slope they create
• Whether your usual pillow will sit on top
• Headboard gap, so the wedge does not slide back
• Room to store the wedge if it is not used every night

Wedge pillow vs bed risers vs adjustable base

Only one wedge passed our listing and maker-page checks. The table sets the Sleepnitez wedge beside the two simplest alternatives. Compare the published dimensions with your own measurements before ordering, since a fixed wedge cannot be adjusted once it arrives.

Think about the bed you share, too. A 25-inch (64 cm) wedge takes up most of one side of a queen mattress, so a partner who sleeps flat keeps their own space. On a twin bed it covers most of the width, and on a full bed nearly half.

Setup, sliding and care

New foam wedges often arrive compressed. Give the wedge time to expand fully in a ventilated room before judging the height or firmness.

Many people slide down a wedge during the night. Placing it tight against the headboard and adding a pillow under the knees can help, and so can a slightly lower wedge.

Wash the cover as the label says, and keep the foam itself dry. A spare cover makes laundry day easier.

• Let the foam expand fully before the first night
• Push the wedge against the headboard
• A pillow under the knees may reduce sliding
• Wash only the removable cover, as labeled

When to ask for personal advice

If the incline is for reflux, breathing, a heart or lung condition, or recovery after surgery, ask the clinician treating you which height and setup they recommend. They may prefer a raised bed head to a wedge.

An occupational therapist can help if getting in and out of bed with a wedge, or reaching the bedside table from a higher position, has become difficult.

Bring the details of the wedge or the bed setup you are considering to the appointment. A clinician can then tell you whether its height and shape match what they have in mind, which is easier than describing a product from memory.

• Heartburn most days, or symptoms that keep returning
• Trouble swallowing, vomiting or weight loss
• Breathing problems when lying flat
• Back, hip or shoulder pain that a wedge seems to worsen
• Getting in and out of bed has become harder with the wedge in place
