The Joie Serina 2in1 Baby Swing 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 swing or sitter. Thanks to the wheels, the entire swing can easily change its location and fits standard European door frames. It operates on batteries (seat unit and swing) or mains power (swing). Batteries are sold separately, while the A/C power adapter is included.
