I have used this matress topper for about a month now. It is super soft , the very reason for the 3 star rating only. If you are looking for some firmness for your back, this is not for you. The size is just perfect for my queen bed, and the odor is not bad either. It was gone after a couple of days. I would recommend this product for the people who want to have a very soft mattress but if you want a memory foam that is a little bit firm, this isn't for you.
