We have converted to an eco-friendly material for nearly all of our mosaic surfaces. The material we use is equal in strength, but is made from 99% pre-consumer recycled materials with no formaldehyde added (MDF contains formaldehyde and formaldehyde urea). There are a few exceptions like our occasional tables where we use a weather-resistant material that can be used outside without treating, but most others are made from this wonderful new recycled material. You will find a label on each piece when you receive it that notes that it is made from this great material.
While being "green" actually costs quite bit more than regular MDF, we believe in our environmental efforts and gladly absorb the additional costs. Our material meets or exceeds many of the industry's top certifications for recycled, sustainable and renewable products!
