I bought this as a winter futon for a baby, but it was too big for the baby bed. I only opened it, and I haven't used it at all. It's a fluffy futon. There are no stains. It's made in Japan, so I think it can be used with peace of mind. It's very warm, and I think you can get through the winter with it. It's from the manufacturer Baby Shower. I will prepare a new bag.
