Height adjustable headboard on this velvet upholstered full platform bed lets you match the chevron pattern to 10-12-in thick mattresses so the backrest supports you comfortably while sitting up. The 77.5 x 56 x 37.5 in frame uses 10 evenly distributed wooden slats, middle metal support legs and sturdy inclined legs to support up to 800 lbs without a box spring. High-density sponge under the soft velvet surface adds cushioning when you lean back. Noise-reducing foam between frame and slats helps limit creaks as you move. Raised side rails, an embedded mattress design and 6.5-in under-bed clearance help keep the mattress in place while leaving room for most sweepers to pass underneath.
