Brad, Owner, 40+ years of experience: "We have been helping Brantford families sleep better since 1997. Every customer gets personal attention, honest advice, and the kind of follow-up service you just do not get from big box stores."
Wedge pillows are one of those products where the concept is simple but the details actually matter. The wrong angle does less than you need, or more than is comfortable. The wrong foam density collapses over time and stops providing support. And a wedge that's sized for a twin mattress shifts around all night on a queen.
Orthex has been making orthopedic sleep products since 2008 with a team of health professionals, occupational therapist, osteopath, physiotherapist, chiropractor, and doctor. Their Symbia wedge line reflects that background: it's designed around specific health conditions, not just the general idea of "elevation."
This guide explains which Symbia angle is right for which condition, what the foam construction actually means for long-term use, and how Orthex compares to the generic wedge pillows flooding the Canadian market.
What Is the Orthex Symbia?
The Symbia is Orthex's posture cushion and wedge pillow line, available in multiple angles for different therapeutic purposes. Unlike generic wedge pillows that come in one size, the Symbia line is segmented: each angle is designed for a specific elevation range and health application.
All Symbia wedges share the same core construction:
- Gel-infused memory foam, absorbs and dissipates body heat rather than reflecting it
- High-density base foam, maintains shape under sustained pressure; won't compress over weeks of use the way budget foam does
- Breathable, washable cover, the cover comes off and goes in the washing machine
- Non-slip base, stays in position on the mattress rather than migrating overnight
- 5-year warranty, Orthex warrants the foam against breakdown for five years
- Made in Canada, manufactured in Boisbriand, Quebec
Why Angle Matters More Than You'd Think
The American Journal of Gastroenterology and multiple clinical sleep studies consistently find that head-of-bed elevation of 20–30 cm (approximately 8–12 inches) significantly reduces nighttime acid exposure in GERD patients. That translates to a 23° or 30° wedge, not the 7–10° elevation that many "wedge pillows" actually provide.
Similarly, sleep apnea research shows that lateral position plus 15–30° head elevation reduces apnea-hypopnea index scores more than either intervention alone. Orthex angles the Symbia 30° specifically for this application, it's not marketing copy, it's the range that clinical guidelines suggest.
The Symbia Line: Every Model Explained
Symbia 14°, Shoulder Wedge and Light Elevation
Angle: 14 degrees
Price: ~$125 CAD
Best for: Shoulder support, relaxation, mild postural elevation, recovery from shoulder surgery
The 14° is the most gentle elevation in the Symbia line. It's less about acid reflux or airway management, and more about reducing shoulder compression for side sleepers and providing a comfortable reading-in-bed position.
Side sleepers who wake with shoulder pain often have too much pressure on the shoulder they're sleeping on, combined with insufficient support for the arm. The Symbia 14° elevates the torso gently and shifts weight distribution, reducing that lateral compression without the steeper angle that some people find uncomfortable for all-night sleep.
It's also the first choice for people recovering from shoulder or upper-body surgery where the goal is keeping the shoulder slightly elevated without the head being raised too aggressively.
Who should not choose the 14°: Anyone using the wedge primarily for acid reflux, GERD, or sleep apnea. The 14° elevation won't reach the clinical threshold for those conditions, you need the 23° or 30°.
Symbia 16°, Low Back Wedge and Lumbar Support
Angle: 16 degrees
Price: ~$140 CAD
Best for: Lumbar support, mild back wedge positioning, lower body elevation
The 16° occupies a middle position, slightly steeper than the 14° for more lumbar support, but still in the range that most people find comfortable for a full night's sleep. Depending on orientation, this wedge can serve as a back support cushion (placed under the lower back while in a reclining position) or a mild elevation wedge under the hips and thighs.
Many people who have chronic lower back pain sleep better with slight elevation under the knees (about 8–12°) to reduce lumbar disc pressure. The 16° placed under the knees achieves this without being steep enough to cause discomfort.
Symbia 23°, The Acid Reflux and Snoring Angle
Angle: 23 degrees
Dimensions: 24" × 28" × 12"
Price: $163–$170 CAD
Best for: Acid reflux, GERD, snoring, mild sleep apnea, pregnancy discomfort
The 23° is the most popular Symbia model, and for good reason. It sits precisely in the clinically recommended elevation range for GERD and acid reflux management (20–30 cm head elevation, which this angle achieves when used with a standard mattress and average-height pillow).
For snoring, the 23° elevation opens the airway by reducing the gravitational component of soft tissue collapse. This won't cure structural sleep apnea, but for positional snoring driven by gravity, a 23° wedge consistently reduces frequency and intensity.
Pregnant people in the second and third trimesters often find that a 23° back wedge while in semi-reclined sleep position reduces heartburn and makes breathing more comfortable �� the elevated angle reduces both acid exposure and diaphragmatic compression from the growing uterus.
Using the 23° vs. Pillow Stacking
The standard advice for GERD, "sleep with your head elevated", often translates to stacking two or three pillows. This creates cervical spine problems because the elevation is happening at the neck rather than the whole torso. You end up with the angle you need at the head but your torso is still flat, which reduces the anti-reflux benefit.
A wedge like the Symbia 23° elevates the whole torso uniformly, head, neck, and upper body are all tilted together. This is what the clinical research is actually testing when it recommends "head of bed elevation." It's fundamentally different from pillow stacking, and far more effective for reflux management.
Symbia 30°, Sleep Apnea and Significant Elevation
Angle: 30 degrees
Dimensions: 24" × 26" × 15"
Price: ~$180+ CAD
Best for: Moderate-to-significant sleep apnea support, severe GERD, respiratory conditions, post-surgical elevation
The 30° is the steepest back wedge in the Symbia line and the one most aligned with clinical applications. At 30°, the head elevation exceeds what most people find comfortable for all-night sleep on its own, which is why this wedge is typically used in combination with a standard pillow or as the primary sleeping surface for people with specific medical requirements.
For obstructive sleep apnea, the 30° elevation reduces the apnea-hypopnea index by making soft tissue collapse less likely, gravity is working against the obstruction rather than contributing to it. This is a complement to CPAP therapy, not a replacement, but many CPAP users find that adding the 30° wedge reduces the required pressure and improves comfort with the mask.
Post-surgical applications where elevation of the upper body is required, thoracic surgery, upper abdominal procedures, certain cardiac protocols, are where the 30° is most commonly recommended by healthcare teams for home recovery.
Symbia Leg, Knee, and Body Support
The Symbia line extends beyond back wedges:
- Symbia Knee Pillow (3"): ~$78 CAD, Keeps knees separated for side sleepers; reduces lateral rotation of the hip, which helps with hip and lower back pain. The 3" height corresponds to the typical gap between knees for most adults.
- Symbia Leg Bolster (10"): ~$118 CAD, Full under-leg bolster that elevates both legs uniformly. Used for venous insufficiency, edema reduction, post-leg-surgery recovery, and varicose vein discomfort.
- Symbia Leg Wedge (8°): Angled version for leg elevation with a specific tilt rather than uniform elevation.
- Symbia 50" Body Pillow: Full-length body pillow with shredded gel memory foam fill. For side sleepers who need full-body alignment support, keeps the shoulder, hip, and knee in alignment simultaneously.
Choosing the Right Symbia: A Quick Decision Guide
| Your Reason | Recommended Angle | Model | Price |
|---|---|---|---|
| Shoulder pain, light upper body elevation, reading in bed | 14° | Symbia 14° | ~$125 |
| Lumbar support, knee elevation, mild hip relief | 16° | Symbia 16° | ~$140 |
| Acid reflux, GERD, snoring, pregnancy comfort | 23° | Symbia 23° | $163–$170 |
| Sleep apnea support, severe GERD, post-surgery elevation | 30° | Symbia 30° | ~$180+ |
| Hip pain, side-sleeper knee separation | Knee pillow | Symbia 3" Knee | ~$78 |
| Leg swelling, varicose veins, venous insufficiency | Leg bolster | Symbia 10" Bolster | ~$118 |
Orthex Symbia vs. Generic Wedge Pillows in Canada
The wedge pillow market in Canada has been flooded with inexpensive foam wedges, mostly from Amazon, mostly made overseas, most in the $25–$60 range. It's worth understanding what you're actually comparing.
| Feature | Orthex Symbia | Generic Amazon Wedge | InteVision / Brentwood |
|---|---|---|---|
| Price range | $78–$180 CAD | $25–$55 CAD | $60–$120 CAD |
| Foam type | Gel memory foam + HD base | Standard polyurethane | Memory foam, varies |
| Foam compression (over time) | Minimal (high density) | Significant (often collapses) | Moderate |
| Angle accuracy | Clinically calibrated | Often overstated | Generally accurate |
| Washable cover | Yes | Sometimes | Yes |
| Non-slip base | Yes | Rarely | Some models |
| Warranty | 5 years | None or 30 days | 1–2 years |
| Made in Canada | Yes | No | No (US) |
The primary failure mode of cheap wedge pillows is foam compression. A $35 foam wedge typically compresses to half its original angle within 3–6 months of nightly use. If you're relying on the wedge for a medical reason, GERD management, sleep apnea support, that compression defeats the purpose. You're sleeping on a pillow that was a wedge, not a wedge.
Orthex's high-density foam construction is why they can offer a 5-year warranty. The foam is rated to hold its shape over extended use. That's the actual value proposition at $163 vs. $40, not the brand name, the material density.
Combining Symbia Products
Many people find the most therapeutic benefit from combining two Symbia products rather than relying on one. A few common pairings:
Effective Symbia Combinations
- 23° back wedge + 3" knee pillow: The standard pairing for GERD with lower back pain. The back wedge handles acid control; the knee pillow reduces lumbar tension that comes with sustained elevated sleeping.
- 30° back wedge + leg bolster: Used for sleep apnea with circulation issues. Both ends elevated simultaneously, which also approximates a mild zero-gravity position.
- 14° back wedge + 3" knee pillow: The recovery pairing for post-surgical patients who need gentle elevation without medical-grade angles.
- 23° back wedge + body pillow: Side sleepers who need acid reflux management. The body pillow keeps them from rolling off the wedge and maintains lateral positioning (which separately reduces reflux compared to supine sleeping).
If you're using a Symbia wedge alongside an Orthex Sophia adjustable bed, you probably don't need the back wedge at all, since the Sophia handles elevation electronically. The knee pillow or leg bolster makes sense as an add-on to a Sophia setup, especially in the positions where the foot section doesn't elevate the legs to the precise height you need.

Call 519-770-0001Can I use the Symbia wedge every night, or just occasionally?
The Symbia is designed for nightly use. The high-density foam construction is specifically rated for sustained daily compression, unlike thinner foam products that lose their shape after weeks of regular use. For conditions like GERD or sleep apnea, nightly use is the whole point: you need consistent therapeutic positioning, not occasional positioning.
Will the wedge slide around on my mattress at night?
The Symbia has a non-slip base. On most mattresses (including memory foam and innerspring), it stays in place through the night. Some very slick mattress covers can be an issue, if this is your situation, a fitted sheet over both the mattress and the wedge holds everything stable.
I've been told to elevate my head 6-8 inches for GERD. Which angle does that?
The clinical recommendation of 6–8 inches of elevation at the head of a standard bed translates to a wedge angle of roughly 20–30°, depending on your height and mattress thickness. The Symbia 23° achieves this range for most adults. If you're over 6'2" or using a thicker mattress, the Symbia 30° may be more accurate. When in doubt, the 23° is the more common choice for GERD management.
Does the Symbia work with adjustable beds?
The leg and knee support products (knee pillow, leg bolster) work well alongside adjustable beds. The back wedges are generally redundant if you have a Sophia adjustable bed, the Sophia provides electronically controlled elevation that does the same job with more precision and flexibility. The combination most common with a Sophia is the knee pillow or leg bolster to complement specific sleeping positions.
How do I clean the Symbia cover?
The zip-off cover is machine washable. Cold water, gentle cycle, air dry or low heat. Do not machine wash or wet the foam itself, the foam is not waterproof and takes a very long time to dry completely, which can cause mold. The cover alone is what needs regular washing.
Is the Symbia covered by my extended health benefits?
Some extended health plans cover therapeutic pillows and posture supports with a healthcare provider's written recommendation. Orthex products are used in clinical settings, and the Symbia in particular is recommended by physiotherapists and occupational therapists for specific conditions. Check your plan, coverage varies widely, but it's worth asking your insurer and having your prescribing provider use the product name and Orthex's specifications when submitting the claim.
What's the difference between the Symbia and the Somnia?
The Symbia is Orthex's wedge and posture cushion line, designed for elevation and positional support. The Somnia is their ergonomic pillow line for head and neck support in standard sleep positions. If you need torso or limb elevation, you want Symbia. If you need a better pillow for cervical spine support during side sleeping, you want Somnia. Many people use both.
