at this point I can only give a 1 as item was received in a timely manner. I checked &  looked like no parts were missing, however 1st wayfair pro tech never c showed up or even contacted me  but  somehow I received multiple messages requesting I rate the assemly.Rescheduled Tech came two days later.He was very prompt and professional. However he noticed that one of the rails was not for the Bed I purchased.
Still waiting for correct part to be shipped . I will update once Bed has been delivered and hopefully  tech pro will be able to assemble.
