Are you looking to replace or buy a new ALTO seat liner? This is a free accessory with the ALTO pram but sometimes the seat liner can get lost or needs replacing because of wear and tear. This liner is made from the same durable fabric as the inside of your ALTO stroller seat. Designed to be fully reversible. Place the seat liner in your stroller seat and thread the harness through the corresponding slots on the liner to keep it in place. Thread the toggles on top of the seat liner through the fabric loops on the inside top of the stroller seat to prevent it from sliding down while your little one is in the seat.
