Quick answer: a wedge pillow that lifts your whole upper body, so your head ends up about 6 to 8 inches higher, may reduce nighttime acid reflux symptoms, which is why both the NIDDK and the American College of Gastroenterology list raising the head of the bed as an option. Our top pick is the Kolbs 7.5-inch memory foam wedge, but a wedge only eases symptoms, it does not treat GERD. Heartburn more than twice a week, or reflux with trouble swallowing, vomiting or weight loss, needs a doctor.

Read This Before You Buy a Wedge Pillow
Raising the upper body is one of the standard lifestyle suggestions for nighttime reflux, but the evidence behind it is modest. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) lists elevating your head during sleep, by placing a foam wedge or extra pillows under your head and upper back to raise your head 6 to 8 inches, among the lifestyle changes for gastroesophageal reflux disease (GERD). The American College of Gastroenterology’s 2022 guideline suggests elevating the head of the bed for nighttime GERD symptoms, and labels that a conditional recommendation based on low-quality evidence. The idea is simple: gravity helps keep stomach contents down when you are tilted rather than flat.
The same guideline also suggests avoiding meals within 2 to 3 hours of bedtime, which matters at least as much as the pillow. For why reflux gets worse when you lie down and what else helps, see our guide to why acid reflux gets worse at night.
Shape matters. NIDDK says pillows can work if they lift your upper back as well as your head, but loose pillows shift and flatten overnight, so a firm wedge is easier to keep at a steady angle (that last point is our view, not a research finding). Sleep Foundation says a wedge that extends from the head toward the hips, keeping the whole upper body elevated, may be most beneficial, and that you should consult a doctor if medical issues interrupt your sleep.
A wedge does not address why reflux is happening, such as large or late meals, trigger foods or alcohol. It is not a substitute for medical evaluation if reflux is frequent or comes with warning signs, which are listed in the doctor section below.
Who This Is For
This guide is aimed at people dealing with a specific kind of problem, not everyone who occasionally gets heartburn.
- You get nighttime heartburn or acid reflux that disrupts your sleep, rather than reflux that’s only a daytime issue.
- You’ve noticed lying flat makes symptoms worse, especially after eating close to bedtime.
- You’ve tried stacking regular pillows and found they don’t hold an incline, or they just bend your neck instead of lifting your torso.
- You want a gravity-based, non-medication approach to try on its own or alongside other reflux management.
- This isn’t a fit if your reflux is frequent, severe, or comes with difficulty swallowing, persistent vomiting, weight loss or chest pain. That needs a doctor’s evaluation, not just a wedge.
Quick Recommendations
If you don’t need the full breakdown, here’s how our picks below stack up:
- Best Overall: Kolbs Wedge Pillow for Acid Reflux: a 7.5-inch memory foam wedge that sits inside the 6 to 8 inch range NIDDK describes.
- Best Budget: 10 Inch Wedge Pillow for Acid Reflux Relief: a taller, steeper 10-inch triangle wedge. Check the listing for the current price.
- Best Premium: Avana Contoured Bed Wedge With Cooling Cover: gel-infused memory foam with a cooling Tencel cover, for anyone who also sleeps hot.
How We Chose
How we picked these: we focused on height and incline (checked against the 6 to 8 inch range NIDDK describes), material support (memory foam generally holds its shape better than basic foam), cover quality and washability, and how the listing describes the product. Each pick also carries a rating out of 10, scored against the specific need named in its heading using manufacturer and retailer listings and patterns across buyer reviews.
We don’t take payment for placement in this list, and picks get swapped out if a better option comes along or a listing goes stale. Product details come from listing summaries and the maker’s or other retailers’ pages, and we do not quote prices, so use the links to check the current price and size.
What to Look For
Height and incline
NIDDK’s 6 to 8 inch figure describes how far your head is raised, so a wedge in roughly that range is the sensible target. We found no evidence that taller is better, and a very steep wedge can strain the neck or make you slide down, so more height is not automatically more relief. Low wedges of a few inches are better suited to leg elevation.
Foam quality and durability
A memory foam top over a firm base is the usual design for wedges meant to be slept on. Softer, low-density foam can compress over time, which lowers the incline you bought it for.
Cover and width
A removable, washable cover matters for hygiene over time, and a wider wedge keeps you supported if you shift position during the night rather than sliding off the incline. If you also sleep on your side, our guide to the best sleeping position covers the trade-offs.

Prices change often, so use the links to check current price and size.
Kolbs Wedge Pillow for Acid Reflux: Best Overall
Rating: 9.0/10
Check the latest price and availability on Amazon
What it is: A 7.5-inch bed wedge with a memory foam top and a jacquard cover, listed for acid reflux, sleep apnea and back pain relief. Kolbs also sells an extra-wide version.
Why we recommend it: Its 7.5-inch height sits within the 6 to 8 inch range NIDDK describes, and it is a straightforward wedge shape with a memory foam top rather than a gimmicky design.
Pros: A height that is in the range the guidance describes without feeling extreme; a memory foam top; an extra-wide option if you move around.
Cons: The standard width may feel narrow if you shift a lot, and it is firmer than a regular pillow, which takes some adjustment; check the listing for the current price and whether the cover is washable.
Best for: Anyone wanting a reflux-oriented wedge in the recommended height range without overthinking it.
10 Inch Wedge Pillow for Acid Reflux Relief: Best Budget
Rating: 8.3/10
See the current details on Amazon
What it is: A 10-inch triangle wedge sold under the Bedluxe name, with a listing title that says it is for acid reflux relief, sleeping, back pain and snoring. Check the listing for the foam type, cover and price, which we do not state here.
Why we recommend it: It is the taller, steeper option here, for readers who find a lower wedge does not give enough lift. Check the current price to see whether it fits your budget.
Pros: A taller incline than the Kolbs wedge; a simple triangle shape.
Cons: At 10 inches it is above the 6 to 8 inch range NIDDK describes, and a steeper incline takes more adjustment and may not suit everyone; confirm the foam quality on the listing before buying.
Best for: Readers who want the highest incline in this list and are happy to confirm the foam and price on the listing.
Avana Contoured Bed Wedge With Cooling Cover: Best Premium
Rating: 8.7/10
What it is: A contoured bed wedge with gel-infused memory foam and a cooling Tencel cover, listed on Amazon in a 24-inch width. A Walmart listing for the Avana contoured wedge gives dimensions of 35 by 24 by 8 inches, a polyurethane foam base with a gel-infused memory foam top, and a removable, machine-washable cover. Avana’s own site notes the product is meant to promote comfortable positioning and is not intended to diagnose, treat, cure or prevent any disease.
Why we recommend it: Its gel-infused foam and cooling Tencel cover address the heat a standard foam wedge can hold, and the contoured shape is designed for side sleepers.
Pros: A cooling cover that helps if you sleep hot; a washable cover; at 8 inches it sits in the 6 to 8 inch range.
Cons: Check the listing for the current price; the contoured shape may not suit everyone’s preferred position.
Best for: Hot sleepers and side sleepers who want a contoured shape.
Comparison Guidance
All three picks above are built to raise your upper body. Here’s how to choose between them:
- You want a straightforward wedge in the recommended height range: the Kolbs Wedge Pillow.
- You want a taller incline and will check the price and foam first: the 10 Inch Wedge Pillow.
- You sleep hot or on your side as well as dealing with reflux: the Avana Contoured Bed Wedge, for its cooling cover and contoured shape.
Common Buying Mistakes
- Buying a very low wedge. A wedge of only a few inches is built for leg elevation and will not lift you into the range the guidance describes.
- Assuming taller is better. NIDDK’s range is 6 to 8 inches. We found no evidence that going higher helps more, and a very steep wedge can be uncomfortable.
- Choosing very soft foam. Soft foam can compress over time, quietly losing the incline you bought it for.
- Ignoring the cover and width. A non-washable cover becomes a hygiene problem over time, and a narrow wedge lets you slide off the incline if you shift position during the night.
- Treating a wedge as a full fix. It is a symptom aid based on elevation, not a treatment for whatever is causing the reflux, and it does nothing about late meals.
When to See a Doctor Instead of Relying on a Pillow
Mayo Clinic advises making an appointment if heartburn occurs more than twice a week, if symptoms persist despite non-prescription medicines, or if you have difficulty swallowing, persistent nausea or vomiting, or weight loss because of poor appetite or difficulty eating. It also says to seek help right away for severe chest pain or pressure, especially with pain in the arm or jaw or difficulty breathing (Mayo Clinic: heartburn). The American College of Gastroenterology recommends endoscopy as the first test for people with difficulty swallowing or other alarm symptoms such as weight loss and gastrointestinal bleeding. NIDDK adds that if your symptoms will not go away with over-the-counter medicines, you should talk with your doctor. A wedge should not delay any of that.
If a dry or irritated throat is your main symptom, our guide to why your throat gets dry even when you breathe through your nose covers reflux alongside other possible causes.
Frequently Asked Questions
What is the best pillow for acid reflux?
A wedge pillow that raises your whole upper body is the usual choice, and our top pick is the Kolbs 7.5-inch memory foam wedge. Aim for a lift of roughly 6 to 8 inches, the range NIDDK describes, and check the current price and size before buying.
Does a wedge pillow help with acid reflux?
It may reduce nighttime symptoms for some people. The American College of Gastroenterology suggests elevating the head of the bed for nighttime GERD symptoms, but rates the evidence as low quality, and a wedge does not treat GERD itself.
How high should a wedge pillow be for acid reflux?
NIDDK describes raising your head 6 to 8 inches using a foam wedge or extra pillows under your head and upper back. We found no evidence that a taller wedge works better, so there is no need to go above that range.
Can I use a wedge pillow if I sleep on my side?
Many people do, and some wedges are designed for side sleepers, such as the contoured Avana. Wider models tend to be more comfortable if you shift positions during the night.
When should reflux be checked by a doctor instead of managed with a pillow?
See a doctor if heartburn happens more than twice a week, persists despite non-prescription medicines, or comes with difficulty swallowing, persistent vomiting or weight loss. Seek help right away for severe chest pain or pressure, especially with pain in the arm or jaw or difficulty breathing.
What This Product Cannot Fix
A wedge pillow uses gravity to make it harder for stomach acid to travel up the esophagus, but it doesn’t address why reflux is happening in the first place, such as large or late meals, trigger foods or alcohol. It’s a symptom aid built on elevation, not a treatment for GERD or any underlying condition. Frequent reflux, or reflux with difficulty swallowing, persistent vomiting, weight loss or chest pain, needs a doctor’s evaluation rather than pillow-based management alone.
Key Takeaways
Raising your upper body about 6 to 8 inches is a recognized lifestyle option for nighttime reflux, though the supporting evidence is low quality. The Kolbs wedge is our best all-around choice, the 10 Inch Wedge is the tallest option, and the Avana cooling wedge suits hot or side sleepers. Heartburn more than twice a week, or any difficulty swallowing, persistent vomiting, weight loss or severe chest pain, means seeing a doctor rather than relying on elevation alone.
