Follow the instructions!! For those like me, who have put  lot of kits together, we take things for granted. This kit is PERFECTLY laid out, but its very important to follow the instructions to the letter. Each packet is numbered and referenced. There is on extra screw in each pack (nice). And this baby is NOT coming apart. Screws, dowels, and her bolts are placed to insure optimum sturdiness. Top shelf has adjustable height. A definite buy!
