I really like these stools.  They fit perfectly at my kitchen island.  They were easy to put together.  Some of the holes didn't line up perfectly with the screws but they still went in just fine.  They are sturdy and they don't wobble.  I can't determine what they are made of.  It isn't solid wood and might not be wood at all.   The finish has a nice grain texture with a rustic look and they really look like wood.  There are little plastic protectors on the bottom of each leg.
