Our firm mattresses are designed specifically for back and stomach sleepers. The firm mattress options we offer are built with a variety of materials including: a supportive foam core, a durable offset coil, or a sturdy bonnell innerspring. These mattresses provide excellent spinal alignment throughout the entirety of the night. These mattresses will contain just the right amount of comfort layers so you are not sleeping directly on the springs but still get that firm supportive feel desired. The comfort layers in these mattresses are made with the highest quality materials: Talalay and natural latex, high density foams, and cool sleep memory foams that sleep 8x cooler than that of other memory foams. If you sleep solely on your back or stomach one of these may be the right fit for you.
