SHRINX easy chair by Boris Berlin Design for +HALLE, 2025
- realised with custom made SHRINX 4903

In 2023, we presented our vision at Interzum in Cologne: FOAMLESS soft seating—sustainable upholstery solutions without foam, based on our patented SHRINX technology.

Now this idea is really gaining momentum: The SHRINX lounge chair by Boris Berlin Design for +Halle pushes the boundaries of what’s possible:
a lightweight club chair that offers an alternative to the use of foam in soft seating.
The SHRINX easy chair is both a statement and a step into a new category of the future of upholstered furniture.

“We’ve already seen SHRINX fabric as a sustainable alternative to foam in the office chair category, where you typically stretch it over a small backrest and seat,” said Martin Halle, CEO of +Halle. “But applying this technology to something as large as an armchair is a game-changer.” Instead of being stretched over the frame, the fabric of the SHRINX armchair is draped around it and then shrunk.

SHRINX challenges conventional upholstered furniture by completely eliminating PU foam.

Its semi-transparent fabric reveals a foam-free construction and embodies a forward-thinking approach to sustainable furniture design.

Designer Boris Berlin drew inspiration from a club chair for the seat’s shape, creating a sense of lightness and transparency that offers a playful contrast to the usual heaviness of armchairs.

The design makes the chair easy to move and transport, says B.Berlin, and its transparency makes it a less bulky choice for seating in public spaces.
