The TUBA chair by renowned duo Vrtiška & Žák combines functionality, comfort, and elegant design. Solid yet refined, with precise craftsmanship and an ergonomically shaped upholstered seat for long-lasting comfort.
Our furniture is made from premium European oak, chosen for its strength, beauty, and durability. Each piece is hand-selected and crafted in-house for lasting quality.
Fenno
Wonderfully plush, Fenno is a warm, soft fabric with an almost fleece-like texture.
Woolland
Woolland combines beauty, comfort, and performance.
Wood surfaces: Use a dry or slightly damp soft cotton cloth; avoid microfiber, which can damage oiled wood. Clean spills immediately. Use our Care package to maintain the finish and dry the surface after treatment.
Vacuum upholstered parts regularly and clean with a gentle fabric cleaner. Treat stains promptly without rubbing.
Our chairs and benches (except for the KA series) come with two types of glides, allowing you to easily adapt them to your needs.

The glides for hard floors are already mounted on the product, so you can immediately start using the chairs or benches without worrying about scratching wooden or laminate surfaces. Additionally, the package includes glides for soft floor coverings, such as carpets.
Changing the glides is simple: lift the edge of the glide with a flat screwdriver or the dull side of a table knife, and snap on the new glide based on your floor type.
The TUBA chair therefore represents the perfect blend of design innovation, practicality and aesthetic value that can enliven any space and offer comfortable seating in style.
Vrtiška & Žák
Roman Vrtiška & Vladimír Žák graduated together from the Academy of Fine Arts in Prague and became part of a new generation of Czech designers with a broad creative scope. Their work spans architecture, product design, and graphic design. Among their many projects, they designed the HRIB tables, which contributed to a nomination for the Czech Grand Design Award in 2018.
Their portfolio also includes a variety of designs, from the VETVA shelves and the timeless LUNA clock to the challenging task of creating their own chairs.
All of our pieces are sealed with a linseed-oil & natural-wax blend (oil-wax).

Optional oil-wax finishes (surcharge):
Not every shade appears in the online configurator. If you would like any finish that is not listed there, just send us a quick, non-binding request.
Note: Oak naturally takes on a deeper tone over time due to UV light and oxidation. A light re-oiling every few years refreshes the colour and maintains protection.

For larger orders and complex interior projects, we can manufacture custom products at the customer’s request.
Please consult our expert representatives to discuss your individual needs and possible solutions.
In most cases we rely on our proven standard range. Any custom design is subject to a feasibility assessment. Our broad expertise has enabled us to deliver complete interior fit-outs for both residential and commercial spaces in recent years.
Products such as chests of drawers, chairs, and TV cabinets are delivered assembled. Beds, tables, and coffee tables are delivered unassembled. However, their assembly is very simple - usually only four screws are needed (see installation). The products are packed in five-layer paper carton with special corner protection.
We are happy to arrange assembly and installation for you with our own professional team, who will take care of delivery, carrying, assembly, and of course cleaning up all the packaging and so on.
Details can be found on the Transport, delivery and installation page.

3D models are available to architects and interior designers upon login via our BEOAK PRO platform. You’ll find the model files directly on each product page.
SketchUp does not support FBX files by default. There are two main options to work with FBX models:
1. Using a plugin
The easiest solution is to use an importer plugin like Simlab FBX Importer, Skimp, or Transmutr. For example, after installing Simlab FBX Importer from the Extension Warehouse, you can go to Extensions → Simlab FBX Importer → Import and choose your FBX file.
2. Converting the model
If you prefer not to use a plugin, you can convert the FBX file to a SketchUp-supported format like GLB or OBJ. Several online converters allow you to do this — simply upload your FBX file, wait for the conversion, and download the result.
You can then import the converted file into SketchUp. Textures are usually preserved, and the model scale should be correct. If the model appears too large, it may have been converted using millimeters as base units — in that case, scale it down by a factor of 1000.
