Soft Building Blocks: The Guide to Soft XXL Blocks

Key Takeaways

Soft building blocks all look similar at first glance: colourful, soft blocks for stacking and building. But as soon as a child climbs on top or a tower grows above head height, the difference shows. Some XXL soft building blocks give way under weight, slide away while building or lose their shape after a short time. In our guide to foam building blocks we explain what really matters when it comes to material, grip and care, so that your purchase isn't a gamble and the toy lasts. This article compares products for children ages 3 and up and older children alike, to make your choice easier.

Soft building blocks are large-format foam blocks, designed for children ages 3 and up. Unlike hard plastic toys, they have no sharp edges and weigh next to nothing, so even a small child can carry a piece alone without trouble. That is exactly what makes foam building blocks a tool for creative, active play: stack, build, knock down, start again. Unlike toy cars or construction sets made of hard plastic, XXL soft building blocks come without small parts that can get lost in the children's room.

The right age shapes what you expect from a set. At age 3, children mostly stack simple towers, from age 6 more complex constructions appear, and up to age 8 open-ended building play stays appealing for many children. The age of siblings or of the group ultimately determines which set makes sense, but whatever the age, the basic idea stays the same: movement and imagination instead of screen time. Foam building blocks remain a versatile everyday toy for children ages 3 and up as well as for older children up to age 8, and from age 6 children usually also have more stamina for building complex structures. The way foam building blocks are made differs greatly between brands, above all in the density of the foam core. That is why soft building blocks suit children ages 3 and up as well as school-age children, as long as the set size fits the group.

RIWI® XXL building blocks are a good example of this category of toy. The blocks are made from our own PU foam formula, uncoated and light, yet sturdy enough for tall structures. While playing, children learn on the side how much weight a tower can carry before it topples, and without the risk of wood or hard plastic toys.

The market for foam building blocks can be roughly divided into three categories that differ in purpose and construction. XXL soft building blocks often differ in the number and shape of the individual pieces, and they also impress with the size of each element. The advantages of foam building blocks show most clearly in continuous use over several years.

The real difference between good and weak foam building blocks, however, rarely lies in the shape but in the material. Density and recovery determine whether a piece returns to its size after someone sits on it or keeps a dent for good. Uncoated material feels softer, while coated variants are often more resistant to moisture but a little firmer to the touch. Unlike rigid climbing frames, foam building blocks can be rearranged at any time, and blocks for outdoor use should also be weatherproof enough.

In nurseries, schools and therapy centres, different criteria apply than in the children's room. A movement course has to carry several children at once, day after day, without safety suffering, regardless of the group's age. This is where it becomes clear why load capacity is no side issue: RIWI blocks hold up to 110 kg, enough for group play with several children on one tower.

Robust covers are a must at this level of use. The RIWI® Velours Covers offer more weight and grip for continuous use, while the RIWI® PU-Leder Covers are wipeable and particularly hard-wearing, ideal for facilities with heavy use and for outdoor areas. Where other providers rely on simple imitation leather, a genuine PU leather cover is all about abrasion resistance, especially when several groups of the same age play on it every day.

Before you decide on a set, it is worth looking at three points that are rarely visible in the product photo. Foam building blocks differ mainly in density and workmanship, not in mere appearance.

Cheap soft building blocks often save on exactly the material. The result: foam building blocks that turn soft after a few weeks, give way under weight or slide away while building because the surface is too smooth. With RIWI, the high surface friction of the material makes the blocks cling to each other, with no Velcro and no magnets. Tip: if you are unsure, order the smaller set first and add a second set in the same colours later. Each set provides a solid foundation of shapes.

With a set that has removable covers, cleaning is simple: take off the cover, wash at 30 °C, and let it dry without fabric softener. A good cover often makes the biggest difference in everyday life. For facilities with heavy footfall, that is a decisive advantage over hard plastic toys, which can be wiped down but not cleaned thoroughly. Important for nurseries and schools: washable covers can be swapped quickly between user groups, without a whole set having to dry for hours. Foam building blocks with robust covers are therefore particularly suited to heavily used groups.

A note on delivery: XXL soft building blocks usually arrive packed in compressed form. With XXL soft building blocks it is always worth keeping an eye on the recovery time after unpacking. After unpacking, the blocks expand to their full size within around 20 minutes, and in individual cases this can take a little longer. This is normal and not a quality defect in this product.

The set size should depend on the number of users and their age, not on the cheapest offer. A child building alone in their room often gets by with a smaller set of 12 or 24 pieces. As soon as siblings join in or a movement room in a nursery is being equipped, the larger set of 36 or 48 pieces pays off, because more pieces mean more shapes, more colours and more complex constructions.

In the online shop, a filter by set size helps with the first selection, after that it is mostly everyday life that decides. The four colours blue, yellow, green and red are evenly mixed in every set, which makes it easier to add another set in the same colours later. Compared with smaller blocks, XXL soft building blocks need a bit more storage space, but they also offer more building height. If you are equipping a whole group, the RIWI® XXL building blocks give you a system that can be expanded as you like whatever the age, from a single set to the complete equipment for a movement room. Foam building blocks in a larger set also offer more ways to combine them for groups.

The real value of foam building blocks only shows in play itself. The same shapes produce completely different structures, depending on imagination, age and mood of the day. From the first tower to a big building with several rooms, almost anything is possible, and not all of it has to be planned in advance.

This open-ended play without fixed instructions strengthens creativity and problem-solving alike. Children try out what holds and what topples, entirely without a screen. Climbing is one of many children's favourite ways to play with foam building blocks. A few balls add to the play environment for extra throwing games between the towers, bringing further play options into the same collection of structures. Depending on the mood of the day, very different results come out of building.

For parents, open-ended play means that one set produces new constructions over months, not just a single result. If you like, combine the larger set with the RIWI® XXL Bag as a beanbag and storage in one, or turn foam building blocks with a matching cover into a play sofa for the children's room.

Yes, most sets are designed for ages 3 and up. At this age, motor skills are developed enough to stack piece by piece independently, and the material is light enough that nothing can happen if a tower falls over.

You can wash removable covers at 30 °C, without fabric softener. With most products, the foam core itself does not go in the washing machine; a damp cloth is enough for in-between cleaning.

Yes, with robust covers such as velours or PU leather, foam building blocks are suitable for continuous use in nurseries, schools and therapy, whatever the age of the group in question. Load capacity of up to 110 kg and wipeable surfaces make them practical for everyday use. Simple imitation leather rarely keeps up here; facilities mostly choose more robust cover options deliberately.

Soft building blocks seem interchangeable at first glance, but in everyday use it quickly becomes clear which set lasts and which gives way. Foam building blocks that meet these points impress in the long run more than any supposed bargain. When buying foam building blocks, what counts in the end is above all the workmanship, not the look in the product photo. Soft building blocks remain a toy that can be combined anew again and again. If you pay attention to material, grip through surface friction and washable covers, you buy a set that lasts years instead of weeks, whatever the age of the children playing with it. The RIWI® XXL building blocks combine exactly these points: our own foam formula, load capacity of up to 110 kg and set sizes for every family and every facility. If you are looking for even more building ideas for older children, our guide to giant building blocks offers further inspiration for particularly large constructions.
