the ring is inflatable allowing for precision in setting your desired seat height using an easy grip valve that easily opens and seals. The ring is 16 in diameter providing a wide sitting area spreading weight evenly.
Made from soft but durable vinyl, this ring has a very long life and is latex-free.
To use the ring simply pull the tab to open the valve, inflate to the desired height and push the valve in to seal the air. To store the ring, wipe surfaces clean with a soft cloth and warm water, let out all the air, fold the cushion and return it to its carton.
Store in a cool, dry place away from hot surfaces and sharp instruments.
