I am extremely upset. I ordered this mattress as part of a birthday gift for my son and when I opened the box I discovered they sent a twin size instead of the full that I ordered. When I contacted customer service I was told they would email me in 1 to 2 business days. Well of course it’s Friday night and now my son will not have a bed for the weekend or foreseeable future. I am completely disappointed especially this being my first time using Wayfair.
