Critical Specifications & Material Requirements

The Spring: Miniaturized and Corrosion-Proof

• Spring Diameter: Must be very small. Target under 15mm (approx. 0.6 inches). These are often called

•  "micro-springs" or "mini-springs."

• Spring Height: Typically between 1.5 to 2.5 inches for a pillow application.

• Wire Gauge: Very fine, likely in the range of 19-21 gauge.

• Material & Corrosion Protection: This is the most critical part. Standard powder coating can be too thick

•  for micro-springs and may not survive repeated washing.

  • Best Option: 304 or 316 Stainless Steel. This is the ultimate solution for washability. It is inherently rust-

  • proof and can withstand repeated immersion in water and detergent. It is more expensive but non-

  • negotiable for a true washable product.

  • Alternative: High-Carbon Steel with Advanced Coating. If stainless is cost-prohibitive, the wire must be 

  • double-dip galvanized and then coated with an extremely flexible, food-grade, waterproof polymer coating.

  •  This is less ideal as coatings can theoretically be compromised.
