With QUADRO, you can build a brand-new model every single day – whatever the mood, the moment, or the weather calls for. And as your kids grow and their motor skills develop, you simply adapt the system to match. QUADRO replaces countless other toys with smart expansion kits that integrate seamlessly into your existing setup and are ready to play with in no time. Whether it’s slides, pools, wheels, nets, or fabrics – every element brings fresh possibilities to your QUADRO design.

That means one system covers five core areas of play: building, climbing, riding, sliding, and splashing. Instead of a chaotic toy mess, you get a clear, customizable play world – perfectly tuned to your child’s abilities, talents, and interests. That’s what makes QUADRO a one-of-a-kind construction system for families who love to build, grow, and make memories together.

With QUADROmini, you get a clever design tool to plan out your builds—plus a creative play system for big and small ideas alike. From excavators to spaceships, castles to race cars—whatever you prototype in miniature, you can later bring to life full-scale with QUADRO.

The click system works without screws, making it perfect for experimenting, rethinking, and rebuilding freely. Along the way, kids naturally strengthen their fine motor skills and develop a deeper understanding of structure and space.

Older kids and even adults will discover new potential with QUADROmini: their designs become more precise, more complex—and ready to scale up one-to-one with the full-sized QUADRO system. That’s because QUADROmini is modeled at a precise 1:5 scale.

By coordinating your parts inventory between QUADROmini and QUADRO, you can make even the wildest ideas a reality—small or large.

The QUADRO Model Database gives you access to over 500 unique designs, organized into three categories: Core, Combo, and Mega models.

• Core models can be built using your existing large construction set.
• Combo models require one additional set to complete.
• Mega models combine multiple sets for maximum creative freedom.

Each model includes a 360° view, detailed building instructions, a parts list, and a 3D design file for the QUADRO software. You’ll also find recommended starting age, overall dimensions, and estimated build time.

It’s the perfect source of inspiration for families—browse the designs together, pick your favorite, and plan your next building project with everything you need at a glance.

Plan First. Build Smarter.

Building together is at the heart of the best childhood memories. But sometimes, it’s worth taking a step back and planning things out—like when the kids are asleep or you want to make the most of the parts you already have.

With the free QUADRO 3D Design Software, you can virtually design, refine, and print your models. The built-in parts list helps you use your inventory efficiently—perfect for anyone who values precision and wants to get the most out of every piece.

Even experienced QUADRO fans will love it: Think through your designs step by step, test new ideas, and save your creations for later builds.

Check out the how-to videos for the QUADRO Design Software here.

The heart of QUADRO is the iconic plug-in system — built to give you maximum freedom to create.

With QUADRO, you can transform your design anytime: today it’s a learning tower, tomorrow a play table with a bench, and the next day a pool with a slide — all using the same parts.

Our high-quality materials are inspired by food-grade packaging — built to last, non-toxic, and incredibly durable.

Co-developed with TÜV, the system even meets the tough standards required for use in daycares — tested, safe, and made to withstand rough play.

Many play products – especially wooden ones – are tough to bring back inside after outdoor use. They absorb moisture, dirt, and odors, making clean indoor play nearly impossible.

With QUADRO, that’s never a problem. Our high-density components don’t absorb water or smells. Just rinse them with water and a bit of household cleaner, and your QUADRO is ready to go – indoors or outdoors.

There’s no need to seal, paint, or treat anything. QUADRO stays tough, splinter-free, and easy to clean – all year round.

Simply put: it’s a play system that’s built to last and ready for fun whenever and wherever your kids want to play.

What do we mean when we say QUADRO grows with your child? It’s simple – every QUADRO product is fully compatible.

Start small – maybe with a set perfect for a one-year-old. As your child grows, just add more parts or new features. Everything fits together. Everything works seamlessly.

Unlike many toys that get boring fast or are quickly outgrown, your QUADRO model can always be updated – just like your child’s motor skills and abilities keep growing.

That means play stays exciting, the system lasts for years, and you avoid buying something new every few months. QUADRO saves you money, protects the environment, and grows with your child – step by step, year after year.

Your child’s safety starts with the right materials – and that’s where QUADRO sets the standard. Since 1979, QUADRO has been raising the bar when it comes to safe play. Our time-tested plug-in system creates rock-solid connections that stay strong for years. We use ultra-durable components and certified materials—similar to those approved for food packaging.

QUADRO is completely free from PAHs, BPA, plasticizers, and heavy metals, making it a safe and worry-free choice for your child’s health. Independent testing agencies like TÜV and DEKRA regularly confirm our material quality. You can download a selection of our certifications right here.

QUADRO supports your child’s motor development from as early as six months old.

What really sets QUADRO apart: It’s not designed to wear out quickly – it’s built to last throughout childhood. Engineered with robust material thicknesses and high-quality materials, QUADRO is designed to grow with your child and withstand years of play. And if a part ever gets lost or damaged, you can easily and affordably replace it.

In the first few years of life, children develop their motor skills – laying the foundation for everything that follows: confidence, independence, and a strong sense of their own body. That’s where QUADRO comes in.

Sure, smartphones and gaming consoles are common in kids’ rooms. But they don’t encourage movement, improve coordination, or build body awareness. Instead of discovering the world on their own, kids consume pre-built realities.

QUADRO is here to flip the script – turning passive screen time into active playtime. Climbing doesn’t start with a video. It starts with a grip, a step, and the courage to try – and that’s exactly what QUADRO is built for.

From as early as six months, kids can explore their world hands-on with their first QUADRO models. Our click system encourages grasping, pulling, standing up – and later, climbing, balancing, and imaginative planning. It all adds up to stronger motor skills – and with them, greater self-confidence.

Because when kids discover that they can climb higher, that their creation holds up, that their idea actually works – they build deep trust in their own abilities. And that trust is the key to growing into independent, self-reliant individuals.

QUADRO supports children at this critical stage – with movement, real achievements they can feel, and a system that gives them freedom while still challenging them.
