I have been investigating the fine art of dishing out a wooden chair seat for comfort today, and made discoveries that can be readily condensed into a, imho miraculously easy formula. So here goes:
Your "sitz" bones or ischial tuberosities are prominences of the pelvis that are the hard spots when you sit. They are pretty consistently located in adult humans as it turns out, though you'll have a hard time finding dimensional data if you go looking! I measured approximate spacing among a slightly inebriated and jovial crowd who endured the indignity with humor and made a rough prototype seat to check my theory. Drill two 2-inch diameter holes spaced five inches apart at center (3-inches of material remaining between the holes). For a finished seat, one would shape the edges, but don't even bother for this experiment - just drill the holes in a piece of lumber and sit down on it. shift around for comfort and when your ischial tuberosities align with the holes you will say aaah!
I will be making two holes in a rectangular stool seat at this spacing, centered about three inches from the "back" edge of the stool, and sanding smooth and dishing out the seat a little. I'll try to remember to post a finished picture, but I found this preliminary result too great and dramatic to wait.
Some individuals might be grateful for a third hole at the centerline and about two inches closer to the back edge - where a tailbone-afflicted person does not need hard support and an average person will not miss it. I have not tested this third hole yet, maybe others will report...
I subscribed to !news at . . . well it probably does not matter. I receive the news the moderators are posting there, but also every single boosted comment anyone makes on the news stories as separate inane postings on my mastodon feed(!) That can't be the way to run a railroad! Can comment reposting be disabled by moderators or can it be suppressed by users? Because othewise, the news feed subscription is a poison pill to my fediverse-based feed.
I used https://browse.feddit.de/ to discover a community of interest and they provided this link to subscribe: !electronics@discuss.tchncs.de but when I paste it in the search field for joining a community, nothing happens, or sometimes there is a "not found" message. A growing pain I suppose. I will keep trying . . .
