Dream On Me Aden 4-in-1 Convertible Mini Crib in Grey, Greenguard Gold Certified

where can I get twin bed conversion kit for this crib?

I have a mini crib mattress that is: 38" x 24", will it work with this crib?

What are the outside dimensions of this crib? It seems that 39x23x36 is for the inside of crib and i need to know exactly how much space i need.

What is the maximum weight that the crib can accommodate? I see 25 lbs listed on this page, but almost all other mini cribs accommodate up to 50 lbs
