This topper has renewed the comfort level of my mattress.  The loft is perfect and stays in place.  It makes one's mattress feel plush and soft - like sleeping on a cloud.  I've purchased three toppers over the last 10 years and this is my absolute favorite.  The price was fantastic as is the quality.  It puffed up as soon as I took it out of the bag...no waiting.  Thanks Wayfair!
