I didn't receive any assembly instructions for this item. I had to ask the manufacturer to email the instructions. Once I had the assembly instructions, I spent 30 minutes trying to find the correct piece to start assembly. Once the shelf was 3/4 assembled I realized I had put shelf A on the bottom. I tried to undo my mistake, but the hard ware that keeps the pegs in place wouldn't come out. I decided to under a different portion of the unit. In the end the smaller spaced shelves ended up on the bottom. Oh well, actually worked out for me better this way. But would it be to much to ask the manufacturer to include some key words for assembly?
