After having this topper for a good 3 years now... I will say it is still perfect and used daily! It is a medium to firm topper. Does keep you cool. Also in the winter months, I keep my home at 65 and noticed the topper gets hard when it is cooler in the room. It gets double it's firmness. While sleeping on it for a few it warms up and gets softer, but most folks don't keep their room as cool as I do. So maybe not an issue. I like firm anyway.
The cover was nice. But not worth the big jump in price. You can purchase the topper without the cover for a lot less here....

My MAJOR complaint was the way it was shipped. Great Offer Stock did not add any paper work with the item. They barely had any wrapping on it. It was merely rolled up and placed inside a dirty carton. They used one piece of flimsy tape across the bottom and top. The weight of the item went right through the tape and busted the box on both ends. When UPS delivered it was all the man could do to keep the item in the box. He suggested they do a better job on packaging such a heavy item. And being it busted through the box and was flopping out, it got a bit surface dirty on the bottom. I cleaned it and it came out. They have a small piece of clear stretchy wrap on the topper that did not completely cover the item. Overall I would say the presentation upon receiving it and the way it was shipped was POOR! It was not the UPS that did a poor job, it initially wrapped and packed poorly. I presume because it was shipped free they don't consider packing well. It was shipped quickly. Overall I am happy. It's not a 5 star rating because overall none of it was worth 5 stars.
I sure hope the next set of Mattress and topper I just purchased today will be shipped nicer than this one was. Hoping they will be in their proper boxes with instructions and NOT dirty like this came!!
