Memory Foam mattresses help individuals by contouring to the curves of your body, and taking pressure off of your joints. Memory Foam mattresses also reduce pressure points which helps from tossing and turning at night. Memory foam mattresses are also resistant to mold, bacteria, bed bugs, dust mites and many types of allergens. Memory foam mattresses have the unique ability to mold and conform to your body while dispersing your weight evenly throughout the bed. That's why memory foam mattresses are great for achy joints, morning pains and restless sleepers.
