Why this guide has no chart
A height chart would be the most useful page on this site if the source pages supported one, and the most misleading page if they did not, so this guide refuses to invent one. The source FAQ names adjustable, swivel and fixed bar stools as types, but it gives no seat heights, no counter heights and no clearance figures, and a chart built from general knowledge would send buyers toward stools that fail at their own counters. A buyer who finds a height chart elsewhere should treat it as a starting guess, not as a specification for this company's stools, and should confirm every figure against a sample at their own counter.
The absence of a chart is also a useful signal about the catalogue: bar stools here are sold through inquiry, with height settled per order against the buyer's counter, rather than through a standard size list. That approach is slower than picking a size from a chart, but it matches the source material honestly, and it protects buyers from the commonest bar stool regret, which is a row of stools that look right in photographs and feel wrong at the counter they were bought for.
Measuring a counter in five minutes
Measure the counter height from the floor to the top of the counter surface, at several points along its length, since a long counter may vary by a centimetre or more from end to end. Note the highest and the lowest readings, because a stool chosen for the average height may fail at the ends. Measure the depth of the counter overhang too, since a deep overhang lets guests tuck their knees beneath the counter, while a shallow overhang forces them to sit further back, which changes the comfortable seat height.
Measure the floor as well, since a counter on a raised platform, a thick rug or an uneven terrace changes the effective height a stool must meet. Note the floor material, because a stool that rolls well on a hard floor may roll poorly on carpet, and a stool that stands well on tile may rock on a wooden deck. Photograph the counter with a tape measure visible, since a picture with a measurement communicates more to the company than a bare number in an email.
What to tell the company about height
An inquiry about bar stool height should give the counter height readings, the overhang depth, the floor type and the number of stools wanted, since those four facts let the company judge which stool types suit the counter. Adjustable stools deserve a specific question, since an adjustable stool still has a lowest and a highest position, and a buyer must know both before ordering. Swivel stools deserve a spacing question too, since a stool that turns freely needs clearance from its neighbours, and a row of swivel stools set too tightly will collide.
Back style interacts with height as well, since a stool with a back needs clearance behind it when a guest pushes back, while a backless stool tucks fully under a counter. A buyer should name their back preference when asking about height, because a backed stool and a backless stool at the same seat height feel different at the same counter. Footrest height should be named too, since a footrest set too high or too low for the counter will tire guests over an evening.
Testing a sample stool at the counter
A sample stool at the buyer's own counter is worth more than any chart, and the test takes ten minutes: place the stool at the counter, sit on it, rest the feet, reach for a glass, and turn to a neighbour. Check whether the knees clear the counter underside, whether the feet rest naturally, whether the elbows sit comfortably at the counter edge, and whether neighbouring stools leave room to sit and stand. Repeat the test at both ends of a long counter, since a counter that varies in height will expose a stool that only suits its middle.
Test the stool as guests will use it, not as a showroom visitor would: sit for a full drink, stand and sit again, push the stool in and pull it out, and check whether it marks the floor or the counter. If the sample fails any part of that test, say so in the inquiry and ask what adjustment, what different model or what different type would pass, since a failed sample is useful information rather than a wasted exercise. A buyer who tests before ordering in quantity will never regret the ten minutes the test took.
