I am thrilled with my purchase of the 3-inch gel memory form mattress topper! It is the BEST $125 I've spend this year!! I currently have a nice pillow top mattress, but it is about 12 years old. I was having a bit of pain when I would lay on my sides. My next door neighbor had purchased this about 6 months ago and said it was the best investment! So I trusted her and ordered and I have absolutely NO pain when I am laying on my sides. I also love the Water Resistant Cover. It went on easily! Highly, Highly recommend!
