I have recently bought an ANTILOP high chair from Ikea and am generally very pleased with it, compact and easy-to-clean! However the harness that comes with it is really woefully inadequate. While I'd never leave my LO in the chair while I'm out of the room I would like the security of a harness he can't climb out of when I'm at the other side of the kitchen. Has anyone purchased a separate harness and/or can give a recommendation? Thanks.
