This memory foam is OK, just OK. Even though it is exactly like described, I was expecting it to be thicker. It is not much thicker then a me oryfoam topper which I also bought. The topper is 1/3 of the cost of this topper. I could have saved a lot of money and bought two toppers! It is narrower then a twin mattress as well! If you're looking to put this on a twin bedframe it will be about 3" narrower on the sides.
