Super easy to assemble just read directions a few times and inspect all the pieces , making sure you pay attention to what hole goes with what fastener. There is a right side and wrong side to all the panels. But when you are done, all the connections are tight and you have a very beautiful and practical storage unit. I bought five of them to use in my tiny kitchen got a whole lot of storage and a 6 run of countertop. In 15 of floor space!!! Love Wayfair!!
