How big is a Twin XL mattress?
Twin XL is typically 38 × 80 inches, 5 inches longer than Twin. Verify the model and frame measurements in the mattress size guide.

How does the comfort exchange work?
Eligible mattresses qualify for one same-size comfort exchange after at least 30 nights and within 120 nights of delivery. There is no exchange fee. Bring the mattress back and pick up the replacement yourself at no charge, or choose pickup and redelivery by our team for $100 total. Pay any increase for a higher-priced replacement; there is no refund of the difference for a lower-priced one. Conditions and exclusions apply. Read the comfort-exchange terms.
Can I try it in a showroom?
