Why Side Sleeping Causes Hip Pain
Hip pain from sleeping on your side is one of the most common complaints we hear in our Brantford showroom. It's almost always caused by the same underlying issue: the mattress is either too firm to allow proper hip sink, or too soft to maintain spinal alignment underneath.
Here's what happens biomechanically. When you lie on your side, your hip is the widest point of your body contacting the mattress. If the mattress is too firm, your hip pushes against a resistant surface and can't sink to the natural alignment point of your spine. The result is lateral pressure on the greater trochanter , the bony prominence on the outer hip , and associated joint and soft tissue discomfort.
If the mattress is too soft, the opposite problem occurs: your hip sinks too deeply, bringing it below the level of your lumbar spine and creating a lateral curve. This puts the hip joint and the IT band (iliotibial band) under chronic tension throughout the night.
The ideal mattress for side sleepers with hip pain finds the balance: soft enough at the surface to allow the hip to sink 1-2 inches without hitting resistance, and firm enough in the support layer to prevent the hip from sinking beyond spinal neutral.
On hip pressure and sleep surface hardness: Research published in Applied Ergonomics (Jacobson et al., 2010) found that interface pressure at the hip and shoulder increased significantly on surfaces that were either too firm or too soft for the individual's body weight. A 2015 study in Sleep Health (Radwan et al.) confirmed that zoned support systems , where the hip region has different compliance than the shoulder region , produced significantly better pressure distribution and reported less discomfort than uniform-firmness surfaces for side sleepers. These findings are the scientific basis behind zoned coil and zoned foam mattress designs.
Brad, Owner, 40+ years of experience: "The most common thing I see with side sleepers who come in with hip pain is that they're on a mattress that was too firm when they were younger and heavier, and now that they've lost weight or their body has changed, it's even more of an issue. Or they went too soft because they thought that would help, and now they're sinking unevenly. The zone matters , you want the hip to have room to settle but not fall through."

What to Look For in a Mattress for Hip Pain
When you're evaluating mattresses for hip pain as a side sleeper, focus on these specific factors:
1. Zoned Support System
A zoned mattress has different firmness levels in different areas , typically softer at the shoulder and hip zones, firmer at the lumbar (lower back) zone. This is different from a single-firmness mattress. Zoned support allows the hip to sink appropriately without requiring the entire mattress to be soft.
Look for: mattresses that specifically mention zoned coils, zoned foam, or zone-differentiated construction. Restonic Revive models have 3-zone pocket coil systems. Casper Wave uses a 3-zone foam design. These are the mattresses that actually solve the biomechanical problem.
2. Pressure-Relieving Comfort Layer
The top comfort layer must be soft enough to distribute pressure across the hip rather than concentrating it at the bony prominence. Natural Talalay latex and high-density memory foam are the most effective materials for this. Talalay latex has the advantage of being more breathable and responsive; memory foam conforms more slowly but distributes pressure very effectively.
3. Adequate Thickness
A comfort layer of at least 2-3 inches is generally needed to adequately cushion a side sleeper's hip. Very thin comfort layers on budget hybrids don't provide enough material to prevent the hip from feeling the coil system below.
4. Edge Support
Side sleepers often sleep close to the edge of the mattress, especially in couples. Good edge support extends the usable sleep surface and prevents a rolling-off feeling that can disrupt hip alignment when sleeping near the mattress perimeter.
Does a Pillow Between Your Knees Help?
Yes , and this is one of the most reliably effective adjustments for side sleepers with hip pain, regardless of mattress type.
When you lie on your side without a pillow between your knees, your top leg falls forward. This internal rotation of the hip puts the hip abductors and IT band under sustained tension throughout the night. A pillow between the knees prevents this internal rotation, keeping the hip in a more neutral position.
Any firm-enough pillow works , a standard pillow folded in thirds, a cylindrical bolster, or a purpose-made knee pillow. The goal is to keep your knees and hips at roughly the same height, with your top leg parallel to the mattress rather than falling forward.
Think of the pillow between knees as addressing the position, and the mattress as addressing the surface. You need both for reliable relief from sleeping-related hip pain.
Best Mattress Options for Side Sleepers with Hip Pain
At Mattress Miracle in Brantford, we carry two primary options well-suited to side sleepers with hip issues:
Restonic Revive Tiffany Rose and Jasmine , $1,995 Queen
This is our most recommended mattress for side sleepers with hip or shoulder pressure concerns. The construction addresses the specific problem directly:
- 1,188 individually wrapped pocket coils in a 3-zone system (queen) , firmer lumbar support, softer hip and shoulder zones
- Talalay copper latex comfort layer , responsive, open-cell, cushions the hip point without trapping heat
- Canadian-made with a 10-year warranty
The Talalay latex is particularly effective for hip pain. Unlike memory foam, which slowly conforms and can feel like it's gripping you, Talalay latex responds immediately to pressure , the hip sinks in and the material pushes back proportionally. This creates pressure relief without the sensation of being stuck in a spot.
Restonic Luxury Silk and Wool , $1,395 Queen
The Luxury Silk and Wool uses natural silk and wool comfort layers over 884 zoned pocket coils. The wool provides a plush, cushioning feel at the hip contact point while the zoned coil system provides differentiated support. For sleepers who prefer natural materials and want genuine pressure relief without synthetic foam or latex, this is a strong option at a lower price than the Tiffany Rose.
Sleep In (Canadian-Made Flippable) , Mid-Range
Sleep In mattresses are dual-sided , you flip them every few months to distribute wear evenly. This is directly relevant for hip pain: the comfort layer of a single-sided mattress compresses at your usual sleep position over time, creating a body impression that can worsen hip pressure. A flippable mattress distributes this wear across two surfaces, which means the comfort layer maintains its cushioning for longer. Sleep In is Canadian-made and available at Mattress Miracle in Brantford.
Dorothy, Sleep Specialist: "When customers come in with hip pain, I always ask two things: what position do you usually wake up in, and how old is your current mattress? If it's over seven years old and you've been sleeping on the same side, there's almost always an impression forming that's making the problem worse. A new mattress with zoned support makes a significant difference. I also show them the knee pillow , it's inexpensive and often reduces hip pain within the first week."

What is the best mattress for side sleepers with hip pain in Canada?
A zoned pocket coil hybrid with a pressure-relieving comfort layer is the best choice. In Canada, the Restonic Revive Tiffany Rose ($1,995 queen, 1,188 zoned coils, Talalay copper latex) is one of the strongest options for side sleepers with hip pain. The zoned coil system allows hip and shoulder sink while maintaining lumbar support, and the Talalay latex provides responsive pressure relief at the contact point. Available at Mattress Miracle in Brantford.
Should I sleep on a soft or firm mattress with hip pain?
Neither extreme , a medium to medium-soft mattress with zoned support is typically most effective. Too firm concentrates pressure at the hip bony prominence. Too soft lets the hip sink past neutral alignment and stresses the hip joint differently. A zoned mattress allows the hip zone to be softer than the lumbar zone, which is the most targeted solution. If you're currently on a firm mattress with hip pain, a mattress topper in the 2-3 inch range can be a temporary improvement while you decide on a permanent solution.
Does a pillow between the knees really help hip pain from sleeping?
Yes. A pillow between the knees prevents the top leg from falling forward, which reduces internal hip rotation and the associated tension on the hip abductors and IT band. It works independently of mattress firmness , it addresses position rather than surface. For many side sleepers, a knee pillow reduces pain within a few nights. Combined with a zoned mattress, it's the most reliable approach.
Can a mattress cause hip pain?
Yes. A mattress that is too firm concentrates pressure on the hip's bony prominences and can cause pain at the greater trochanter (outer hip). A mattress that is too soft allows the hip to sink past neutral spinal alignment and strains the hip joint and IT band. A mattress with a body impression (depression from long-term use) creates an uneven surface that exacerbates both problems. If your hip pain improves when you sleep elsewhere, your mattress is likely a contributing factor.
Is Talalay latex good for hip pain?
Yes , Talalay latex is one of the most effective comfort materials for hip pain in side sleepers. Its open-cell structure responds immediately to pressure, conforming to the hip contour and distributing load across a wider area. Unlike memory foam, it doesn't create a slow-sinking, trapped sensation. The Restonic Revive Tiffany Rose uses Talalay copper latex as the primary comfort layer specifically for this reason. The copper infusion adds antimicrobial properties and a secondary cooling effect.
