Used in a Koconel Air, this is a baby mini futon set, ★an 8-piece set used in obstetrics and gynecology clinics★. I'm selling this because I bought a different bed for my child and no longer need this set. It's still in good condition, so I'm listing it before I get rid of it! Perfect for the Aprica Koconel Air. It has a firm mattress for stability! Made with antibacterial and antiviral "Clenze" for peace of mind. Antibacterial properties last even after washing. The comforter is lightweight, and the filling is Teijin material that maintains its fluffiness even after washing. It has a cute and gentle design suitable for both girls and boys. Made in Japan by Yayoi Co., Ltd. I used it with care, so it's still usable, but there is a small stain on the back of the mattress. I have included detailed images, so please check them all. Apart from the stains on the mattress and pillow (though both are only noticeable if you look closely), there are no particularly noticeable stains, but there is some slight pilling and signs of use. Thank you.
