  • Low Maintenance – Powder-coated steel doesn’t corrode easily and requires little upkeep. Just wipe the hook on the bed rails clean.

Cons of hook-in headboard and footboard brackets

  • Heavy – Steel rails have more weight than aluminum or wrought iron. But lighter than wood rails, heavy-duty metal bed frame provides more stability.

Wrought Iron Bed Rails

Aluminum Bed Rails

Aluminum strikes an optimal balance between affordable pricing and low maintenance. Let’s examine its merits:


  • Lightweight – Weighs far less than steel and iron rails, making handling easier.
  • Corrosion Resistant – Thick powder-coated aluminum on bed frame rails doesn’t rust or corrode. Minimal upkeep is needed.
  • Designer Styles of Headboard and footboard brackets – Sleek aluminum grades enable modern forms like angular frames, tube designs, etc.


  • Lacks Ornamentation – Doesn’t have the graceful curves of wrought iron that allow decorative flourishes in heavy duty bar designs.
  • Dents Easily – Softer than steel so more prone to dings and small abrasions. But these don’t affect structural integrity.

  • Extend rail length to equal mattress width. Adjust telescoping tubes, ideally around 1.5 inches thick, snuggly around the mattress circumference without pinching or leaving gaps wider than 2 inches.
  • For split mattresses, allow for the center gap by installing two pairs of narrow rails with space in the middle rather than spanning across with one uninterrupted rail.
