Unfortunately, you have to purchase their additional sideboards - and this is how the mounting brackets attach to the headboard - from our research (and attempt), it will not attach to a standard bedframe. Also, mounting brackets are not included for the footboard, neither does it mention anything about attaching the footboard in the manual. It simply shows a picture including the footboard (but doesn't include the mounting brackets). I've tried calling Simplicity (July '09), their number is disconnected. I've tried emailing, their email is no longer working - it got sent back to me. I've tried researching the crib on their website, their website is "under construction" and does not include any information on it right now. Not sure if they're going to be around to assist with this.
