I researched mattresses for awhile before deciding that I would purchase the Purple mattress. My wife and I are extremely happy with our purchase. There are four things that we noticed about our recent purchase: 1) We are most happy with how cool this mattress sleeps. With our old mattress there were nights where we would wake up and have sweat through the sheets. That hasn't been an issue at all since we got our Purple mattress. If temperature is something that you are concerned about, I highly recommend this mattress. 2) The very first night I could tell an immediate difference with the support the mattress provided. I sleep on my side/stomach, and with our old mattress I would get into bed, and then get into my sleeping position. For the next few minutes I would have to slowly start to relax as I would always feel pain in my back as my body slowly got used to my sleeping position. The first night with our Purple mattress my body was able to immediately relax with no pain at all. That was as great surprise, and helped me realize I chose the right mattress. 3) During the first two weeks of sleeping on the Purple mattress, my wife and I both experienced waking up numerous times throughout the night, up to 10 times a night. We were able to adjust, or roll-over and go right back to sleep, and we didn't feel like we were losing sleep. We both just noticed that we were experiences similar situations. This only occurred during the first two weeks, so I believe this was just part of adjusting to the new mattress. 4) The last thing we noticed about our mattress was our dreams. During the first 4-6 weeks, we realized that we were both having more dreams, our dreams were more vivd, and we were able to remember them with great detail in the morning. We found this strange, and actually laughed about it. It also made for good morning conversations while getting ready. I'm not saying this is specific to Purple, but the fact that we both experienced the same thing and the same time leads me to believe it has something to do with the new mattress. Our trial period is coming to an end soon, but it doesn't matter as we have no intention of returning this mattress. Since our purchase, I see that Purple has now introduced additional products including a pillow. With how cool the mattress sleeps, I may have to try out the pillow as I constantly flip my pillow in order to get the cool side. I am also looking to purchase a seat cushion for my father who has undergone two back surgeries and is scheduling a 3rd later this year. He was in town when our mattress was delivered and he was intrigued with the small samples that arrived with the mattress. Extremely Satisfied Customer.
