We bought this second hand and it is still in the same condition when we bought it. It's used but in full working order despite some cosmetic marks as shown in the picture.
The upper body straps have yellowed, think its from the sun but like i said, it does not affect the use.
This swing seat is brilliant and was a life saver in the early weeks. Our boy would take his many naps in this during the day and it smoothly unclips from the stand so you can take baby around the house without disturbing them then simply click it back on.
There are different sound settings and a light. Also the seat vibrates but we never put batteries in for that.
Any questions just let me know.
I'm happy to pop the seat material in the wash if requested although it has been washed regularly and protected with a blanket most times.
