Senior dog loves to sleep on the topper

This mattress topper changed our sleep for the better. We sleep so much better because of it. Our 75 lb senior dog also is obsessed with it and loves to sleep on it during the day and at night.

Sleeping on a cloud

Bought a new mattress that we like but after 40 years on a waterbed we were looking for more softness. We chose the 3 inch memory foam topper. The next morning we new we made the right choice. Now after several weeks we're very satisfied.

Great sleep

This matress is soft and thick. The pad has made my 12" firm memory foam matress feel much softer. Great sleep the 1st night & on. I was planning to purchase a new matress until I tried this topper. Well worth every cent. I recommend it for sure. It will ease those hip pressure points too.
