Was very easy to put together. From the moment it was out of the box the car started playing with it. Very small footprint for the size. Gives the cat a place to escape from the dogs. Probably took me 20 minutes to put together. The instructions are just pictures but we're really easy to follow. It arrived in one box and the cat is having fun playing with the box as well. Lol

Pros: Easy to assemble, great value, and keeps the cat entertained. 
Cons: Would be nice if there were multiple colors to choose from.
