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 🍁.

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.
