The instructions are very vague and you have to figure some things out for yourself. The side pieces have a recess in them so you can lay the back piece flat inside the recess but the instructions do not indicate it matters how any of the pieces lay so just be prepared. Other than that the piece was fairly easy to put together. The actual depth of the unit that can be used as storage is just a little over 10 inches. Mine came wrapped to the hilt but one of the doors still had a big scratch it in at the bottom. Overall not a bad piece just don't expect perfection.
