Materials That Matter


Foamnasium is constructed of only the highest quality covers and foam.

  • Constructed with durability in mind, we use foam that is high in density (density = durability).
  • Using a foam that is firmer in nature means your playset will keep it’s shape over time.
  • All foam is made in the USA, CertiPUR-US certified.


All fabrics used in our covers are tested to be strong, easy to clean, and safe.

California residents see Prop 65 WARNING

Foamnasium is created and intended for indoor use only. Play outside at your own risk.

Our Story

Handcrafted with Care.

Our quality is unmatched and we stand behind every piece we make. We’re not just assemblers, we’re manufacturers! We’ve been fabricating foam since 1952, so you can have confidence knowing we only use high quality goods.

My kids use these ALL THE TIME. One of my favorite purchases. Well worth the investment!

10 month old son loves this thing. High quality and just the right firmness - I can see him playing with this for a long time.

A huge hit, especially on days when we can't go out and play.
