| The chairs comprise: Good ergonomic posture with back support from an extended frame (1). This is attached to the plastic shell with strong aircraft rivets (2) enabling flexible rotation around the fixing point, reducing stress on the components. |
A seat with rounded edges and without high sides (3), so that pupils can change posture easily, supported on all sides by solid frame below the seat (4). Front legs are angled outwards at the corners to maximise strength in a side-to-side direction as well as forward and back (5). The rear legs (6) are angled backwards to minimise tipping moments.
* size marks 1 & 4 have seat depths marginally too deep to meet part 1 of BS EN 1729 (dimensional requirements). All sizes fully comply with part 2 (strength and stability) Copies of certification available on request.
