OK. At first I borderline hated the purple mattress. I'm under 130 pounds, so the floating effect they warn of is 100 percent accurate. For a few weeks I hurt like heck (but not really any worse than the pain I was experiencing from my old Tempur pedic, just different). Trying to find the right pillow was frustrating (I'm mostly a side and sometimes a back sleeper). I tossed and turned like crazy at night, never getting into a deep sleep. I finally found a pillow that worked for me, and at around three weeks, my back pain almost completely disappeared. But my arm/shoulder pain and the falling asleep feeling in my arms persisted, keeping me awake at night. Then, one day I laid on my husband's side and noticed the bed was significantly softer over there. I decided to rotate the bed head to foot so that I was now on his side (yuck, my head is where his feet were). It was softer and more cozy, but my back pain returned for a couple of days and I was ready to throw the bed away and try a different mattress. After a few days though, the gimpyness went away and slowly I started sleeping better. Once I got more sleep, everything started improving and I started falling in love with the bed. After a couple of months, we've officially decided to keep it and have even bought a second set of cotton sheets as opposed to our stretchy ones. There isn't a significant enough difference to us now that the bed is broken in to pay the extra money for stretchy sheets (you know how hard it is to find good quality Jersey sheets in king sized? That was a pain in the rear). I'm knocking my review down to four stars not because of the adjustment period or the sheet buying experience, but because of two other factors: 1). Our bed is about 3-4 inches shorter than a king sized bed is supposed to be, and 2 inches less in width as well. This is not a deal breaker because neither my husband nor I are very tall, but if we were we would be upset. I did contact Purple and they were willing to trade, but we wanted to wait to see if we were going to keep the bed at all before doing so. Now that we've broken it in, I don't really want to go through all that again. 2) I am a bit afraid of the long-term for this bed because the indentations on mine and my husband's sides are already getting obvious just by looking at them, and are extremely obvious when you compare the feel of them to the middle of the bed. Everyone we have try it out notices a huge difference between the sides and the middle. But, they seem to have a fair warranty, so hopefully if it breaks down badly enough before the warranty ends, they'll stand by it. We're excited for our next future adventure! Purple pillows!
