Not impressed.  Very light wood - probably pine or poplar.  Not likely to last long.  I will probably need to coat them with something to preserve their lives.  Very long assembly.  Each chair has over 80 screws, 18 dowels 10 bolts, 6 nuts, and 33 pieces of wood.  Directions use minimal and inadequate (imho) directions.  It took me about 3 hours per chair, using Phillips head screwdriver and a pair of pliers.  And I am used to assembling furniture.  If you are new to it, figure at least an extra hour.  My wife complained that the chairs are not comfortable, so I need to buy some more lawn chairs.  These were pretty much a waste of time and money, from my perspective.  Not recommended.
