We husband and I bought a king sized Tempur Luxe Adapt 5 weeks ago. This bed has changed my life! We noticed the difference after the first night we slept on it. I now have more energy and I feel rested. I used to wake up with neck pain and pain on my left side. On previous mattresses I woke up exhausted most mornings because I tossed and turned trying to get comfortable, my husband was also very restless due to his own pain issues. We also purchased an adjustable base with underbed lighting. This has been a life saver as my husband often gets up in the middle of the night. I would say that investing in this bed was the best decision we've ever made. We were hesitant to purchase because of the cost, but now wish we had purchased the mattress years ago. If you are hesitating - please don't wait, you'll be so glad you bought one.
