Great idea & set up!
I'm only 5' tall - so when sewing at my machine I have to raise up my chair in order to be at the 'right height' ...then my feet dangle and I couldn't reach the machine's pedal. I intend to take the caster/wheels off my cabinet one day, but for now I have a similar set up...I put an upside down banana box underneath the cabinet area. Now my pedal is raised up within reach! Works great for me - but I really like the durability of your Ikea find better.
