I ordered the bed and based on the specifications listed on the website, I also ordered a Full mattress. Looks like, the specifications listed on Wayfair website (80.4") are incorrect, where as the length is 74". As a result, now I am stuck with a Full XL mattress, which doesn't fit the bed. This bed fits a Full mattress, and not a Full XL. Don't go by the specifications listed on the website, they are incorrect.
