  • This sleeper design allows you to have a larger mattress while taking up less space in the room than a fold-out sleeper. Typical sleeper mattresses are 70 to 75 inches long while the Solid Platform Sleeper mattress is 80 inches long, the same length as a standard bed.
  • Twin has one cushion
  • Queen has two cushions
  • King has three cushions
  • Only available with foam fiber (NaturalLEE) seat and back cushion
  • Lower arms aren’t great for leaning up against, and since the arms are straight, you may need an extra pillow for comfort
  • Seat depth may not  be ideal for taller individuals
  • Firmer seat (solid surface with no “spring”)

  • Good choice if space is limited: narrow seat keeps the scale small, low arms and visible legs keep a room looking airy, narrow arms provide a maximum amount of seating area while taking up minimal space
  • The lower front can collect hair in homes where pets rest against furniture—choose leather or a fabric similar to the color of your pet
  • Regular maintenance will help your upholstery look its best and prolong its life. Rotate seat and back cushions. Vacuum fabric with a soft brush attachment. (Do not use a brush on our Duke fabrics.) Dust leather with a clean, dry cloth.
