I used this about 5 times when I was alone with my baby. I washed it every time after use and dried it thoroughly in a well-ventilated area, so overall, I think it's in good condition. I had a Richell sitting chair of the same type on top of it, and upon inspection, there was a dent on the surface and a chip on the back. Please check the images. The material is styrofoam, so it looks like there are small holes, but this is from when I purchased it. I didn't see any discoloration. Please check the other overall conditions in the photos. I am a non-professional, so I may have overlooked something. I hope you will purchase it understanding that it is a used item. I have thrown away the outer box, so it will be shipped in simple packaging, wrapped in plastic or a paper bag.
