Description

The A12 is our Budget polyurethane bench-height lab chair — the chair universities and schools order by the roomful. A wipe-clean PU seat and backrest with adjustable footring for standing benches around 900 mm, at the most accessible price in the range. Purchased over 2,185 times to date.

Choose the A12 for teaching labs, multi-bench fit-outs and anywhere numbers matter. Where staff spend long spells seated, step up to the Deluxe 001 or the upholstered 005; for seated desks, specify the desk-height A13. The lab chair height guide confirms the right class.

Seat

A moulded polyurethane seat — solid, seam-free and wipe-clean. It tolerates routine laboratory cleaning agents and shrugs off knocks, spills and daily wash-down, which is why PU is the default choice for busy shared benches. Ideal for teaching labs where seating is shared by hundreds of students a week.

Feet or castors

Supplied with feet as standard, which is usually right for a tall chair at a standing bench. Castors are available at a price uplift — specify soft-tyre for hard or vinyl flooring, and lock-off or lock-down castors where the chair must stay put. Consider the safety requirements of your working environment before choosing castors on a high chair.

Accessories

Available to order with ring arms, adjustable arms or seat tilt. Priced individually — see the accessories page or ask on your quote.
