text:  This is Mike Casper for Sleep Number. A couple of years ago, my wife and I were purchasing a new mattress, and our argument was over how firm the mattress should be. Sleep Number Smart Beds made that decision easy because Sleep Number Smart Beds let you individualize your comfort so you sleep better together. Only Sleep Number Smart Beds let you choose your ideal comfort and support. Your sleep number setting. For instance, my wife likes a firmer mattress, so her sleep number setting is 65. I like it less firm. My sleep number setting is 45.
