Full XL Mattress (54" x 80")
- Best For: Taller single adults, older teenagers, or students. It provides the width of a standard Full/Double mattress but offers 5 extra inches of length, accommodating sleepers over 6 feet tall.
- Difference: The Full XL mattress is the same width as a regular Full (54") but is the same length as a Queen or King (80"), prioritizing length within a modest bedroom footprint.
