Our newest addition to the bedroom is this fun, modern round bed. Carosello fits a standard queen or king mattress and comes with the two attached swivel nightstands. Covered in durable leather-look upholstery in your choice of white or black. The nightstands feature a black-stained wood top on a chromed metal support. No box spring or foundation is required, as the mattress is supported by a series of wooden slats.
