Tumble Prevention Cushion Hachi [Material Details] The cushion itself is ultra-lightweight, and the material uses mesh, which feels good against the skin and is breathable. This allows babies to stay comfortable even in the summer when they sweat a lot. The shoulder straps can be adjusted freely, so you can adjust them to fit your growing baby. Only tried on once and is unused. There are a few wrinkles on the rubber part, but there are no stains. BABY DOLL Pooh-san's Character Style The style is reversible. Only tried on once and has been washed. Thank you.
