I gave it 4/stars because I really like this bar stool and it could be a 5/star but the first set I received the hydraulic would not connect on either. I called  way fair and they came thru the customer service lady gave me a choice to have full credit  returned or they will send  another set. Well I opted for another set and both are working very ice.. I have to donate the other 2as when these are assembled they can not be disconnected to return. Way fair did right  and I will continue being a customer .very please with the service and product .thankyou wayfair....
