Thanks everyone for your honest opinions. We are moving towards a memory foam. Too many complaints about the sleep number company.......And, If you spring a leak in the air mattress you are dead in the water......
Although I don't have one, I understand that some folks complain about memory foam mattress as they appear not to breathe like a regular mattress and that the complaint is that the bed is tough on folks with night sweats.
But....I do have a memory foam pillow that has little gel cells on its top side to try to keep my big fat head cool, and I love that pillow - won't leave home without it, it moves from my stick house to my Monte!
We had a Sleep Number bed in our rigs for several years, but upgraded to a memory foam mattress from Sealy and wish we had changed sooner. The Sealy brand are good in they sleep much cooler than many of the other memory foam mattresses.
We have the sleep number bed at home and in the camper and find that the ability to change it to our current level of tired and or sore is awesome. It certainly works for us. Highly recommended. We have the deluxe king model with remote for total flexibility.
