Design & configuration
Promise brings OMC-1 mid-back, OMCH-1 headrest and OMC-1-F visitor chairs together on one family page. Compare the photographed configurations before selecting a chair for each room.
Start with the seating role: a mobile chair for individual work, a headrest model for a higher-back profile, or a visitor configuration for meeting and guest seating. Each linked page provides the details and imagery for that configuration.
The PP back frame is reinforced with 15% glass fibre. The upholstered seat uses 60 mm high-density foam.
Compare support features on the model pages rather than treating every chair in the family as an identical specification.
