A wedge pillow is a triangular foam support that elevates part of the body to address specific health conditions — acid reflux, sleep apnea, snoring, back pain, leg swelling, and post-surgery recovery. Unlike standard pillows, wedge pillows are designed for therapeutic positioning rather than general head support.
Types of Wedge Pillows
Upper Body Wedge (Incline Pillow)
The most common type — a long triangular ramp placed under the torso to elevate the upper body at 30–45°. Primary uses: acid reflux/GERD, snoring, sleep apnea supplemental therapy, post-surgery recovery, reading in bed. Typical size: 24–28" wide × 24" deep × 7–12" tall.
Leg Elevation Wedge
Placed under the calves and legs to elevate them 6–12". Uses: varicose veins, edema/swelling, post-surgical recovery (knee/hip replacement), restless leg syndrome symptom relief, lower back pain (reduces lumbar pressure when lying on your back).
Under-Knee Wedge
Smaller wedge placed under the knees when lying on your back — reduces pressure on the lumbar spine by flattening the lumbar curve. Good for back pain sufferers who sleep supine.
Side-Sleeping Wedge
Between-knee wedge that maintains hip alignment for side sleepers. Reduces hip and knee joint stress. Often recommended post hip surgery.
Wedge Pillow for Acid Reflux
Gravity is the key mechanism: elevating the head and torso keeps stomach acid below the lower esophageal sphincter. Studies show a 30–45° elevation reduces nighttime GERD symptoms significantly. Key specs:
- Height: 7–10" for mild reflux; 10–12" for severe GERD
- Width: At least as wide as your shoulders (24"+ for most adults)
- Angle: Gradual slope — not a steep ramp that creates a sharp bend at the waist
- Cover: Removable, machine washable (drool and reflux incidents happen)
Wedge Pillow for Sleep Apnea
For positional sleep apnea (apnea that occurs predominantly on the back), wedge pillows can reduce events by promoting side sleeping or elevated positioning. Note: wedge pillows are NOT a substitute for CPAP therapy in diagnosed sleep apnea — they're a supplement that may reduce event frequency in mild cases or improve CPAP comfort.

Foam Density for Wedge Pillows
Wedge pillows must be firm enough to maintain their shape under body weight — they can't sag or the therapeutic angle is lost:
- Minimum: 2.0 PCF polyfoam — budget option that works but may compress over time
- Recommended: 2.5 PCF polyfoam or memory foam — holds angle well for 3–5 years
- Premium: High-resilience foam or natural latex — best durability, 8–10 years

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.

FAQ
What height wedge pillow is best for acid reflux?
7–10 inches is the recommended range for most GERD sufferers. This achieves a 30–45 degree incline that uses gravity to keep stomach acid below the esophagus. Taller wedges (10–12") are better for severe acid reflux or hiatal hernia.
Can a wedge pillow help with sleep apnea?
For positional sleep apnea, yes — elevation can reduce apnea events. However, wedge pillows are not a replacement for CPAP therapy. Consult a sleep physician before substituting positional therapy for prescribed CPAP treatment.
How do you sleep comfortably on a wedge pillow?
Place the wedge under your upper torso so the incline starts at your hips — not your waist. Add a regular pillow on top of the wedge for head support. It takes 1–2 weeks to adjust. Side sleeping on a wedge is more comfortable for most people than back sleeping.
