This Queen-size 8-inch Thick Memory Foam Mattress - Firm has a firm feel, making it ideal for those who currently wake up with sleeping pains and need extra support. We makes all of their foam using open cell construction. Their unique manufacturing process makes a softer, doughier foam that will quickly conform to your body weight and position. The open-cell construction also optimizes air flow to keep you cool and comfortable while you sleep. The memory foam will quickly contour to your natural pressure points, giving you proper support that will correctly align your spine and help relieve sleeping pains. The foam will isolate motion transfer between sleeping partners, and you know what a good sleep can do when confronting morning breath. Lucid's memory foam helps create a healthy sleeping environment as it is naturally antimicrobial and resistant to allergens, mold, bacteria and dust mites. Designed in the U.S., imported materials were used to provide the highest level of quality and comfort.
