I would not recommend you to try Davinci emily mini crib bigger sized mattress as it will completely tarnish the purpose. The crib comes with a four level mattress support, which gives you ample number of options to ensure that you are at the comfort while lifting the baby without risking the safety of the child. I can fit in anywhere I want. Glider and Ottoman in Espresso and BeigeFinish: DaVinci mattress sold separately for added cushioning. They were large, and I did not have the space for them.
