Our Bunk Beds are constructed of solid Eco-Friendly hardwood and protected by our high build five step finishes. The beds use 26 point steel reinforcement with mortise & tenon joinery, and have matching guard rails designed to accent the style of the upper end and lower end panels. Many models feature a built in modesty panel which strengthens & accentuates the bunk when adding a set of drawers or a trundle bed. These beds accept up to a nine inch mattress on the upper platform & allows your child plenty of headroom on the lower platform.
