Wooden Double Bed with Storage Headboard (Queen-size, Dark Walnut Finish)

Dark walnut-finish wooden double bed, roughly queen size, with a curved headboard that has an open shelf and a small drawer. The base looks like box storage, but that cannot be confirmed from the photo, and neither can the exact dimensions or material (solid wood vs engineered wood). It is photographed in use with bedding, which is not part of the sale, and it is not stated whether the mattress is included.
