The short version: a bed wedge raises your entire upper body on a gentle slope, which is a different thing from stacking pillows behind your head: stacking bends you at the neck, a wedge inclines you from the waist up. Raising the whole upper body is also what the NIH's NIDDK recommends for reflux, which is to raise the head of the bed rather than the head itself. The height most owners settle on for overnight use is around 7.5 inches. The other standard advice from the NIDDK is not to eat in the two to three hours before lying down. Our pick is the Kolbs 7.5 inch wedge, which pairs that height with a memory foam top layer so it is actually sleepable. Take the InteVision two-piece if you slide down, the extra wide Kolbs if you roll off, and the foldable InteVision if the wedge needs to disappear during the day.
This is not medical advice. A wedge changes the angle you lie at; it does not diagnose or treat anything. Persistent heartburn, symptoms that wake you regularly, difficulty swallowing, or any new digestive symptom should be discussed with a doctor. Everything below describes what these products are designed to do and what owners report.
Top Picks at a Glance
Our #1 Pick: Kolbs 7.5 Inch Bed Wedge Pillow
Two things separate a wedge people keep using from one that ends up in a closet: the height, and whether the surface is tolerable to lie on for eight hours. Kolbs gets both right. The 7.5 inch incline is the figure the category has largely converged on for overnight use — meaningful elevation without the steepness that makes people slide — and the construction puts a memory foam layer on top of a firmer support foam base, which is the difference between an incline and a ramp made of concrete.
The jacquard cover unzips and washes, which matters on an item that sits under your torso every night, and the finish is deliberately domestic rather than clinical — a small thing that turns out to matter, because owners report that a wedge which looks like hospital equipment gets removed whenever guests visit and then never goes back. The honest limitations are the ones every wedge shares. You may slide down it, particularly if you also sleep on your side. It is a large object that lives on the bed and has nowhere convenient to go by day. Foam under your torso is warm. And it takes most people one to two weeks to adapt to sleeping on a slope at all.
The Ranked Field
Best for most people who want the head of the bed raised at night
- 7.5 in height, standard bed width
- Memory foam top layer over support foam
- Removable jacquard cover
- Machine-washable cover
Why buy it: a wedge raises your whole upper body on an incline rather than just propping your head, which is what stops the neck kinking.
Best for people who slide down the wedge or want extra head support
- 7.5 in wedge plus a matching headrest pillow
- 2 in memory foam top layer
- Fitted cover included
- Standard 26 x 25 in footprint
Why buy it: the separate headrest fills the gap between the wedge and your head, which is the difference between sleeping on an incline and sleeping folded.
Best for restless sleepers who roll off a standard wedge
- 31 in wide by 33 in long
- 7.5 in incline height
- Memory foam top with jacquard cover
- Washable cover
Why buy it: a standard wedge is barely wider than your shoulders, so any turning during the night puts one shoulder off the edge.
Best for the most comfortable version of the whole arrangement
- Extra large 33 x 30.5 in wedge
- 2 in memory foam top layer
- Egyptian cotton cover
- Matching headrest pillow included
Why buy it: width, a memory foam top and a cotton cover together fix the three things people dislike about cheap wedges.
Best for travel, recovery and storing it during the day
- Folds for storage and transport
- 6.5 in incline with headrest
- Carrying case included
- Memory foam construction
Why buy it: a rigid wedge dominates a bed all day — one that folds into a case is the version people actually keep using.
Best for trying an incline before spending more
- 7.5 in incline height
- 1.5 in memory foam top layer
- Breathable stay-cool cover
- 25 x 26 in standard size
Why buy it: the cheapest way to find out whether sleeping on an incline suits you, which is the question worth answering first.

How We Rank
We never sleep on these wedges, and on a health-adjacent product we would rather be plain about that than imply otherwise. The ranking is built from aggregated owner ratings, weighted toward reviews written a month or more after purchase — because the first week on a wedge is uncomfortable for almost everyone, and the useful signal is who was still using it later. Four factors carry the weight. Incline height, and whether it is aimed at sleeping or sitting up. Surface comfort, meaning whether there is a memory foam layer over the support foam. Footprint, since narrow wedges are easy to roll off. And rating strength against review volume. Prices were checked at the time of writing. Full method: how we rank.
The Wedges, Reviewed
1. Kolbs 7.5 Inch — Best Overall
Covered above. Owners praise: a comfortable incline that is actually sleepable, a memory foam top layer, a washable domestic-looking cover, and solid construction. Owners gripe about: sliding down during the night, heat, bulk on the bed, and an adjustment period. Check price.
2. InteVision Wedge and Headrest Set — Best Two-Piece
The most common complaint about wedges is sliding, and the second is that your head ends up at an awkward angle at the top of the slope. A separate headrest pillow addresses both by filling the space above the wedge, so the incline continues rather than ending abruptly under your shoulders. InteVision has been making this two-piece arrangement for years and it is the configuration most owners with persistent sliding end up with.
Owners praise: the headrest completing the incline, less sliding, a 2 inch memory foam top, and a fitted cover. Owners gripe about: the two pieces separating during the night, bulk, heat, and a firm base foam. Check price.
3. Kolbs Extra Wide — Best Wide
A standard wedge is around 25 inches wide, which is barely more than a pair of shoulders. Turn once in the night and one shoulder is over the edge. At 31 by 33 inches, this version gives you room to move, which matters for anyone who does not lie perfectly still on their back. Same 7.5 inch height and memory foam top as the standard Kolbs.
Owners praise: genuine room to turn, the same comfortable incline, a washable jacquard cover, and stability. Owners gripe about: taking up most of a single bed, weight, heat, and the price over the standard version. Check price.
4. InteVision Extra Large with Egyptian Cotton — Premium Pick
This combines everything that addresses the standard complaints: extra large footprint so you cannot roll off, a matching headrest so you do not slide, a 2 inch memory foam top so it is comfortable, and an Egyptian cotton cover so it breathes better than the usual polyester. If you have already tried a cheap wedge and abandoned it, this is the version that answers why.
Owners praise: comfort well beyond basic wedges, a cotton cover that breathes, room to move, and the headrest. Owners gripe about: the price, considerable size on a shared bed, and weight when moving it. Check price.
5. InteVision Foldable — Best Portable
The practical objection to a wedge is that it lives on the bed permanently and looks it. This one folds and comes with a carrying case, so it can be put away in the morning or taken on a trip — which matters if you only need it during a flare-up or a recovery period. The incline is slightly gentler at 6.5 inches, and it includes a headrest.
Owners praise: folding away neatly, the carrying case, being genuinely travel-friendly, and the included headrest. Owners gripe about: a lower incline than fixed wedges, the fold line being noticeable under you, and the price for a portable item. Check price.
6. 7.5 Inch Value Wedge with Stay Cool Cover — Best Value
Sleeping on an incline is a genuine adjustment and not everyone takes to it, which makes a cheap first wedge a rational purchase. This one has the standard 7.5 inch height, a 1.5 inch memory foam top layer so it is not solid support foam, and a breathable cover. It is narrower and less refined than the premium options, but it answers the question of whether an incline suits you.
Owners praise: the price, a usable incline, a breathable cover, and a memory foam top at this level. Owners gripe about: a narrow footprint, sliding, firmness compared with thicker memory foam tops, and a cover that fits loosely. Check price.
What Owners Actually Complain About
Sliding down is the dominant complaint and it has three fixes: a headrest pillow to complete the incline, a knee wedge or a pillow under the knees to stop the body creeping downhill, and a sheet stretched over the wedge so there is friction rather than a slippery cover.
Firmness is the second, and it is a construction issue. Support foam alone is hard. A wedge with a memory foam layer on top is a different object to lie on, and it is worth paying the small premium for.
Width catches out anyone who moves in their sleep. Measure your shoulders and add room to turn; the extra wide versions exist for good reason.
Heat and bulk are inherent. A large foam block under your torso insulates, and it occupies the bed all day. A breathable cover helps with the first, and a foldable wedge with the second. Pairing a wedge with breathable sheets makes a noticeable difference — see best cooling sheets.
How to Choose a Wedge Pillow
Pick height for the purpose. Around 7 to 8 inches for sleeping on an incline; 10 to 12 inches is for sitting up in bed and is too steep for most people overnight.
Insist on a memory foam top layer. Base foam alone is genuinely uncomfortable over eight hours, and it is the single most common reason a wedge gets abandoned.
Size the footprint to how much you move. Still sleepers can use a standard 25 inch width; anyone who turns should buy wide.
And consider the alternative. Risers under the head of the bed frame elevate your whole body on a continuous slope with nothing to slide off, and cost less than a wedge. A wedge wins when you share a bed with someone who does not want the mattress tilted.
The Verdict
The Kolbs 7.5 inch wedge is where we would start: the incline height the category has settled on, a memory foam top layer that makes it sleepable, and a cover that washes and does not look clinical. Take the InteVision two-piece if you slide, the extra wide Kolbs if you roll off, the InteVision extra large if you want the most comfortable version of all of it, and the foldable if it needs to disappear by day. And once more, plainly: this is a bedding page, not medical advice — talk to a clinician about persistent reflux symptoms. Check price on Amazon →
