the herman miller mirra has a mesh seat but a front that folds down, relieving pressure on that area. i bought mine new in 2006. the mesh tore and was fixed under warranty around 2010. one of the back supports broke in 2015 but they wouldn't fix it for free so i just zip-tied it and it's fine. herman miller's warranty service ain't what it used to be. the best move is probably to buy a lightly used one at half the price, mirra or aeron.
