Been sleeping on a tempurpedic queen for the last 8-9 years and in general I've been happy with it, although I do tend to get hot very easily (although that's the case with most beds I sleep on).
Looking to get a king and trying to figure out what to look at. Done a ton of work travel the last couple years and have been very happy with the beds at Westin and especially St Regis - the latter is supposedly Beautyrest Black - but read some concerns about longevity.
I'm tall with very long legs and tend to get some lower back pain on beds that are too soft. I also sleep on my side from time to time so tempurpedic has been great for that.
What works for you guys?
