Great buy for the money. Was thinking I needed a new mattress. This saved me at least $XXX dollars. Tried this 4.5 inch gel topper and it was perfect. The first few nights I was so comfortable I couldn't get out of bed. I weigh over 200 pounds so I decided on a little thicker topper than most. I'm glad I did. Delivery was quick and it was easy to get it out of package. Just follow the easy instructions. I'm sure you'll love it.
