I bought a mattress recently from Wayfair that was much harder than advertised. I mean it was extremely hard to the point where I wanted to return it because it was advertised as medium. But I figured I would try this mattress topper to see if I could save my sleep cycle. I am so happy that I did because it’s actually extremely comfortable and I am now keeping the mattress and the mattress topper because together it is wonderful. I’ve only had it for a week so far so I do not know about the durability over time, but I am very happy so far with the purchase. And it came so fast it was shipped immediately even during this coronavirus pandemic. Only reason why I’m not giving it five stars is because I don’t know how it’s going to hold up over time.
