Twin Size Medium Temperature-Regulating Mattresses Best Mattresses For Back Sleepers
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. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
A temperature-regulating mattress works to keep you at a comfortable, balanced temperature all night and all year — not just cooling you down, but adapting as your body and the seasons change so you don't wake up too hot or too cold. These mattresses use heat-responsive and breathable materials — phase-change covers, gel and graphite foams, Tencel and natural fibres, and airflow-promoting coils — to absorb and release warmth as needed. It's ideal if you run hot and cold, share a bed with a partner who sleeps at a different temperature, or just want consistent comfort through every season. You'll find temperature-regulating builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot specifically? See our cooling mattresses. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: holds a balanced, neutral temperature — adapts so you're not too hot or too cold • How it works: phase-change covers, gel & graphite foams, Tencel/natural fibres and breathable coil airflow • Best for: people who run hot and cold, couples with different sleep temperatures, and year-round comfort • Cooling vs regulating: cooling sleeps cold (for hot sleepers); regulating holds a steady, balanced temp • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

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 130+ 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 5–25 year warranty coverage.
