At Birch, our mission is to use natural materials that reduce our environmental impact as much as possible, which is why our high quality, natural mattress is produced with raw materials that are sustainably sourced. Our mattresses may arrive in a box, but they are high quality, responsibly manufactured, and safe for you and the planet. In addition, we stand behind the durability of our hybrid mattresses, which come outfitted with hundreds of individually wrapped innersprings and 25 year warranties, so you can rest easy with Birch.
