These movable and foldable acoustic screens have been designed in order to instantly define a quieter and more personal space on any desktop. They can be conveniently stored against a wall in a flat manner since their side flaps are fully movable. They can be used in a more or less closed manner depending on how protected one wants to be, but can also be set in a zig-zag manner on a table top. They were originally designed to be used on the multifunctional BuzziPicNic table (with two small extra sliders that fit perfectly in its central opening), but they can be used on any table top to define a specific area when needed.
