Tall arms flare subtly outward at the front, framing three loose back cushions and a clean two-part seat. This wing-like outline gives the black sleeper more vertical definition than the low soft-arm options, while the smooth front rail keeps the body visually controlled. A small metallic detail on the outer arm is visible but does not dominate the design.

The mattress frame folds out from inside the sofa to create a separate 190 cm-long sleeping surface. Four compact sofa widths from 150 to 200 cm map to bed widths of 110, 120, 140 and 160 cm. The independent mattress is specified at 12 cm thick and sits on a reinforced metal sleeper frame with anti-rust coating.

Polished solid wood battens and multilayer plywood support the upholstered sofa body, together with 35-density non-spliced foam. Buyers may choose a listed size, upholstery and color. The wing-arm symmetry, loose washable cushions, metal-frame movement and mattress position should all be included in the sample approval record.
