HX-CHR-015 is organized around its frame: long arms, angled rear posts and a low seat establish the lounge posture before upholstery is added. One configuration uses softer loose cushions for a relaxed hotel or apartment mood; the other uses a more fitted, channelled pad that feels tailored and graphic. Since the frame geometry and seating purpose remain consistent, these are variants within one series. The open sides keep the chair from blocking sightlines in lobby groups, and the pronounced arm rails make it easy to coordinate with similarly linear coffee tables. Specification should begin with the preferred cushion character, then address upholstery, frame finish, seat firmness and the depth required for the intended stay.
