Product came quickly.  I ordered 2 chairs only 2 of the 4 bolts came with one chair and none with the other.  Instead of calling customer service and waiting for them to be shipped, we just went to home depot and picked up 8 nut and bolt sets.  They were easy to put together and one person can do it but would be easier for two people as one has to hold the base while the other one puts on the bolts.  But I'm just guessing since I watched my husband do it by himself!! All in all, great product and very comfortable.  I'm thinking about getting a couple more.
