Brookhaven, MS Mattress Store

As the standard size for college dorm rooms, a twin XL mattress gives students room to stretch out with 38โ€ x 80โ€ dimensions. Since theyโ€™re made with saving space in mind, twin XLโ€™s donโ€™t offer any more width than a conventional twin, but they do give taller sleepers the leg room they need each night.
