There are many types of mattresses on the market today, which can feel very different. Choosing a good mattress means figuring out what you personally find most comfortable.
Innerspring mattresses have metal coils inside for a springy, bouncy feel. The coils can be thick and firm, for more support, or thin and compressible.
Memory foam mattresses conform to your body and have much less bounce. Higher density memory foam mattresses provide more support and are more durable. A layer of gel may be added to memory foam to make it cooler. If you like the feel of memory foam but don't want to replace your mattress, you can get a memory foam mattress topper. Latex mattresses and toppers offer the firmness of memory foam with a little more bounce.
Futon mattresses are traditionally made from packed cotton, although today many are filled with wool, foam and other materials, and some even have coils. A futon mattress on a firm base will usually offer good support.
Air mattresses, or airbeds, are great portable options that can be used for travel, camping or guests. A dual-chamber airbed allows each sleeper to choose their own firmness.
At Walmart, you'll find a wide selection of mattresses at Everyday Low Prices, so you can get the good night's sleep you crave.
