***BEST SELLER*** The Larimer St Cushion Firm is the very top of the line harder feeling mattress in our lineup. The individually pocketed innerspring unit provides for optimum support, while the independent nature of the coil allows for excellent contouring, and virtually no motion or bounciness. There is just enough cushion to make it slightly softer than a traditional firm mattress, and 100% natural Talalay Latex Foam makes it bit softer yet. Latex Foam is ventilated, so it sleeps cooler. The antimicrobial fibers also 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.
