I own a Tempurpedic Pro-Adapt Medium Hybrid. I purchsed a TEMPUR-Protect Mattress Protector. It ruined the comfort of my mattress. I woke up with terrible shoulder pain after putting it on the bed. It prevents the sleeper from experiencing the comfort layers completely. If you buy the TEMPUR-Protect Mattress Protector, you may as well buy a $500 bed as you won't be able to feel any of the Tempur Material while sleeping. In addition, they offer not returns, refunds, or credits.
