You need to tuck in well around the tray otherwise baby can pinch the fabric while picking up food. Apart from that, I've barely had to wipe the high chair at all since we've used it. Clean up is so much easier and quicker. Even putting the bib on is easier as the neck and arm holes are stretchy (so much easier than putting arms through sleeves). I definitely recommend this.
I haven't used it yet, but I plan to use it when baby food starts! I'm looking forward to using it because it seems that my son will not get dirty here and there even if he eats while cluttering! The pattern is also cute.
