OK so yes the box is heavy when you get it so be careful. This took me and my husband 2 hours and 15 minutes exactly to put together. We timed it. He did the manual stuff, I read the directions and gave him the pieces and screws. Everything is marked with a letter so no confusion. Comes with all the hardware and an allenwrench. You will need a Phillips screw driver. I don't suggest using a drill, but that's up to the individual.Didn't really have to adjust the doors. They are fine for me. The shelf is adjustable so if you're putting appliances in it to store and they are tall, you can easily adjust the shelf.The wheels are thick hard plastic. Now I'm 5'5" and the top hits me right above my hip bone. So it's the same height as a standard kitchen counter.All and all, I'm extremely happy with it!
