If its a wood stool, just get the legs cut down. Find a handyman or neighbor to do it. NBD.

We originally had swivel stools at our last house but unfortunately they began to disintegrate after less than a year which was a shame as we chose them because they had a bit of a bentwood, slightly Parisian look going on that complemented our art nouveau stuff :( I was wary of buying more swivel ones TBH and wanted upholstered stools with studded details but in the UK it seemed surprisingly difficult - or at least it did in 2014 - to find high quality, antique style stools so we opted for non-swivel pewter look, industrial (backless) ones from Wayfair. The consolation being they have a vaguely Arts & Crafts feel! Currently we're sans island (making do with a dresser base!) so are not using them, but overall we're happy with the lack of swivel!

It looks like marble, but more than likely it is quartzite (similar to marble.) Especially since it is stored outside. Quartz is not good out in the elements. Be careful if you are choosing it for your kitchen. Quartzite and marble will scratch and etch. Unless you are not much of a cook and the kitchen is more ornamental, I would choose quartz or granite.
