Common storage options include pull-out trundle beds, multiple under-bed drawers, hydraulic lift-up under-bed storage, built-in headboard shelves, and side lift-up storage drawers.

Classic-style beds are commonly offered in twin, full, queen, and king sizes.
Frame materials commonly include wood (pine, plywood, rubberwood, MDF — medium-density fiberboard) and metal (iron). Upholstery textiles commonly shown include linen and polyester.
