Not sure? Flip the Duo Support first
One side of the Duo Support is slightly softer and the other is slightly firmer, so you can change the feel at home. If you need a bigger change, you get one Comfort Exchange. If you’re still not comfortable after about 30 nights, you can use it any time during the 100-night trial. See our warranty and trial details.
Want a different top later?
Duo Comfort Tops are sold separately in all seven feels (Essential, Memory, Memory Plus, Latex, Latex Plus, Performance and Lift) and in Twin, Twin XL, Full, Queen, King and Cal-King. Each top is held in place by CLINGâ„¢, our patented attachment method, so you can refresh the comfort layer or change the feel and keep your Duo Support. For a deeper look at the two latex options, read Duo Latex vs Duo Latex Plus or Latex vs Memory Foam.
