Posted this in chat then realised I'd put it in the wrong place, sorry.
Bought these for the DTs as they go straight on normal chairs therefore I can separate them at the table, which should put an end to the fighting every meal time.
However I can't get them to assemble properly! The harness isn't attached to the backrest as it is on all the photos on the box and online, so they could just slide around. Also I've no idea what the knobs supplied loose in the box are meant to do - it looks like there's supposed to be a strip to strengthen the legs but I don't have that?
Am despairing and wishing I'd not bothered with the hassle of getting new highchairs.
Any ideas?
