Raise the head of your bed 6 to 9 inches using blocks under the legs or a wedge to ease nighttime GERD symptoms.
Nighttime heartburn is a different animal than daytime reflux. When you lie flat, stomach acid travels more easily up your esophagus, where it can linger for hours. Elevating the head of the bed works by using gravity to keep acid where it belongs, and the best beds for GERD often include features that make this positioning easier. The measure is a cornerstone of non-drug GERD management, though it works best when paired with other habits.
How Much Should You Raise the Bed?
Most major guidance settles on a consistent number: elevate the head end of the bed by roughly 6 to 9 inches (15 to 23 centimeters). This is the range recommended by the Mayo Clinic and cited in clinical guidance from the American College of Gastroenterology.
An Australian evidence summary for general practitioners offers a more graduated approach. Research in that review used a 20 cm elevation, but it suggests trying 10 cm first and increasing to 20 cm after a few weeks if symptoms don’t improve. That slower start helps your body adjust to the unfamiliar angle.
What’s the Best Way to Raise the Bed?
You have two solid options, and both beat the pillow-stacking approach. The Mayo Clinic recommends placing wood or cement blocks under the feet at the head end of the bed. If that isn’t practical, a wedge placed between the mattress and box spring works nearly as well.
Other workable tools include plastic or wooden bed risers, therapeutic wedge pillows, and inflatable mattress lifters. Some adjustable hospital-style beds handle elevation with a button.
Why Pillows Alone Usually Fail
The most common mistake is stacking pillows. That approach raises only your head and neck, bending your torso at the waist and actually increasing pressure on the stomach. The Mayo Clinic notes this strategy is usually not effective because it doesn’t elevate your torso enough to keep acid down.
Does Raising the Bed Actually Help?
Yes, for nighttime symptoms. The ACG guideline points to multiple studies, including randomized controlled trials, showing that head-of-bed elevation or sleeping on a wedge improves nocturnal GERD symptoms and reduces nighttime esophageal acid exposure.
The evidence has limits worth knowing. The ACG rates this recommendation as conditional with low-level evidence, and the AGA frames it for selected patients troubled by heartburn or regurgitation when lying down. So this is a targeted measure for people whose reflux flares at night, not a cure-all.
| Elevation Method | How It Works | Best For |
|---|---|---|
| Bed blocks or risers | Lift the entire head of the bed frame | Most people; most stable option |
| Wedge between mattress and box spring | Creates a gradual torso incline | Rental homes or when blocks aren’t possible |
| Therapeutic wedge pillow | Sits on top of the mattress | Travel or single-side adjustment |
| Inflatable mattress lifter | Fits under the mattress and inflates | Temporary setups or easy removal |
| Adjustable bed | Built-in head elevation | People who want variable angles |
Are There Any Downsides?
Elevating the bed is relatively safe for most people. The RACGP notes that adverse events are mostly minor, including varicose vein pain and the nuisance of slipping down the bed during the night. A body pillow at your back or a folded blanket under your knees can reduce the sliding problem.
If you have circulation issues in your legs, talk to your doctor before committing to a steep angle.
What Else Helps Nighttime Reflux?
Elevation works best as part of a broader nighttime routine. The Mayo Clinic advises not lying down for 2 to 3 hours after a meal, giving your stomach time to empty before you recline. When you do go to bed, start on your left side. Left-side sleeping keeps the lower esophageal sphincter above stomach contents, and research consistently shows less acid exposure on that side than on the right.
If you’re still waking with heartburn after a few weeks of consistent elevation, revisit your evening meals, medication timing, and whether you’re truly sleeping on an incline rather than just propped up on pillows.
FAQs
Can I just use extra pillows instead of raising the bed?
Extra pillows usually won’t work for GERD. Stacking pillows raises only your head and neck, which can increase stomach pressure and make reflux worse. The goal is a straight incline from hips to head, which requires lifting the mattress or bed frame itself.
Is it safe to sleep on an incline every night?
For most people, yes. Reported side effects are minor and include varicose vein discomfort and sliding down the bed. You can minimize sliding with a knee pillow or a non-slip mat under your mattress. People with leg circulation problems should check with a doctor first.
How fast will I notice a difference?
Some people notice within a few nights, but the Australian evidence summary suggests trying a 10 cm elevation for a few weeks before increasing to 20 cm. Give your body time to adjust and track your symptoms before deciding the angle isn’t working.
