hm42 Prism


Ideal for public areas, short-stay and gallery seating, Coleman’s Prism/hm42 is a generously-proportioned modular bench system based on the plan-form of a half-hexagon that can be arranged and linked in endless permutations. The two alternative heights enable ‘perching’ as well as sitting, and the high unit also provides a back or armrest for the lower piece.

The units can be covered in a wide choice of fabrics and hides, and multi-tone upholstery is available - side and top panels can be upholstered in different fabrics.
