Mine has ‘outriggers’ of 31” but I would be quite happy with that one at 26” wide. You would have to try very hard to push that over.
But unless that Kendon has a lot of alloy in the construction, it might not be quite as lightweight as that young lady makes it look (I honestly suspect out of shot assistance in that video). Mine is portable, but certainly requires effort.
If you want genuine portability, you might look at the Solo brand below. I’ve seen these at race meetings and it’s where my search started. But due to the over hang at the front, and the way the it folds backwards to lower (not a scissor lift), it makes it too long overall for my application.
