The bed is incredible! We were hestitant to purchase a bed without testing for firmness in person. The sale price and the fact that anything was better than our current bed over ruled out hestitancy. So happy we did. Great quality and no more back pain after the first night! 
Fast delivery, easy setup and the timeframe to "air it out" was about 48 hrs. No chemical smell. 
Will purchase another bed from Wayfair (or any product) without hesitation in the future.
