If your job or hobby requires you to sit for long stretches of time having the right chair is priceless. Big and tall office chairs are designed to accommodate larger and taller body types. This chair has been tested to hold a capacity of up to 400 lbs., offering a broader seat and back width. A mid-back office chair offers support to the mid-to-upper back region. This office chair features plenty of thick, plush padding to provide greater support. Turn the tilt tension adjustment knob to increase or decrease the amount of force needed to rock or recline. Lock the seat in place with the tilt lock mechanism. The waterfall front seat edge removes pressure from the lower legs. The chair easily swivels 360 degrees to get maximum use of your workspace. The pneumatic adjustment lever will allow you to easily adjust the seat. The adjustable armrests take the pressure off the shoulders and the neck. The chrome base adds a stylish look to compliment a contemporary office space.
