Fantastic!
My NSV was similar…I am a massage therapist, and my portable (and light weight, so less load bearing capacity) table lists static and working weight limits. I was always right at the weight where if my client was larger (muscular, soft, dense bones, whatever), I got too close for comfort to climb on the table.
Now, after IF becoming a permanent pattern, I don’t often need to worry.
Not to take away from your accomplishment here, but chair manufacturers are usually pretty conservative with their weight limits. I’ve been as high as 320 and I’ve been sitting on a chair with a 275lb weight limit every workday for months and months. You probably would have been fine. :)
