Versatility and durability, guaranteed

What is the bed made of?

The bed is made of the highest-quality corrugated cardboard, which contains at least 70% recycled paper and is 100% recyclable. Corrugated cardboard is an environmentally-friendly product made from cellulose and starch (corn/wheat) glue. The paints used for colouring are water-based and non-toxic.

Is it possible to paint the bed?

Yes. For best results, spread acrylic paint evenly as a thin layer with a small foam roller.

How much weight does the bed hold?

If loaded evenly, our bed holds up to 1.000 kg/sqm. This maximum weight is not affected by how much the bed is unfolded.

Do I need a slatted frame for the bed?

No ? you can just put your mattress on top of the bed.

How do I guarantee good air circulation?

Corrugated cardboard is very breathable, and the bed's design ensures that air circulates very effectively. However, to prevent the risk of mould, we recommend maintaining a hand's width gap between walls and the long sides of the bed.

How can I dispose of the bed?

The furniture can be disposed easily, as you would any cardboard at your local recycling site.

Is my mattress suitable for the bed?

All mattresses thicker than 15cm are suitable for the bed. If you need a new mattress, you can buy one here.

Can I combine two single mattresses on the double bed?

Yes. In this case we recommend a rubberised mattress protector between the bed and the mattresses to prevent them drifting.

Will the bed slide on the floor?

Although it's extremely rare, some very smooth hard floors may cause the bed to slide. If this occurs we recommend buying an anti-slip mat.

How durable is the bed?

The bed has been rigorously tested to be unfolded thousands of times, and to last as long as a conventional bed.
