This is a multi-cushion that can be used for child seats, baby chairs, strollers, etc. It's fluffy because it's filled with padding, but the surface is cotton, so I think you can use it for a long time until spring. How about it for a spare? Although it is unused, it has been stored for a long time, so I have cleaned it at home once. There is a faint stain on the back of the cushion. Please check the photos. *This item has been stored at home. I have cleaned it at home once, but if you are concerned, please refrain from purchasing. *Please note that it will be sent in a compression bag when shipped.
