Full Size Medium Plush Memory Foam Low Motion Transfer Mattresses Mattresses with Edge Support

Double/Full mattresses measure 54" × 75" — fifteen inches wider than a twin, giving a single sleeper plenty of room to spread out. They suit teens, single adults, and smaller bedrooms or guest rooms, and work for couples who prefer a cozier fit. Compare every double/full option below by brand, feel, and price.
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
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium
Memory foam mattresses contour to your body, relieving pressure at the hips and shoulders while absorbing motion so you won't feel your partner move. They give a cradling, "hug" feel that suits side sleepers and couples. Browse every memory foam option below by brand, feel, and profile.
If your partner tosses, turns or gets up during the night, a low-motion-transfer mattress keeps their movement from becoming your problem. These mattresses use individually wrapped pocket coils and motion-absorbing memory foam to isolate movement to one side of the bed — so when one of you shifts, the other barely feels it. It's one of the most important features for couples, and for anyone who shares a bed with a restless sleeper, a pet, or a partner on a different schedule. You'll find low-motion-transfer builds across every brand — Sealy, Serta, Beautyrest, Simmons, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in pocket-coil, hybrid and memory foam, every firmness from plush to firm. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: movement stays on one side — your partner's tossing won't wake you • How it works: individually wrapped pocket coils and motion-absorbing memory foam (vs connected innersprings that transfer motion) • Best for: couples, light sleepers, and anyone sharing a bed with a restless partner or pet • Builds: pocket-coil, hybrid and memory foam • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

What Is Edge Support and Why Does It Matter?

Edge support refers to the reinforced perimeter structure of a mattress that prevents sagging or roll-off when you sit or sleep near the sides. Mattresses with strong edge support use technologies like foam encasement, reinforced coil borders, or dedicated edge systems — such as Beautyrest’s BeautyEdge®, Sealy’s SolidEdge™ PRO, and Springwall’s SpringWALL Edge System — to create a stable, usable sleeping surface from edge to edge. This effectively increases the functional sleep area by up to 15–20%, which is especially valuable for couples sharing a Queen or King mattress.

When choosing an edge support mattress at National Mattress, consider your mattress type: pocket coil and hybrid models typically deliver the strongest perimeter stability, while memory foam mattresses with high-density foam encasement offer a solid alternative without coils. Firmness also plays a role — firm and extra firm mattresses naturally resist edge compression more than plush models. All 175+ edge support mattresses in this collection are CertiPUR-US® certified and manufactured in Canadian factories 🍁.

🛡️

Reinforced Perimeter

Foam encasement, BeautyEdge®, SolidEdge™, and SpringWALL Edge systems prevent roll-off and sagging along every side of the mattress.

🛏️

More Usable Sleep Surface

Strong edge support extends the functional sleeping area to the full mattress width — especially important for couples and shared beds.

Easier Entry & Exit

A firm, stable perimeter makes getting in and out of bed easier — a key benefit for older adults and those with mobility concerns.

Frequently Asked Questions About Edge Support Mattresses

Which mattress types have the strongest edge support?
Pocket coil and hybrid mattresses generally deliver the strongest edge support because their coil systems can be reinforced along the perimeter. Models using Beautyrest’s BeautyEdge® or Sealy’s SolidEdge™ PRO coil borders are among the firmest at the edges. Memory foam mattresses with high-density foam encasement also provide solid perimeter stability.
Why is edge support important for couples?
Reinforced edges prevent the “roll-to-the-centre” effect that happens when the perimeter compresses under body weight. This means each partner can sleep comfortably right to the edge, effectively maximising the usable surface area of a Queen or King mattress. It also makes sitting on the side of the bed more stable.
Can I use an edge support mattress on an adjustable base?
Yes — 100% of our mattresses with edge support at National Mattress are compatible with adjustable bases. Foam encasement and flexible pocket coil edges bend with the base without compromising perimeter stability. Check the “Compatible with Adjustable Beds” specification on each product page to confirm.
What edge support technologies do your brands use?
Each brand uses proprietary systems: Beautyrest features BeautyEdge® foam or coil encasement, Sealy uses SolidEdge™ PRO and EssentialEdge™ coil borders, Springwall uses its SpringWALL Edge System, and Stearns & Foster offers ventilated PrecisionEdge™ with AirVents™. NM-brand mattresses use HD+™ foam edge guards. Browse by brand on our edge support guide for detailed comparisons.
How much do edge support mattresses cost at National Mattress?
Edge support mattresses range from $136 for an NM-brand Twin to $5,690 for a King-size iComfort or Tempur-Pedic model. Queen-size prices start at $136 and go up to $5,690. All orders include free express delivery across Canada, a 365-night sleep trial, and our price match guarantee.
Does edge support make a mattress firmer overall?
Not necessarily. Edge support reinforces only the perimeter — the centre sleep surface retains its intended comfort level. You can find edge support mattresses across all firmness levels at National Mattress, from extra firm to plush. The edge system prevents side-sag without changing the feel where you actually sleep.
