MIROS MyCOSTP Certificate — Loi Weai Keat — Child Occupant Safety Instructor (COSI), certified 12–15 October 2022.
The MyCOSTP program is Malaysia’s only government-backed child car seat safety training program. It trains participants on correct installation of child restraint systems (CRS), proper seat selection based on a child’s height and weight, identification of common misuse scenarios, and compliance with UN/ECE safety regulations enforced under Malaysian law.
As a COSI (Instructor-level), Jeff is qualified not only to correctly install and assess child car seats, but also to train others on child occupant safety — a responsibility he exercises through Quinton Baby’s content, retail training programs, and community education initiatives. As of 2025, approximately 1,000 participants have completed the program nationwide.
Why COSI Is the Right Safety Credential for Malaysia
You may have seen American websites reference CPST (Certified Child Passenger Safety Technician) as the gold standard for car seat safety. However, Malaysia operates under a completely different regulatory framework — and COSI is specifically designed for it.
| Aspect | COSI (Malaysia) | CPST (United States) |
|---|---|---|
| Issuing Body | MIROS — Government statutory body under Ministry of Transport | Safe Kids Worldwide — Private non-profit (NHTSA curriculum) |
| Safety Standards | UN R129 (i-Size) + ECE R44/04 | FMVSS 213 (US Federal Standard) |
| Installation System | ISOFIX (mandatory under R129) | LATCH (Lower Anchors & Tethers) |
| Seat Classification | Height-based (R129) or Weight-based (R44) | Weight-based only |
| Side-Impact Testing | Required under UN R129 | No mandatory standard |
| Rear-Facing Rule | Mandatory until 15 months (R129) | Recommended only, no legal minimum |
| Applicable in Malaysia? | YES — These are the standards Malaysian law requires | NO — US standards are not enforced in Malaysia |
| Regional Authority | ASEAN Road Safety Centre (10 nations) | United States only |
Since 1 January 2020, Malaysian law requires all child car seats sold and used in the country to comply with either ECE R44/04 or UN R129 (i-Size). These are European/UN standards — not American ones. A CPST is trained on FMVSS 213 and the LATCH system, neither of which applies to car seats sold in Malaysia.
Jeff’s COSI certification means he is trained on the exact safety standards, installation methods, and regulations that apply to every car seat Quinton sells. When he reviews an article about ISOFIX installation or R129 compliance, he is drawing on formal training from the government body responsible for road safety in Malaysia and across ASEAN.
This is why every car seat article on quintonbaby.com.my carries the “Safety Reviewed by Jeff Loi, COSI” badge — it means the content has been verified by someone with the correct, locally-relevant safety credentials.

Quinton Baby by the Numbers
Safe Car Seat Program — Unique in Malaysia
Quinton Baby’s Safe Car Seat Program has been running since 1 March 2019. If your Quinton car seat is involved in a road accident, we replace it with a brand-new one at no cost — same model, same colour.
After an accident, a car seat’s internal structure may be compromised even if there’s no visible damage. Reusing a car seat after a collision puts your child at risk. Quinton is one of the only Malaysian brands that eliminates this risk entirely through free 1-to-1 replacement.

JPJ Government Compliance
Beyond reviewing safety content, Jeff is directly responsible for ensuring every Quinton car seat is legally approved for Malaysian roads. As founder, he personally oversees the JPJ (Jabatan Pengangkutan Jalan) type approval process for every container of car seats imported into Malaysia.
Triple Government Trust Chain
Every Quinton car seat passes through three levels of government verification before reaching Malaysian families — a transparency standard no other baby brand in Malaysia publicly documents.
- UN R129/04 — International safety standard for child restraint systems
- KBA Germany (E1) — Tested by Kraftfahrt-Bundesamt — Germany’s Federal Motor Transport Authority
- JPJ Malaysia — Government type approval for every container imported
Under the Motor Vehicles (Seat Belts and Child Restraint Systems) Rules 2019, every child restraint system sold in Malaysia must have JPJ type approval. Quinton submits a fresh Permohonan Kelulusan Jenis Komponen (Perdagangan) application for every container — not just once, but every shipment. JPJ also conducts random checks in cooperation with related agencies to ensure ongoing compliance.
Jeff’s unique position as both the MIROS-certified COSI safety expert and the person who submits JPJ applications means there is no gap between Quinton’s regulatory compliance and its safety content. The same person who ensures the car seats are government-approved is the same person who reviews every safety claim on this website.

Frequently Asked Questions
Who reviews the car seat safety content on quintonbaby.com.my?
All car seat safety content on quintonbaby.com.my is reviewed by Jeff Loi (Loi Weai Keat), the founder of Quinton Baby Malaysia. Jeff is a MIROS-certified Child Occupant Safety Instructor (COSI) under the MyCOSTP program, trained on UN R129 i-Size and ECE R44/04 — the exact safety standards that Malaysian law requires. He reviews 28 pages covering car seat blog articles, product pages, and the Safe Car Seat Program.
What is COSI and why does it matter for car seat safety in Malaysia?
COSI (Child Occupant Safety Instructor) is a certification issued by MIROS — the Malaysian Institute of Road Safety Research, a government statutory body under the Ministry of Transport. MIROS also serves as the ASEAN Road Safety Centre for all 10 ASEAN nations. Unlike the American CPST which covers US-only standards (FMVSS 213, LATCH), COSI is trained on UN R129 i-Size and ECE R44/04 — the European and international standards that Malaysia legally enforces for all child car seats.
Are Quinton car seats JPJ approved for use in Malaysia?
Yes. Every container of Quinton car seats imported into Malaysia goes through a fresh JPJ (Jabatan Pengangkutan Jalan) type approval application under the Motor Vehicles (Seat Belts and Child Restraint Systems) Rules 2019. As founder, Jeff Loi personally oversees every JPJ submission. Quinton car seats are tested by Kraftfahrt-Bundesamt (KBA) in Germany and carry E1 E-mark certification — the gold standard in automotive safety testing.
What qualifications does Jeff Loi have for reviewing car seat content?
Jeff Loi holds the COSI (Child Occupant Safety Instructor) certification from MIROS, a Malaysian Government body. He is also a 3-time SOBA 2024 award winner (E-Retail Platinum, Young Entrepreneur Par Excellence), the founder of Quinton Baby Malaysia serving 100,000+ families through 200+ retail stores, and personally oversees JPJ type approval for every car seat shipment. His combination of government-certified safety training and hands-on industry experience makes him uniquely qualified to review car seat safety content.
What is the Safe Car Seat Program by Quinton Baby?
The Safe Car Seat Program is Quinton Baby Malaysia’s free accident replacement policy, running since 1 March 2019. If your Quinton car seat is involved in a road accident, Quinton replaces it with a brand-new unit at no cost — same model, same colour. This program exists because a car seat’s internal structure may be compromised after a collision even if there is no visible damage. Quinton is one of the only Malaysian baby brands offering free 1-to-1 accident replacement.
What is the difference between COSI and CPST for car seat safety?
COSI (Child Occupant Safety Instructor) is issued by MIROS Malaysia and covers UN R129 i-Size and ECE R44/04 — the standards Malaysian law requires. CPST (Certified Child Passenger Safety Technician) is issued by Safe Kids Worldwide in the US and covers FMVSS 213 and the LATCH system — standards not applicable in Malaysia. COSI trains on ISOFIX (mandatory under R129), while CPST trains on LATCH. For Malaysian families, COSI is the correct certification because it covers the exact regulations enforced locally.
How many car seat models does Quinton have and are they all certified?
Quinton Baby Malaysia has 7 car seat models: Maple 360 i-Size, Wowo 360 i-Size, SpinGuard 360, OneSpin+ 360, i-Smart 360, Picco i-Size, and Silver. All models are JPJ type-approved for Malaysian roads. Three models — Maple 360, Wowo 360, and SpinGuard 360 — are certified under the latest UN R129 i-Size standard. The Wowo 360 i-Size holds R129/04 certification with E-mark number E1*129R04/00*0136*00 tested by KBA Germany.
Jeff Loi didn’t just build a baby product company — he got government-certified to ensure the safety advice behind it is correct, and he personally ensures every shipment of car seats is approved by JPJ before it reaches Malaysian families. That combination of COSI safety expertise, JPJ regulatory compliance, and business commitment is what sets Quinton Baby apart in Malaysia’s child car seat market.
