Featuring a contemporary armless design and commercial quality construction, the Bush Furniture Architect Mid Back Ribbed Leather Office Chair is a perfect choice for use in today's homes and professional workplaces. Soft cushioning on the seat and backrest provides exceptional comfort for a variety of tasks, from gathering with coworkers around a conference table to just browsing the web at home. The tilt mechanism rocks back from a point over the center of the chair and can be set to a custom rate and ease of recline by turning the tension knob located underneath the seat. A convenient lever instantly adjusts the seat's height to meet individual preference and is also used to lock the tilt function so that the chair is fixed in an upright position. Five dual-wheeled casters and a 360 degree swivel base provide complete mobility and range of motion for multitasking and collaboration. The low-profile armless design saves space in compact areas by allowing the computer chair to slide all the way under a desk or table. A heavy duty nylon base provides a strong foundation for the chair to support up to 275 pounds. Smooth bonded leather upholstery features an attractive ribbed texture and coordinates with a variety of workspaces. This armless swivel chair with wheels is tested to meet ANSI/BIFMA quality standards for safety and performance and is backed by the Bush Furniture 5 Year Manufacturer's Warranty.
