Its fairly easy to assemble IF you follow the instructions and are gentle with the parts Mine has never torn even though I use it every for at least 10 hours per day. the height piston lasts maybe for 5 months on the inside. And it is annoying to height adjust every 5 minutes but this is a low cost chair. Overall not a bad chair for the price.
Its okay, but......
