Our Orthopedic Ultra Firm model features superior support and durability. It is built with our best offset innerspring system and has a two-sided design with additional cylinder edge supports in every other perimeter coil. High-quality, stitched cotton padding, premium fiber pads and approximately 1 inch of foam per side create our hardest feel. Handles allow you to flip and turn this mattress. The matching, real-working box spring is 8 inches high and features more wire and an additional wood slat for superior support and shock absorption to help extend the life of the mattress. Full and queen-size split box springs are available

All king and Californiaking sets come with a two-piece split box spring.


100-point scale: The higher the number, the harder the feel.

Comfort refers to the feel of the mattress. Our Regency Sapphire Hybrid is our softest mattress at 3 on the comfort scale, while our Orthopedic Ultra Firm is the hardest at 10. Learn more about comfort.


A good mattress will gently support you, while keeping your spine in the same posture as if you were standing. Good support is an important factor to sleeping well. Learn more about support.


Durability is determined by the quality of the mattress, degree of use, weight of sleepers, and proper care. That's why we manufacture two sided mattresses, enabling our mattresses to stay comfortable for longer. Using the matching box spring can help to increase the durability of your mattress.
