We have a britax car seat rear facing for bub. Fits well in our car seat. This product payed for itself the day it arrived… captured a large nappy leak that meant I didn’t have to pull the car seat out of the car to remove the fabrics to wash! Just pulled the seat pad off & threw in the washing machine 👍🏼
Would possibly like to see some fasteners for the wings to wrap around or tuck under the seatbelt.
