Ordered 2 sets. One box had broke open in shipping. Someone taped it back together but the bolts and Allen key were missing.  Called manufacturer. They said they would ship the hardware to me. 3 weeks later contacted them again this time they say to contact Wayfair. I decide to see if I can find bolts locally. I did but the bolts that should have come with it are too short so I got longer bolts. The stools are good so far. Hopefully they will last. Needs better packaging when shipping heavy items.
