Will we run out of seaweed?
Short answer: No.

Seaweed is one of the fastest growing organisms in the ocean. Some species can grow up to half a metre per day.

It doesn’t need farmland, fresh water or fertiliser. Just the ocean doing its thing.

And when it’s grown and harvested responsibly, it keeps coming back season after season.

Will it replace everything petroleum based? No.
That’s not what we stand for either.

So no. The sea is not about to run out of seaweed.

Which is fortunate, considering we’re trying to turn quite a lot of it into foam.

Who’s actually going to write a whole post about foam if we don’t? Exactly.

We know. Foam isn’t exactly a hot dinner party topic. But it’s doing a lot more heavy lifting than you’d think.

Take your mattress. Every night, your body releases a surprising amount of heat and sweat (don’t worry, it’s a human thing). The reason it doesn’t turn into a damp archive of old nights is actually down to smart engineering. This is because of «open cells», which are tiny, connected structures that let air move through so moisture can dry out. It’s basically a silent ventilation system.

Then there’s your bike helmet. That foam is literally designed to fail. It’s engineered to crush and be destroyed on impact, taking the hit so your brain doesn’t have to. It’s a one-time hero.

And in your running shoes? On a 10K, the foam is compressed up to 15,000 times. Whether those shoes still feel «alive» or totally flat after a few months is just down to polymer chemistry and how those tiny cells handle being squashed.

Maybe it’s not that boring after all.

Meet Shaun, Agoprene’s Chief Operating Officer!

Shaun is the kind of person every team hopes to have.

He rolls up his sleeves and does whatever needs to be done. No task is too small or too messy. From production and raw material testing to customer meetings and IP, he wears more hats than most. He also brings a strong focus on scientific thinking and Jidoka, helping the team build processes that are both robust and thoughtful.

He has quite literally driven raw material back and forth between Norway and the Netherlands more times than we can count. Just to reduce risk and keep things moving.

Shaun transformed our production process from day one. What started with buckets and cement mixers quickly became a scalable, automated process that changed everything.

But just as important as what he builds is how he shows up. Calm, steady and always there for the people around him. A grounding presence when things get intense.

We are incredibly lucky to have him💚

About a year ago, in The Monocle Forecast, Celine shared our ambition to launch our automated pilot production within 2025.

We did not commit to a specific date, just the intention to open our first line. No pressure, right 😄

That ambition has since turned into reality.

Over the past year, we launched our pilot line and increased production capacity from 200 kg per month to 250 kg per hour (not all at once, don’t worry). At the same time, we continued refining the material, bringing density down from 180 to 70 m³/kg, while keeping it stable.

Along the way, we shared Agoprene at conferences across Europe and the US, and rounded off the year with a memorable sail in San Francisco together with Farvatn and .ocean.solutions.

Everything points towards an even more exciting year ahead, and we look forward to sharing more as we go!

The human history of comfort!

You could say this is a niche topic. But once you start thinking about it, comfort has shaped human life for a very long time. Before foam, mattresses and sofas ever existed, humans were already figuring out how to make life a little softer.

Let’s take it from the beginning:

1. Comfort has always been a material experiment.
Humans have continuously adapted their surroundings using whatever materials were available, from nature, to industry, and now back again.

2. Tens of thousands of years ago, comfort was about survival.
Grass, leaves, animal hides and other plant materials were used as bedding to provide insulation, reduce moisture and protect the body from cold ground and insects.

3. As societies settled, comfort got an upgrade.
Around 3000 BC, elevated beds appeared in ancient civilizations like Egypt to improve hygiene and airflow. Comfort was literally lifted off the ground.

4. For centuries, nature did the job just fine.
Wool, feathers, horsehair and plant fibres were renewable, repairable and surprisingly effective.

5. Comfort became structured.
In the late 19th century, steel springs introduced industrial support and shape, changing how comfort was built from the inside out.

6. Then came the synthetic shift.
In the mid-20th century, petroleum-based polyurethane foams replaced natural materials, enabling mass production and new comfort standards.

7. Today, we’re asking new questions.
What if comfort could be soft and nature-based?
Biomaterials like seaweed are opening new possibilities for softness, support and renewability.

Tønsberg kommunes klimapris for 2025 ble delt ut mandag ettermiddag. Mottakeren, skumgummigründeren Celine Sandberg, var både overrasket og lykkelig.

Say hi to AgoAir!
Our new, lighter foam.

The name kind of gave it away, but yes — we managed to bring the density down to 70 kg/m³. Which, in simple terms, means it feels softer, smoother and lighter than anything we’ve made before.

The video explain it better than we can.
And guess what? You can get it in our webshop starting today.

Our seaweed foam is part of the Beyond Foams exhibition at this year’s London Design Festival, put together by 🌿

It’s all about new ways to make foam without petroleum, and we’re glad to be a small part of it.
If you’re in London, drop by the Aram Gallery before November 1.
