The sales person talked me into getting the Ergo because with some special that I qualified for it was almost the same price as the lower model base. Also, there was one feature with the Ergo that I was interested in (forgot which one it was). I was not interested in the sleep data/sensor stuff and have used it minimally. If I continue to not use all the features I will disable the wifi. The base though is nice and has improved my sleep. The reason why I give this 3 stars instead of 5 because of the wifi and the stupid light on the base.
