Baby High Chairs That Meet Japan's Highest Safety Standards
What Makes a High Chair Safe? Key Safety Points Parents Often Miss
It is easy to choose a high chair based on looks or price. But because high chairs are raised off the ground, the risk of tipping or falling is always there.
In Japan, there is actually no legal requirement for baby chairs to meet safety standards. That is why choosing a chair with proven safety — not just one that looks sturdy — is a meaningful first step in protecting your child at mealtimes.
What Is the SG Mark? A World-Class Safety Standard Set by Experts
The SG Mark is a seal of safety recognised by independent Japanese testing experts. It covers rigorous checks including:
・Tip-over resistance — will the chair stay upright even if a baby kicks the table?
・Structural strength — can it withstand daily use by a growing child?
・Gap safety — are pinch points between components eliminated?
Only three wooden high chair makers in Japan have earned this certification. Yamatoya is one of them.
High Chair Safety Standards: How SG, ASTM and EN Compare
Around the world, there are several respected safety standards for children's furniture — Japan's SG Mark, the US ASTM and Europe's EN among them. None is superior to the others. Each simply focuses on a different aspect of protection.
SG Mark (Japan) is a trusted certification focused on “practical safety.” It considers both the user’s experience and the manufacturer’s perspective to create clear, effective standards.
ASTM (US) and EN (Europe) set rigorous benchmarks for tip-over prevention and the elimination of harmful substances. The EN standard is trusted globally, and several countries in Asia have adopted it as well.
What matters most is whether a chair is designed to meet these demanding levels of safety. When comparing options, look for which standards a product has been tested against.
How Yamatoya Earns the SG Mark
Yamatoya pursues strict certification with the same care as building a chair for our own children.
・Solid natural wood — the weight of real timber creates a level of stability that plastic simply cannot match, helping to prevent tipping.
・Precision joinery — sturdy construction built to support a growing child's increasing weight, year after year.
Not just safe-looking. Proven safe. That is our promise.
How to Prevent Falls: 5 Safety Checks for Choosing a High Chair
- Stability — Does the chair stay firmly in place, even when your child moves around?
- Gap design — Are gaps between 5 mm and 12 mm eliminated to prevent trapped fingers?
- Weight capacity — Is the frame strong enough to support your child as they grow? (More detail in the next section.)
- Materials — Are the paints and finishes safe if mouthed, meeting food-contact safety standards?
- Footrest adjustment — Can you keep your child's feet flat and supported, which helps with chewing and posture?

Here are Yamatoya's high chairs that have earned SG Mark certification. Our other models are also designed to meet the same level of safety, even where formal SG certification does not apply.
Affel: Colourful, Capable and Built to Hold Up to 100 kg
A favourite for its soft pastel colourways, the Affel supports up to approximately 100 kg — so it grows from high chair to everyday seat well into adulthood. Fine seat and footrest adjustments keep your child in a safe, well-supported posture at every stage.
