Lassen is one of our 100% chemical-free, biodegradable wool weaves that will bring cleaner indoor air quality and vibrant new life to any space. Since Lassen is produced without any chemicals like fire retardants, artificial dyes, moth proofing or stain treatments, it will not off-gas and instead, will naturally improve indoor air quality by absorbing odors and toxins like VOCs, trapping dust and inhibiting mold growth. This weave has a low loop pile that is soft and insulating. Six colorways are available to choose from, including soothing neutrals like macadamia and almond and the more rich kola. 

All-natural rug underlays are available with this product for added comfort, safety and peace of mind. For broadloom wall-to-wall installation, our Pure Wool Underlay is the right choice to protect your carpet, cushion your feet and enhance indoor air quality. For custom area rugs, the wool rug pad has a natural rubber and latex layer to help prevent slipping. When you order your custom area rug, you will be asked if you would like to include a rug pad. These wool underlays or rug pads are a green addition to your home: bio-degradable, naturally non-flammable and sustainable. Plus, wool pads will help insulate your home while preventing mold growth.

This wool weave is thoughtfully manufactured here in the USA with pure, chemical-free wool from small sheep farms in the UK that focus on sustainable sheep farming and best industry standards for animal welfare and environmental stewardship. Plus, wool is a renewable fiber source and naturally fire retardant, providing conscious consumers peace of mind. 

Please note: Because this wool is not treated with moth repellents, extra care will be needed to ensure the longevity of this carpet. Guidelines for preventing and treating moth infestations can be found in the care guide under the Care tab.

The Natural Choice — Environmentally Friendly.

Fine quality, all natural wool offers numerous advantages when used in flooring. It has been the standard in floor covering for centuries and represents all the qualities that synthetic fibers try to emulate. We use only the finest wools from around the world, which provide all the benefits that wool has to offer. When you are ready to make an investment in your home, consider the following:



Wool is a biodegradable natural fiber and one of the most environmentally forgiving flooring products.


Wool is a renewable product and therefore has less impact on the environment.


Wool has a longer life cycle than other fibers resulting in a smaller environmental footprint.



Wool is a non-allergenic fiber and does not promote the growth of bacteria and dust mites, or give off harmful emissions.


Wool cleans well and won't soil quickly due to its natural soil resistance, making chemical stain protection treatments unnecessary.


Wool fibers absorb and neutralize polluting gases such as formaldehyde, sulfur dioxide, and nitrous oxides.
