cool hammock/seat thing!
It's a cool thing, and evidently an original idea. How many times have I swished garbage bags around in the air to open them up without thinking of this idea? The problem I see is, I wonder if they work as well as the video seems to show. For example, I bought a kayak that was supposed to be so stable that you could stand up and fish in it, and they had videos of people doing that. The first time I got in it, it rolled over and dumped me in the lake. Sitting, mind you, not trying to stand up.
If I look closely at the people in the inflatable lounger, they don't look exactly relaxed. They look like they're TRYING to look relaxed, while tensing to avoid rolling over. If someone I might be inclined to trust, like an unbiased member of this forum, were to buy one and report back to us that it's entirely stable and not inclined to roll over, I might buy one too. Otherwise, once bitten, twice shy.
