ND54 is a children's chair from the brand Carl Hansen & Søn, designed by Nanna and Jørgen Ditzel in 1954. The chair is made of solid beech with a clear lacquered finish and features a luxurious strap in cognac-colored vegetable-tanned leather. Three stainless steel tags for engraving names are included. The children's chair can be chosen with or without a backrest for a baby.

When the couple Nanna and Jørgen Ditzel designed ND54, they used their twin daughters Lulu and Vita, born in 1954, as a reference to determine the proportions of the children's chair. The chair is designed to complement a dining set and is both stylish and elegant.
