The best bunk bed for adults, our Modern Queen High Bunk Bed with Ladder has over 3 feet of space between each bed when using a 5-inch mattress so adults, teens, and growing kids can sit up comfortably in bed. Part of our new Modern line, this bed combines white and natural wood to create a warm, two-tone design that matches perfectly with your neutral furniture and room decor. This heavy-duty bunk bed can support up to 2,000 lbs. per sleeping surface, while tall 16-inch guard rails on the top bunk keep sleepers safe and secure. The straight ladder rests flush against the bed to save valuable floor space and has wide, grooved steps to make climbing up easy. Perfect for guest rooms or shared spaces, this bed can be reconfigured into two queen beds or turned into lofts as kids and families grow.
