Hi and welcome to the board! I did a bit of surfing and it looks like all the posts about this product are 7-8 years old, so I'm guessing it's not longer being manufactured. There are a couple of products that you put over your existing ironing boards:

Finally, the company from your youtube link sounded familiar. I'm a big fan of Bloc Loc rulers, and their company is USAUS. Might be just a coincidence, but I would contact them. If it's an old product, and they manufactured it, they might just have some old stock hanging around. You never know!
