I gave this desk a 4 star rating simply because it arrived without any assembly instructions. Wayfair customer support had one set of instructions on hand in pdf format. However, the manufacturer had made changes with certain mechanical parts and therefore the instructions required updating. Wayfair customer support put us in touch with the manufacturer and they emailed us the correct assembly instructions. I do like my desk and the mechanical parts work very well. I do recommend this product to others because, overall, I am very pleased. It was just the delay in obtaining correct instructions I wasn't a fan of. Luckily I wasn't in a big hurry to get it assembled for immediate use. You can't go wrong with Wayfair customer support - they are awesome!
