Zero stars!!!!!! Couriers awful, supposed to deliver last week, to give me 3 hr slot next day....still nothing after numerous calls, emails to wayfair & courier.  Very frustrating & this has happened with two mattresses i ordered, other left down an alleyway to some guy in my village.  
Customer services agree awful, tell you they'll contact you that day and never do...i am still waiting for this mattress & cannot believe the gall of asking for a review!!!!! Steer clear, i am utterly appalled.
