It fits the bed perfectly with no shortages or overhangs. It is very soft and comfortable but not like a too soft mattress.  I bought it because my mattress is wearing out and I was having difficulty sleeping at night. With this mattress topper I am comfortable and wake up refreshed each morning. The delivery was prompt and it was well packed. I chose the 3 inch mattress over the 4 inch and it is perfect. There was no noticable odor even when first opened.
