Broad rectangular arms frame this black sleeper with a deliberately low, architectural outline. Their flat top surfaces contrast with the softer pair of back cushions and small side pillows, while the uninterrupted front rail keeps the closed elevation clean. This visual structure suits furniture brands that want a darker mattress sleeper without rolled or flared arm details.

The sleeping system folds forward from below the seat on a thickened, anti-rust-coated metal frame. Four documented sizes provide sleeping widths of 110, 120, 140 and 160 cm, each 190 cm long and paired with a 12 cm pocket spring mattress. Corresponding sofa widths run from 170 to 220 cm.

Polished solid wood battens and multilayer plywood form the specified sofa frame, combined with 35-density non-spliced foam. Buyers may select upholstery, color and a listed dimension pair. During sample approval, the square arm lines, cushion spacing, washable removable covers and mattress deployment should be reviewed as one complete reference.
