This multi-functional task office chair will give you an edge on comfort with its design and adjusting capabilities. Chair is attractively designed with its two-tone mesh upholstery that is seamlessly outlined in the seat and back of the chair. High back office chairs extend to the upper back for greater support and relieve tension in the lower back, preventing long term strain. The infinite-locking back angle adjustment lever changes the angle of your torso to reduce disc pressure. The multi-tilt lock mechanism rocks/tilts and locks the chair in infinite positions while the tilt tension adjustment knob adjusts the chair's backward tilt resistance. Chair easily swivels 360 degrees to get the maximum use of your workspace without strain. The pneumatic adjustment lever will allow you to easily adjust the seat to your desired height. The height adjustable armrests take the pressure off the shoulders and the neck.Features:Finish: Black and GrayContemporary Task Office Chair with ArmsBlack and Gray Mesh Upholstery with CAL 117 Fire Retardant FoamHigh Back Design, Height Adjustable Padded ArmsTriple Paddle Control MechanismInfinite-Locking Back Angle Adjustment helps reduce disc pressure by changing the angle of your torsoMulti-Tilt Lock Mechanism rocks/tilts and locks the chair in infinite positionsTilt Tension Adjustment Knob adjusts the chair's backward tilt resistancePneumatic Swivel Seat Height AdjustmentHeavy Duty Nylon BaseDual Wheel CastersSpecifications:Product Dimensions: 43.25" - 49" H x 27" W x 23.75" DProduct Weight: 48 lbsSeat Dimensions: 19.5" - 22.5" H x 21.5" W x 19" DBack Dimensions: 25.5" - 27.25" H x 21" WArm Height: 25.75" - 32.75" H from floor; 6.75" - 9.5" H from seatRecommended Location: IndoorRecommended Room: Office
