Product Description

Wrapped in Comfort

Designed by Ramón Esteve, the Sia Dining Chair embodies contemporary elegance through soft, enveloping forms and exceptional everyday comfort. Its sculptural silhouette is defined by a fully upholstered wraparound shell and a distinctive floating lumbar cushion that provides both visual lightness and ergonomic support.

Supported by FSC-certified solid oak legs in a warm Natural Oak finish, the chair balances the softness of its upholstery with the warmth and authenticity of natural wood. Slender, gently tapered legs create a refined architectural presence while maintaining an airy, contemporary profile.

Generously cushioned throughout, the Sia Dining Chair is designed to encourage relaxed dining and lasting comfort. Every detail reflects Acerka’s commitment to timeless materials, thoughtful craftsmanship, and enduring contemporary design, making it equally suited for refined residential and hospitality interiors.

Care Instructions
  • Fabric: Keep your fabrics looking their best by addressing messes and spills soon after they occur. Brush off dirt and debris before it becomes embedded in the fabric. The quicker you clean spills, the easier they can be to remove. Blot (don't rub) liquid spills with a clean, dry cloth. For oil-based spills, apply an absorbent such as cornstarch, then remove with a straight edge. Spray on a mild cleaning solution of soap and water or use a multi-purpose fabric cleaner. Rinse the fabric thoroughly to remove all soap residue.
  • Wood: For regular dusting, use a dry cloth. For cleaning or in case of a spill, use a damp cloth and natural soap. Wipe in the direction of the grain. Do not use soap containing detergent or other chemicals. Dry with a soft clean cloth to prevent spotting. Avoid exposure to extreme conditions: Do not place furniture or accessories near heating sources or air-conditionedspaces. When cleaning the surface, always work in the direction of thewood grain. To prevent color differences, do not place furniture or accessories in direct sunlight.
