Where can I find an inflatable lounge, tube, or float that is sturdy...

...enough for the river? I'm going on a float trip next weekend and I was looking around for something besides a raft or inner tube to float on. I once saw in a pool supply catalog some things that were meant to be used on the river. They were extra sturdy and made of very durable material. Everything else that I find is meant for swimming pools or just splashing around. Any ideas?

A cup holder or cooler area would be a tremendous bonus!

Anything?

What you probably saw was fisherman's float tubes:
