I was curious if anybody knew of an office type chair that can be lowered down abnormally far so that you're very close to the ground.

Don't know of one, since that would mean it wouldn't extend up very far at all. Which means it would be un-sellable as an office chair for anyone other than a child.
Most office chairs are designed so the height can be adjusted up or down to keep the ride height at a comfortable and ergonomic level. According to HON, who is an industry leader in office chairs, most of their models are available in one of 3 height ranges: ?Standard-16 to 21 inches ?High-19 to 23 inches ?Low-14? to 19 inches It sounds as though, your best bet would be one that falls into the low category. Keep in mind, these numbers are a guide that HON uses and not an industry standard. Hope it helps.
