We ordered the Queen size version of this bed right before the holidays. The first bed we received had some parts that didn't fit together so Wayfair sent us replacement parts, but those also didn't work. To resolve the problem, Wayfair sent a replacement bed. The second bed was easy to put together and we are very happy with it! 
Although the process was a little frustrating and time consuming - Wayfair customer service was  responsive and helpful and got the problem taken care of as quickly as possible.
