Birch belongs to the family Betulaceae, of which we know about 40 different species. Birch wood has a yellow-white or red-white to light brown color and darkens significantly over some time. Birch wood is medium heavy and has good strength properties: it is elastic and tough. Siberian birch, which we use for the production of our bed frames, is exposed to temperatures up to -50 Celsium degrees and large temperature fluctuations, so the wood from this area is much denser and achieves significantly higher strength and resistance to parasites, fungi and molds.
