Not the best solution
Make loud crinkly noises when you move.  Addressed my husbands need for a firmer support, but he would roll off it to my side the the bed.  We found that an alligator crate foam cover, with the solid side up worked better for both our needs.  He requires firmness, I require softness.  This provided a happy medium for both of us.  The Tempurpedic we purchased was too firm for me.  Wish we would have bought a Sleep Number instead.
