Baby jogger city select seat boards.
Price is per seat board not a full set.
Options are:
Back seat board older style which harness clips onto fabric
Back seat board newer style where the harness goes through the board
Bottom seat board which goes under child's bottom (please check you have space to add this as the older ones don't have the fabric slot).
These are to make the seat fabrics more rigid.
Does have a slight bend to it. But still in great condition.
Please look at photos carefully as these make up a BIG part of the description.
