These mattresses are built for a standard bed frame, box spring or platform bed rather than an adjustable base — solid, no-flex support for a classic setup. Shopping by feel or build instead? Browse by comfort (plush, medium, firm) or by type (memory foam, hybrid, pocket coil, traditional). Using an adjustable base? See our adjustable-bed-compatible mattresses. Every order includes a 365-night sleep trial and free delivery across Canada.

How to Choose the Right Bed Frame for Your Mattress
The right bed frame protects your mattress investment and directly affects sleep quality. A proper foundation prevents premature sagging, maintains manufacturer warranty coverage, and improves airflow beneath the mattress. National Mattress carries three main types of bed frames: traditional metal frames from Leggett & Platt that pair with a box spring, platform bases from Serta and Bedder Base that eliminate the need for a box spring entirely, and hardwood platform bedframes that combine a sleek design with built-in slat support.
Metal frames like the Lev-R-Lock® and Inst-A-Matic® are the most affordable option starting at $100, but require a separate box spring or foundation. Platform bases such as the Bedder Base® (tested to 3,000 lb capacity) and the Serta® Pro Platform™ provide a complete support system with no box spring needed — ideal for mattress-in-a-box products and foam mattresses. For a furniture-grade look, the NM Platform Bedframes feature hardwood construction with slats spaced less than 2” apart, headboard compatibility, and a 10-year warranty.
