Zenbase 12"H Metal Platform Bed Frame with Adjustable Legs, No Box Spring Needed, King

This platform base gives your mattress a firm, even feel from edge to edge. Its metal frame and smooth panels work together to keep the surface steady, whether you’re sitting or lying down. The legs adjust in 4-inch and 8-inch sections, so you can raise the base for storage or keep it low and simple. You can also remove the legs entirely when you want the frame to sit flat on the floor or inside an existing bed setup. The open underside helps air move freely, and the structure supports up to 770 lb, giving you a reliable foundation without the need for a box spring.
