I am with a lot of other reviewers who found this hard to put together. The reason is that the pieces are not all 100% symmetrical and so when one side fits, the other doesn't, causing the whole thing to easily fall apart in the process. Two suggestions: 1. work with 2 people-- don't even try to put it together by yourself, and 2. Use a work bench to raise it off the ground once you've got the base set. That will allow you to connect the sides pretty easily. If you are trying to connect the sides while it is on the ground or while you have laid it down, forget about it! Once you've got the first side on, the rest is a piece of cake. The final product is very nice and it a good size especially for the price.
