Bar stools aren’t just furniture — they’re part of your countertop system. Wrong height and people lean on the overhang; wrong footrest design and metal gouges quartz edges.
Measure Before You Buy
Seat height: 10–12 inches between seat and underside of overhang. Standard 36″ island → 24–26″ seat. Bar-height 42″ → 30″ seat.
Overhang minimum: 12″ clear knee space. Jonathan won’t sign off on seating over less than 12″ unsupported stone without corbels.
What Damages Stone at the Island
- Metal footrests contacting counter edge when pushed in
- Dragging stool legs across honed marble
- Swivel bases grinding grit into polished quartz
Our Approach
Look for adjustable 24–28″ range, rubber floor glides, footrest set back from seat edge. Add nylon glide caps ($4) to protect island edges — we’ve saved quartz this way in our kitchen.
