I get the booster seats from Walmart for $20 and I put babies in them starting at 12 months when they enroll. They attach to the regular kitchen chairs. I wouldn't want to invest in real high chairs and can't imagine the amount of room they take up. Yikes

I do the same as Momof4 and leave the boosters on M-F and take them off Friday afternoon and stack them up off to the side. Depending on the week I will drop them in the shower or bath to soak on the weekend and put them back on for Monday morning.
