California King Mattresses

The best memory foam mattresses mostly share features such as multi-layer foam construction, zoned support for pressure relief, and temperature-regulating open-cell foams. They balance softness and structure to align the spine, reduce motion transfer, and enhance breathability.

While latex foam is often praised for its durability, it can pose some serious health risks, especially to those who are allergic to this material. The ideal type of foam for a mattress strikes a balance between health and comfort.

Our mattresses use a number of foams including Hygroflex®, a hybrid comfort foam combining the contouring feel of memory foam with high-resilience support. It’s also engineered for fast response and excellent heat dispersion, so you don’t feel stuck in it or overheated. Its design also redistributes pressure evenly and maintains breathability, making it ideal for healthy, restorative sleep.

When choosing a foam mattress, consider the density, firmness, and breathability of the foam, along with your sleeping position and comfort preferences. Look for non-toxic materials, quality certifications, and layered support that promotes alignment.

Memory foam mattresses are usually anywhere between 15–35cm (6–14 inches) thick. We at Ultimate Beds believe your mattress need not be any thicker than 25cm. Anything deeper is simply wasteful, heavier and more costly.
