• Extra-Wide Adjustable Height Range: Enjoy a generous 5.5-inch (140mm) lift range, from a minimum of 11.2" to a maximum of 16.7". To ensure a perfect fit, please measure your old cylinder before ordering, as the installed height may differ and result in a higher seating position than expected.

Supporting up to 1000 lbs without wobble, leakage, or failure, it is engineered from thickened steel with an anti-explosion decompression design, making it the ultimate office chair cylinder replacement for long-term peace of mind.
• 360° Swivel & Ultra-Smooth Lift: Thanks to precision sealing and gas-powered shock absorption, you’ll experience silky-smooth height adjustments and quiet 360° rotation. No creaks, no jerks—just seamless movement and a more peaceful workspace
• Ease of Installation: Simply remove the protective cap (if present), remove the old pneumatic lift (rubber mallet recommended), insert this new office chair piston, and you’re done—no extra screws or complex steps required.
