The mattress itself is very comfortable. I fell asleep with my daughter in her bed and had a great nights sleep. I figured all twin bed and mattress were standard measurements, but when I placed the mattress on the twin bed, the mattress is too short. This mattress is 74 inches long, I needed 75 inches long, so there is a gap between the end of the bed and the mattress. So make sure to measure your bed before ordering this mattress. It's very comfortable, just too short for my daughter's bed.
