If you're a single person and/or are looking to buy a mattress for an individual that is taller, then twin XL mattresses are a great option. They also serve as the perfect solution for students and teenagers that are looking to grow into their mattress down the road. Unlike standard twin/single mattresses twin XL beds are longer by 5 inches. They measure 39 inches (W) X 80 inches (L), which is the same length as both queen and king mattresses. Twin XL can either come with coils or memory foam depending on what features and benefits you are looking for. Not all mattresses are available in twin XL, buy at National Mattress, we made sure that our customers have the best selection of these sizes available from popular brands including Sealy, Serta, Simmons, and Galaxy.
