Tango is a sofa produced in both fixed (W 223 cm or 270 cm) and modular versions. It has a double-function transforming system, with retractable, foldaway double bed. Both versions of Tango have either fixed or sliding seats (which move forward by 20 cm). The model is made up of modular elements both with and without armrests, corner components with built-in storage compartments, end components with movable armrests and chaise lounges of varying dimensions. The sofa is also produced without the convertible bed system in the sizes W 190 - 223 - 270 cm. The seat cushions are filled with natural down and feature non-deformable foam inserts in differing densities. The back rests are filled with piumafill and have an internal lining in cotton, while the rear roll is padded with non-deformable foam. All covers can be removed. The double bed is always ready to use and features the innovative CF97 slatted bed base. The structure is made from aluminum extrusions, with the bed fitted with an integrated adjustment system. The bed is opened and closed using a handle - which is either fixed or extendible - positioned on the front shelf. When opened, this front shelf pivots to become the support for the bed; the opening system means that objects on the shelf do not have to be removed.
