MASTERY MART 14-22 Inch Extra Long Office Chair Cylinder Replacement with Gloves, 8" Stroke Gas Lift, Heavy Duty 1000 Lbs Class 4 Hydraulic Pneumatic Piston, Universal Fit

About this item

This is a heavy-duty replacement gas cylinder for office chairs, drafting chairs, bar stools, and standing-desk seats that have started sinking or losing height. Made from carbon steel and tested to BIFMA Class 4 standards, it supports up to 1000 lbs and holds its set height instead of slowly dropping. The 8-inch stroke extends from 13.97 in to 21.85 in, suited for taller users and chairs needing a 20-27 in seat height range. Measure your current cylinder's length and diameters before ordering, since fit depends on matching both the outer tube and the seat plate socket.

• BIFMA Class 4 rated gas cylinder, holds up to 1000 lbs without sinking over time
• 8-inch stroke: 13.97 in compressed to 21.85 in extended, giving a 20-27 in seat height range
• Built for taller users and tall chairs — drafting chairs, bar stools, standing-desk seats
• Outer tube 2 in (50 mm) diameter, piston shaft 1-1/8 in (28 mm) — check your current cylinder size before buying
• Tool-free swap: knock out the old cylinder with a mallet, push the new one into the base until it clicks
• Rubber gloves included for a cleaner grip during removal
