Best Side Sleeper Mattress and Pillow: Canada Buying Guide
The best side sleeper mattress for most people is medium to medium-soft. It should be soft enough at the surface that your shoulder and hip sink in, and firm enough underneath that your waist doesn't sag. Lighter people usually do best toward the softer end, heavier people toward medium-firm. Many shoppers skip the next part: a side sleeper also needs a firm pillow tall enough to fill the space between the ear and the outer shoulder, because even a well-matched mattress can't keep your neck straight on its own. Dosaze doesn't sell mattresses in Canada, but we do make side sleeper pillows and a mattress topper. This guide covers where those help and where you need something else.
What a mattress has to do for a side sleeper
Lying on your side, you touch the bed at two wide points (shoulder and hip) and you're narrower in between. On a mattress that's too firm, those two points carry most of your weight. People often notice a numb arm or an aching hip by morning, and they roll over more during the night. On a mattress that's too soft, the hips drop lower than the shoulders and the spine bends sideways.
You want a top layer that gives at the shoulder and hip, with a support layer that holds the waist up. Lie on your side in a showroom, or ask someone to look at you on your own bed. Your spine should run roughly level from neck to tailbone.
Picking a firmness
Firmness scales aren't standard between brands, so one company's "medium" can feel like another's "firm." Treat these as rough starting points:
- Under about 60 kg (130 lb), medium-soft, since you won't sink far into anything firmer
- About 60 to 100 kg (130 to 230 lb), medium
- Over about 100 kg (230 lb), medium-firm, often a hybrid with thick comfort layers so you don't press through to the support core
If you share the bed with a back or stomach sleeper, medium is the usual compromise.
Mattress types compared
| Type | How it feels on your side | Suits | Trade-off |
|---|---|---|---|
| Memory foam | Deep contouring at shoulder and hip, slow to spring back | Light to average-weight sleepers who stay in one position | Can feel warm; harder to change position |
| Hybrid (foam or latex over pocketed coils) | Contouring on top, springier underneath | Most side sleepers, including heavier and combination sleepers | Heavy, and usually costs more than all-foam |
| Latex | Buoyant; contours less deeply than memory foam | People who want pressure relief without the sinking feel | Very heavy; some find it bouncy |
| Innerspring | Firmer surface with little contouring | Rarely a first choice unless it has a thick pillow top | Pressure builds at the shoulder and hip |
Plenty of mattresses in Canada are sold online as bed-in-a-box, including Canadian brands such as Endy, Silk & Snow, Novosbed and Douglas. Others, like Sealy, Serta and Tempur-Pedic, are easy to try in person at retailers such as Sleep Country. Because firmness labels vary so much, check the length of the home trial and what a return costs before you buy.
When a topper makes more sense than a new mattress
Say your mattress still supports you (no dip where you sleep) but feels hard under the shoulder. A topper adds a softer comfort layer for far less than a new bed, and Dosaze makes the DreamAlign Side Sleeper Mattress Topper for that situation.
But a topper won't fix sagging. If there's a visible body impression or the middle has given way, the topper will settle into the same dip, and it's time to replace the mattress.
Why side sleepers need a firm pillow
The gap between your head and the mattress on your side is about the width of your shoulder, often 10 to 15 cm (4 to 6 inches) depending on your build. A pillow has to fill that and stay filled all night. Soft polyester fill or down often starts at the right height and then flattens under your head, which is why so many side sleepers end up folding the pillow in half or pushing an arm under it at 3 a.m.
Your mattress changes the number. A softer mattress lets the shoulder sink, so the gap shrinks and you need a little less loft. On a firm mattress you need more.
Fill materials for a firm side sleeper pillow
- Memory foam holds its height and shapes to the neck, though a moulded pillow has one fixed height.
- Shredded foam lets you add or remove fill and breathes better than a solid block, but it can clump and needs fluffing.
- Latex is springy and durable, and many people find it cooler than memory foam.
- Buckwheat is very firm and holds whatever shape you push it into. It's also heavy and rustles when you move.
- Down and down alternative feel soft and usually compress too much for dedicated side sleepers.
Where Dosaze pillows fit (and where they don't)
Our three orthopaedic pillows use premium memory foam that is CertiPUR-US certified, with a naturally cooling, antimicrobial fabric and a removable cover you can wash. All three ship locally within Canada.
If you spend most of the night on your side, start with the Dosaze™ Contoured Orthopedic Side Sleeper Pillow. It's contoured to cradle the curve of the neck and designed to keep the spine aligned while you sleep.
The Dosaze™ Contoured Orthopaedic Pillow takes the same contoured memory foam approach and is made for side, stomach and back sleepers, so it suits people who change position through the night.
The Cervical Orthopaedic Pillow is shaped around the cervical spine (the C1 to C7 vertebrae) and promotes a side and back sleep posture. It's the better match if you start on your back and roll to your side.
Where they fall short: a shaped memory foam pillow has a set height. If you're very broad through the shoulders or quite petite and standard pillows have never fit you, an adjustable shredded-fill pillow gives you more room to experiment. Memory foam also responds slowly, so people who flip constantly sometimes prefer latex. And no pillow makes up for a mattress that sags under your hips.
Signs your setup isn't working
- Neck stiffness that eases within an hour of getting up
- Pins and needles in the arm you sleep on
- An aching hip on your sleeping side
- Folding, stacking or hugging your pillow to get comfortable
- Waking up to turn over many times a night
Neck and arm complaints usually point at the pillow first. Hip and lower back aches more often point at the mattress.
Frequently asked questions
Should a side sleeper get a soft or firm mattress?
Most side sleepers do best on medium to medium-soft, which lets the shoulder and hip sink in while the waist stays supported. Heavier people often need medium-firm so they don't sink too far. A very firm mattress tends to put pressure on the shoulder and hip.
Is a firm pillow better for side sleepers?
Usually, yes. A side sleeper's pillow has to fill a gap of roughly 10 to 15 cm (4 to 6 inches) between the head and mattress, and soft fills tend to flatten under the weight of the head. Memory foam, latex and dense shredded foam hold their height better through the night.
Can a mattress topper make my mattress better for side sleeping?
If your mattress is still supportive but feels too hard at the shoulder, a topper can add a softer comfort layer for much less than a new mattress. It won't fix a mattress that sags or has a deep body impression. In that case the topper sinks into the same dip.
How high should a pillow be for a side sleeper?
A common starting point is 10 to 15 cm (4 to 6 inches), matched to how broad your shoulders are. On a softer mattress your shoulder sinks more, so you may need a little less height. On a firm mattress you may need more.
