Quite fashionably flexible, to go with a variety of styles.  In general, easy to put together.  However, the directions aren’t specific enough on the way to orient the shelves. Therefore I had to take everything apart and turn one of the shelves around, so that the backs of all shelves lined up.  Other than that, it wasn’t a problem to put together.  On one of the sides, which was assembled before shipping, a dowel holding the cross strut was broken.  I glued it together before assembling the whole unit. That, and the fact that one of the corners on the top piece was slightly damaged, is why I gave it four stars.  There should be better quality control.
