I was looking for various types of compression bags specially designed for zabuton cushions to store five pairs of thick, heavy zabuton cushions (59 x 63 cm) in the closet, but I was looking for a special zabuton compression bag, but there weren't any that were specifically for zabuton, so I bought this one, even though it wasn't specifically for zabuton, because it said “Storage guide: 3-5 zabuton” on the packaging, but it compressed the zabuton more than I expected, so I'm really satisfied with it. I didn't have any problems with the vacuum cleaner, so it was stress-free. The material is also strong, so even if you put 5 heavy zabuton in it, you won't feel any anxiety about carrying it around. I was able to store five cushions in one bag, so I think I'll use one of them to store futons.
