Looks sturdy and sits comfortably in the case for smooth rolling. For now I know I was curious to find the exact measurements so I'm sharing them, I hope you find it useful (see photo). My main concern was the height when I sat on the base and it was about 0.8465 inches according to the digital readout. I'll update the review when it's up and running to comment on its actual strength and ease of rolling. I think it should be fine based on my first test impressions.
