[five-thousand-loaves-of-bread]

also. figured out (part of*) issue of why lean forward like shrimp in wheelchair despite very leaned back backrest

(* part where wheelchair mechanical issue anyway, imagine there body issue component too but no idea why body do it)

is because dump issue!!!!

[id: simple drawing of 3 wheelchairs. wheelchair 1 has straight back n straight seat & form 90 degree angle. wheelchair 2 have leaned back backrest which make back rest to seat angle more than 90 degree but back of seat is also lower than front of seat (has lots of dump). wheelchair 3 have bigger wheels represent by two circles instead of one, back rest is leaned back n angle more than 90 degree but no dump. end id]

so. standard is chair 1 right. everything straight & perpendicular & 90 degree. this make body sit like shrimp because need use core to make sure body stay up and well

so lean backrest back, make angle more than 90 degrees. then soon after, make dump bigger, so back of seat lower than front of seat. figure 2 exaggerated but something like that. this work because dump make sure gravity -> body actually lean back (i think)

but then got bigger wheels (like. still same 24 rim size, just wheels bigger bc have anti pop technology). erased much of dump. think body don’t naturally tolerate angle??

don’t know how explain. but is dump issue

but already at greatest dump current chair can naturally do. just erased by wheel

so thinking abt other ways to increase dump… or increase difference between front seat height vs back seat higher

maybe put in foam wedge under cushion?? but custom cut expensive

don’t recommend do this if you have other options lol imagine this create more issues but can’t really … get another chair
