The TriHeight platform is a SKU-reduction tool. The seat box, base and seat cushion are identical across three versions; only the back changes, at 33.5 in (85 cm), 43 in (110 cm) or 53 in (135 cm). A round metal cap at the back-to-seat junction marks the interchangeable joint.
What it changes. The factory builds one core component in volume and fits the back each store needs: low backs for quick-turn zones, mid backs for main dining, high backs for semi-private areas. Fewer unique parts means more consistent quality and simpler spares.
Construction. Hardwood and engineered-ply seat box and backs; 47 in (120 cm) module length; 18 in (46 cm) seat; 22 in (56 cm) depth. Backs bolt to the seat box through a concealed bracket.
Rollout notes. Store formats specify back height by zone on the floor plan; spare seat cushions are common to all three versions.
