Twelve plywood slats span the 80 x 60 in bed surface to form a stable platform that supports up to 660 lbs without needing a box spring, so your mattress is directly supported. Three middle support legs with adjustable foot pads help keep the 82.5-in long frame level on uneven floors and reduce wobble as you move. The comfortable high headboard creates a supportive backdrop for bedtime reading or relaxing. A 9-in under-bed space provides open storage and allows a sweeper to pass through for easier cleaning. The embedded mattress design helps prevent sliding and sagging so the bed stays neatly made.
