Fluid - Self-Inflating Pool Float
The only problem with floating around on a pool raft all day is having to blow up the pool raft. The cool new Fluid - Self-Inflating Pool Float inflates automatically when you unfold it and open the valve and deflates just as easily by rolling it back up and re-closing the valve. It's made from open-cell polyurethane foam that expands as air fills the cells and no pump is required. To adjust the firmness level and inflate the headrest, you will still need to blow a few puffs of air into the raft manually, but most of the lung-collapsing work has been done for you automatically.
