We got the Donco Kids Twin Low Loft Bed for our 9 year old daughter and it's perfect!. It shipped very quickly. I think we had the entire set within 7-9 days after ordering it. I'm about 5'6" and the mattress is about level with my hip. My daughter's bedroom is pretty small. This bed set provided her with a ton more storage. She loves it! There's still lots of space available under the bed so she set up a lounge/reading area.
