https://jsfiddle.net/kitesheet70/ybjcfszm/ Buying a Bed Mattress Double The double mattress, also referred to as full size mattresses, is an ideal choice for teenagers and children who want to save space. These beds are ideal for smaller rooms and also can be used in college dorms or apartments. It's also a great option for couples who enjoy cuddling, but don't have enough space for queen or king-sized beds. Comfort If you are buying a double mattress, it is important to ensure that it fits your frame and offers adequate support. The mattress should be as wide as and as long as your frame to ensure it is snugly fitted without gaps. Your mattress should also contour to your body shape, for better pressure relief and support particularly if you're a side-sleeper or have large build. Before king-sized beds became popular, the full mattress (also called a double) was one of the most popular sizes for mattresses in the US. With a width of 54 inches and 75 inches long, it's the perfect size for couples who need an extra large bed than a twin or twin XL, but aren't ready to invest in a queen or king-size bed. For single sleepers either a double or full mattress is a great choice because it provides ample room to stretch out and stay comfortably. It's also a great size for young professionals who are starting out on their own, or for parents who want to impress their adult children with a new bed for their dorm rooms at college. If you're looking for a larger mattress than the standard double or full, there are also mattresses known as "full XL" which are 5 inches longer. They are ideal for taller individuals who require more space to relax, sleep or work at home. A full or double mattress is readily found in many stores and is available with bedding accessories, such as sheets as well as mattress protectors and pillowcases. However, if you're looking to purchase sheet sets for your new bed, make certain that the sheets are specially made for a full or double mattress. If y
