AK 3+4 PET Felt Workplace Dividers


AK 3 and AK 4 are two functional workplace dividers with distinction in size. Made from PET Felt, the dividers grant privacy and dampen the noises at shared desks. AK 3 and AK 4 come in two variations - standing and hanging. With great acoustic performance and many bespoke options, the dividers offer a universal solution for offices and co-working spaces.

Choose your own

The workplace dividers come in 2 sizes - 160 and 180 cm wide, both available in a hanging and standing format. You can choose from 11 PET Felt colour blends. The hanging AK 3+4 has adjustable cords. For the standing version, you can also customise the feet colour.  

Acoustic properties

Thanks to the sound-dampening properties of PET Felt, AK 3+4 demonstrate great acoustic performance. This effect is enhanced by acoustic filling incorporated into the shell. Learn more about the acoustic properties of PET Felt here

PET Felt Technology

PET Felt is a soft, though strong material with a great acoustic performance. It is both recycled and recyclable. The PET Felt technology allows a number of production steps to be reduced to one smart 3D pressing technique. Learn more about it here.
The AK 3+4 are also easy to disassemble and recycle after long-time use.
