I got this sit and stand stroller from Costco a few years ago. We didn’t end up using it much at all. Can be for the infant car seat or the tray can be attached and turned into another seat. The back part for the older child can be for them to either sit down comfortably or stand .
The infant car seat is also from Costco and is made of good cleanable material. It expires April 10 2022, Holds 4-35 lbs. Price includes both, please text me for info. Child not included.
