Play safely

Caret Down

If you want to use Stapelstein® products for balance games and for courses, it is best to do so on a level and non-slip surface. Stack the Stapelstein® elements only as high as you feel safe. We recommend that you stack a maximum of 3 elements if you want to climb a tower on foot.

Products from Stapelstein® are waterproof and can be taken into the water. However, they do not replace a buoyancy aid! Young children must be supervised when playing in the water with products from Stapelstein®.

Pointed objects and surfaces such as scissors, stones, knives, nails, wire or small pointed children's teeth can leave permanent marks on Stapelstein® products. Particularly severe damage can affect the stability.

Love these!!

My 8 month old daughter has really enjoyed our stapelstein order! From a developmental perspective they’ve been great - we stack them, organize them by color, she uses them to pull herself up and work on standing, and more. Love!!

Tristan Foster
Worth it!

They’re a splurge most definitely, but we’ve had endless fun since purchasing! I know they’ll grow with my kids aged 6-1 for years to come. The quality feels substantial. Very pleased so far.

Krystina Rush
Worth every penny!

This is the one toy that my children play with every single day. It keeps them active and creative. We love Stapelstein!!
