Unfortunately, they stopped manufacturing them about 5 years ago. You can still find them on Ebay or Craigslist. They are VERY comfortable. So comfortable in fact, that I've woke myself up snoring a time or two, LOL. But I can hunt all-day, stand up and stretch, and even take a nap without any worry. Another reason I love it, is because I can hunt high (30+ feet), and not be nervous. It's the only stand I've been that confident in.
They have the old videos on YouTube. Here's a link to one:
