Description

The 406 is an upholstered desk-height cleanroom chair — the seated partner to the 405, for controlled environments, QC and inspection desks around 720–750 mm where comfort is wanted alongside a wipe-down build. Purchased over 1,698 times to date.

For standing benches around 900 mm, specify the bench-height 405; where the regime demands a solid PU seat with no upholstery, see the 402. The lab chair height guide confirms the height class.

Seat materials

Available in wipe-clean Vinyl or Xtreme Fabric (100% recycled), both included in the price. Vinyl is the usual cleanroom choice; see the full colour and materials range.

Feet or castors

Feet and castor options are selectable above. Castors carry a price uplift — soft-tyre castors are recommended for hard or vinyl flooring, and lock-off or lock-down castors hold the chair in position where it must not move.

Accessories

Available to order with a seat slide (adjusts seat depth for taller or shorter users), adjustable arms, ring arms (better where fixed arms would foul the bench), lumbar support or seat tilt. Priced individually — see the accessories page or ask on your quote.

Who uses the 406

Supplied to controlled environments at Guy’s & St Thomas’ NHS and Urenco. The cleanroom range is also in daily use at McLaren Racing, Roche and Baxter Healthcare.

Ordering

Purchase orders accepted, VAT invoice supplied. Volume pricing from 4 units. Delivery included to mainland Britain. UK support and spares available — we have been supplying laboratory and technical seating since 1986.
