Frames are craftsman-built using cross-directional hardwood laminate. Upholstered surfaces contain dense foam made from partially plant-based material, padded with poly fibers. Our Banks Performance Fabrics are extremely durable and resist stains yet remain beautiful and soft to the touch. Mariel beds feature classic turned-style legs with a hand-applied ember finish and a beautiful channel stitched detail bordering the silhouette. Bed frames accommodate for variances in mattress sizes and allow bedding to be tucked in. Queen beds feature a frame cavity measuring 61.5" w x 81.5" d x 2" h. King beds feature a frame cavity measuring 77.5" w x 81.5" d x 2" h. Mariel beds do not require box springs.
