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.

This Grand Prairies is a cushion firm in the truest sense of the word and is an excellent choice for stomach sleepers and many side sleepers alike, many of whom will appreciate the mild cradling effect the 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, Interlude Plush or Pillowtop, or the Cascade Plush in the ultra-durable TheraLuxe HD line of bedding.


The Therapedic Back Sense Platinum utilizes the Lura-Flex spring unit from Leggett & Platt:

  • 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

Twin (38"x74").........462
Full (54"x75")..........660
