Need extra sleeping space without taking up more room? This HAUSHECK bunk bed is a triple threat – it's a twin-over-twin bunk bed plus a pull-out trundle bed underneath, so it can sleep three people comfortably. Perfect for kids' rooms, guest rooms, or vacation homes. The frame is all metal, so it's sturdy and stable, with a weight limit of 250 lbs for the top bunk, 350 lbs for the bottom, and 350 lbs for the trundle. It comes with a 4-step ladder and a full-length guardrail on the top bunk for safety. The slats are included (21 per bed), so you don't need a box spring – just add twin mattresses (up to 6\ thick for top, 8-10\ for bottom). Assembly is required, but everything you need is in the box. Overall size is about 78\ long, 41.75\ wide, and 62.25\ high. The trundle slides out smoothly when you need it and tucks away when you don't. The design is clean and black, so it fits with any decor. And because it's metal, it's quiet and doesn't squeak or shake. Great for siblings, sleepovers, or making the most of a small room.
