The directions are very straight forward and theoretically it should be easy to assemble; however, the little plastic clamps (piece E) are too small to clamp around the poles/legs (pieces A,B,C) They just pop off before your able to proceed. And piece E is supposed to keep the shelves (piece D) from just sliding straight down the poles. I've attempted some creative engineering using duct tape, but  the circumference of the poles and the corners of the shelves are not machined properly and all vary in size. If I am able to get the clamps to stay on, they will not fit into the corner of the shelving unit, which will make for an extremely wobble shelve- assuming I could get that far. I'm going to go to the hardware store and try to find something that will work, if not it's going to be returned and this will be my first and last purchase from Wayfair.
