We had a pair of these stools in our kitchen for a couple of years, and unfortunately most of that time they were wobbly and falling apart! The are pretty attractive though I personally prefer wood instead of 'modern' styles, and the swivel is a bonus (when it's safe to do so!). They are chrome with black leather effect cushions, and I have seen them in red or cream also. Our pair are now quite long in the bin so I can't tell you the height of them (though this is easily found if you are looking to buy them).
What I can tell you is that for me, they were not comfortable at all. The seat is slightly cushioned, but I found my rear got numb quite quickly and the placement of the footrest bar just didn't work for me. I am 5'4" and when I sat on these I felt the footrest was too low; my feet could sit on it but there was no support there, they were practically hanging. This isn't much good for me due to existing hip problems, but even without these issues I would prefer to have a higher footrest so my legs got a proper, supported rest. But I guess someone with longer legs wouldn't be troubled by this! Another thing I wasn't crazy about is the backrests. They are very curved and as a result you can't actually lean on them properly without your shoulders being pushed forward, if that makes sense. So your arms are not in a natural position.
Cleaning them is easy, they can simply be wiped down to remove any dirt. They come up looking great but I found that rust was quick to appear in the nooks and around the cushion, despite me never leaving them wet. Their build quality I'm sorry to say is very poor in my opinion. These were not put to excessive use in my home, but they very quickly became unstable. The fixings attaching the seat to the leg frame fell out which resulted in the seat listing to either side, and though the seat was still attached it lost its swivel. I wouldn't have chanced it anyway! When in use, we were all a bit paranoid about the seat falling completely off, and this results in you literally being on the edge of your seat, which is no good for a rest.
The fixings attaching the footrests also fell out and I actually resorted to using brown parcel tape in an attempt to secure them enough so I could rest my feet on them (being careful not to put my full weight on them mind!) This did work after a fashion, which is rather funny. The problem with the footrest being lose is that the legs start to splay and again, you feel very insecure sitting on them. You can feel the legs moving beneath you as the circular footrest bar acts to support the legs and keep them in place. Not only do the legs splay, but the bottom parts of the legs fall clean off! The legs are composed of two sections of tubular metal, the lower part slotting into the upper part and being held in place by the bolts that go through the footrest, so when these fall out there is nothing to keep the bottom leg sections in place except weight from above.
All of these fixings problems could theoretically be sorted, but we found that even after screwing the bolts back in best we could, the damage was done and the problems just kept recurring after a short time. In any case, it's not really acceptable to me, these things started happening after not that much use. For these reasons I could never recommend these. I think the quality is not worth the price at all; when the first chair went dodgy we planned to buy a new single one, and found them priced between £25 and £30 each. If you have a two sided breakfast bar and wanted 4 of these, then you'd be looking at £100 for stools that don't last.
On the up side, they do have decent non slip feet though!
In the end I bought a pair of traditional style wooden bar stools (uncushioned but comfier, honestly!) for £20 and they are stable as you like, with better back rests and good footrests. And our Bermuda swivel bar chairs unfortunately went to the tip!
