Just recovered and repadded the seat after 10 years of use. My butt no longer has any natural padding (it shifted to my belly), so I changed the seat padding to 4-inch thick foam.
The thing I love about this seat is it puts you at near standing level, it has both a foot and back rest that are adjustable, and it folds flat for transporting in the van. And, obviously, I sit while performing.
PSR-S950, TC Helicon Harmony-M, Digitech VR, Samson Q7, Sennheiser E855, Custom Console, and lots of other silly stuff!
