Bridgestone Rear Child Seat Cushion Color: Dark Gray Product Information ・Upper cushion, lower cushion, crotch belt pad ・Material: EVA ・Weight: Approximately 170g ・Water-repellent treatment (not waterproof) This item was originally included with the purchase of a rear child seat. I have two seat cushions, and I would swap them out when they got wet from the rain while my child was using the seat. Also, the bicycle was stored in a covered area, so there is minimal damage. I replaced it about 3 years ago and have stored it indoors after washing. No box No instruction manual There are no noticeable stains or scratches. The upper cushion appears to be slightly sun-faded from use. There is some fuzzing on the areas where the zipper tape was in contact during storage. Please check the images for details before considering a purchase. I plan to package it in a simple manner, folded as shown in image 5, with a single layer of plastic. It is too thick to fit in a post, so it will likely be shipped via Takkyubin (courier service) in a 60-size box.
