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.
