Hello Shelley, Bar stools are often problematic... What's on offer with these types of chair in the design world often leaves much to be desired... I see them ruining a good kitchen over and over again, gaudy colours, ghastly design etc etc..... So.... What about introducing another element texture wise... Concrete is a fabulously versatile material... These chairs and bar stools would be lovely by Lyon Beton.. They are beautiful in design and really comfortable- I sat in them at 100% Design... Think they would look beautiful in your kitchen complimenting the metal elements and bringing an additional aesthetic that will "sit" perfectly!! : ) )Bar Stool..

Have you looked at the Hee Barstool by HAY? very reasonably priced and they come in some great colours.

I've got exactly a 17cm gap between my chairs and kitchen table which I can just about cross my legs at so the gap is fine is to me. Sometimes though visually a stool can look too high. I love LTS's first stool (it's looking good with the bar fitted!) but it looks a tad too high for me personally so it might be good to see a pic of your bar. i may be wrong but think it's going to be hard to find a fixed seat of 70cm. Counter stools versus bar stools come within whatever height ranges and I think 70 probably sits in the middle of those ranges. I've found one stool a bit higher and one a bit lower if they're of any use https://www.atlanticshopping.co.uk/bar-stools/pacino-stool-white.html?utm_source=gbase&utm_medium=se&utm_campaign=gb&LGWCODE=9488;19372;5285&gclid=Cj0KCQjwjtLZBRDLARIsAKT6fXzJSHprROxntwEN9tgd3HHstXnDNUiFpiQBh1pZTWNtT2BvLo__AS4aAgF_EALw_wcB http://www.barstools.co.uk/a-x-bar-stool-white.html

I can't really choose either as I much prefer the brushed metal than the chrome and would choose that - but if the other one is more comfy.... I had some black padded ones like the ones in your images (not quite as nice!) typical gas lift faux leather on a chrome base. Very comfy as lots of padding but the faux leather ones were super cheap - maybe £55 for a pair, haha. The chrome was awful and showed every bit of muck and dust and it rusted constantly. They ideally need sealing over with chrome to protect them. The faux pvc to me (even though I actually work with leather!) worked well as they were always getting grubby (especially when the nephews visited and put their dirty hands all over them, haha) and I had to scrub them down a lot so they endured quite a bit over the years I had them. The leather on the stools I imagine is similar to an upholstery leather so it will possibly look the same and not have that real leather feel to it (like some of the leather industrial style stools you find) and although I would always choose leather over pvc, if the seats are housing children then you might want to perhaps look at the cheaper end to start with to see how they get on with them. My nephews would spin on them, go up and down on them constantly, knock them over (rolls eyes) and needless to say, the gas lift started to fail on some of them.
