Mattresses are made from various materials, each offering different levels of comfort and support. Common materials include memory foam, which contours to the body, providing pressure relief, and latex, known for its durability and responsiveness. Innerspring mattresses use coils for support, while hybrid mattresses combine foam and coils for a balanced feel. Other materials include gel-infused foam, which helps regulate temperature, and organic cotton or wool, often used in covers for breathability and natural comfort. The choice of materials affects the mattress's firmness, longevity, and overall sleep experience, making it essential to consider personal preferences.
