Yes the Duro Wesley Twin over Full Bunk Bed – Silver is perfect in a shared kids room but think of its other applications. It can blend effortlessly into a one-kid room or even dorm room too where a tween teen or soon-to-be grad can sprawl out with homework or games on the spacious bottom bunk before crawling to sleep on the smaller top bunk. This no-nonsense bunk bed a Hayneedle exclusive you won’t find anywhere else is crafted with super-durable tubular metal finished in a sleek silver shade. An included ladder attaches to the bed sitting between the lower and upper bunk well above the floor so there’s no chance of tripping over bottom rungs. The top bunk is outfitted with slatted guard rails for maximum safety too no matter the age or size of the sleeper. Mattress height should not exceed 8 inches; manufacturer recommends using a 6-inch thick mattress.
