Looses air after a while.

shipping was a bit long, but my son loves this for his ORU Kayak

This raised me up a bit in my inflatable kayak which is what I was after.

I have arthritis in my hips and sitting on my hard Sundolphin Bali 10 kayak was painful after just a short while. I tried multiple different kayak pads and seats, but none offered enough padding or versatility of movement. I saw this cushion and decided to give it a try. It's perfect for me and my kayak. I only need to fill it about half full (would not recommend filling too full) and it cushions my bum and hips wonderfully. Also with the arthritis I need to be able to change my position periodically. This cushion allows for a wide variety of positions, but stays in place until you want to move it, then is easy enough for even this 64 year old woman to move. This makes it possible for me to stay out on the lake all day fishing from sun up to sun down in comfort. In fact it's so comfortable, I sometimes anchor in the shallows and take a nap in my kayak if I get tired! This is also very rugged, and even though it's seen some rough handling, there are no leaks.
