Pads are removable. There are wrinkles and creases throughout the seams (overlapping parts) of the fabric. Strictly speaking, it doesn't seem to be sewn, so I think it might be from the parts that were heat-bonded (I'm a novice, so I don't know). Although unused, please understand the above points before purchasing. Also, please refrain from returns or exchanges, including regarding the size. It will be shipped folded. Thank you.
