The straps are a little fiddly, but over all it's well designed. I would have added some backpack-like pull tabs to adjust the height of the person in the harness. The material the straps are made of is a polyester blend, velveteen-type of fabric, and is on the cheap side. The strap material is, well, I wouldn't go so far as to say "scratchy", but it certainly feels "crispy". It's slightly stiff and sort of crackly; maybe that will go away with a few washings, but I'm not certain. The harness support, springs, and carabiners are all extremely sturdy, good quality, and reassuringly thick. Bear in mind that if the wooden support beam you're screwing your eyebolt into is in any way compromised, using this swing would be a bad idea, but that has nothing to do with the product itself.
With a little trial and error, we were able to get into the swing and arrange the straps so I was comfortably supported. The tension springs kept the swing quiet and prevented the metal on metal squeaks that I've heard are off-putting in other swings. It supported my weight comfortably, and our only caveat is that there isn't a way to adjust the height of the person in the swing once they're in it, or at least we haven't figured it out yet.
This is nowhere near to being discreet. It's big, bulky, and covered with pictures of a scantily/provocatively clad couple using the swing... at least it has a carry handle.
