This is the best mattress I've ever had. I love the quality of my Posturepedic Spring Tight Top Medium II. The materials are super soft. This mattress has made my sleeping such better. I sleep so comfortable at night. No more tossing and turning. I have such a hard time getting up at times because of how good laying down on this mattress feels. My children cannot get enough of it. I will soon upgrade the mattresses in my children's bedrooms with these. I am extremely happy to have it and definitely recommend it.
