We have had the need for 3 weeks and we love it. We both can move and the other doesn’t feel them movement. It is also firm which is what we were looking for.
We've been sleeping on a queen GhostBed for a few years. When we decided to move to a King, we didn't even consider another mattress. We love our GhostBed. I have slept on other foam and memory foam mattresses. Some are comfortable, but usually too soft. GhostBed gives me the perfect amount of firmness and softness.
