we purchased 2 of these as replacements for some net hammock chairs that only lasted a few months, in one of our luxury vacation rentals.  the quality is great and they are holding up well with high usage by a variety of different-sized people.  They are mounted outside to a beam on our pergola (for liability reasons, we wrapped the chain around the beam as opposed to simply screwing a bold into the beam) They arrived quickly and exceeded my expectations! Highly recommend!
