Material, Technology and Production

The wood for our foldable box

The main material of the FridayBOX is plywood, often also called multiplex – a fantastic material für our foldable boxes that can be made from different types of trees.

But not every type of plywood is working for the FridayBOX: Doch nicht jede Sperrholz-Sorte eignet sich für die FridayBOX: poplar plywood for example is too splintery. That’s why we use either birch or beech plywood. Beech wood is more sedate and pricier but we tried it. For the moment the FridayBOX is available due to material features and pricing made of elegant mostly very light European birch wood. This is a great wood, also concerning the technical features.

Wood & Linseed Oil
A tough duo from nature.

The FridayBOX is treated with linseed oil. Linseed oil is used to protect wood for centuries. It is absorbed deep into the wood and hardenes over time. The wood structure stays ‘open’ but is protected from moisture anyhow. We add a bit of orange oil, that accelerates the drying.

This protection can be reinforced or renewed by anyone if neccessary. Just put a bit of linseed oil and a cotton tissue and add a thin layer of oil to the FridayBOX.

Here is a picture to compare the size of erected wooden boxes and a big box that is folded together to a height of 33 mm.

Fastening of the foldable box

The fastening of our foldable wooden box relies on the flexibility of the wood and the proper incisions and geometries, that enables our mechanism withour further fittings or binders.

Fastening of the stackable foldable FridayBOX - snap into place by pushing and pulling.

On all four upper corners the mechanism can be easily and quickly snapped into place.

Fastening of the stackable foldable FridayBOX - open by pushing the button with the thumb.

Folding the box is equally quick. Once the fastening is unlocked, the sides fold smoothly together – nearly by themselves.

How high is the folded FridayBOX?

Folded together the FridayBOX is like a hint of nothing: the BIG one as well as the SMALL one is only 33 mm thin. By being so slim the FridayBOX can be stacked perfectly and particularly space saving when you don’t need it right know. But who owns the box will realize quickly: basically it is nearly never not in use.

How resilient is the FridayBOX?

Primary laboratory and field tests show that the FridayBOX is a really robust foldable box. The wood is impervious to heat and cold as it gets neither brittle nor rough under those exposure. In addition to that our box can be heavily loaded!

We received the lab report and will share the details with you shortly

Meanwhile there is already a number of FridayBOXes out there in urban and rural wilderness showing our diligent testers and us successfully how robust the box is.

One thing we already know for sure:

The FridayBOX can hold more weight than most of us are able to carry. And sitting on it is more an issue of space as our robust foldable box can support more people than those who can sit on it even when sitting on top of each other.

Where is the FridayBOX manufactured?

Home of the FridayBOX is the Rhineland – between Cologne and Dusseldorf. In the Projekt-Zentrale in Dormagen the FridayBOX was invented and continually developed further. Here Michael and his allies manufactured the first batches until end of 2022.

Since January 2023 the FridayBOX is manufactured at Varius Workshops of Lebenshilfe of Rhein-Kreises-Neuss. Michael worked with the Varius team in Grevenbroich on a daily basis to get the production started. It took some weeks to train the colleagues on how to use the CNC machine and manage the technology and software that comes with it. And also to teach them all the tricks and learning a lot himself.
