I've been researching to buy a bed for some time since my old pillow top bed was way overdue to be replaced. I actually slept in every other room other than my bedroom simply because I didn't want to wake up with lower back pain. I've spent a lot of time researching and going to mattress stores in search of a new bed. I knew I was going to buy a bed in a bed mattress but needed to determine what type of mattress to get. I've looked at so many mattress to include tuft n needle, amerisleep, sealy cocoon, nectar, bear, ghostbed, Casper etc. I'm a combo sleeper (back/side) and do not like to sleep hot. I have slept on memory foam and pocket coil mattresses which I have in my other bedrooms. I enjoyed the pocket cool mattress for the back support and coolness however I did not have as much support for my shoulder when I slept on my side. I enjoyed the comfort and support of the memory foam mattress however I did notice it was slightly harder to move around and slept a little warmer than the pocket coil. During my research, I came across purple and noticed it appeared to sleep cool, was responsive, and still offered support. One of my biggest concerns is sleeping cool as the summer months get extremely hot and sleeping cool is extremely important (my last bed, a pillow top, slept extremely warm). One thing that helped push my decision was watching a video on the purple mattress where they used a pressure mat to show where the support was. There was a big difference in pressure relief compared to some of the other mattresses I was looking it. I have read mixed reviews on the purple but after all my research, I decided to pull the plug and get one since after all I could return it if I didn't like it. After getting bed and lying on it, I noticed it was responsive yet supportive. When I laid on my back, I felt as if I was floating on the mattress however when I turned to my side, I sank in a litttle and felt support in my hips and shoulder. For about the first week and a half, my wife and I woke up with slight back pain and I was extremely disappointed because I thought I really wanted to love this mattress. I told myself I needed more time to get used to this mattress and I was right. I absolutely love this mattress and I have gotten probably the best quality of sleep I've had in many years. I literally dream every night which was unheard of with my old mattress. It sleeps extremely cool for which I am very happy. The only downside I would say is that I wish there was a little more shoulder support when I sleep on my side however I still sleep great (I didn't want to spend a lot more $ on the newer purple mattresses which are very expensive). Overall extremely pleased with my purchase and I would definitely recommend giving this mattress a try.
