The Amalie Counter Stool features a sturdy wood 4 leg base constructed from rubberwood. Rubberwood is a durable hardwood belonging to the maple family. Its dense grain character makes it a stable construction material that is naturally resistant to fungus and bacteria. The polyester upholstery really helps these wood bar stools stand out. The long-term durability of polyester makes it an ideal choice of stool upholstery fabric for families with children and pets. Polyester upholstery is water repellent, stain resistant, budget friendly, and less prone to discoloration.
