Side Sleeper, Back Sleeper or Stomach Sleeper: Here Is Your Ideal Mattress
For Side Sleepers
Side sleeping is the most common position in Australia and is generally considered one of the healthier ways to sleep. However, it places significant pressure on the hips and shoulders, which are the widest parts of the body and need to sink into the mattress enough to allow the spine to remain straight.
The ideal mattress for side sleepers:
• Medium to medium firm feel that allows the hips and shoulders to gently contour into the surface
• Memory foam or pocket spring systems that respond independently to pressure points
• Enough give in the top comfort layers to prevent shoulder pain without compromising lumbar support
• Zoned support systems that offer softer zones under the shoulders and firmer support under the hips
A mattress that is too firm for a side sleeper will push back against the hips and shoulders, creating pressure points and forcing the spine into an unnatural curve. A mattress that is too soft will cause the hips to sink too deeply, bowing the spine in the opposite direction.
For Back Sleepers
Sleeping on your back is widely regarded by physiotherapists and chiropractors as the most beneficial position for spinal health, provided the right mattress is in place. In this position, the body weight is distributed more evenly across the mattress, but the natural curve of the lower back needs to be properly supported.
The ideal mattress for back sleepers:
• Medium firm to firm feel that prevents the hips from sinking too deeply
• Consistent support across the full length of the body
• A surface that supports the lumbar curve without creating a gap between the mattress and the lower back
• Orthopaedic or spinal support designs that maintain neutral spine alignment
A mattress that is too soft will allow the lower back to sag, placing strain on the lumbar spine. A mattress that is too hard can create uncomfortable pressure at the tailbone and shoulder blades.
For Stomach Sleepers
Stomach sleeping is the least recommended position from a spinal health perspective, as it places the neck in a rotated position for extended periods and can cause the lower back to arch uncomfortably. However, many people naturally gravitate to this position and simply need a mattress that minimises the risks.
The ideal mattress for stomach sleepers:
• Firm to extra firm surface that prevents the hips from sinking and arching the lower back
• Minimal contouring so the body stays relatively flat and supported
• Thin or low profile pillow to reduce neck strain in combination with the mattress
• A stable, non bouncy feel that keeps the body level throughout the night
Stomach sleepers should avoid soft or plush mattresses entirely, as sinking hips will place the lumbar spine under significant strain over a full night of sleep.
For Combination Sleepers
Many Australians do not stay in one position all night. If you regularly switch between two or more positions, look for a mattress that offers a medium feel with responsive materials such as pocket springs or latex that adjust quickly as you move. Avoid very firm or very soft extremes, and prioritise a mattress with good edge support so you can use the full surface comfortably.
The Bottom Line
There is no single best mattress. There is only the best mattress for you based on how your body moves and rests during sleep. Taking the time to identify your sleep position and match it to the right orthopaedic mattress is one of the most effective things you can do for your long term spinal health.

FAQs
What mattress firmness is best for side sleepers?
Side sleepers benefit from medium-firm mattresses that provide moderate cushioning for shoulder and hip joints while maintaining spinal alignment. Mattresses that are too firm create pressure on these joints, while those too soft allow spinal misalignment. A responsive memory foam or pocket spring mattress with contouring support is ideal.
How can I make my mattress more comfortable for a side sleeper?
Add a high-quality mattress topper designed for side sleepers—memory foam or latex toppers add cushioning to pressure points. Ensure proper pillow support for your neck alignment and consider body pillows to reduce strain on hips and shoulders. Rotating your mattress regularly maintains even comfort across the surface.
Is foam or spring better for side sleepers?
Memory foam typically outperforms springs for side sleepers as it contours to shoulders and hips, reducing pressure and pain. Hybrid options combining foam comfort with spring support offer balanced benefits, while pure pocket springs may feel too firm on sensitive pressure points for side sleepers unless paired with thick comfort layers.
What mattress firmness is best for back pain?
Back pain sufferers require medium-firm mattresses that maintain the spine's natural curves without excessive sinking. This firmness level provides crucial lumbar support while accommodating your body's contours, reducing strain on muscles and discs. Avoid extremes—soft mattresses cause sagging while overly firm ones create uncomfortable pressure.
Is a firm mattress better than a medium mattress?
Medium mattresses often surpass firm options for general sleepers as they balance support with comfort and pressure relief. While firm mattresses benefit heavier individuals needing maximum support, most people experience fewer pressure points and better sleep quality with medium firmness. Personal testing is essential since preference varies significantly by body weight and sleeping position.
What is the difference between a firm, medium, and soft mattress?
Firm mattresses have minimal cushioning for maximum support, ideal for heavier sleepers and those needing strong spinal support. Medium mattresses offer balanced support and comfort suitable for most sleepers and sleeping positions. Soft mattresses prioritize comfort and pressure relief over support, best for lighter sleepers without back concerns. Choose based on your body weight and support needs.
Which mattress firmness is best for side sleepers?
Side sleepers need medium firmness that cushions shoulders and hips while maintaining spinal alignment. Medium-soft to medium firmness prevents excessive pressure on joints while providing adequate support—too firm creates uncomfortable pressure, too soft allows dangerous misalignment that aggravates sleep discomfort and pain.
Is a medium mattress good for couples?
Medium firmness is excellent for couples with varying preferences as it accommodates most body types and sleeping positions. Hybrid and pocket spring mattresses with motion isolation ensure one partner's movement doesn't disturb the other. A medium firmness provides compromise support without requiring someone to sacrifice comfort or spinal alignment.
What mattress firmness is best for stomach sleepers?
Stomach sleepers require firm to medium-firm mattresses that prevent excessive lower back sagging and maintain neutral spinal alignment. Soft mattresses create dangerous back arching and pain, while firm options keep the spine properly supported. Ensure adequate core support without excessive cushioning that sinks and misaligns the spine.
