Quick Answer: The best wedge pillow depends on your need. For acid reflux, a 7 to 8 inch tall wedge at 30 degrees keeps stomach acid down. For snoring, a similar height helps open the airway. For reading in bed, 10 to 12 inches provides a comfortable angle. Prices in Canada range from $40 to $100 CAD. Look for CertiPUR-US foam with a washable cover.

What Is a Wedge Pillow?
A wedge pillow is a triangular foam block that elevates your upper body, legs, or both at a gradual angle. Unlike stacking regular pillows (which creates a bend in the neck), a wedge pillow provides a smooth, even incline from the lower back to the head.
Most wedge pillows are made from polyurethane foam or memory foam. They come in different heights and angles depending on the intended use. Some have a memory foam top layer over a firmer base for comfort without sacrificing support.
Uses by Condition
Acid Reflux and GERD
This is the most common reason people buy wedge pillows. Gastroesophageal reflux disease (GERD) causes stomach acid to flow back into the oesophagus, especially when lying flat. Elevating the upper body uses gravity to keep acid in the stomach.
Research on Elevation and Reflux
A study published in the Journal of Gastroenterology and Hepatology found that sleeping with the head of the bed elevated by 15 to 20 centimetres (6 to 8 inches) significantly reduced oesophageal acid exposure and reflux symptoms. The American College of Gastroenterology recommends head-of-bed elevation as a first-line non-pharmacological treatment for nighttime GERD.
Snoring and Sleep Apnea
Elevating the head opens the airway by pulling the tongue and soft palate forward with gravity. This can reduce or eliminate snoring in mild cases. For obstructive sleep apnea, a wedge pillow is not a replacement for CPAP therapy but can be used alongside it. See our sleep apnea pillow guide for more information.
Post-Surgery Recovery
After shoulder, back, or abdominal surgery, many doctors recommend sleeping at an incline. A wedge pillow provides a stable, consistent angle that regular pillow stacking cannot match. It also prevents rolling during sleep.
Sinus Congestion
Elevation helps sinuses drain, reducing nighttime congestion. People with chronic sinusitis, allergies, or head colds often find a wedge pillow provides immediate relief.
Pregnancy and Heartburn
Many pregnant people develop heartburn in the second and third trimesters as the growing uterus presses upward. A 7 to 8 inch wedge pillow elevates the upper body enough to keep stomach acid down, which often makes a measurable difference for pregnancy-related reflux. The wedge can also be flipped under the knees in late pregnancy to reduce swelling and lower back strain. Always check with your prenatal care provider before changing sleep positions if you have a high-risk pregnancy.
Reading and Watching TV
A taller wedge (10 to 12 inches) provides a comfortable semi-reclined position for reading in bed. See our reading pillow guide for more detail on this use case.
Wedge Pillow Sizes and Angles
| Height | Angle | Best For | Comfort Level |
|---|---|---|---|
| 5 to 6 inches | ~20 degrees | Mild reflux, light elevation | Easy to adjust to |
| 7 to 8 inches | ~30 degrees | Acid reflux, snoring, GERD | Most popular, good balance |
| 10 to 12 inches | ~40 degrees | Reading, post-surgery, severe reflux | Steeper, may need adjustment |
| 14+ inches | ~50 degrees | Upright sitting, severe conditions | Steep, not ideal for sleeping |
The most versatile size is 7 to 8 inches. It provides enough elevation for acid reflux and snoring while being comfortable enough for all-night sleeping. Taller wedges work for reading and recovery but can feel too steep for overnight use.
Width Matters
Standard wedge pillows are about 24 inches wide. Body-width wedges (30 to 36 inches) are more comfortable because they support the entire torso, not just the head and neck. If you roll or shift during sleep, a wider wedge prevents you from sliding off the edge.
Best Wedge Pillows in Canada
From the showroom: Dorothy at Mattress Miracle has fitted Brantford customers with wedge systems for over a decade. "We see two patterns. Customers who buy a single 7-inch wedge online and call us a month later because it slides on the bed, or because the foam is too soft and they sink into it. The fix is usually a four-piece wedge system with a torso wedge and a knee bolster. The torso wedge stays put because the bolster locks it in place. That single change resolves about 80% of the complaints we hear."
The most reliable wedge pillow we stock is the Symbia Orthopedic Wedge Pillow ($125 CAD), a four-angle modular system from Orthex that combines a torso wedge, knee bolster, and pillow into a single setup. It is the same system featured in many physiotherapist-recommended Canadian recovery setups. Available in our Brantford showroom for in-person testing.

| Pillow | Height | Material | Price (CAD) | Notes |
|---|---|---|---|---|
| InteVision Foam Wedge | 7.5" | Foam + memory foam top | $60 - $80 | Best seller, two-layer design |
| Brentwood Home Zuma | 7" or 10" | CertiPUR-US foam | $70 - $90 | Therapeutic grade, washable cover |
| Relax Home Life Wedge | 7.5" | Memory foam | $55 - $75 | Good value, Egyptian cotton cover |
| Medslant Wedge Pillow | 7" | Foam with channel design | $80 - $100 | Full torso width, medical grade |
| Amazon Basics Wedge | 8" or 12" | Polyurethane foam | $35 - $55 | Budget option, basic foam |
How to Sleep on a Wedge Pillow
Back Sleeping
Place the wide end at the bottom of the wedge against your mattress. The thin end should be at the top. Lie with your lower back at the base and your head at the top of the incline. You can place your regular pillow on top of the wedge for additional head comfort. Place a second pillow under your knees to reduce lower back strain.
Side Sleeping
Side sleeping on a wedge is less intuitive. Some people place the wedge under their regular pillow to create a gradual elevation. Others use a wider wedge and sleep on their side across it. A body pillow in front can prevent rolling forward off the wedge.
Leg Elevation
Flip the wedge around and place it under your knees or calves for leg elevation. This helps with varicose veins, leg swelling, and lower back strain. The incline encourages blood flow back toward the heart.
Wedge Pillow Tips
Breaking in: New foam wedge pillows can feel firm. They soften slightly over the first 1 to 2 weeks of use.
Sliding prevention: If the wedge slides on your mattress, place a non-slip pad underneath.
Pillowcase: Use a large pillowcase or the included cover. A standard pillowcase will not fit most wedge pillows.
Combining with head pillow: Many people put a thin standard pillow on top of the wedge for extra head comfort. This is fine as long as the total elevation does not cause neck strain.
Adjustable Bed: The Permanent Solution
If you need to sleep elevated regularly (chronic GERD, ongoing snoring, post-surgery recovery), an adjustable bed base is the most comfortable long-term solution. Unlike a wedge pillow, an adjustable base raises the entire mattress surface, providing a smooth incline for your whole body rather than just the upper torso.
At Mattress Miracle, we carry adjustable bases that pair with most mattresses. The head can be raised to any angle from flat to fully upright, giving you precise control. Many customers who start with a wedge pillow eventually upgrade to an adjustable base and tell us it was one of their best sleep investments.

Wedge Pillow in Quebec (Oreiller Cunéiforme)
Quebec retailers list wedge pillows as "oreiller cunéiforme", "oreiller en coin", or "oreiller incliné". The materials, angles, and recommended heights are identical to the rest of Canada. Brand names like Symbia, Comfort Sleep, and InteVision are sold under their English names with French product descriptions.
Frequently Asked Questions
What size wedge pillow is best for acid reflux?
A 7 to 8 inch tall wedge at about 30 degrees is recommended by gastroenterologists for acid reflux. This provides enough elevation to keep stomach acid down while remaining comfortable for sleeping. A body-width wedge (30+ inches) is more comfortable than a narrow one.
Do wedge pillows help with snoring?
Yes. Elevating the head keeps the airway more open by pulling the tongue and soft palate forward with gravity. A 7 to 10 inch wedge is typically effective. For diagnosed sleep apnea, use a wedge alongside your CPAP therapy, not as a replacement.
Can you use a wedge pillow on its side?
Yes. Some people use wedge pillows on their side for lateral support or to prevent rolling. Specialty wedge sets include configurations for side sleeping. A standard wedge can also be placed behind the back for support when lying on your side.
How long does it take to adjust to a wedge pillow?
Most people adjust within 3 to 7 nights. The incline feels unusual at first, especially if you are used to sleeping flat. Placing a pillow under the knees helps with lower back comfort during the transition. Start with a lower wedge if 7 to 8 inches feels too steep.
