Pros - They are very comfortable and we sleep better than our last luxury mattress. My spouse stopped walking up with body aches and did not move around all night. I found myself sleeping being able to sleep better and longer. I stopped waking up with back aches. The SmartPro Base is outstanding and makes our sleep longer with zero gravity. My spouse loves the message option. Cons - Having the King Split keep splitting apart during the night. I am constantly putting them together. Where my spouse has found falling into the opening. Took about 2 weeks to get used to the bed. Is there a way to keep the two beds splitting I would give it 5 stars.
