Don't Know What Gas Cylinder I Need - Heavy Duty

Are you a big person and need a heavier duty gas pneumatic for your chair? Our heavy duty gas cylinder can withstand up to 500 lbs. If it doesn't fit, we offer a full refund. The only cost to you is the price to mail it back!! Works as a replacement gas lift cylinder on most models of the following: Global, Lane, Serta, Humanscale, Novimex, Realspace, Broyhill, Lazyboy Lazy Boy, Sealy, Globe, SC Turnstone, Vogel Peterson, and Suspa. To remove most gas cylinders you use a rubber mallet with wood buffer to bang it through the 5 star base from the bottom. To remove the shaft from the mechanism under the seat it, a pipe wrench is commonly used with a "twist and pull" motion. For a stubborn cylinder shaft in the mechanism, you can try applying a little lubricant, but be careful to not lube the whole shaft because then the wrench will no longer grip!
