For autumn and spring. It can also be used on summer nights. Although I am an amateur inspector, I believe there are no snags or stains. I do not have any pets. I am also a non-smoker. I plan to fold it up small and send it. Please purchase after understanding that this is a used item. Personally, I think it's a beautiful item, but there are individual differences, so please check the photos. Thank you very much! ^_^
