We used this standard-sized crib for our two babies. They have outgrown it, and now you can have it. The mattress is Greenguard Gold certified. Mild signs of wear, but everything is in good condition. The height can be adjusted from low (for older babies and toddlers, where it is now), to higher (for infants and newborns, so you can more easily reach them.)
If you're interested, please tell me 2-3 firm time windows when you can come pick it up. And please be sure you have a vehicle that can carry it. (A SUV or station wagon should be fine.) It is currently disassembled, and it's easy to reassemble it.
