Quick Answer: The best soft mattress in Canada is one that relieves pressure at your specific pressure points without compromising spinal support. Research in the Journal of Chiropractic Medicine identifies the shoulder, hip, and iliotibial band as the most common pressure-point complaint sites for side sleepers. A soft mattress (3-5 on the 1-10 firmness scale) with a memory foam or gel foam comfort layer relieves these points. Our most-recommended soft mattresses at Mattress Miracle Brantford are the Gel Comfort Cooling Memory Foam and the Lauren Euro Top (medium with plush pillow top).

The Four Pressure Points That Matter
A soft mattress matters most for side sleepers, who have four distinct pressure points where body weight concentrates against the mattress surface. When the mattress is too firm, these points compress, cutting off circulation and causing nighttime movement. A well-chosen soft mattress relieves each one.
Pressure Points in Side Sleepers
Research in the Journal of Chiropractic Medicine and clinical observations from the Canadian Chiropractic Association identify the shoulder, hip, iliotibial band/outer thigh, and knees/ankles as the main pressure-point complaint sites for side sleepers. Pressure points that cut off circulation cause nighttime movement (turning and adjusting), which fragments sleep and reduces restorative deep sleep. Appropriate softness at each pressure point reduces compression and improves sleep quality measurably.
This article is educational. Individual pressure relief needs vary by body weight, body shape, and health conditions.
Pressure Point 1: Shoulder
For side sleepers, the shoulder takes about 25 percent of body weight when lying on one side. A too-firm mattress pushes back against the shoulder, compressing the rotator cuff and the deltoid muscles against the collarbone. This is the most common source of "pillow is wrong" complaints that are actually mattress problems.
What Works for Shoulder Relief
- Memory foam comfort layer (3+ inches). The shoulder sinks in, neutralizing the pressure.
- Zoned mattress with softer shoulder zone. Premium hybrids sometimes have explicit softer coils in the shoulder area.
- Pillow-top or Euro top. Adds 2-3 inches of plush material, allowing shoulder compression.
- Adjustable base with slight head elevation. Elevates upper body, reducing shoulder compression slightly.
Pressure Point 2: Hip
The hip is the second major pressure point for side sleepers. Unlike the shoulder, the hip benefits from sinking slightly into the mattress to keep the spine in neutral alignment. A too-firm mattress leaves the hip sitting high, bowing the spine.
What Works for Hip Relief
- Medium to medium-firm with deep comfort layer. The hip sinks to align with the shoulder.
- Memory foam over a firm base. Memory foam contours to the hip curve. Firm base supports spine alignment.
- Gel memory foam. Contours without heat buildup. Best-selling option for hip relief.
- Avoid pure firm mattresses for side sleepers with hip pain. The hip does not sink and the lumbar curve is stressed.
Pressure Point 3: Iliotibial Band and Outer Thigh
The IT band runs from the outer hip down the outer thigh. For side sleepers, particularly those with tighter IT bands or hip bursitis, this long muscle can press painfully against a firm surface. A soft comfort layer distributes the pressure across the longer section.
What Works for IT Band Relief
- Soft to medium foam comfort layer. Distributes pressure along the full length of the thigh.
- Memory foam specifically. Contours along the entire thigh shape.
- Knee pillow. Placed between the knees, keeps hip and IT band at neutral angle. Often combined with appropriate mattress for maximum relief.
Pressure Point 4: Knees and Ankles
For some side sleepers, especially those with arthritis, the knee or ankle rests against the mattress in a way that creates pressure. Less common than shoulder or hip but real.
Knee and Ankle Relief
- Knee-between-knees pillow. Reduces direct mattress pressure on knee joints.
- Medium-soft foam layer. Allows knee to gently compress into surface rather than bearing direct pressure.
- For ankle pain, adjustable base with slight foot elevation. Reduces blood pooling and takes pressure off ankle joints.
Softness Tiers and Sink Depth
Softness Tiers by Sink Depth
- Tier 1: 1-2 inches sink (Medium-Firm, 5-6). Minimal pressure relief. Supportive but firm feel. For heavier side sleepers who need support priority.
- Tier 2: 2-3 inches sink (Medium, 4-5). Moderate pressure relief. Sweet spot for most side sleepers of average weight.
- Tier 3: 3-4 inches sink (Soft, 3-4). Deep pressure relief. For side sleepers with joint issues, lighter sleepers, or those who want a "cradling" feel.
- Tier 4: 4+ inches sink (Plush, 2-3). Deep hugging sensation. For very light side sleepers or very specific comfort preferences. Less spinal support; not suitable for heavier sleepers.
When a Mattress Becomes Too Soft
Soft is not universally better. A too-soft mattress creates its own problems that can masquerade as unrelated issues.
Signs Your Mattress Is Too Soft
- Waking with lower back pain. Hip sinks too deep; lumbar bends. Usually means softness exceeds body weight tolerance.
- Difficulty getting out of bed. Too much sink makes it hard to push up to sitting.
- Feeling "stuck" during sleep. Excessive sink traps sleepers, making it hard to reposition.
- Heat retention. Deeper sink means more body contact with foam, trapping more heat.
- Couple imbalance. One partner rolls toward the other. Too soft for combined weight.
Our Soft Mattress Options
Testing Softness in Our Showroom
After 37 years in Brantford, we have learned that softness is the hardest variable to evaluate without lying on the mattress. Bring a partner, bring your own pillow, and lie down in your actual sleep position for 15-20 minutes. Your body will tell you whether the softness works. Our showroom has options from medium-firm to plush so you can compare side by side.

Frequently Asked Questions
What is the best soft mattress in Canada for side sleepers?
A medium to medium-soft mattress (3-5 on the 1-10 scale) with a memory foam or gel foam comfort layer of 2-3 inches. Our Gel Comfort and Lauren Euro Top both fit this range and are our most-requested for side sleepers.
Is a soft mattress bad for my back?
Not inherently. Many side sleepers with back pain benefit from soft. But a mattress too soft for your body weight will cause back pain from excessive hip sink. Match softness to body weight and sleep position.
Can I make a firm mattress softer instead of buying new?
Yes, within limits. A memory foam topper (2-3 inches) adds significant softness and pressure relief to a firm mattress. This is often our first recommendation for customers hesitant to replace.
Do soft mattresses wear out faster?
Not necessarily. Quality soft memory foam or hybrid mattresses last 8-12 years, same as firm. Cheap soft mattresses sag quickly, but cheap firm mattresses fail in other ways (coil degradation). Quality materials matter more than firmness.
Should couples with different firmness preferences buy soft?
Depends on the range of difference. For a small gap (one prefers 5, the other 6), a medium-firm hybrid works for both. For a large gap (one prefers 3, the other 7), consider a split king on adjustable base with different firmness each side.
