To sleep comfortably you need a comfy mattress that supports the body well. Our heavy-duty bed support provides mattress support and eliminates the need for a box spring. Wooden slats provide strong and sturdy support for your memory foam or spring mattress as well as prevent sagging and increase the longevity of a mattress. All of our platform beds and loft beds come with 13-bed slats. Bed support slats make the bed usable for any twin, full, or queen mattress. These slats are 2 1/2" wide and are spaced 3 1/2" apart from one another. The slats are all connected to one another by two strips. All of our twin, full, and queen bunk beds include a full slat kit of 26 slats (13 for the top bunk and 13 for the bottom bunk)
