Frequently Asked Questions about Concrete Furniture

What are the benefits of concrete furniture?

Concrete furniture not only has a very special elegant appearance, it is also:

- long-lasting, because it grows stronger every day
- retains its shape
- odorless
- stable
- always unique
- can be made into almost every imaginable shape and size
- environmentally friendly, as it can be produced without waste and recyclable after use
- suitable for allergy sufferers

Is concrete furniture for indoor use?

Yes absolutely. The times when concrete was used only as outdoor building material or for road construction are long gone. Today, concrete is presentable and not only a trend in living spaces, but also makes an outstanding figure in almost every area of life.

Can all furniture be used outdoors?

Concrete furniture from CO33 is fundamentally versatile. The products that should only be used indoors are the furniture pieces with solid wood inserts. Wood or wood materials take on equilibrium moisture content in the surrounding atmosphere. Depending on the ambient humidity, e.g. in the outside area, wood absorbs or releases water vapor. This causes the wood to swell or shrink.

Which material is CO33 furniture made of?

Our concrete consists of an extremely dense cement stone structure in combination with selected minerals and is free of plastics, fibers and reinforcement. Because of this, the prominent feature of the concrete we use is the durability which is ensured in the long term after reaching its final strength. It has enormous compressive strength, is extremely resistant to bending, heat-resistant and non-flammable. In contrast to furniture made of fiber or textile concrete, our concrete has a high load bearing capacity.

Is concrete furniture fireproof?

All furniture without the use of wood or steel meet the requirements of DIN EN 13501-1 and DIN 4102-1 fire resistance class A1 and are therefore fireproof. They are made of pure concrete that is not flammable.

Is concrete furniture heavy?

Concrete furniture from CO33 is produced without additives such as fibers or reinforcement.
During the manufacturing of our indoor furniture, we ensure that the furniture can be transported and set up using man power. In order to make the transport easier, we supply a small dolly with the higher weight concrete furniture.

For outdoor furniture, we recommend that you work with a garden and landscape builder with planning of the outdoor grounds and the appropriate equipment can be used to set the furniture at the destination.
On special request (for a surcharge) we offer you an installation service (within Germany) for indoor and outdoor areas.

Is concrete seating furniture too cold?

Concrete in its normal form is a block storage medium for heat and cold and adapts itself according to its ambient temperature. Due to their shape, our benches have a reduced degree of these properties. The thickness of the material plays an important role. Thus, the seating furniture in the interior has a comfortable temperature; however at a high heat outdoors, it is pleasantly tempered and also gives off some residual heat in cool evening hours.

Is concrete dirty or rough?

The surface of our concrete is extremely smooth and soft. It is provided with a sealant which protects it against contamination. In this way, you get a highly demanding design object in a refined quality and the highest standards of material, optics and look and feel.

Where can I buy concrete furniture from CO33?

You can buy our concrete furniture here in our Online Shop, at selected dealers (link to dealers), and at our factory. We cordially invite you to visit our showroom in Rudolstadt.

How does the delivery work?

Our products are packed very carefully and delivered in cartons or wooden boxes.
For some of our products, we supply you with a small dolly which allows you to move your furniture comfortably.
As a matter of principle, the delivery is provided "as far as the side of the pavement" of the delivery address you specify. The goods are not being transported or unpacked, assembled or mounted by the forwarding agent - neither in the house nor in the garden. You can order these additional services at a separate cost.
For certain products we can only deliver the goods in a disassembled condition, due to technical reasons with freight and packaging. In this case we pay close attention to a simple assembly capability.

In which countries can the furniture be delivered?

When possible, we deliver to all parts of the world (excluding war zones).

How do I set up the furniture?

Transport your CO33 product to the final destination in the original packaging.
If possible, open the packaging only at the installation site. 
Carry your CO33 concrete furniture product with at least two people. For some of our products, you will receive a small dolly which allows you to move your furniture comfortably. Please pay particular attention when looking for a level surface. Sudden impacts from the exterior could damage your concrete furniture.
Before placing your concrete furniture, please check the load bearing capacity of the floors.
Do not push or force your CO33 concrete furniture but carefully lift it on both sides at the same time.
Do not tilt your concrete furniture over its edges!
Depending on the floor structure, apply felt pads to the product in order to avoid damage to the floor covering.
Make sure you have a level surface.

Can I create my own concrete furniture with my own dimensions?

We will be pleased to make your personal and individual desired product if it is possible to produce.

Which concrete colors are available?

Concrete furniture from CO33 is available in natural concrete grey or anthracite (if feasible).
For some concrete furniture (especially for use in public areas), it is important to choose a varnished or painted surface for better maintenance. We can also do this for you.

Can I get concrete furniture from CO33 in other dimensions?

In our Online Shop, we offer some products in other dimensions. For these you can request different dimensions.

Which wood types are available for the furniture inserts?

We offer various types of wood. Simply share your wishes with us.

How do I clean concrete?

Like all objects with daily use, concrete surfaces require regular care. As with any material, the right treatment is also important for the very sturdy concrete stone – from the beginning. This helps avoid soiling and stains and assures that you can enjoy your concrete product for many years.
We pre-treat all products with “Lithofin Stainstop” prior to delivery and initial use. On request and after consultation with the customer, we also provide the product with a sealant. However, this does not provide further care of your concrete furniture!
For the maintenance of the surfaces, please observe the following recommendations:
Acidic substances (such as vinegar, lemon juice, ketchup, wine, champagne, acidic cleaners, etc.) will attack concrete furniture. Keep these substances away from your furniture!
Never use acidic cleaners to clean your concrete products!
Do not place hot objects (pots or pans) on the concrete surfaces.
Remove any soiling from your products as soon as possible.
Daily care and maintenance for the indoor area: For the cleaning of your concrete surfaces, we recommend using clear lukewarm water, possibly combined with curd or stone soap. Then wipe with a dry cloth. In the case of light stains, you can “soak” the soiling with plenty of water. “Lithofin MN Easy Clean” can also be used.
Basic cleaning for indoors and outdoors: From time to time, you can remove stronger impurities with “Lithofin MN Power-Clean”. A refreshing of the impregnation with “Lithofin Stainstop” is then necessary.
Daily care and maintenance for the outdoor area: For the care and preventive stain protection of all outdoor furniture, we recommend a treatment with “Lithofin ALGEX” 1–2 times a year.
Refreshing the sealant: In order to ensure optimum protection, the impregnation applied at the manufacturing site should be refreshed 1–2 times a year. Before re-impregnation, it is necessary to carry out a basic cleaning in order to remove all soiling. The fully dried surface can then be impregnated with “Lithofin Stainstop”.
All Lithofin products are available in our online shop. Of course, you can also contact us for advice. We will be happy to help you.

Is concrete furniture sensitive to stains?

Like all natural materials, concrete is also a receptive material and is susceptible to all kinds of contamination. If you follow our instructions under the previous section "How do I clean concrete", you will have a long time of untroubled pleasure with your concrete furniture and enjoy the lovely patina that will make your concrete furniture even more beautiful over the years.

What can the concrete surface look like?

Our products are made of natural materials and are made by hand. The natural composition is always "individual pieces". In this type of production, color differences and small pore openings - also in comparison to the illustrations in the shop or catalog - are part of the usual nature of the material. In the case of concrete products, shading can also occur. These may include, among others, by influences such as temperature differences, humidity and concrete post-treatments or by impregnation. Such material properties belong to the typical or agreed upon nature of the products and do not constitute defects.

Do I have a warranty on the furniture?

Certain legal conditions apply. Please read our terms and conditions.

Is concrete furniture suitable for allergy sufferers?

Concrete furniture is easy to clean. No dust adheres to its smooth surface and the concrete does not release gases, toxic or volatile organic compounds in everyday use. Thus, concrete furniture creates a healthy interior climate and is also suitable for allergies or asthma.
