Design of the backrest is a distinctive feature - it may be combined in many ways due to different shapes of frame and shell, as well as colours and fabric textures:

• Mesh: frame with transparent mesh

• Mesh Plus: frame with 3D diamond pattern fabric

• UPH/Plastic: shell with plain woven fabric

• UPH/Plastic Plus: shell with 3D diamond pattern fabric 

Denuo is up to date with the colour trends. Monocolor set are possible to create thanks to selected colours of fabrics which perfectly match to the colours of of backrests (white, light grey and black) as well as components such as armrests, bases and castors.
