Top Ultra Plush King-Size Mattresses


Our review process

No more trying to get through confusing articles and infographics to try to figure out which ultra plush king-size mattress to get! By reading this guide, you'll have an excellent grasp on what types of mattresses are available on the market, so you can confidently buy a mattress that will ensure comfortable sleep for years to come.

If you're looking for a softer sleeping surface, consider an ultra plush king-size mattress. These mattresses provide additional support to give relief to people with back problems or joint pain. With contouring support, they adjust to your body for optimal comfort. They feature a 14-19 pound indentation load deflection ranking and are ideal for people who sleep on their sides. However, they may be problematic if various sleepers will be using the bed, causing the surface to sag if there is a significant difference in weight. Additionally, ultra plush mattresses usually become softer over time, so you'll have to replace them more often.

These mattresses measure 76" X 80" and are great for master bedrooms. They are built to spaciously accommodate couples, offering extra space for you to spread out. However, they are not suitable for small areas, since they can make the room look somewhat cluttered. On top of that, they are large and heavy, making them hard to move and flip.
