The air that comes up from the base through the mattress is excellent. Plus I love the bed does so many cool things. I get in bed and put my legs up as far as they will go. That feels great after that I put it flat then lumbar all the way up. It feels so good. Then I use the app to play ocean music to go to sleep with. This bed makes going to sleep so wonderful. The app does a lot more things but I haven't used that yet. I love this bed even though it was a lot more money to buy. It's worth every cent I payed. Don't let the price stop you from purchasing it. I love love it .
