A mattress can start feeling worn out long before every part of it is actually worn out. The comfort materials at the top take a lot of the repeated compression night after night, while the deeper support system may still have plenty of useful life left. That’s a big reason we designed the Duo differently. Replace the comfort layer. Keep the support system. Ever had a mattress lose its comfort before it actually felt “old”? #Mattress #BetterSleep #SleepBetter #MattressShopping #MadeInUSA #EngineeredSleep
