Where can I get an infant security strap for a Chicco Mamma 68270
highchair? I bought the chir second hand, and the strap is misssing.

Howdy petrush-ga,

You can purchase the security strap (Chicco calls it a security strap
assembly) for $17.00 directly from Chicco USA.

Give them a call at their toll free number: (877) 424-4226

Their contact hours are (at least) 9:00 AM to 5:00 PM EST, M-F.
 
When the automated message requests an extension number, dial 234.  Go
ahead and leave a message if it requests you to and they will call you
back.  Nice people, too.

If you need any clarification, feel free to ask.
