Design & configuration

A closer look

Two base options share the photographed pale back and grey padded seat: four fixed legs and a continuous sled frame. The rear support detail is shown separately from the front seating profile.

Compare each base on the same page, with its own front, side and rear photographs. Confirm the floor protection, finish and selected base before preparing a training-room schedule.

D578 uses glass-fibre-reinforced PP seat-and-back components with a split snap-fit connection. The padded seat combines virgin foam with breathable fabric.

Configuration reference. Select the required base, accessories, finish and order specification.
