First decide what height (as in inches) you want/need. The term "counter height" can mean anything though most are 24"

I got a great rush seat set from Amazon cheap. They came assembled. For the price, I am really happy with them. They are actually comfortable.

Got mine from overstock.com just a few months ago. They came fully assembled. We are very pleased, especially for the price. (Even my 83 y/o 4'10" MIL is comfortable on this stool thanks to the footrest!)

Besides overstock and amazon, on line you can find stools at Crate and Barrel, Pottery Barn, Restoration Hardware, All Modern, Design Within Reach... Most furniture stores sell counter stools. have fun!

Got mine from Grandin Road when they were on sale, I have been very pleased with them. I copied somebody here....can't recall who but liked them in the kitchen reveal thread. What style are you looking for? That would narrow it down for folks to make suggestions.

I would like to know the same...I will have a very small bar and will only need one small bar stool for our little Grandson...thanks for your help...
