I dont think they do. The car seats do because the straps and everything may not be as strong after ao long but with a stroller I dont think it would matter as much since its not used for safety like a car seat.
Yes the car seat expires but i don't think strollers do. My mom has one for the grandkids that she's had for over 20 years.
I mean to strollers have an expire date like a car seat. I was told the car deat expires! Im not sure if im saying it right lol
