Essentially there tray is made in 2 pieces and therefore has a seam that bisects it horizontally (I've checked, most highchairs are not made like this - probably for the very reason I complained).
What happens is, food gets stuck in the seam, and regardless of how vigilantly you try to keep it clean, eventually you have this brown, gross, grunge stuck in and under the seam that you cannot get out.
And so I complained. Honestly, not expecting to get anything in return. In fact, not expecting any type of response at all. But I sincerely wanted to let them know that this was a design flaw, and hoped they would take it into account for future products.
Well I got a response about 4 days from sending the feedback. They want to send me a new tray to replace the one I have.
I have to say, I was really impressed. (And not only because I'm getting a shiny, new, un-grungy tray) But when's the last time you received amazing, RESPONSIVE, customer service from a company? Much less a Spanish company (yes, the feedback form I filled out was Spanish). So they forwarded the comment to their Canadian Distributor (Elfe) and that is who has responded back.
So there you go - there are some companies in this big, bad world that actually still care about their customers.
