My husband and I put the bench together relatively quickly--it helps to have two people to line up the holes as you build. 

Our chief problem is that the painted wood emits a horrible odor that gave me a splitting headache the minute I opened the box.  As the box appeared to have been opened previously, I'm assuming the previous owners returned it due to the fumes.  The top of bench also has a bashed corner where the paint has been scraped off. (See photo.)  

Since other reviewers don't mention an odor, I'm hoping Wayfair will send us a replacement bench that I can tolerate keeping in the house.
