Replacement Gas Lift for Office and Gaming Chairs

This WORKPRO cylinder replaces worn or leaking pneumatic lifts in rolling stools, gaming chairs and standard office chairs. It provides smooth vertical travel and supports full 360 degree seat rotation once installed. The unit is certified under SGS and LGA testing standards for durability.

8 Inch Stroke Extends Seat Height Range

The 8 inch stroke raises the seat 2 to 4 inches higher than conventional cylinders, giving a compressed length of 14.3 inches and an extended length of 22.3 inches. Assembled chair height typically falls between 20 and 28 inches, suiting users who need a taller sitting position.

450 lbs Weight Capacity Determines Suitability

The cylinder is rated to support 450 lbs, making it appropriate for heavy duty use and larger users. Buyers who need a higher load rating or a shorter stroke for low profile seating cannot use this model.

Questions about this item

How often will the WORKPRO gas lift cylinder need replacement under normal office use?

The manufacturer states a 5-year replacement period for any non-human quality problem, indicating the cylinder is designed to last at least that long before service is required.

What is the first limit reached when the cylinder is cycled continuously at its 450 lbs capacity?

The 8-inch stroke defines the travel limit; once the piston reaches the fully extended 22.3" or fully compressed 14.3" position, further movement stops.

Does the cylinder generate noticeable heat or noise during all-day height adjustments?

The gas-spring design operates silently with smooth rise and fall, and no heat build-up is mentioned for continuous daily use.
