Discarded fishing nets are widely regarded as the most harmful type of ocean plastic as they can “ghost fish” for years, damaging delicate ecosystems and the marine animals that inhabit them. To combat this problem and build upon our commitment to creating a Net Positive impact on the Earth, Humanscale has expanded its Ocean seating line with Liberty Ocean.

Liberty Ocean is Living Product Certified, meeting the most rigorous sustainable manufacturing criteria to date. This means that Liberty Ocean is climate, water and energy positive. Every time we make these products the planet is better off. With a mission to create a healthier world, we are proud that over 60% of our products are certified net positive.

Made from reclaimed fishing nets, the most harmful kind of ocean plastic, each Liberty Ocean sold is one step closer to cleaner oceans.

Back Mesh:



Silver Check

This brilliant weave of monofilament strands and silver-coated yarns offers resiliency and
durability. The award-winning mesh textile was designed to provide optimal ergonomic
support and comfort by melding strength and flexibility. Like Humanscale's other meshes,
Silver Check has a low abrasion factor and is extremely gentle on clothing.

Content: 74% Polyester, 26% Nylon


Monofilament Stripe

This award-winning mesh textile was designed to provide optimal ergonomic support and comfort by melding strength, flexibility and resiliency. Using only monofilament yarns that are thin and strong, a simple but classic stripe pattern is achieved through weave structure and yarn placement. This pattern has slight elasticity, but terrific memory.

Content: 82% Polyester, 18% Nylon



Dash-one of the latest mesh innovations from Elizabeth Whelan Design-was inspired by the way in which the color appears and then disappears, creating a colored "dash" across the fabric surface. Dash combines a variety of elements to be as strong, lightweight and responsive as possible. With a distinct pattern and small scale, Dash carries color brilliantly and densely for a beautiful result.

Content: 87% Polyester, 11% Nylon, 2% Acrylic



Pinstripe is a lightweight mesh, that still manages to provide the strength and support of a much heavier mesh, by using two different monofilament stretch yarns to provide firmness and excellent recovery of the fabric. Only the pinstripe yarns take the dye, and the monofilament yarns are grey instead of black, giving a more neutral background to the pattern and allowing light to pass through the fabric.

Content: 82% Polyester, 18% Nylon
