Boston chairs are made of kiln dried solid beech wood. The wooden parts have UV protected and eco-friendly water based paints. They keep the wood resistant against outdoor impacts and still keep the soft touch of wood’s essence. With UV resistant coating applied over the wood, the natural texture does not fade. Additionally, the staining procedure offers the wood multiple color alternatives ranging from light to dark. The high density foaming and upholstery on the body create a comfortable sitting experience.

Spare coverings are available for purchase. All fabrics are cut with CNC machines, so they come out in perfectly correct forms. There are many options for upholstery textiles, such as artificial leather, velvet, woven fabric, linen, genuine leather, bouclé, and nubuck. Upholstery can be done using the customer’s own materials; with approval from 5A production.

The five-way swivel bases are available in three different materials: aluminum, chrominium-plated metal and black polyamide. The wheels are made of black polyamide and caps can be made of polyamide or chromium-plated metal. All of these base types are fitted with a gas-lift mechanism hidden discreetly under the seat that provides tilting movement and seat height command, allowing it to conform to individual body types for optimal comfort, even during more time consuming projects. If desired, the wheels can be removed and fixed feet can be installed instead of wheels. Black polypropylene glides are mounted under the feet which prevents from damaging the floor during dragging.
