I am in love with these chairs!! Both chairs took me about an hour to build total. There are two pieces being the base and then the seat itself that you will have to assemble. There isn’t instructions, but with common sense you just have to unzip the base and then move the two holes to each area that you have to screw in order to anchor the seat to the base. Overall I am so far very satisfied with these and will absolutely be purchasing through wayfair in the future and look forward to what other items this vendor has to offer for other pieces!
