Can you use a twin XL mattress on a bunk bed?
Most bunk beds are designed for twin mattresses, so the answer is usually yes— it makes for a great bunk bed mattress size!

Before purchasing, make sure to double-check all bed frame dimensions.
Can I put a twin xl mattress directly on the floor?
We do not recommend keeping a twin mattress on the floor – this may reduce airflow and increase the risk of moisture buildup. Using a foundation, platform, or slatted frame can help preserve the mattress and offer the best hygiene and durability.
