The mattress was delievered today along with the bed frame(support),and my daughter is very happy. She had it made up and it's ready for sleeping.
"I thought it would be longer" she said, measuring it with her arms. "It's not much longer than the twin."
Me, "That's okay sweetheart, it's wide and you can sleep from corner to corner."
"Oh well, at least it's bigger than my old twin sized bed I had been sleeping on, and it just fits my room too. Thanks mom and dad."
