Overview
ISO 9221-1:2015 - Furniture - Children’s high chairs - Part 1: Safety requirements specifies safety requirements for free‑standing children’s high chairs intended for children aged 6 months to 36 months. The standard is intended to minimize accidents from normal use and reasonably foreseeable misuse. It covers construction, materials, restraint systems, locking mechanisms, stability, information and packaging. Products that can be converted into items covered by other ISO safety standards are expected to comply with those additional standards as well.
Key topics and technical requirements
- Scope and purpose: Safety requirements for high chairs that elevate a child to approximately dining table height and are used by children capable of sitting unaided.
- Materials and surfaces: Accessible materials must be clean, free from infestation and comply with relevant chemical migration limits (referenced: EN 71‑3).
- Construction and edges: Exposed edges and protrusions must be rounded/chamfered and free from burrs or sharp edges.
- Holes, gaps and openings: Limits on accessible openings (e.g., no holes/gaps 7–12 mm deeper than 10 mm; restrictions on openings above the seat that allow penetration by the small torso probe).
- Moving parts & squeeze/shear points: Requirements to avoid shear and squeeze hazards; specific clearance rules for parts under spring or powered forces (e.g., minimum distances or maximum safe closures such as 18 mm / 5 mm exceptions and 12 mm closure limits where applicable).
- Locking mechanisms: Mandatory locking devices to prevent folding during use, guard against incomplete deployment and unintentional folding; requirements for durability and strength.
- Restraint systems: Definitions and requirements for integral harness, crotch restraints, waist belts/straps; differentiation between active and passive restraint systems.
- Stability: Stability assessments for forwards, rearwards and sideways tipping; consideration of footrest and tray effects.
- Additional requirements: Castors/wheels, structural integrity, durability tests, packaging, marking and instructions for use including mandatory warnings.
Applications and users
- Manufacturers and product designers developing children’s high chairs to ensure compliance with international safety expectations.

- Retailers and importers verifying product safety and labeling before market placement.
- Regulators and procurement professionals referencing recognized safety criteria for consumer protection.
- Product safety engineers and standards consultants advising on hazard mitigation and documentation.
