No matter how big your home theater is, the modular design offers endless flexibility, ease of transport, and no tools are required to set up and assemble even the longest sections.

The seats are made up of sectional elements, so finding the optimal layout will no longer be a problem. Can be combined in any way or number, from traditional cinema rows, straight or curved, with or without armrests. Where will your imagination take you?
