Purchased from the official Rakuten website in 2021 and used during pregnancy. During breastfeeding, I only used the sofabed cushion for height adjustment, and the rest was stored at home. The sofabed cushion was very versatile, able to be placed between the knees, and was a great help after my belly grew, combined with the U-shaped pillow. Currently sold on Rakuten for 16,280 yen, and covers are also available for purchase. As stated on the official website, it is resistant to flattening, and fluffiness can be restored by kneading the cotton. The cover was washed 2-3 times during use and was washed again for this listing (using Attack 0, no fabric softener). We have no pets, and the storage location was humidity-controlled. Please feel free to comment if you have any questions.
