Rounded rolled arms with pronounced piping give this black sleeper a fuller, more formal appearance than the straight-arm models in the series. The smooth leather-look surface continues across two seat cushions and two generous back cushions, producing a substantial closed profile suitable for buyers developing darker apartment or executive-lounge selections.

The mattress platform folds outward from inside the sofa and rests on a thickened metal frame with anti-rust coating. Four configurations provide 110, 120, 140 or 160 cm sleeping widths at a common 190 cm length. A 12 cm pocket spring mattress is specified independently from the upholstered seat, so the opened form remains clearly identifiable as a mattress sleeper rather than a flat cushion conversion.

Velvet, chenille or scratch-resistant leather-look upholstery can be reviewed with color and quantity. The sofa frame uses polished solid wood battens and multilayer plywood with 35-density non-spliced foam. Buyers should approve piping alignment, loose-cushion fit and the full fold-out sequence before repeat production.
