Queen Size Dormeo Mattress Topper. pre-loved for 2 months. perfect condition. Don't need anymore as I replaced with a King size. 60 x 80 x 3 are the measurements. Firmer Octaspring Technology in the middle of the Topper where you need it most. It is made with 3 Zones that adapts to your unique shape to prevent achy hips, back and shoulders. It works wonders no matter your sleeping position. This Topper promotes proper spinal alignment. It makes a huge difference for me with my stiff and achy Rheumatoid Arthritis. I wake up feeling better than I have in a few years!
