like so many have posted before, the seat fabric in the back does not hold up to the urges of a 3 year old wanting to be close to you via kicking the back of the seat- the cloth easily releases and pushes in and looks horrible. this was actually a much easier job than i thought it would be and does not require the entire seat to be taken out.

  
the panel that has the fabric pops in little retaining clips and if yours is half pushed in anyway the easiest place to start pulling it out is right in the middle halfway from top to bottom. instead of starting on the outside of the panel pull from the already damaged pushed in area and pull straight back.  then work around pulling it out starting at the bottom area, and top part last- the top is the thinnest plastic and needs to be carefully removed so the plastic doesn't bend (i'd assume it'd get warped and discolor a lighter color like plastic does before it breaks if you go too hard) so take your time. pics show where these retaining points are. there are plastic auto trim tools specifically for a job like this but i didn't have any, so i used a plastic prying tool from removing an ipad screen- point is don't use something metal or there's risk of scratching the plastic shell.

  
once off, from the inside it looks like this thing was melted together at the factory... fabric to plastic using some kind of industrial heating press. there's no glue residue i can feel and the attaching surface is this weird ribbed ridge (last pic). i used a fabric glue that's supposed to be high temp resistant (E6000) and put a generous bead into that ribbed valley. used a pen to roll the tightened fabric into that ridge, let cure overnight.

  
to put back in there's an alignment hole in the top center, just pop back in starting up there working your way down to the side bolsters. last little clips are in the bottom center.

  
so no metal tools needed, give your kids a dum-dum or something and tell them no more kicking the chair! ❤️
