While mattresses generally become heavier as you progress from twin to king sizes, the weight of a queen mattress depends more on its material composition and thickness than its width and length. All-foam mattresses are usually the lightest queen size models, weighing in around 60 to 80 pounds. Innersprings with profiles of less than 10 inches also tend to be fairly lightweight. Foam hybrids have middle-of-the-road weights, typically in the range of 90 to 100 pounds for queen sizes. The heaviest mattress types are all-latex and latex hybrid models, which usually weigh at least 100 to 120 pounds but sometimes as much as 150 pounds or more. Even at 60 to 80 pounds, a queen size mattress can be fairly heavy and unwieldy for one person. We recommend enlisting a lifting partner whenever you need to rotate or move your mattress.
