By Chair
Bonaldo’s By and By Met dining chairs by Bartoli Design share a padded steel frame and a tailored seam down the backrest.
Cold-foamed polyurethane cushions the seat beneath fabric, leather, or eco-leather upholstery. By uses solid-ash legs, while By Met replaces them with metal supports in painted or metallic finishes, giving the same chair two distinct bases.
Every detail, considered.
