Three-level height adjustable vertical channel headboard lets you match the full-size platform bed to different mattress heights and sitting positions, creating a supportive backrest when reading or watching TV. Soft gray velvet upholstery over high-density sponge adds a cushioned surface along the headboard and frame. Ten wooden slats, extra middle metal support legs, and sturdy inclined outer legs work together to distribute weight evenly up to 800 lbs for stable use. A 6.5-in under-bed space leaves room for most sweeping machines to clean underneath, while noise-free foam and non-slip foot pads help limit movement and protect floors. Hook and loop fasteners hold the slats in place for easier assembly and long-term support.
