We are having the best nights sleep in many years. Even though we purchased the "soft", there is plenty of support and firmness for our tastes. I believe the combination of the mattress and the Ergo Plus base attributes to this. Adjusting the base to the "zero gravity" position allows us to sleep on our backs for the first time in years. We are waking up more refreshed and well rested, even if we may decide to sleep in a little longer. Once we got over the sticker shock of what mattresses cost these day, we feel it was well the the investment in a great nights sleep.
