Greenfeet’s hemp mattresses are constructed with Bonnell tempered steel innersprings. For support the company makes use of pinewood.

Hemp offers a firmer, more solid sleep surface. It is stronger and more durable than cotton. The material is resistant to bacteria mold and mildews which is why it is better used in humid weather.
