I've had my WM knockoffs for 3 years, and the mechanism on one isn't working right. They fit my boat pretty good as cockpit cushions. So mostly they lay out flat I do use them at about 90 degrees when in the cockpit, but they wouldn't stand up to supporting me without a bulkhead or something behind it. The stitching is already coming undone, and I keep them stored below decks when not in use. They aren't quite as comfy as the original sport-a-seats, but they're ok for the money. I've never owned the originals, just sat in them at the boat shows, so I can't tell you if they're better or not. I picked mine up when they were on sail for around $40 each.
