Frequently Asked Questions
About Twin XL Mattress: Memory Foam, Posturepedic, & More - Sam's Club
How to Choose the Right Twin XL Mattress
Five extra inches in length makes a Twin XL the smarter choice for taller sleepers. Here is what to know before you buy one.
A twin XL mattress measures 38 by 80 inches. It’s the same width as a standard twin, but five inches longer. Twin XL works well for taller teens, college dorm rooms, and single adults who want a compact footprint without sacrificing legroom. At Sam's Club, you’ll find Twin XL mattresses in memory foam, hybrid and innerspring styles across a range of firmness levels.
Who Benefits from a Twin XL
Anyone over about 5'5" is likely to sleep better on a twin XL. It’s the standard size for most dorm beds, so it’s a practical mattress for students heading off to college. It’s also a good pick for a teen's room when floor space is limited and a full or queen is too wide for the layout.
Firmness and Type for a Twin XL
Because a wide range of sleepers use twin XL mattresses, the right firmness level comes down to sleep position and personal preference. Side sleepers benefit from a soft to medium mattress with good pressure relief at the shoulders and hips. Back sleepers and stomach sleepers do better on a medium-firm or firm mattress that supports the lower back and maintains spinal alignment. A hybrid mattress is a breathable, durable choice for active sleepers who tend to run warm at night.
