Ethos in the king configuration is 82 inches wide, with a clean tight-upholstered look that doesn't telegraph "sleeper sofa" across the room. The medium-density seat foam and consistent proportions across the Ethos line mean it fits into a formal living room or a primary bedroom without looking like a compromise piece. The bed, when open, is the same size as a standard king.
The Nest function drives the conversion. It's a dual-motion mechanism: the seat and the back each move as separate components, which is architecturally different from the single-hinge pull-out that most people picture when they imagine a sleeper sofa. You're repositioning two panels rather than wrestling with one. Manual operation, no power required. Ethos has been built around this mechanism across its full range, cot through king.
A king bed at 76 inches wide by 80 inches long. That's a real king, wider than what some brands label "king" on a sleeper. The mattress is CertiPUR-EU certified cold-cured high-resilience foam. Seat foam is 2.2 pounds per cubic foot, medium density, tight to the frame. It's a firmer seat than some of the softer-foam frames in the Luonto catalog, better for everyday sitting, and the foam density holds up over time.
FSC-certified birch plywood and PEFC solid Nordic spruce frame. Designed in Finland, made in Europe. Back cushions are loose and fiber-filled, with up to 40 percent recycled fiber. Fabric choices run grades A through E; leathers from 1000 through Prescott, over a hundred options in total. A Lux Upgrade adds a center support leg under the bed and full upholstery on the back and sides. Four to six weeks, made to order.
Choose this over the Ethos Queen if you need the full king width for two adults sleeping comfortably. The Fantasy King Sofa uses the Level function (a single-motion, assisted-open mechanism) and runs slightly wider at 86.5 inches; pick Ethos if you prefer the Nest's dual-motion conversion and the tighter 82-inch footprint.
