My wife has the Tempurpedic Symphony and she tried the Queen size pillow I ordered. Needless to say she loved it. The Symphony is much harder than this.*** IF YOU WANT A THICK PILLOW ORDER THE QUEEN SIZE. IF YOU ORDER THE STANDARD YOU WILL NOT BE HAPPY. MOST PEOPLE SAY "WELL, IT'S ONLY 2 INCHES THICK" read the description before you buy. If I'm not mistaken, the Queen size is around 5 inches thick. I LOVE THIS PILLOW!
