The patio set was delivered on time. The first two single chairs were easy to assemble as well as the table. As for the two seated chair that was very difficult to assemble. The placement of the holes to screw in the bolts did not match. I had to purchase larger bolts and I still need to have someone help me with the last bolt. The set is very sturdy, comfortable and roomy. Better instructions would have been a big help. All you got was a diagram,  I'd give it 4 stars
