Iirc he had a sit/stand chair didn’t he?

I remember videos of him demoing like futuristic chairs including one that moved him around in an upright position.

I think he also progressed to a point where he was able to stand and take a couple heavily assisted steps too, wasn’t he? Like him holding himself on something that looked like olympic-style Men’s Parallel Bars?

Maybe I’m misremembering?

But if I’m right, he worked on two levels, too. Couldn’t say that about his horse.
