Received this mattress 3 days after ordering. (We live in AZ) Amazing. Comes highly compressed -- in less than 4 hours it was queen size and nearly ready to go. Has some odor from being compressed and packaged -- odor was gone within 2 -3 days. We used an air disinfectant on our sheets while they were on the mattress, and it seemed to help. Sooo comfortable. Seemed too hard at first, but within one hour had warmed with body heat, and became perfect. My husband and I both feel better, wake more refreshed, and just generally love this mattress!
