Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry.

These mattresses feature a grey or neutral-tone cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by size (twin to king), comfort (plush, medium, firm), or type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.

How to Choose the Right Mattress for Back Sleeping

Back sleepers need a mattress that keeps the spine in a neutral, straight line from shoulders to hips without letting the lower back sag or arch. A firm to medium-firm feel (5–8 out of 10 on the firmness scale) works best for most back sleepers because it supports the lumbar curve while still cushioning the shoulders. Among the back-sleeper models at National Mattress, over 64% of mattresses with zoned lumbar support use targeted coil or foam zones that reinforce the lower back without adding stiffness elsewhere.

Construction type matters as much as firmness. Pocket-coil and hybrid mattresses deliver responsive support that keeps heavier midsections from sinking, while memory foam and latex models contour gently around the spine. Over 90% of back-sleeper mattresses here are compatible with adjustable bases, a popular choice for back sleepers who elevate the head or knees to reduce pressure on the lumbar spine.

🦴

Firm to Medium-Firm Support

Over 82% of our back-sleeper collection is rated firm or medium-firm, the range most recommended for maintaining neutral spinal alignment.

🎯

Zoned Lumbar Support

398 of 621 SKUs feature zoned lumbar support that delivers firmer reinforcement under the lower back and softer cushioning at shoulders.

❄️

Cooling Technology

Back sleepers have more surface contact with the mattress. Over 80% of this collection includes cooling features like gel-infused foam, graphite layers, or breathable coil systems.

🍁

Canadian-Made Quality

91% of back-sleeper mattresses are manufactured in Canadian factories with CertiPUR-US® certified foams, free delivery, and manufacturer warranty information available.

Frequently Asked Questions About Mattresses for Back Sleepers

What firmness level is best for back sleepers?
Most back sleepers sleep best on a firm to medium-firm mattress rated 5–8 out of 10. This range supports the natural curve of the lumbar spine without creating pressure points at the shoulders. Lighter back sleepers (under 130 lb) may prefer medium, while heavier sleepers often benefit from extra-firm support.
Which mattress type is best for back sleepers, innerspring, hybrid, or foam?
All three types work well depending on personal preference. Pocket-coil and hybrid mattresses offer responsive support and strong edge stability. Memory foam contours closely to the spine, and latex provides bounce with natural pressure relief. Compare the models in each construction type to find the feel and support you prefer.
What is zoned lumbar support and why does it matter for back sleepers?
Zoned lumbar support uses firmer materials or thicker coils in the centre third of the mattress to prevent the heavier midsection from sinking. This keeps the spine level from shoulders to hips, the key factor for comfortable back sleeping. Over 64% of our back-sleeper collection includes this feature.
Can I use a back-sleeper mattress on an adjustable base?
Yes, over 90% of back-sleeper mattresses at National Mattress are compatible with adjustable bases. Elevating the head 10–15° or raising the knees can reduce lumbar pressure, making adjustable beds especially popular with back sleepers. Check each product page for the “adjustable base compatible” label.
What brands does National Mattress carry for back sleepers?
The back-sleeper collection includes: Serta, Beautyrest, Sealy, Springwall, Tempur-Pedic, Stearns & Foster, Chirofoam, Evergreen, iComfort by Serta, and NM by National Mattress. Check current Queen-size pricing on each product page.
Do back-sleeper mattresses ship free across Canada?
Read our delivery information for current availability and terms. Before ordering, review the sleep trial terms, price match policy, and manufacturer warranty information for the model you are considering.
