THE KITCHEN SINK! ***BEST SELLER*** This is as good as it gets for an innerspring mattress. The only way to describe the Blake St Super Pillowtop is Yummy. This behemoth uses Plant Based Memory foam and pressure relieving 100% Natural Talalay Latex foam. It uses an advanced Individually pocketed innerspring unit, which provides for optimum support, while surface level micro-coils allow for excellent contouring, and virtually no motion or bounciness. The antimicrobial Pillow Loft fibers provide for a more temperature regulated sleep, and the 360 degree foam encased edge support makes for a stiff seating edge and reduces roll off.
