For us 24" was too low. I bought 26" high. A little harder to find but worth it. I mocked it up using a stepstool and box. Take the time to determine the right height. There are also some stools that come in 25", 26.5, 27, 27.5, 29". Our height ranges in our house from 5'5" to just over 6'.

Below is the link for Penney's stools. I've been getting their catalogs for years and have a few saved for when we need to buy them. They seem to have a really good selection, different heights / styles / finishes. When my parents needed some we ended up finding a Bistro set at BJ's Wholesale that was more reasonably priced then Penney's. If you do see something you like at Penney's, be sure to google JC Penney coupon code, you should be able to find a decent coupon. Also sign up for their email deals.

I guess it depends on the height of most people in your family. If I was your DH, I would hate the bottom right at my eye level and would definitely want at least 3-4". Actually, I would want them even higher and would store less frequently used items up there that are pretty even if I needed a stool to get them down. I think even double-sided glass cabinets can make a space feel too crowded and blocked off if they hang too low. They are gorgeous but need to be higher and shorter, imho. You have plenty of other cabinets and drawers there that would be convenient places to store the every day stuff.

So I found these stools at Copenhagen and I really like them!! (and the price.) They are very comfy and lightweight. Issue- I'm doing brass accents. I do have SS appliances but faucet, pulls, lighting are all brass. I do like the idea of mixing metals. WDYT? (the legs are chrome.) Perimeter cabinets are white but island (where the stools will be) is gray. I'd love your thoughts. I'm a very insecure decorator!!
