You know that television commercial for Simmons mattresses that show them dropping a bowling ball on the bed to show how wonderfully the independent coil (motion separation) system works? Well – that’s our new bed, and from the jumping tests we did in the showroom (luckily there was no one else around to tell us to act our age – even the salesman was on crutches and in the back room instead – LOL) it’s TRUE! There IS a difference! heh heh. YES!
