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.

🍁

Canadian-Made Quality

100% of edge support mattresses at National Mattress are manufactured in Canadian factories with free delivery and warranty coverage up to 25 years.

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.

Not Sure Which Edge Support Mattress Is Right for You?

Our non-commissioned sleep experts can help you compare edge support technologies and find the right firmness for your sleep style — no sales pressure, just honest guidance.
