question:
At 80" iong, this is an extra long twin, not a standard twin. Consequently I had to take back the sheets I bought, as they were 5" too short. I would have ordered a different model had I known that 80" wasn't standard. It's easier just to replace the sheets and I don't have time to send the bed back.

Negative
