I babysit my grandkids at their house. Their ages are 5, 2, 5 months. At the end of the day I'm worn out. The saggy mattress in the guest room always left my back aching and joints stiff. I had to do something, so I read the reviews at Overstock and purchased this mattress. IT CHANGED MY LIFE!!! The very first night I sank into bed, and didn't even change position until the 3 a.m. bathroom call. This mattress truly is wonderful. At the recommendation of other purchasers, I also got the egg-carton topper. Soooo comfy.
