    Looks NOTHING like the picture. It is so NOT a SIMMONS. Horrible packaging. Gel memory foam..... really? This is not what I was expecting based on the way it was presented on the Overstock website. I had to call and get cover sent separately because they forgot to send it. I still may return it but what a hassle!

    I have spine issues. 48 yrs old and 3 separate surgeries. So for the most part I need a pretty firm mattress which is what my wife and I purchased. While her neck issues went away, from the new mattress, I was sleeping in the spare bedroom. It was just too stiff for me. We added this topper and I've been back, in our room, sleeping nightly as it added just the right amount of cushion for my situation. I'M A FAN!! And my wife still has no neck soreness so it worked for both :)

    Bought this for topping a firm mattress that wasn't too comfortable. Added this and it's much more comfortable. Added contouring to body without losing the support from the mattress
