Acid reflux (GERD) symptoms worsen when lying flat — gravity no longer keeps stomach acid from flowing back into the esophagus. A wedge pillow elevates the upper body at an angle that uses gravity to prevent this reflux throughout the night.
How Wedge Pillows Work for GERD
Elevating the head and torso 6–8 inches above the stomach creates a gravity gradient that significantly reduces nighttime reflux events. The Journal of Clinical Gastroenterology found that even 6-inch head elevation reduced nighttime GERD symptoms by 32% in study participants. A wedge pillow achieves this elevation without the awkwardness of propping pillows (which flatten and shift during sleep).

Key Specs to Look For
- Elevation angle: 30–45 degrees (7–8 inches) for GERD; 15–20 degrees for mild reflux or snoring
- Length: 24–26" minimum — short wedges only support the head, not the entire torso
- Width: Standard size (24") for solo use; full-size (48") for couple sharing
- Foam density: 4–5 lb/ft³ to support weight without compressing flat
- Cover: Washable, breathable cover
Top Wedge Pillow Picks for GERD
#1 — Medslant Acid Reflux Wedge Pillow
The most studied brand in clinical research. 32x30x7" high-density foam wedge specifically designed for GERD. Provides full upper body support rather than just head elevation. Washable microfiber cover. ~$80–100.
#2 — Avana Inclined Mattress Topper
A full-length incline wedge that runs the entire length of a twin, full, or queen mattress. Rather than a small wedge pillow, this creates a gentle whole-bed elevation — ideal for those who move during sleep. ~$150–200.
#3 — FitPlus Premium Wedge Pillow

4" base foam + 1.5" memory foam top layer. 26" x 25" x 7.5" dimensions. The memory foam top adds comfort to the firm wedge base. Machine-washable bamboo cover. ~$50–70. Best budget option.
Alternative: Adjustable Bed Base
For couples, a wedge pillow that only elevates one partner is impractical without a split king setup. An adjustable bed frame with independent head elevation provides the same GERD benefit with far more flexibility and comfort for both partners. Saatva's adjustable foundation includes precise degree settings for head elevation.
Lifestyle Changes That Help
Frequently asked questions about pillows
Our top pillow pick
The Saatva Pillow
Shredded Talalay latex core, removable fill, 45-night trial — the most adaptable pillow for multi-position sleepers. From $165.
How often should you replace your pillow?
Every 18–36 months depending on fill. Latex pillows last 5–7 years; solid memory foam 2–3; down 2–5 with fluffing. The fold test tells you: fold the pillow in half, let go — if it doesn't spring back, it's done. Saatva's pillow range covers all major fill types.
What's the best pillow loft by sleep position?
Side sleepers: 5"–7". Back sleepers: 3"–5". Stomach sleepers: 1"–3". Combination sleepers: 4"–5" adjustable-fill.
Are expensive pillows actually worth it?
Cost-per-year, yes — a $150 latex pillow over 6 years ($25/year) beats a $30 polyester pillow over 1 year ($30/year), plus you get better neck support the whole time.
- Stop eating 3 hours before bed
- Sleep on your left side (reduces reflux vs right side)
- Avoid tight waistbands and lying down after meals
- Elevate the head of your bed on risers (4–6 inches) as an alternative to wedge pillows
FAQ
How many inches should a wedge pillow be for acid reflux?
7–8 inches (approximately 30–45 degree angle) is the clinically studied elevation for GERD relief. Lower wedges (4–6 inches) help with mild reflux or snoring but may not fully address severe GERD symptoms.
Can I use regular pillows instead of a wedge for GERD?
Regular pillows aren't ideal — they only elevate the head without the torso, can cause neck strain, and flatten and shift during sleep. A properly sized wedge pillow provides consistent, full upper-body elevation throughout the night.
What sleeping position is best for acid reflux?
Left-side sleeping with upper body elevated is the best position for GERD. Left-side sleeping keeps stomach acid away from the esophageal junction by gravity. Combined with a wedge pillow or elevated head of bed, this is the most effective non-medication approach.
