Simplicity Conversion Rail Kit Conversion Rails For Elllis 4-in-1 Crib?

Conversion Rails for Elllis 4-in-1 Crib? - simplicity conversion rail kit

I have a simple manger Ellis and I understood that simplicity is business. Now I have a sofa-bed, but not my lane conversion into a bed-size.

Does anyone know a dealer who still bears the conversion kit Ellis?

Well, each from a different set of rails for conversion to know it will work?

Thank you!
