The Weight of a Twin Mattress

Facts

• The twin mattress is made for one child or adult, despite its name. It's called a "twin" because it is often used in pairs but it is also more appropriately called a "single." Twin mattresses come in two sizes: standard and extra long (or XL). Standard twin dimensions are 38 to 39 inches wide and 75 inches long. The extra long twin has the same width as the standard, but it adds 5 inches to its length (80 inches long). Extra long twin beds are commonly in college dorm rooms to accommodate various student heights but they are also popular for home use.

Innerspring

• The innerspring mattress is a standard mattress type. A twin innerspring mattress averages 20 to 30 pounds, depending on its thickness (Reference 1). Thickness varies depending on mattress padding, stitching and type of springs, such as coil or pocket. An XL twin will weigh in at the higher range of 30 pounds.

Memory Foam

• The memory foam mattress conforms to the sleeper's body type, isolates motion and can relieve joint pain. The dense foam material makes it heavier than an innerspring mattress. The average weight of a memory foam twin mattress is 50 to 60 pounds; An XL twin will weigh in at the higher range of 60 pounds. Tempur-Pedic is a common brand of memory foam mattresses.

Air Chamber

• Not to be confused with a portable, inflatable air mattress, this type provides individual adjustable support via air chambers instead of springs or foam. The air chambers are lighter than foam, but the total working parts weigh almost the same as springs. The average weight of a twin air chamber mattress is the same as innerspring at 20 to 30 pounds but it may be lighter, depending on the innerspring brand. An XL twin weighs in at the higher average of 30 pounds. Sleep Number by Select Comfort is a common brand of air chamber mattresses.

Considerations

• Manufacturer packaging will increase the mattress weight for shipping orders. Consult the store or manufacturer for added weight and shipping costs. In addition, innerspring and memory foam mattresses may increase in weight over time due to dust, mite and skin cell accumulation.
