The Birch mattress is shipped in a cardboard box that can be broken down and recycled through your local recycling collection program. The box is not needed for any potential returns and can be discarded as soon as you have opened and set up your mattress.
The mattress itself is wrapped in two layers of a Low-Density Polyethylene. This material is considered a #4 plastic for recycling purposes and can be recycled at select stores and recycling centers where soft plastics are collected. Unfortunately, most local recycling collection programs will not accept or be able to recycle #4 plastics.
