Eurotech OSS400 Details

Provide comfortable, ergonomic seating with this Eurotech OSS400-H11 OSS series pewter fabric mid back swivel office chair. Featuring thick seat and back cushions, the chair is contoured and equipped with ergonomic features designed to adjust to suit individual needs. Its waterfall seat reduces the pressure on the back of each user's knees to ensure unrestricted blood flow, helping to keep employees comfortable for extended periods of time. Plus, the seat adjusts in height relative to the floor, seating the user higher or lower based on personal preference or immediate needs. For lumbar support where you need it, the back of the chair is adjustable.

Because the chair does not feature arms, it's perfect for use in settings where employees are frequently standing, reaching, and moving around the office. The chair even sits atop a swivel base with five easy-rolling casters for simple mobility at work stations. Plus, the durable fabric upholstery is easy to clean and maintain. Featuring a 250 lb. weight capacity, this chair is sure to keep your staff comfortable throughout the entire work week. Perfect for any office, this chair is designed for versatile comfort and overall quality!
