I bought a White Dove Haven queen-size mattress from a local furniture retailer. Queen size mattresses are supposed to be 60x80 inches. Once the mattress was in my home it looked small so I measured and it was less than 58X78. So I called the furniture retailer, who put me in touch with the White Dove rep, Dennis. After exchanging voicemails Dennis called me and said 58X78 was within their tolerances, and much like a 2x4 is not really a 2x4, a White Dove Queen size mattress is smaller than 60x80 and there was nothing they would do to provide me a 60x80 mattress. Aside from that issue, he was disrespectful, refused to tell me who his supervisor is, and hung up on me. In my opinion, that is unprofessional and poor customer service.
