I don't remember the exact year, but I believe I bought it when it was most popular. Washing the cover and attaching it was difficult. There are some places where the inner cushion (urethane) tore during removal and reattachment. It doesn't affect its use. I'd like to take pictures with the cover off, but to prevent further damage, please forgive me for listing it with circles on the photos. The location was incorrect. I've marked the photos. It's the seat. There is an instruction manual.
