Support your child’s feet while using moon in high chair mode. The footrest (sold separately) is easily attached to the seat unit by sliding the white connecting piece onto the bar and clicking into place. Secure with the screw. Next, take the footrest and simply align the two prongs and push until you hear a click. Simultaneously press the buttons on the side to raise and lower the footrest. To remove, simultaneously press the two buttons located on the underside of each prong and pull outwards. Always remove the footrest when using moon in junior mode.
