Searched and tested in stores for 3 months. Found this exact one at Raymour and Flanigan and fell in love with it but it was $1400 there and way out of my price range. I found it here online for $680. I already knew it was THE ONE and ordered it. So many aches and pains are now gone. Back pain has gone away. It is like a suction cup you do not want to get out of it when it's time to get up. Amazing matress, not too firm not too soft. BUY ONE!!
