SORMAG Queen Soft Mattress Topper, 3 inch

This topper is great. It checks all the boxes. It stays put. It feels soft yet supporting. It feels cool to touch and limits night sweating. I toss and turn much less. No need to replace an aging mattress

So far so good. I got this because my husband and I were having back pain on our mattress. As described 3 inch memory foam mattress topper. I left it out to expand for 48 hours before putting on our bed. Very comfortable and although we have only slept on it for a week, neither of us have had back pain in the mornings since sleeping on it. As for cooling I cant say if it has helped or not - I just have not noticed a difference there with it. Has no smell to it out of the box. I would recommend and buy again if needed.
