The Sit N Stand Ultra stroller has multiple riding positions, allowing children to sit or stand along the ride, or use an infant car seat in both the front and rear facing seats. The Sit N Stand Ultra stroller can accept one or two infant car seats, (sold separately) all Baby Trend infant car seats, and select models from other brands to create a travel system. Used it a few times to go on the bus but now that I recently purchased a vehicle I no longer use it it's still in good condition (no rips, stains ,tears) thanks for looking
