Easy to assemble about 40 minutes.  It is a very light weight wood/cabinet , be sure to use strap. The room is wonderful , 1 fixed middle and 3 adjustable.  Could probably fit 1 or 2 more if pegs are moved. So I have only installed 1 of the doors, needs minor adjustments but went ok. I am very satisfied with this purchase exactly what I wanted. Also love that I can paint or stain what ever I want! I recommend this product.
