Foam Cubes for Kids: Safe Play, Creative Building
Share
Foam cubes for kids are soft, safe and incredibly versatile. They support motor skills, spatial thinking and social interaction, whether at home, in nursery or in primary school. The right choice depends on age, size and where they will be used. RIWI® XXL foam building blocks offer particularly wide scope for creative, active and screen-free play.
When children play, they want to build, romp, explore and try things out. For that they need material that keeps up and is safe. Foam cubes for kids deliver exactly that: they are soft and light and have no hard edges or sharp corners that could cause injuries. If you would like a first overview of soft foam building blocks, you will find all the key information there on materials, set sizes and ways to use them. That is why foam cubes are among the most popular toy categories for children's rooms, nurseries and primary schools.
There is a wide choice of products. There are classic play cubes with an edge length of about 16 cm, dot cubes for dice games and learning games, but also XXL soft building blocks of 20 to 50 cm, with which children can put up real structures. Which variant offers the best value depends on age, needs and where it will be used. In this article you will find all the key information so you can make the right decision.

What types of foam cubes are there?
Not all foam cubes are the same. Depending on the intended use, shape, size and material differ clearly. A comparison of the main variants helps you choose.
Classic play cubes have an edge length of about 16 cm and are ideal for dice games, movement games or first building projects. They are light enough for small hands to lift and stack with ease. Compared with other materials such as wood or plastic, foam cubes offer much more safety during wild play.
Dot cubes and learning cubes are designed specially for preschool and primary school children. They show numbers, dots or symbols and can be used for maths, quantity learning games or classroom games. That makes them a useful addition in lessons, but also at home for learning through play.
Soft building blocks and XXL large blocks have edge lengths of 20 to 50 cm and more. With them children build towers, bridges, castles or whole obstacle courses. These blocks are made for building, climbing and romping. Sets that contain triangles, cylinders or arches as well as cubes encourage creativity better than pure cube sets, because they allow more complex constructions and a greater variety of play. Soft foam cubes are also suitable as a safe play aid for volleyball and other ball games indoors.
💡 Tip: If you are unsure which variant offers the best value for money, start with the child's age. In the next section you will find all the information on age recommendations.
Foam cubes by age: Which size is right?
The age recommendation is one of the most important filters when buying foam cubes. The right size makes the difference between frustrating and exciting play.
Children ages 3 and up benefit most from large, soft and light cubes. They are ideal for gripping, stacking and knocking over. Small shapes with lots of individual parts are unsuitable at this age, as they can pose a choking risk.
Children from 3 to 6 can already build more complex structures. Sets with different shapes such as cubes, triangles and cylinders are particularly suitable here. Edge lengths between 20 and 40 cm allow real building projects in which the child can interact with their own body.
Children ages 6 and up benefit from versatile soft building block sets for complex building as well as from smaller learning cubes for dice games and maths at school or at home.

The RIWI® XXL building blocks are recommended for children ages 3 and up. With edge lengths from 20 cm, they make life-size constructions in which children can not only build but also sit, lie and climb. The sets are available in sizes from 12 to 48 blocks, for children's rooms as well as for nursery group rooms. The reviews from families and institutions speak for themselves: over 95% of parents call RIWI® their children's favourite toy.
Safety and material: What to look for when buying
For parents and institutions, safety comes first. In this respect, foam cubes for kids have a clear advantage over blocks made of wood or plastic, because they have no hard edges, no sharp corners and no small parts that could become dangerous.
The material decides: High-quality PU foam (cold-cure foam) is soft, elastic, shape-retaining and durable. It cushions falls, keeps its shape even after intensive use and stays vivid in colour. The colours, including red, blue, orange, yellow and green, stay lively even with frequent use. Cheaper products from other manufacturers often use lower-quality foam that sags or loses its shape faster. Paying attention to workmanship and material quality is therefore especially worthwhile when buying.
⚠️ Important: When buying, look out for the following features:
- TÜV certificates or test marks to European safety standards (EN 71)
- Testing for harmful substances; the cubes should be tested for harmful substances
- A stable shape that cushions falls without tearing or breaking
- Concealed zips, so children do not get caught
- Removable covers that are washable at 30 °C or 40 °C
Covers compared: Faux leather covers are wipe-clean and hygienic, which makes them particularly practical for nurseries and therapy settings. Velour covers are softer and more pleasant to the touch, ideal for the children's room at home. Cubes with a coating are generally more robust and longer-lasting.
The RIWI® XXL building blocks are made of PU foam tested for harmful substances and certified to European toy standards. Velour covers or faux leather covers are available as an option, depending on your needs and where they will be used. You will find regular offers and discounts directly in the RIWI® shop.
Motor skills and creativity: What foam cubes encourage in children
Foam cubes are far more than just toys. They support children's development in several areas at once, and entirely without a lecture.
Gross motor skills: Children climb onto the blocks, jump down and balance across rows of blocks. This strengthens muscles, sense of balance and body control. If you are looking for specific movement games with children, you will find plenty of practical ideas there that can be put straight into practice with foam cubes.
Fine motor skills: Placing and aligning the cubes precisely, holding and turning larger elements and hand-eye coordination when stacking naturally encourage manual dexterity.
Spatial thinking and creativity: Children who build towers, bridges or mazes from foam cubes train their spatial thinking and solve small construction problems along the way. Using different shapes and colours stimulates creativity further.
Social skills: Foam cubes are ideal for group games. When building together, children communicate, negotiate plans and resolve conflicts. This fosters team spirit and language development without any teaching agenda.
💡 Tip: Deliberately let children carry on even when a tower collapses. Experiencing trial and error strengthens self-confidence and problem-solving skills.
Foam cubes in nursery, primary school and therapy
Foam cubes are ideal for use in kindergartens, schools, after-school clubs and therapy settings. They can be used flexibly for learning and movement games and need no long explanation; children understand straight away what they can do with them.
In nursery, large soft building blocks suit movement rooms, group building projects and free role play. Several children can build at the same time without getting in each other's way. If you are looking for more ideas for indoor group games with children, you will find a collection of tried-and-tested activities there for different group sizes.
In primary school, foam cubes can be used for learning activities in maths, for example for sorting, counting or showing quantities. They are also suitable as a break filler or for relaxation in lessons, when children should switch off briefly and move around.
In occupational therapy and psychomotor therapy, soft building blocks are used as a proven tool for targeted support, because they allow movement, body awareness and sensory experiences in a simple way. They are also used in other therapy areas such as speech therapy or curative education, because they encourage communication and interaction in a playful way.
Sets of 24 blocks or more are a good fit for institutions. RIWI® is happy to advise nurseries and schools individually, and there are special offers and terms for larger orders too.

With a 24-block set you get a walk-in castle with an entrance and towers. With 48 blocks, children build a maze, a fortress or several play stations at once. Quieter variations are possible too: several blocks make a cosy cuddle corner or a chill-out couch. With the RIWI® Couch Cover, the construction becomes a real piece of furniture for the children's room.
Care and storage: Foam cubes in everyday life
Foam cubes are in constant use, so crumbs, dust and stains end up on the covers. The good news: care is uncomplicated and keeps the products long-lasting.
Removable covers can simply be washed in the washing machine at 30 °C or 40 °C (delicates). Use a mild detergent, do not bleach, and ideally air-dry to protect colours and material. Small stains can also be wiped off in between with a damp cloth and mild cleaning agent, ideal for nursery life.
There are clever solutions for storage:
- Arrange blocks as a couch: This saves space and becomes a piece of furniture
- Store in the RIWI® Couch Cover: Tidy design, cleared away quickly
- Carry in the RIWI® XXL Bag: Ideal for on the go or moving between rooms
The foam itself keeps its shape even when children jump and lie on it every day. That is workmanship and quality that pays off over the years and justifies the price.
FAQ: Frequently asked questions about foam cubes for kids
From what age are foam cubes suitable?
Large, soft foam cubes are suitable from ages 3 and up, provided they are big enough and pose no choking risk. For children ages 3 and up, cubes with an edge length of about 16 to 30 cm are ideal. From age 3, children can also build, climb and romp independently with XXL soft building blocks.
How many foam cubes do I need?
For a children's room with 1 to 2 children, 12 blocks are a good start. For nursery group rooms or movement areas, 24 to 48 pieces are recommended so that several children can build at the same time.
What is the difference between cheap and high-quality foam cubes?
The difference lies mainly in the material and workmanship. High-quality foam cubes made of PU foam keep their shape even after intensive use, while cheaper products from other manufacturers often sag or fray faster. With covers, too, it is worth looking for careful workmanship, sturdy seams and colourfast materials. Good reviews from other buyers with four or five stars are a reliable sign of quality.
Are foam cubes also suitable for outdoors?
Open-cell PU foam is optimised for indoor use. Occasional use on the terrace is possible, but you should protect the cubes from wet and prolonged sunlight. For outdoors, water-repellent materials with closed-cell foam are better suited.
How do I clean foam cubes properly?
The covers are removable and washable at 30 °C or 40 °C. In between, a damp cloth with mild cleaning agent is enough. Do not let the foam core itself get wet, and always let it dry before the cover goes back on.
Are foam cubes suitable for nurseries, schools and therapy settings?
Yes, particularly so. Foam cubes are ideal for group games, movement games and learning activities in lessons as well as for various therapy areas. For institutions, velour or faux leather covers are recommended because they are particularly durable and easy to clean. For larger orders, RIWI® advises individually and offers special terms.
Foam cubes are among the most versatile products you can choose for children's development. They support motor skills, creativity, social interaction and spatial thinking, entirely without fixed rules and without a screen.
