Husband-and-wife team Renzo Fauciglietti and Graziella Bianchi describe themselves as “designers and researchers,” and they’re known for their ability to combine high-tech function with classic styling. Their Bottega Piston Stool (2003) swivels 360 degrees and instantly adjusts between counter height and bar height – and anything in between – with the press of a lever that operates a gas cylinder. Furthering this luxurious experience, Bottega is wrapped in smooth-as-silk stain-resistant leather that’s hand-sewn onto the slender but strong steel frame to hug every angle and curve. The seat is lightly padded, creating a combination of suppleness and strength that’s not always easy to find. This beloved collection is a top choice for comfortable, elegant seating in any space, from dining room to home office to executive suite and beyond. Made in Italy.
