It is too early to tell whether a product such as this is good or not. At this time the chair works and looks as advertised. I do not know if the hydraulic mechanism will work as well in two years but I hope that it does. (I am happy it is not “bonded” leather as my experience tells me that in 2 to 3 years little pieces of the “leather” will start tearing and falling off.) At this time I would recommend the chair. A better time to ask would be in 2-3 years from now.
I gave it a 3star. As you tighten the bolt under seat the entire bolt receiver rotates therefore the seat is not tighten properly. If it wasn't for that I would recommend to buy.
Nice chair! Instructions could be better and an link for online video would be helpful. It wasn’t clear enough!! It was the hardest if the 3 chairs I own to put together!
