The Back Sense Elite line is where you start if you're looking for a mattress genuinely made for adult support. Hickory Springs InnerACT innerspring combined with a robust foam-encasement system provides support and stability. Utilizing quality, high-density polyurethane foam upholstery, the Marengo is the first and firmest bed in the Back Sense collection.

The Marengo Firm is undoubtedly the hardest bed in the Back Sense collection. Utilizing quality, high-density polyurethane foam padding in conjunction with pre-compressed insulator pads to give the Marengo a hard feel, this bed is no slouch.  The support system in the Marengo is also utilized in the Potomac Cushion Firm, Potomac Plush, and the Newcastle Pillowtop.

Great for stomach sleepers and those used to a firm hard bed. Side sleepers may need to look at something with more cushioning on top, or else may need to add their own in the form of a mattress topper.


The Therapedic Back Sense Elite Firm utilizes the InnerACT spring unit from Hickory Springs Manufacturing.
