Other reviews stating the assembly instructions are bad aren't kidding. The knob is also super cheap looking plastic - a big no no. No predrilled holes means you need an electric drill (which I had) but led to a rickety structure. I bought 2 of these and on the 2nd one the screw of the leg broke off and I need to try to get a refund on this! Don't buy. Not up to the standards I expect and have enjoyed from Wayfair.
