Can your mattress affect your posture?
It sure can. If your stooped shoulders are caused because you slept on a poor mattress the last 20 years, stand up straight, shoulders back, sleep on a new Tempur-Pedic mattress.
You'll feel great. Wake up in the morning, no morning-after backache. You'll have great posture. You'll look and feel better.
Buy a new Gallery Furniture Tempur-Pedic mattress. Sleep better tonight. Feel better and look better.
