A set of foam blocks is easy to make and a fun sensory toy for toddlers. Foam blocks can be used for building, sorting, stacking and so much more. With just a few pieces of 1 inch chair foam you can provide lots of opportunity for learning through play.

Supplies for DIY foam blocks:

We had some pieces of chair foam left over after making new round cushions for some wooden chairs. The scraps included several triangular-shaped pieces from the corners. This provided the inspiration for a set of foam building blocks!

How to make your  DIY foam blocks for toddlers: 

  1. Outline basic shapes on the foam slab with a marker. Cut out the shapes. A pair of regular-sized scissors is needed to cut through the foam’s thickness.
  2. Label the shapes with self-adhesive foam, in different colors and shapes.
  3. If you don’t have foam shapes, you can use letters or numbers, or any other self-adhesive stickers.

A glue gun may be needed to apply the stickers if they do not stick securely to the foam on their own.

Instead of applying stickers, you can encourage your toddler to color the blocks with markers, or simply leave them plain!

Labeling the foam blocks with colors and shapes provides additional play value.
