crib and/or matress (church hill tn)

my grandson who just turned 1 yr and my daughter has just returned home to live with us and have brought next to nothing with them. we have made it work and we will continue to do so but a seperate and safe sleeping area for my grandson is a must. and advise on how-to's, perhaps out of the box ideas or any such items that one may be considering letting go of would be most appreciated.
