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. The 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 manufacturer warranty information available.
