ALL of the new technology beds are no flip. They are extremely heavy especially in a King. I purchased an extra firm from this site, and trust me, you won't need to ever flip it !! In fact, you'll need to purchase a memory foam topper because it is SO firm. I love the fact that I can replace my topper if it wears out, and it never affects the mattress. It does have handles on the side if you want to rotate it, but we have never felt the need to.
