The matters topper is very comfortable, however, it runs extremely hot. If you are someone who sleeps warm this is not the topper for you. I sleep cold and in fact it was making me sweat at night. I had to change all my bedding to help cool the topper down. I switched over to natural bamboo for sheets and mattress protector which has helped. I sometimes get hot but for the most part I'm comfortable. I was going to return it for the cooling topper but sale rep told me I would have to pay a fee for them to come pick it back up and they did not have the cooling topper in stock. I gave it three stars due to the fact I can't easily exchange the product and I would need to pay for them to pick it up. Plus pay for the difference in the cooling topper.
I have had sciatica for several months and bought the topper to decrease the nightly threshing about to get comfortable. I have had much less difficulty getting to sleep and staying asleep.
Placed this on top of my current mattress that's just too firm. It feels like a new bed! I don't wake up sore anymore, and that alone is enough reason for me to recommend this product.
I got the twin long size for my dorm bed because the resident halls only provide you with a rectangle piece of plastic. This topper gave me some of the best sleep of my life. All you need to know is that I put it on top of a joke of a "mattress" and it became the best mattress I've ever slept on. Now that I have an apartment, I got the full size to put over my uncomfortable mattress and it feels like falling in love all over again.
I already have a high quality friendly ghost of a mattress but wanted to add a little bit of softness and support. Bought this on the recommendation of the Wirecutter, was a little apprehensive because of price, but it is incredibly soft and supportive, like a fancy hotel bed. Completely eliminated waking up with a stiff lower back, super comfortable.
