My husband and I love our Comfort Deluxe Dual 12 mattress by Magniflex! We have each side flipped to different comforts, which was super easy to do, and you cant feel the divide through the mattress cover!Our previous mattress would make you sink into the bed and had a bad smell to it. We also had bad back pain throughout the day and were never comfortable. With our new Magniflex mattress neither of us have back pain anymore and the mattress never let off any bad odors.I have recommended Magniflex to all of our friends and family in the market for a new mattress!
