The chair was used about 3 times, and then the child started walking, so they mostly just touched and played with it without sitting in it. The turtle parts, including the music and lights, work without any problems. (Batteries are included, so it's ready to play with.) All other accessories are included. Everything has been disinfected! The seat rotates 360 degrees, and the height can be adjusted in 4 stages to accommodate your child's growth. The musical toy, which plays piano sounds and melodies, features a learning mode that allows children to learn numbers, shapes, and more in three languages: English, French, and Spanish. ●Target Age: 6 months and up (for babies who can sit up unassisted) ●Product Size (approx. cm): 95×95×94 ●Weight: 5,500g ●Materials: Iron, PP, ABS Resin, TPR, POM, PET, Synthetic Rubber, Polyester ●Weight Capacity: 11kg
