Mattress Comfort Level Comfort Zone 1: Extra Firm These mattresses are the firmest available. Very few mattresses are made this way. If you enjoy the firm, supportive feeling of a hard flat surface, an extra firm mattress would suit you nicely. Comfort Zone 2: Firm Mattresses in this category are firm with just a bit of cushioning. They are a good choice when firm support is your highest priority, but a slight degree of "give" is desired for pressure relief. Comfort Zone 3: Medium When firm mattresses feel too rigid, and soft mattresses don’t feel supportive enough, this level is the perfect compromise. Medium comfort zone is also a good option for couples with preferences at opposite ends of the comfort scale. Comfort Zone 4: Plush These mattresses offer a high degree of cushioning. Mattresses in this category are made with additional layers of plush materials for a softer feel, but have enough firmness underneath to keep your body supported. Comfort Zone 5: Ultra Plush If sinking into softness that envelops your body sounds like your idea of true comfort, your sleeping style may fit mattresses within this comfort zone. These mattresses may be thicker due to the extra padding that is used.
