The problem with the heavy-duty polyester one was that it wasn't slippery at all. It was like a restaurant tablecloth--like polyester broadcloth. You got all balled up in it when you tried to move. Buzz-kill for sure. It did occur to me, however, that--somehow--it might be more comfortable outside. You know, as just a flop-down-and-rest-your-feet kind of hammock. Haven't tried it yet. Hope your results are better!!!
