I purchased this in 2022 to use when I looked after my grandchild, but they grew up quickly and I ended up buying a junior seat, so I'm selling this. I used it about 10 times. There are no stains, dirt, or scratches on the seat surface. There are four linear scratches on the underside of the seat, as shown in photo 10. I think it's very clean, but since it has been used about 10 times, please refrain from purchasing if you are sensitive to such things. The color looks duller than it actually is in the photos due to amateur photography, but it is actually a beautiful black color. I have wiped the main body with a non-alcohol disinfectant wipe. Other washable parts have been washed. I will ship it in the original cardboard box. A camouflage-patterned seat to prevent scratches, to be placed between the seat and the child seat, is also included as a bonus. This seat is unused.
