Boston Barstool with Sunbrella CushionAluminum & Woven Fiber Counter Height Bar Seating The Boston Barstool extends the Sevillano Boston design language into bar height seating with a 41 inch overall height and a 30 inch seat height that fits pub table compositions and outdoor kitchen counters. The same enveloping backrest geometry that defines the Boston Armchair scales to barstool proportions, with the polystrand strap rope weave wrapping the backrest at the matching visual tension.
