Coppell oak products are made from unseasoned English Oak, traditionally known as green oak. The timber used has been air dried to match ambient conditions and is felled only from UK estates under Forestry Commission license. This ensures that the harvesting of these trees does not damage the natural habitat and also avoids the need for imported timber. As a result English green Oak has a carbon footprint of approximately 7% that of imported Teak, thereby minimizing the environmental effects of your garden furniture.

The furniture is constructed using traditional pegged mortis and tennon joints wherever possible. As the moisture content of the wood changes with the seasons, the whole of the joint naturally contracts and expands together to keep the joints tight.
