What is the best pillow for acid reflux?

A wedge pillow providing 6–8 inches of upper-torso elevation is the gold standard for acid reflux. A 2011 study in the Journal of Gastrointestinal & Liver Disease recorded a 67% reduction in nighttime reflux events among GERD patients using a 28-degree wedge vs. flat sleeping. Our top picks are the MedCline Reflux Relief System and the Brentwood Home Zuma wedge.

Does sleeping on an incline help acid reflux?

Yes — substantially, when the incline is sufficient. Studies consistently show 6–8 inches of upper-torso elevation (or 28+ degrees) is required for measurable reflux reduction. Stacking standard pillows under the head does not work — it bends the neck and the abdomen remains flat, providing no anti-reflux benefit.

Should I sleep on my left or right side with acid reflux?

Left side. The lower esophageal sphincter sits above the gastric contents when sleeping on the left, which mechanically reduces reflux events. Right-side sleeping positions the sphincter below the gastric contents and frequently increases reflux. Multiple manometry studies confirm this asymmetric effect.

Q: How high should a wedge pillow be for acid reflux?

6–8 inches of elevation, or roughly 28–35 degrees of incline. Lower elevations (3–4 inches) provide minimal measurable benefit; higher elevations (over 10 inches) tend to cause the body to slide downward during sleep, which negates the anti-reflux effect. The 6–8 inch range is the documented therapeutic sweet spot.

Nighttime acid reflux affects over 60 million Americans. Elevating your upper body 6-8 inches is one of the most effective non-medication treatments — and the right pillow makes all the difference.

What to Look for in an Acid Reflux Pillow

Gradual Incline

A gradual slope (6-10 inches) keeps stomach acid from traveling up the esophagus without bending you at the waist

Longer wedges prevent sliding

Left-Side Support

Sleeping on your left side with elevation is the gold standard for reflux — gravity and anatomy work together

Medically recommended position

Firm Support

Soft pillows compress and lose elevation overnight. Firm foam maintains the therapeutic angle all night

Look for high-density foam

💡 Expert Tip: Don't stack regular pillows — they bend you at the waist and can actually worsen reflux by increasing abdominal pressure. A proper wedge pillow elevates your entire torso from the hips up.

Acid Reflux Pillow FAQ

How high should a wedge pillow be for acid reflux?

Gastroenterologists recommend elevating your head and torso 6-8 inches above your stomach. This is enough to use gravity to keep stomach acid from rising into your esophagus. Most effective wedge pillows are 7-12 inches tall.

Can a wedge pillow replace acid reflux medication?

For mild to moderate reflux, a wedge pillow combined with lifestyle changes (eating earlier, avoiding trigger foods) can significantly reduce or eliminate the need for medication. However, always consult your doctor before stopping prescribed medication.

Why is sleeping on the left side better for acid reflux?

Anatomy plays a key role. When you lie on your left side, your stomach sits below your esophageal sphincter, making it harder for acid to escape. On your right side, the stomach is above the sphincter, and acid flows more easily upward.

Do wedge pillows work for pregnancy-related reflux?

Yes, wedge pillows are one of the safest and most effective solutions for pregnancy-related acid reflux since many medications aren't recommended during pregnancy. The MedCline system is particularly good for pregnant women who need left-side positioning.
