      What to Consider When Buying the Best King Size Mattress

      When buying a king size mattress, it’s important to know what type of sleeper you are: back, stomach or side. Next, determine your firmness preference. Mattress firmness rates on a scale from one to 10, with one being the softest and 10 being as firm as it gets. If you like a softer mattress, go for a plush or pillow top design. If you prefer firm, memory foam mattress are your best bet. For a middle of the road pick, hybrid mattresses offer the best of both worlds.

      It’s always important to stick to your budget. Luckily, you don’t have to spend a fortune. There are tons of cheap mattresses that offer exceptional value. If you go with an inexpensive pick, consider adding a mattress topper to increase the comfort level and add a layer of protection. Also, invest in a solid mattress protector to extend the lifespan of your king size mattress.

      Types of King Size Mattresses

      • Innerspring mattresses: Innerspring mattresses are the most common type of mattress. They are constructed with a steel coil support system and layers of cushioning material.
      • Memory foam mattresses: Memory foam mattresses are made from supportive foams that contour to your shape. The foam is temperature-sensitive, so it softens and conforms to your body when you lie down, and then returns to its original shape when you get up.
      • Latex mattresses: Latex mattresses are made from natural or synthetic latex foam, which is derived from rubber tree sap. Latex mattresses are known for their durability, comfort and support. They are also hypoallergenic and resistant to dust mites, mold and mildew.
      • Hybrid mattresses: Hybrid mattresses are a combination of two or more types of mattress materials, such as memory foam, latex and innerspring coils. They combine the comfort and support of memory foam with the bounce and responsiveness of innerspring coils.
