Over 5,500 Amazon shoppers have given the mattress topper a five-star rating, calling it "comfortable and cool" and a "fast fix for a sagging mattress." One reviewer even wrote: "I purchased this one about three weeks ago and immediately my sore hip pain was gone."

Even picky sleepers have been won over by this mattress topper, with one explaining that they had purchased this topper to make the beds in their cabin more comfortable. They shared that at home, they sleep on a mattress topper that's four times this price, so initially, they didn't imagine this topper would provide much support. However, they were incredibly impressed, saying, "For the first time, I was able to sleep through the night as well as wake up without my whole body aching!" They plan to buy multiples now, too.
