I was going to give this 3 starts for the difficulty I had putting them together but then I figured out a shortcut. I DID NOT use the tiny allen wrench that was provided. Instead I used a screw driver allen wrench and had a much easier time. While using the allen wrench at first, the screws would not go into the holes so i thought they were not lined up properly and I would not be able to assemble the chair. I was able to get them all together fairly quickly after using the screw driver. The reason I am giving it 4 stars instead of 5 is because they are not as heavy as I was hoping, but they seem sturdy. I ordered them because a friend of mine has chairs that are listed as 20lbs online and are fairly strong and sturdy. These were also listed as 20lbs each but just seem light. We will see how durable they are once we get more use out of them and have company over.
