Wood

Birch and oak are most commonly used, but cherry and other woods may also feature. Birch and oak are classic Scandinavian woods used in furniture production for many years. They are both relatively hard, but oak is the more durable. For oak furniture, white oak is used, which provides the distinctive even surface. G.A.D strives to use oak from the same area to ensure consistency in surface colour and grain. The birch used is of a special light-coloured grade, so that yellowing with age is minimized.

Grade AA wood is used throughout, which when sawed is numbered to ensure that wood from the same source is used in the same piece of furniture. Thus it is possible to follow the grain pattern in the front of drawers and doors. Solid wood is a natural and living element and behaves differently from man-made
materials. The furniture is designed with built-in solutions to allow for the natural movement of solid wood that comes with changes in the relative humidity.

Stone

Many pieces incorporate Gotland limestone, sourced from the south and north ends of the island. It is quarried straight from the rock and transported to the stonemason’s workshop, where it is cut into slices. These are then coated according to G.A.D's instructions, giving a light-coloured surface. Fossils and minor cavities occur naturally in all limestone. We also use black granite and diabase. As a result of sealer treatment, the limestone is stain-resistant.

Leather, steel, and glass

Many chairs and sofas feature leather or sheepskin upholstery. Gotland sheep have a particular lustre and colouring to their fleeces, with beautiful greyscale tones. At times, these fleeces can be a rare commodity.

Steel and glass is used as well. These hard, shiny materials provide an attractive contrast to the other materials.
