manduca has developed an accessory called Size-It, which reduces the width of Manduca’s seat and makes carrying small babies even easier.

You can use Size-It separately or in combination with the integrated baby insert. Size-It is easy to adjust and it fits comfortably on the inner side of the seat. The part which comes under the baby´s bottom and legs is well-padded. The child is positioned ergonomically in the expert endorsed M-position.
