Childs/toddler/twin size (Albuquerque, Santa fe)

In desperate need of some sort of pop up/foldable/cot or bed alike. My four year old is getting to big to sleep with mom and dad and older twin sisters share a twin bed already. All three share a room as well. So something that can be hidden would be ideal. Willing to travel, willing to pickup. Open to ideas and suggestions as well.
