This is a type that is fixed to the car seat headrest with rubber bands. Made in Japan. It has been left unused since purchase. There are wrinkles, but the cushion hasn't deflated at all, so how about taking this opportunity? You can probably use it even when you're relaxing on a regular floor chair, although it can't be fixed. Some places sell it for over 5000 yen at the regular price. I've been using the seat cushion and lumbar support from this manufacturer for a long time, and personally, I think they are worth the price. I will send it via Yu-Packet Plus, so it will be packed in a slightly compressed form. Please be aware of this beforehand. Thank you.
