About us

Studio STOUT is a Dutch product design studio, founded in 2008 by Marc de Graaff and Sander Joosten.
We do what we love most: designing great products that bring value and joy to everyday users.
Seeing people use products you've created is the biggest reward an industrial designer can get. That's why we started STOUT.
We are by choice a compact studio, so you always work directly with us, the founders.
Where it fits the relationship, we engage in long-lasting collaborations, becoming a more strategic development partner over time. Alongside designing products, we identify opportunities and innovations that drive and strengthen the brand in years to come.

Mobility, baby and children's products have been at the heart of our work long before the studio existed. These are categories where every detail matters.
Look, feel, safety, reliability, manufacturability and cost all come together in one challenging puzzle, and we have been solving it for over 25 years.

Consumer and design awards really do matter.
They're proof that a product stands out from the competition in quality, appearance or user-friendliness. Many of our clients have won international design awards or industry innovation awards with designs we created or products we worked on.
To us, the real reward comes later, when people like using it so much that they recommend it to others. That's where distinctive design turns into true value worth protecting. We help you secure that value and support you in arranging technical patents or registered designs that protect your investment. Our clients have benefited from both.
Our experience goes beyond the drawing board, deep into manufacturing itself. We've spent years working alongside production partners, including extensive time spent inside Chinese factories. That gives us a real understanding of what happens once the drawings are finished. 

We bridge the gap, translating between the client's commercial, quality and safety needs and the manufacturer's technical needs. And that's how we get it right for both sides.

We also take on projects in different product categories and industries. It keeps our thinking fresh, and ideas from one industry often find a new use in another.

We work fast, communicate clearly, and solve what needs solving for you. No nine-to-five mentality.
Just ambitious but realistic planning. Whether it's your 1st product, your 50th, or you just need a partner to get started, we're ready.

We are serious about what we do, while having fun doing it. So let's talk.

Services

Every product starts with an idea. Turning that idea into a manufacturable product that people actually want to buy requires creativity as well as structure. Creativity is inherently exploratory, energetic and unpredictable. As designers, we embrace that creative momentum, bring together the strongest ideas and use them to drive the product in commercially relevant directions.

That is why successful product development follows a structured process. Not to restrict creativity, but to give it purpose and direction. The process ensures that every aspect of a successful product receives the attention it needs; from user value and brand identity to engineering, manufacturing and commercial viability.

Each phase has a clear objective. Within these phases, ideas are free to develop, overlap and take surprising new turns. At key moments in the process, we bring these different directions together, identify what has the greatest potential and combine the strongest elements. In this way, we turn an energetic and free-flowing creative process into a focused, coherent and manufacturable product.

Analyse

Before we design anything, we make sure we're solving the right problem. Sometimes what looks like the issue is just a symptom. The real cause lies underneath it. So we question the challenge and dig into the problem presented.

We study your ambitions, your market, your competitors and your users. What problems do users have with existing products? What opportunities and limitations present themselves in a rapidly evolving world?

Together, we check if your needs match what our study brought to light. If needed, we adjust the goals in mutual agreement.

The result of our analysis is a well-defined set of project design criteria, set out in a clear overview of wishes and demands. This overview serves as a compass for every decision that follows during the rest of the development process.

Create

We now get creative and explore different directions. This is where products get their identity and where the true value is created.

We visualise the most promising directions until the right one comes to light. So you can see exactly where we're headed before we move on to the next stage. We go from multiple ideas and various concepts into one final design proposal.

We work out every detail in 3D CAD, turning the concept into one fully engineered product.
We protect what initially made the design worth choosing, and use every opportunity to enhance it further.
We build prototypes as proof of concept, test and refine until we're confident it's ready for the factory floor.
And throughout this phase, we keep verifying everything we do against the compass we set together in step one.

Deliver

Once the engineering is final, and materials and production processes are defined, the CAD data and specifications are transferred to the selected manufacturer.

As this marks a transfer of responsibility, we prefer a face-to-face handover. By explaining the reasoning behind key decisions, we protect the design intent and minimise the risk of delays during production preparation and safety certification.

We remain involved throughout the production preparation process, supporting both client and manufacturer. Together, we review adjustments, optimise production, reduce costs and control quality. From the first pilot to final production, we fine-tune where needed, ensure all requirements and certifications are met, and keep design quality as our compass. Because a great concept on paper should become a great product in the box.

Expertise

Two product categories have been at the heart of our studio from the very start: baby and children’s products (Juvenile) and mobility products. Getting products in these categories right takes more than good design alone. It also requires specialist knowledge and a thorough understanding of production, often involving manufacturers in China. Bringing this design expertise and hands-on production experience together is where we do our best work.

Juvenile

The products around a newborn are selected with more care than almost anything else parents buy.

They have to look right, feel right and perform right, in the nursery, in the living room and in daily use.

In this category, only the best any parent can think of is good enough.

We developed strollers, wagons, high chairs, rockers, bouncers, kiddy boards, baths, booster seats, changing mats, bedside cribs, cots, carrycots, seat units, car seat components etc.
Check out our juvenile portfolio section above.

Mobility

From pushchairs to rollators, we design products that move with people through daily life.

Lightweight, foldable, safe and comfortable, while still being manufacturable at the right cost and the quality modern consumers expect and demand.

Sounds simple? It rarely is.
Getting all of that right is what experience does. It's what we do best.

We developed strollers, wagons, rollators, walkers, personal transporters, wheelchairs, children's ride-ons and tricycles. 
Check out our mobility portfolio section above.

China expertise

For many products, China is the factory of the world.
While some clients specifically select us for our production expertise, all benefit from it once their product reaches the factory floor.
We've spent over 25 years working directly with Chinese manufacturers and development departments; working inside the factories, not just over email.

Whether you're a Western brand looking to produce in China, or a Chinese manufacturer developing products for Western markets, we bridge that gap to make it work smoothly and efficiently for both sides.
