This self-inflating cushion comes in the tiniest of pouches that would make it easy to hook onto a belt or to stick in a pocket so that you have it when you need it. This cushion is more than adequate for a little extra padding on a stadium seat, a wooden church pew, or just about anywhere you need a little extra padding. I picked this up to have the option of extra padding for my back, or my butt, depending on where I need it when I am riding my recumbent tricycle. It will come in handy in dozens of scenarios like that, and it's small enough to take with me should I need the padding elsewhere. As mentioned, this is self inflating, there is a very thin layer of memory foam inside so that when the pad is unfolded and the valve is opened, the foam expands and draws air in through the one-way valve. Once it is fully inflated you can cap off the valve and it will hold air without any leakage. The initial inflation of this cushion will most likely take a considerable amount of time, in fact I left mine to inflate overnight for it to get to its full thickness. It is slower to inflate for the first time than other similar products that I have used, however after the initial inflation, this cushion should inflate much quicker as the foam should more rapidly expand. Packing it up is simply a matter of opening the valve completely, rolling it up to get all the air out, closing the valves and then it can be left rolled up or folded flat or done with as you please. This has been working well and I look forward to much more use out of it in the future.
