I was looking for a mattress topper that is not very thick since mattress is already 12 inch height.I am happy selected  this.I was able to place the topper inside the mattress cover .Our Mattress was giving us trouble after years of wear and tear.This topper feels very plush and adapts to your body posture quickly.give it some hours to gain its full size after getting it out of the package.Overall happy with the purchase
