XP: Arm's Reach Co-Sleeper w/Platform Bed?

SposaBellarina

We have just recieved the co-sleeper, which we planned to use just as a bassinet b/c we are paranoid and we have a platform bed, which is too low to put the side down anyway.  Arm's Reach also makes a Euro Mini designed for platform beds, and we already purchased the Chicco Lullaby PNP.  Should we keep the mini, exchange it for the Euro mini, or just use the PNP? Thanks, ladies!
