While there are lots of things about improving the cushioning on the Ergo 2 - I’d honestly just prefer a completely mesh bottom like the back. For those times that I’m not swapping between sitting and standing - as a rather large fellow - the heat build up on pretty much any cushioned chair gets to be a little uncomfortable. That said I’m also open to thoughts on other ways to keep the person in the chair cool when having to sit for long periods.
Perforated cushions would be a great compromise here. Kinda like water drainage holes for potted plants?
