I had been looking at this coffee table online for a year before finally deciding to order. [...] I was more then pleased when it arrived.  It was exactly what I had been looking for as a space saver and easily opens when guests arrive.  I was also pleasantly surprised with the quality and to find the table had four tiers (top & three tiers that open).  It's hard to see the four tiers online.  As other reviewers mentioned we also put the bottom ring on upside down and there are no casters...neither are a big deal.  I love my new coffee table.[...].  All and all a great experience.
