Sofa Steiner velvet brick

Vintage sofa of the brand steiner. Brick color, velvet. Basically it unfolds in bed but I can not, the system is too heavy for me. It is a sofa that has never been used, it has remained sheltered for years. Exterior in super condition, no trace of wear, nor sagging of the seats. Inside on the other hand the foam begins to crumble (it was cleaned when I recovered it). Total measurement of the sofa: Total length: 1m65. Height from the bottom to the top of the seat: 66 cm. Seat width: 56 cm. Measurement of an individual seat: Seat cushion: 82 X 56. Backrest cushion: 82 X 54. Seat height: 35 cm. The cushions stay well in place thanks to scratches. The sofa is quite heavy.
