We had. Tempurpedic before we purchased the icomfort blue max1000. We had a problem with the tempurpedic so it was covered by warranty and they replaced it but of course they did not have the original we purchased so we had to pick one that just was not the same. My husband had shoulder and back pain when sleeping on the tempurpedic for over a year. We went and purchased the Serta and we have only had it for 2 nights and he wakes up with no pain . It is amazing. I love this Serta icomfort. And the difference in price is amazing also and the comfort is out of this world. They say it could take 10 days or more to get used to a new mattress. With the Serta that was so not true. 1st night and great sleep and wake up refreshed. I don’t know why we didn’t look here first..
