The Duro Z Bunk Bed Loft with Desk White combines economy with versatility to create a single-bed unit that s ideal when dealing with limited space. Instead of a lower bunk this piece incorporates a desk and work area in its sharp geometric design. Solid metal is given a glossy white finish that adds to its breathy design without sacrificing sturdiness. The frame supports a twin-sized mattress with safety rails and a removable ladder (capable of supporting up to 320 lbs.). In addition to children this piece is also worth considering as playful alternative for the college students and studio apartment owners. We take your family’s safety seriously. That’s why all of our bunk beds come with a bunkie board slat pack or metal grid support system. These provide complete mattress support and secure the mattress within the bunk bed frame. Please note: Bunk beds and loft beds are only to be used by children 6 years of age or older.
