【Convenient 2-Way Design】Normally used as a cushion that gently fits your lower back, providing comfortable posture support even during long drives. When needed, it quickly unfolds into a storage box. It securely stores shopping bags, blankets, etc., in the passenger seat or back seat, and folds up for space-saving storage when not in use. This is a convenient item that combines both storage and cushion functions in one. 【Peace of Mind with Anti-Tip Design】Solves the problem of drinks and shopping bags tipping over on curves or sudden braking. This storage box stands firmly on its own, and the internal dividers keep your belongings stable. It's especially ideal for organizing luggage after shopping or during trips, and provides peace of mind even with vibrations while driving. The anti-tip design doesn't distract the driver. 【Folds Up for Space Saving】The foldable structure allows it to be stored as a thin lumbar cushion when not in use, without getting in the way in the car. It's only 7cm thick, making it easy to fit in the passenger seat or back seat, and can be quickly deployed when needed. The smart design doesn't detract from the car's interior and provides both storage capacity and comfort. 【Compatible with Various Vehicles】Features stoppers on the back for easy installation, simply by inserting it into the seat. It can be used in various vehicles such as the Daihatsu Move and Serena (some seats with uneven backs may have a different fit). Usable in both the passenger seat and back seat, it's suitable for driving, shopping, and everyday scenarios. 【Lightweight and Durable Material】The main body is made of lightweight and durable polyester material. It's resistant to abrasion and has a structure that doesn't easily wear out even with long-term use, providing peace of mind with repeated folding. It's a light and sturdy construction perfect for daily use. The practical material is stain-resistant and easy to clean.
