A 1 by 3 inch piece of gray styrofoam from the back of Toby's RA (just at the top, above his head) has broken off! I realized this when I removed the cover to wash it. Given that I have not found the gray piece of foam floating around in the car and that I know that dang thing was intact 3-4 weeks ago when I last washed it I suspect that Delta broke it when we recently gate checked it (3 weeks ago). If it had broken in my car I would have found the foam piece. I had no idea it was broken since the pad covers it completely. Three questions: Should I stop using the seat ASAP? Will Britax sent a replacement for free? Will Delta take responsibility for breaking the seat (if Britax won't/can't replace the foam)? I have Wizard coming for Toby anyway but I wanted the RA as a second carseat and possibly for #2 due in April. Thanks in advance!
