ADJUSTABLE TOILET SEAT ELEVATOR - Inflatable toilet seat cushion provides added comfort when covering hard toilet seats and allows for customizable firmness by adjusting the air volume through the upgraded air nozzle. Close the adjustable nozzle cover after adjustment. Ideal for adults, seniors, elderly individuals, disabled users, and those seeking tailbone pain relief. SAFETY AND EASY TO CLEAN - Made of thickened PVC material, durable and easy to clean. Passed 24-hour leakage testing to ensure reliable performance. LIGHTWEIGHT AND PORTABLE - Weighs only 0.45 lb and supports up to 220 lb (100 kg), making it convenient to carry in a backpack or bag for use at home or on the go. EASY TO INFLATE - Features an upgraded air valve for simple inflation by mouth or with a pump (pump not included). For hygiene reasons, using a pump is recommended. Due to the nature of inflatable products, periodic air refilling may be needed. It is suggested to refill every 3 to 5 days as needed. NOTE: The inflatable cushion includes four suction cups. The two rear suction cups securely attach to most toilet lids and are typically sufficient to keep the cushion in place. The two middle suction cups may adhere fully only to certain parts of specific toilet lid surfaces, depending on shape and material.
