Specifying wholesale 3 function manual home care beds with mattress supplier for Wholesale and OEM Orders

Consistency depends on the crank‑drive geometry and the mattress‑frame interface; a 2 mm shift in the backrest pivot changes the effective lift angle by 1.5°, which alters patient positioning and caregiver effort.

Deflection under load governs the long‑term feel of the bed; a 30 kg static load on the knee‑break section should not exceed 4 mm permanent set after 10 000 cycles, otherwise the mattress will develop a permanent ridge that compromises pressure redistribution.

Assumptions Buyers Should Stop Making

Many importers treat every manual three‑function bed as interchangeable, yet the crank‑handle torque, side‑rail latch geometry, and mattress‑deck thickness vary by up to 15 % between factories.

• Assuming a single mattress SKU fits all deck profiles – deck thickness ranges from 30 mm to 45 mm, changing the required foam compression rating.
• Neglecting crank‑handle ergonomics – a 12 Nm peak torque is comfortable for most caregivers; 18 Nm leads to early fatigue and higher return rates.
• Overlooking side‑rail clearance for IV poles – a 5 mm gap difference forces a redesign of the rail bracket.
• Expecting identical powder‑coat adhesion – salt‑spray results differ between 48 h and 96 h exposure, affecting warranty claims in coastal markets.

Working as a Production Partner, Not a Catalogue Supplier

The interface between parts determines whether a private‑label program stays on schedule; we lock drawings, material certs, and packaging artwork in a single change‑control register before the first press run.

What Gets Checked Before Shipment

Care, Storage and Service Life

Store frames upright on pallets with a maximum stack height of two units; excessive stacking compresses the mattress foam beyond its 30 % recovery threshold, leading to permanent sag.

Mattress covers are removable and machine‑washable at 60 °C; replace the cover after 30 wash cycles or when the waterproof laminate shows delamination > 2 mm.

Questions Buyers Ask Before Ordering

• What is the minimum order quantity for a custom colour? 50 units for OEM colour match; 200 units for ODM tooling.
• Can the crank handle be swapped for a low‑torque version? Yes – a 10 Nm handle is available as a drop‑in replacement; requires a new handle mould (lead‑time 20 days).
• How are mattress firmness levels specified? Provide target ILD (Indentation Load Deflection) range; we validate with a 25 mm indenter at 25 % compression.
• What documentation accompanies each shipment? Packing list, CE‑type declaration of conformity, material certificates for steel grade and foam density, and a batch‑traceability QR code.
• Is there a spare‑parts programme for the crank assembly? We stock worm gears, handles, and side‑rail brackets for five years post‑production; order via the same SKU prefix.
