The inspiration for Maxwell "was to take a traditional shape and make it fresh," says Apartment Therapy founder Maxwell Ryan, who co-created the design with us. That means you'll enjoy a custom bed that's "comfy, cozy, and approachable," with a curved shelter headboard in a classic wing profile shape and a discrete lift up storage option for spaces big and small. Box springs are optional with Maxwell's slat support system. Not compatible with adjustable frames.
