Choosing the perfect school backpack is not easy, as there are so many proposals, both for the little ones and for the older ones. Precisely for this reason we decided to dwell on this particular category, which is part of the large group of most requested and sold backpacks.

School backpack or trolley?
The main problem, which concerns a very high number of students of all ages, is the weight of school backpacks. The books, notebooks and all the accessories needed for normal school activities do nothing but increase the weight of their container. The problem is not the backpack, since their weight is less than a pound (at most, it reaches 4 lbs for backpacks with wheels), but it is the quantity of educational material that is put inside.
It is primary school children who are most affected by this problem: their delicate physique cannot bear the weight of backpacks filled in all their space well, and the consequences for the spine can also be disastrous. Experts say that the weight of the backpack should be between 12 and 15% of the body weight of the person concerned, but almost always goes further. Definitely beyond!
What to do? Backpacks with a padded and ergonomic backrest can facilitate the transport of a large number of books and notebooks, distributing the weight evenly over the entire back.
Unfortunately, sometimes this is not enough. Here come to the rescue of the smallest trolley school bags, easily transportable thanks to the solid wheels positioned in the lower part. Yes, they can be considered as real school bags.
Are they better than shoulder-less models? It depends on the use you intend to do and on the subject who will use them. The trolley school bags have been designed to help the smallest school children in kindergartens and primary schools (and middle schools), while they are more uncomfortable for those who already attend high school second level.
What to choose? Better school trolley bags or a classic model? We have already answered this question, even if in an indirect way, but to have a more complete answer we can analyze the disadvantages and advantages of these particular models:
- Advantages : reinforced bottom to support a high weight and sturdy wheels that allows you to carry them almost anywhere without straining the back. Very useful and recommended for those who usually do long walks from home to school. Another advantage is the protection of the material contained in them from humidity: the lower plastic part protects the fabrics from water. Even on wet surfaces it is possible to make the backpack walk, avoiding getting the lower part soaked.
- Disadvantages : the greater weight of the structure (compared to the classic ones), and the higher price are the only two limits of these models. The lower part, usually made of solid plastic, the reinforcements on the back and the wheels increase (by just over a kilogram compared to the shoulder models) the weight of the trolley school bags. Weight that should not be considered as a boulder that will arch the back of the little ones, but which must always be taken into consideration, since they can also be carried on the shoulders.
Do we recommend trolleys school bags? Yes, but only for the little ones who will have to face long walks to reach their school, thus avoiding to load the weight on their back. The trolley school bags are considered, in any case, friends for the spine. Even the pediatricians have raised their thumbs, as a sign of approval, for these wheeled backpacks.
Recommended age for trolley use
Researchers at the University of Granada conducted a survey to investigate the issue related to the weight of school backpacks, often real hardly transportable blocks. The survey was carried out on several elementary and middle school children, forced to carry, every day, a weight far greater than 12/15% of their body weight.
Without going into the details of the research carried out, we can safely state, reporting what was said by the researchers of the Spanish University, that trolley school bags represent the least harmful choice for the back of young children.
This does not mean that they can be filled in a reckless way, since the limit, indicated with the percentages described above, should in any case always be respected. The trolley is the ideal solution to improve posture and avoid worsening already compromised physical situations.
What is the recommended age for trolley school bags? These models, more and more beautiful and comfortable, are practically perfect for small children who, wearing beautiful aprons, are ready to face long mornings in kindergartens or elementary schools.
They can also be joined by older middle school students. This specific technology has been specifically designed to protect their most delicate physique.
For about 10 years, school trolley backpacks have literally climbed over, thanks also to the quality of the materials used to create a structure designed down to the smallest detail, those that can be defined as classic backpacks.
In practice, from the backpacks that resumed the shapes of the shoulder bags used by climbers after the Second World War, we moved on to more gentle models in the lines, up to these models even with wheels, fixed or removable. Design and technology have also led to major changes in the world of school accessories.
Differences between the fixed and removable trolley backpack
Nothing to add in terms of practicality and comfort, but we can say something more about the structure of these specific models. Not all trolley school bags are the same, as some may have a fixed, removable, other wheeled structure.
The differences between the fixed and removable trolley backpack mainly concern the back part. Let’s try to make things a bit clearer:
1. Both have a rigid rear and lower structure that ends with plastic wheels. The latter, as far as the best models are concerned, can even be depreciated, guaranteeing even easier transportation.
2. The handle is always (unless you decide to spend very little for a low-quality model) built in resistant materials, to withstand even the strongest tensions. The handle is always removable (telescopic), so as to make the transport of the school backpack even easier.
3. The trolley is the link between the fixed and removable models. It is usually an integral part of the school trolley, but this is not always the case. The first models launched on the market could in no way be modified in their structure, but today there are many trolley backpacks of the best brands that can be disassembled and reassembled with extreme ease.
Just remove the special hooks and the trolley backpack turns into a normal backpack in just a few seconds. And it is precisely in this case that we can speak of differences between the two models: the models with fixed structure usually err on the part of the back, less padded and with not exactly excellent technical characteristics. What has just been said is normal, given that they are backpacks intended only for transport on wheels.
Our advice is to choose school trolley bags with removable cart, more versatile and almost always with padded and ergonomic back, so as to ensure maximum comfort when carried on the shoulder thanks to the padded shoulder straps. The best models are also equipped with abdominal belts to lock the backpack and make it adhere perfectly to the back.
Now let’s take a look at the dimensions of these comfortable backpacks with school wheels:
- The size of the school trolley bags (for elementary school) is around 11x10x5 inches. In most cases, they have a large internal compartment and two or more external pockets with zip closure.
- Trolleys for junior high-school students can have a size of 18x14x8 inches, with handles that can even reach 35 inches above the ground. The internal volume, for the larger models, can even reach 40 liters and the pockets, both internal and external, are significantly higher in number.
