Harper pairs a full XL sleeper with a reversible storage chaise in a sectional that reads low and wide: 91 inches across at 32.25 inches tall, with a chaise that extends 62.25 inches deep. The chaise is reversible, so it can be positioned on either side of the sofa body. That flexibility matters in rooms where wall placement isn't symmetrical.
The Nest mechanism opens in two steps: lift the seat, walk it out, lay it flat. Manual operation, no power. The bed deploys out from the wall, and you'll need 84.75 inches of floor clearance behind the sofa. There's a useful half-open position (Luonto calls it Sit and Sleep Simultaneously) where the bed is partially extended while the sofa back is still up, which works for reading in a reclined position.
The full XL bed measures 55 inches wide by 80 inches long. The built-in mattress is five inches of cold-cured, high-density HR foam, CertiPUR certified, rated Daily Sleeper. At 55 inches, it fits one adult well and two if you're generous about space. Seat height is 17.75 inches; seat depth 21.75 inches.
Frame is solid spruce, mortise-and-tenon joinery with birch plywood, FSC and PEFC certified, made in the EU. Over 100 fabrics and over 100 leathers. Four to six weeks from order.
Harper is for the person who wants a sleeper sectional at full XL width without stepping up to queen or king dimensions, useful if the room or the primary user doesn't need the extra 5 inches a queen provides. Compare it against the Martta Full XL, which is also a Flip-mechanism chaise design at the same bed width. Martta opens arm-to-arm and uses the Flip function in one step; Harper uses Nest in two steps and opens out from the wall. Different deployment directions matter depending on how your room is configured.
