When I purchased my TEMPUR-ERGO ProSmart Base I honestly was really excited and when it arrived and I tested it out I was astonished by the features it provided. I always thought I had a restful night's sleep on a standard flat base but this adjustable base has really improved not only my sleep quality but when I wake up in the mornings I feel more refreshed! The massage features from 20hz to 40hz put me to sleep in less then 6 minutes of laying down on the bed with it going. I have never fallen asleep so fast with it. And right now I am just using my old mattress with it since I am waiting too get my Temp mattress but oh boy when I do get it. If I feel the way I feel right now? I know when I get a real Tempur-Pedic mattress with it I am going too be in heaven. Thank you Tempur-pedic team for creating such an outstanding piece of equipment for sleep wellness! 10/10
