Extremely comfy. I wish I bought this a year ago. Even though I spent a fortune on my mattress, it just went up 100 notches with this addition. The cost is nothing compared to how great this mattress topper feels. I sink into it and it feels like Im sleeping on a cloud. Highly recommend. I went through 3 toppers until I found this one. I may just buy another one and keep it in my linen closet just in case they stop selling it. Excellent purchase.
