Comfortable air cushion seat pad. Ideal for enhancing seating comfort. You can inflate this manually by pressing on the square that’s by the “inflate” corner but it does take a long time. I used a small air pump in the “deflate” valve with that valve all the way opened. It has a top cap and a second cap to open it all the way. That just took a couple of seconds. It says to inflate it just 60% and seems like the air is not holding, but when you sit on it, you will see that the air distributes around you. Very comfortable and great for home, office or travel. The price is for one cushion. I have one green and one black available. NWOT
