16 CFR 1233 – Safety Regulations for Desk Chairs

What is a portable hook‑on chair (tableside chair)?
A portable hook‑on chair (table‑side chair) is a legless seat for children who can sit independently, designed to position the child at a table with the tabletop as the eating surface. The chair is supported solely by the table to which it attaches. It is suitable for children aged 6–36 months weighing ≤37 lb (16.8 kg). Typically, it consists of fabric over a lightweight frame with an attachment mechanism; some fold for storage/transport, and others include a detachable tray for use with the table.
What is the purpose of the portable hook‑on chair standard?
This standard prevents injuries from chairs detaching from or breaking off tables, and from tables and chairs tipping over together.
Applicable Standards
16 CFR 1233 Safety Standard for Portable Hook‑On Chairs
ASTM F1235-18 Standard Consumer Safety Specification for Portable Hook-On Chairs
What are the specific requirements?
ASTM The standard’s general requirements for portable hanging chairs include the following:
1. Cusp test requirements;
2. Testing requirements for small components;
3. Restrictions on lead content in paints;
4. Requirements for wooden components;
5. Requirements for pins and locking mechanisms;
6. Requirements for preventing cutting, shearing, and crushing (including when separating from the workbench support surface);
7. Requirements for covering exposed helical springs;
8. Opening size requirements;
9. Warning label requirements;
10. Requirements for protective components; and
11. Marking, labeling, and descriptive documentation requirements.
Additional performance requirements include:
12. Chair drop test: After the drop test, the chair positioned at the table edge shall not present any mechanical hazards, such as sharp points, sharp edges, or small parts.
13. Static load, used to test whether the hook‑type chair is sufficiently robust to support approximately three times the weight of a child expected to sit on the seat.
14. Seat and seat-back separation test: Determines whether the seat and seat back are sufficiently robust to withstand the forces they will experience during use.
15. Chair bounce test, simulating a child bouncing up and down on the chair.
16. Chair pull/push test to verify that the chair at the table edge does not detach from the test surface under various forces and loads.
17. Restraint System Performance and Testing Requirements: The active restraint system shall secure the child in the seat at each manufacturer‑recommended seating position, and the restraint system and its locking mechanism shall be tested to ensure they do not fracture, separate, or release the occupant when subjected to various forces.
18. Opening and passive hip restraint system requirements: A passive hip restraint system is required to reduce the likelihood of injury or death resulting from a child slipping through or becoming trapped in the opening.
19. Shear and squeeze detachment tests are designed to reduce the risk of injury to children caused by rotational forces when one side (the clip) of a hook‑on chair detaches from the table.
Additional CPSIA requirements for portable hook‑on chairs
Portable hanging chairs must meet requirements for surface coatings, lead content, phthalates, testing and certification, registration cards, and traceability labels.
1.Surface coating: Paint or surface finishes shall not contain lead exceeding 90 ppm (0.009%).
2.Lead content: Total lead in any accessible component shall not exceed 100 ppm (0.01%).
3.Phthalates: Plasticised components shall not contain more than 0.1% of any of the eight restricted phthalates (DEHP, DBP, BBP, DINP, DIBP, DPENP, DHEXP, DCHP).
4.Testing and certification: Like all products primarily for children 12 and under, hook‑on chairs must be tested by a CPSC‑accredited third‑party lab. Based on test results, the domestic manufacturer (or importer, if no domestic manufacturer) must issue a Children’s Product Certificate (CPC).
5.Product and packaging labelling: Durable infant/toddler products (e.g., portable hook‑on chairs) must bear permanent labelling, including traceability labels, on both the product and its packaging.
6.Product registration card: Additional markings and a registration card must be attached to the product.
If the information required for the traceability label and the registration card overlaps, a single marking on the product may satisfy both, but the traceability label must still appear on the packaging.
The U.S. market has strong demand for infant products, but regulations are stringent. SATISFY provides compliance guidance for infant and child products; contact SATISFY customer service for more details.
