The Joie Serina 2in1 Baby Bouncer offers various rocking movements and speeds. The seat unit can be rotated 90°, allowing your baby to be rocked either front to back or side to side. Soothing nature sounds or music, vibrations, and a gentle night light create a relaxing atmosphere. The seat unit can also be removed and used as a portable baby bouncer or sitter. Thanks to the wheels, the entire bouncer can be easily moved to different locations and fits standard European door frames. It can be operated with batteries (for the seat unit and bouncer) or via mains power (for the bouncer). Batteries are sold separately, while the A/C power adapter is included.
