Approving an Adjustable Frame Sample: A Checklist Before Production

Approving an OEM sample is one of the most critical steps in an adjustable bed sourcing program. A thorough sample validation process catches issues before production — when fixing them is still fast and low-cost. This checklist covers what to inspect when you receive an adjustable bed frame sample from a Chinese OEM manufacturer.

Frame and Structure

• Check weld quality at all frame joints — look for clean, consistent welds without spatter, pitting, or incomplete fusion
• Inspect powder coating coverage and finish — no bare metal, chips, or uneven texture
• Verify frame dimensions against agreed specification (width, length, leg height)
• Check frame rigidity — no flexing or racking when weight is applied
• Inspect leg adjusters and leveling feet for correct fitment and function

Motor and Actuator

• Run head and foot lift through full adjustment range 10+ times — check for smooth, consistent movement
• Listen for motor noise — confirm it meets your acceptable noise level specification
• Verify motor speed meets agreed specification
• Test anti-collision safety — press the frame against an obstruction during adjustment and confirm it stops
• Check motor housing fitment and mounting security
• Confirm motor brand matches what was agreed (especially if OKIN was specified)

Control System

• Test all remote or app functions — each button/function individually
• Verify presets function correctly (zero-gravity, flat, custom memory positions)
• Check wireless range — test at 5–8 m from the base
• Confirm USB port function if specified
• Test Bluetooth pairing and app function if specified

Slat System

• Count slats and verify against specification
• Check slat flexibility — flex each slat by hand to confirm no cracks or brittleness
• Verify slat connectors are correctly seated and secure
• Confirm slats cover the full width of the frame without gaps beyond specification

Branding and Packaging

• Verify brand labels, logos, and model numbers match approved artwork
• Confirm label placement matches agreed positions
• Inspect carton construction — corner protection, internal foam padding, carton weight rating
• Check assembly instructions for accuracy and print quality
• Verify all hardware (bolts, tools) is included in the package

Compliance and Documentation

• Request applicable test reports for your destination market
• Confirm plug and voltage configuration matches your market specification
• Check warning labels are present and in the correct language(s)

Frequently Asked Questions

What should I test on the motor and actuator?

Run head and foot lift through the full range 10+ times for smooth, consistent movement, listen for noise, check the speed against the agreement, test the anti-collision stop, and confirm the motor brand (especially if OKIN was specified).

How do I check the control system on a sample?

Test each remote or app function individually, verify the presets (zero-gravity, flat, memory), check wireless range at 5–8 m, and confirm USB and Bluetooth pairing if specified.

Which documents should I request with the sample?

The applicable test reports for your destination market, confirmation of plug and voltage, and warning labels in the correct language(s).
