It did add softness to my already hot memory foam bed and does help with cooling.  The above pics reference the damaged item I received but it was replaced by Wayfair.  I don’t get as much of a cooling effect I was hoping for with this topper but it is better than what’s under it.  I have a sleep number bed with 4” of foam cushion that was incredibly hot.  This topper does cool somewhat and still allows me to get accurate readings from my bed’s program.
