Beach Cruiser Bike Seat by Grand Star Model GS-916. Brand new never used. Why do I have 2 of these you ask? Those of you familiar with my closet may have seen a pattern of me listing items that were once in my sisters shopping cart. The picture of the bike is her seat and she loves it. She loves it so much she added it to her shopping cart 3 times (I can't make this stuff up). By the time she opened her gigantic box the return window was gone (or so she says, she loves to buy, not return). I have to be careful with offers since these are more than 5 lbs each shipping will be a bit higher (for me, not you). Integrated adjustable backrest Fits on standard seat posts 9" long x 10" wide I believe this is also called a Micargi bike seat, however I am listing from the manufacturers mark on the back. Beach Cruiser Bike Seat in Brown with Back Rest.
