This is the LAKIA child seat cushion (seat cushion) designed for comfort and to prevent sore bottoms. Color: Green (yellow-green) I only attached it to a bicycle twice and tried to have my child sit on it, but they didn't like the fluffiness and refused... I've kept it in storage since then. I only installed it twice at the bicycle parking area, so I never actually rode the bike with this cushion. ◯ It looks clean, but it has been handled by someone else. Please consider it to be in the same condition as something sold at a used goods shop. ◯ Please refrain from purchasing if you are sensitive to used items or cannot understand their nature. ※ It is thick, and shipping costs will be incurred. I cannot accommodate requests for significant price reductions. Please note that it will be compressed for shipping. Material: Nylon, Water-repellent finish. Size: Length 560mm x Width 270mm (measured by us)
