I ordered the Ikea Franklin stool, but find it quite uncomfortable. I’m returning it, and have just ordered the Alera IL adjustable height stool as recommended earlier in this thread; it was just $67 with free shipping from Amazon.
My back likes a stool much better than standing.
The Alera stool just arrived. It's quite comfortable, and the right height, I think for sitting while working at the MFT.
The HD mobile workbench is a little too tall for this stool at max height. Maybe I'll hang on to the Ikea Franklin a little while longer, see if I like using that at the taller workbench.
