Super King Cooling Mattresses

Soft suits side sleepers and lighter frames; medium suits most people and combination sleepers; firm suits back/stomach sleepers and heavier frames. Couples with mixed preferences often pick medium.

A supportive mattress that keeps your spine aligned matters more than firmness alone. Many people with lower-back pain do well on medium-firm rather than ultra-firm; orthopaedic and pocket-sprung mattresses both offer strong support.

Medium-firm gives noticeable cushioning while still supporting the spine. Firm sits closer to the surface with minimal sink, suiting people who want maximum support and minimal contouring.

Medium-firm is the most common compromise. If preferences are very different, dual-firmness or zoned designs can offer balanced support on a single mattress.
