I have slept in this mattress for a month, and reduced 90% of my back pain. Having been sleep deprived for months because of a lingering back pain, I think it was totally worth it to invest that much money into a solid mattress.
I have been struggling with poor sleep and snoring for the past 3 years, Ocasionally having lower back pain, thought it was related to testosterone or chemical imbalance but in the end it looks like it was always my mattress and sleep position. I generally would wake up for work at 5:30am and by 10:00am nearly every day would be dead tired and needing a nap. But because I couldn't, I would load up on caffeine, soda or snacks to keep me awake. Once I got home at 3:30pm I would finally get a nap. Right away within 2 days after I got the ergo and pro-adapt bed I was sleeping better, we raised the head up by only 2 inches or just enough my wife could still sleep on her side or stomach but where I could feel my sinuses were less restricted. Now we both sleep much better. She used to have stiffness in her upper back and occasional back pain. Now it is gone. Well worth the money we spent on it.
We bought the firm mattress and it's breaking in well after a month. It's amazing how I don't wake up during the night trying to get comfortable because it's so comfortable anyway you lay on the bed. We are really happy with our purchase.
This is our second Tempurpedic matress and we totally love it. It supports yet cradles your body at the same time. It stays cool and there was none of that new smell even the first night. Super firm for the first week, then naturally learns your body and it's comfort at its best. You get what you pay for. Yes, it's more expensive than other mattresses, but it is the top of the line.
I've been a fan of Tempurpedic since 2004 and recently purchased my second mattress. I also use their pillows and they are wonderful. I get the best night's sleep and wake up feeling refreshed. The memory foam in this bed is so comforting I usually stay in one position and never move around the bed. PS ~ my yellow lab loves it, too!!
