Description

The OF380 is a polyurethane saddle stool — a saddle-shaped seat that opens the hip angle and keeps the spine in a more upright, forward-working posture, favoured for microscopy, dental-style close work and long reaching tasks. Purchased over 1,715 times to date.

Choose a saddle where staff work leaning in for long spells; it takes a day or two to get used to, then most users will not go back. For a conventional seat, see the 008 or 009; the lab chair height guide covers height classes.

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.

Who uses the OF380

Supplied to analytical laboratories at South West Water. The lab stool range is also in daily use at Imperial College London, the University of Sheffield and NHS Blood and Transplant.

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.
