Well it is best to get some wood glue to the back side and for cracks abd the topper make sure you set it up on top get something to slide the piece into the top cut line because the corners of the back are not line up the same .I did two so far one to go and one had a chip in the the wood but they come together very easyly.and let the first of the back two dry do the drawers while they dry except the center board way for the dived shelf goes in to drawers are in do to you will have difficulty  putting your hands into it to screw.i had child hands and trust me I did one drawer like this .big mistake lol but all in all there nice.i dont think there priced right thiw because there press wood and plastic and cardboard backs .I would like them to be wood .
