Mailesi Montessori Sensory Shape Sorter Activity Cube for 12–18 Months

The essentials

If you’re shopping for a first “learning toy” around the 12–18 month stage, this Mailesi Montessori-style sensory shape sorter activity cube is built around a simple idea: put shapes in, pull them out, and put them back. On paper, that kind of repeatable task tends to suit toddlers who like hands-on play, because it keeps giving them small wins.

The toy is made as a sensory box/bins-style cube with a set of elastic bands in soft fabric, plus shape-sorting pieces and textured building blocks. Depending on what your child prefers, you can lean more into the shape matching, the pulling/replacing action, or the sensory side (textures, colours, and the rattle/shake element).

What it helps with (and what it doesn’t)

This product is aimed at early developmental skills that come up again and again in this age range: fine motor practice, dexterity, hand–eye coordination, and basic shape and colour recognition. It’s also designed to encourage problem solving, because the child has to figure out how to get each shape into the right opening and then work out how to remove it.

It’s worth keeping one limitation in mind: toys like this aren’t “autism therapy” or a guarantee of progress on any one skill. What they can do, if they fit your child’s interests, is provide structured play time that’s engaging enough to repeat. If your toddler doesn’t enjoy sorting/feeding movements at all, the activity cube may feel like it’s fighting their current play preferences.

Key features you’ll likely notice during play

What stands out here is the way the cube offers more than one style of activity. There are elastic bands covered in soft fabric, a side that works like a shape sorting board, and textured blocks intended to be easy for small hands to grip.

There’s also a clear “growing challenge” approach with different levels: the design includes a simpler single-row sorting option for younger toddlers starting around 12 months, and a more demanding multi-row arrangement intended to be used as skills develop closer to 18 months. That’s a sensible way to extend interest rather than having a toy that only works for a short window.

Where it shines day to day

If you need something that can keep a 12–18 month old occupied without too much set-up, this is pitched as a travel-friendly option. The sensory box is described as lightweight and convenient to pack into a diaper bag, which matters if you’re dealing with car journeys, trips out, or outdoor days like picnics.

There’s also mention of bath play or even sand/sea-style play, which could be useful for families who prefer fewer “one-use” toys. And because the cube is built around repeated putting-in and pulling-out, it can be the kind of toy that earns its place in daily rotation rather than becoming a novelty.

Example of use: you sit with your toddler, pick one shape (say the round piece), show how it goes into the matching opening, then let them try pulling it out and repeating. If they manage to replace it successfully, you’ve basically created a mini “turn-taking” routine without needing any complicated instructions.

Materials, safety, and practical considerations

The toy is described as using BPA-free ABS material for the white sensory bin, and it’s said to meet US and EU toy standards. It also claims smooth edges and “no choking hazards”, while the elastic bands are described as soft so they shouldn’t hurt during the pulling action.

That said, with any toddler toy that includes small components, it’s still smart to check the pieces are secured and to supervise during play—especially if your child is in a stage where they like to mouth objects or move pieces away from the intended area.

Who it’s for (and who may want to skip it)

It makes sense if you’re after an activity cube-style shape sorter that combines sorting with sensory textures and an elastic-band pulling action. It suits parents who want a toy that supports practice through repetition—especially for toddlers around 12 months gradually moving toward 18 months.

It may not suit you if your child isn’t into sorting shapes, doesn’t tolerate the resistance/pulling motion of elastic bands, or already prefers different types of toys (for example, purely push/pull or story-based play). If you want something very open-ended with no “matching task”, this one might feel more structured than you’d like.

Buying verdict

Is it worth it?

A solid buy if you want a travel-ready Montessori-inspired shape sorter that’s designed to scale from a simpler single-row sorting setup toward a more challenging multi-row one. The combination of textured blocks, elastic-band sensory play, and shape matching is a practical way to keep toddlers engaged while working on fine motor skills and early shape/colour recognition.

You may want to skip it if your child doesn’t respond well to sorting or repeated “put in / pull out / replace” tasks, or if you’re seeking something fully open-ended rather than task-led. Before ordering, it’s also worth double-checking whether your child is at the right developmental stage for hand control and interest in matching shapes, because toys in this category can be very much “right time or it won’t land”.
