Excellent replacement

Great replacement cartridge and was easy to install.

works great on my chair as a replacement the Piston that was originally with the chair was only rated for

Great Replacement

I HATE this replacement

Fortunately I had a dimensioned drawing of the factory cylinder and the Amazon listing for this cylinder had sufficient dimensions to determine that this would be a perfect replacement.

Solid durable replacement.

Perfect replacement for broken piston.

Fit perfectly and works as it should and arrived quickly
