SMAI (Sia & Mak Amusement Inc.) is the company known for its high-quality production of trampolines all over Europe for more than 12 years. Established and introduced the amusement concept in the Philippines under the name BUBI Trampoline in 2011.


All of our trampolines carry the CE safety mark and are EN 71 compliant.  Some have undergone additional testing and have received certification in the form of GS & ASTM International marks.

CE Safety Mark

The CE Mark is mandatory for all products sold in the European Economic region.  The CE mark indicates that a product conforms to the legal requirements laid out in the European Union (EU) Directive with respect to safety, health, environment, and consumer protection.

All products sold within the EU must carry the CE mark or they cannot be sold.   Each EU country inspects equipment and documentation to make sure that a product conforms as required.

EN 71

This is European safety standard for toys, compliance to which is a legal requirement for all toys sold within the European Union.

GS Mark

The GS Mark is a voluntary certification and demonstrates compliance with the German Safety of Equipment Act, with only those products which fall within the scope of the act eligible to bear the GS Mark.

Independent product testing is completed by specific labs which are accredited by the Zentralstelle der Länder für Sicherheit-ZLS (Central Office of Safety of the German Länder). The GS Mark can only be awarded by ZLS notified certified bodies. Likewise, the product production process must be audited by the certification body.

As the GS certification evaluates a representative sample of the product, there is a high acceptance of the GS Mark throughout the EU.

ASTM International

The American Society for Testing and Materials (ASTM) is an international standards organisation that develops and publishes technical standards for a wide range of materials and products.

Compliance to these standards is not compulsory and is not enforced.
