Firm 12″ California King Non-Flip Foam Encased Mattress
This mattress’s design is for durability, comfort, and luxurious sleep. It’s an ideal mattress for those looking for extra back support as well. A 6-turn Bonnel innerspring unit and heavy duty compressed cotton upholstery pads bring support and flexible comfort. In addition, a 12″ tight-top and foam encasing provide extra edge support. Hence, this enables you to get close to the edges without sinking. This is a good choice for those who require all the support and luxury of a great mattress.
