Adjustable Comfort: Customize the lumbar support of your mattress from plush to firm for perfect contouring support. The engineered wood slats are lighter, stronger, and more durable than traditional wood. 2 extra slats included. Contouring Support: Unlike metal platforms, our unique wood slat design flexes with your mattress. Get extra contouring lumbar support from the 3 double center slats for pressure relief and better back support. Durable Steel Frame: Supports up to 1200 lbs.
