Medium Springwall® Foam Natural & Organic Mattresses Adjustable Bed Base Friendly Edge Support Mattresses Default Category

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
Springwall Foam mattresses provide all-foam comfort with excellent pressure relief and motion isolation. These Canadian-made mattresses use high-density foams (including eco-friendly BioFoam) to offer supportive, budget-friendly sleep solutions.
For a cleaner, more eco-conscious sleep, our natural and organic mattresses are built with materials you can feel good about — natural Talalay latex, organic cotton and wool covers, plant-based and soy-derived foams, and recycled fibres, with low-VOC, CertiPUR-US® certified components. They're a great fit if you want fewer synthetic chemicals, more sustainable materials, or a naturally breathable, hypoallergenic feel. You'll find genuinely certified-organic options — like GOTS organic cotton and organic latex from Natura and Evergreen — alongside natural-material and eco-friendly builds from Serta iComfort ECO, Sealy, Beautyrest and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What "natural materials" means: Talalay latex, organic cotton & wool, plant-based/soy foams and recycled fibres • Certified-organic options: GOTS organic cotton and organic latex (Natura, Evergreen) • Eco-friendly builds: Serta iComfort ECO (REPREVE recycled) plus low-VOC, CertiPUR-US® foams • Best for: shoppers who want fewer synthetic chemicals, sustainable materials, or a naturally breathable feel • Looking specifically for latex? See our latex mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
