THE KITCHEN SINK! This is as good as it gets for an innerspring mattress. The Blake ST Firm is great for back or stomach sleepers. This beautiful bed uses a touch of 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 the 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.
