Tab.U Stool
The Tab.U and Big Tab.U stools by Bruno Rainaldi for Opinion Ciatti wrap a plywood structure in hand-wrinkled aluminum.
Chrome or mirrored-gold finishes catch light across the irregular surfaces, making each piece distinct. Low and counter-height versions bring the sculptural form to different seating arrangements, with an optional non-slip felt cushion adding a softer top.
Every detail, considered.

The Tab.U Stool wraps a plywood structure in aluminum that is wrinkled by hand.
The folded exterior receives a reflective surface treatment around the cylindrical form. A low version and a taller companion provide separate seating heights, with an optional non-slip felt cushion for the top. The smaller stool can also act as an occasional bedside or living-room surface.
