Set of Four Model 515 Chairs by TON Furniture

An original set of four Mid-Century dining chairs, model 515, produced in 1959 by TON Furniture in one of the company’s former Thonet factories in what was then Czechoslovakia. The design is widely attributed to the Austrian architect and designer Oswald Haerdtl. Model 515 demonstrates Haerdtl’s mastery of proportion and detail. The silhouette is refined and almost architectural in its clarity, yet softened by the elegant curvature of bent beech wood, a technique inherited from the great Thonet tradition. The gently tapered legs, subtle transitions between elements, and visually lightweight construction give the chairs an understated sophistication that still feels remarkably contemporary today. All four chairs remain in good vintage condition, showing only age-appropriate wear and patina acquired through decades of use. These traces of time contribute to the authenticity and individuality of the set. The original seat interiors and upholstery had deteriorated beyond restoration and were therefore carefully replaced with new foam and fabric chosen to respect the character and spirit of the original design.
