I bought 2 of these for my craft room.  The quality is very good.  I love the top because it has a wood finish.  The shelves can be placed in any design  that fit your needs,  I have different size baskets and boxes that I use to store my supplies for my many crafts. (sewing, scrapbooking, jewelry, and doll house items)  It is a heavy piece so you need 2 people at some point when you are  putting it together.
When I was putting the 2nd one together I used a folding table that has 3 different height positions.  I used the lowest height and placed the table against a wall so it wouldn't fall off  and I put it together on the table so I didn't have to be on my knees for the entire time. It took longer to put together because I made some stupid mistakes which was my own fault.  It was well worth the time and money I spent on them.  I have received a lot of great compliments on the quality and look of the credenza.
