We have a Phil & Ted's Me Too highchair, bought online about 18 months ago (although I can't for the life of me remember who I bought it from).
DS has used it occasionally, when I've been in the kitchen and attached it to the breakfast bar, and literally once or twice when we've taken it out with us.
The thread on one of the clamps has worn down, and it's now impossible to fully fasten it - essentially making it too dangerous to use and therefore redundant.
As I can't remember which retailer I bought it from, is there anything I can do re contacting Phil & Ted's direct? I can't find any contact details for them that aren't New Zealand! I think it should've lasted longer than this, especially with relatively light wear. Am I kidding myself??
