[This review was collected as part of a promotion.] I was super excited to receive this product; my own mattress was on its last legs. This was one of my first experiences with a king-size mattress, and I was pleasantly surprised. There's so much room! You can really stretch out; I was able to fit me, my husband, and my three cats with room to spare. Due to the more square dimensions, it was slightly harder to maneuver than a queen, but once you get the hang of it it's not bad. It was a bit strange at first to switch from a memory foam to an inner spring, but i have to admit that it's more bouncy and it disturbs my husband less when i get up in the middle of the night. It's also more firm than i'm used to, but after a couple months that seems to be a good thing.
