Mattress Type:


The Back Sense Platinum line is where you start when looking for a mattress genuinely made for adult support. A robust LFK-style spring combined with a stable foam-encasement system provides support and stability while the high-quality foam upholstery in the Grand Prairies Cushion Firm ensures the second firmest bed in the Platinum collection will give you comfort and support for years to come.

A cushion firm in the truest sense of the word, the Grand Prairies Cushion Firm is an excellent choice for stomach sleepers and many side sleepers alike, many of whom will appreciate the cradling effect the durable upholstery layers provide while still not allowing you sag too far into the bed. Side sleepers and someone more sensitive to pressure points may want to look at an option with more cushioning layers on the top, such as the Grand Prairies Plush, Jennings Pillowtop, Mystic Cloud Plush or Pillowtop, Stearns & Foster Oak Terrace Pillowtop or most beds in the Tempur-Pedic collection.


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

  • Open-coil and alternating left/right design is stable throughout
  • Durable, long-lasting design that doesn't take a body impression
  • Stress-relieved wire for durability and consistency
  • Heavy-duty 14.5 gauge wire
