I have sleep number and love it. Never tried tempur pedic. My cousin has both she uses tempur pedic and her gd has sleep number. She says gd is always climbing in her bed! I like I can change how hard or soft I want it. I have a bad back, fibromyagia and sleep well. I used to have an aired and loved it but baffles kept popping!
Good luck! Let us know what u buy!!
