I am writing this review after only one night on my Purple mattress... I AM IN LOVE!!! A little background on me. I am a single (mention that cause I sleep alone not for dating purposes lol) 30 y/o male, 5'8", 190 lbs (more muscle than fat) stomach sleeper. I am an Army Vet and an RN in an ER (more on that later). First, to address the picture of the Purple blade. I don't know if I was just excited and wasn't taking my time, but I got the under portion (not pictured) of the safety blade under the plastic and as I was straddling the mattress I was cutting down and between my legs, as I was going along the plastic piece broke and the blade went right into my thumb!!! :( Now, I am not blaming Purple for this. I should have been cutting away from my body and did it a little safer, but I still wanted to put that in the review so future buyers can learn from my silly mistake....and so you don't get blood on your pretty new white mattress (luckily I didn't). Anyways, the Army, working in healthcare, being a stomach sleeper, and when I was overweight (260 lbs) has put a number on my lower back. I started working out more and lost over 70 lbs and STILL had back pains. So I started doing research for a new mattress. I previously slept on a cheap no-name inner-spring mattress that was several years old. I found that what I needed was a firmer mattress that maintained my spinal alignment - enter Purple. Love at first sight (lay down). I haven't had a full night of straight sleep in years!!! I constantly have to try to lay on my back with a pillow under my thighs to take the pressure off my lower back (a position that is IMPOSSIBLE for me to sleep in) or lay on my side with a pillow between my legs; eventually going back to my stomach and waking in pain. Last night was probably the best night of sleep I have ever had!!! I will say that I am still a little achy and it is my thought that I will still need some time for my body to adjust to the mattress as my spine has been out of wack for years. Purple even stated this in its instruction paper that some people need up to 30 days to fully adjust, so I am optimistic that the pain will subside completely in that timeframe. Purple is exactly as advertised and has exceeded my expectations. The mattress cradles my body perfectly in the correct areas without a feeling of sinking, stays cool (I also sleep hot), and just feels like my spine is in perfect alignment which creates it's famous "floating" sensation. I just cannot state enough how happy I am with this mattress and I would highly recommend it for stomach sleepers. I saw Purple's other options with a taller purple grid and all the other bells and whistles, but I stayed with OG mattress as it is my interpretation that this was the firmest options they offered. Very satisfied with my selection. I hope this review was helpful. Definitely recommend doing your own research, read reviews, watch videos via YouTube with multiple people, and see what is the best option for you (and your spouse if applicable), but I definitely recommend Purple for my fellow stomach sleepers and it even feels great in the other positions. If you're considering it, go for it! You spend 1/3 of your entire life sleeping. Treat yourself!!! Oh and my dog loves it too lol
