Did you know there are different types of steel springs inside mattresses?
Each type affects comfort and how we recycle it.
Here are some common ones we see during dismantling:
🔹 Bonnell Coils – Traditional hourglass-shaped springs
🔹 Offset Coils – Similar to Bonnell, but hinged for better support
🔹 Continuous Coils – One long wire formed into rows
🔹 Pocket Springs – Individual springs wrapped in fabric
🔹 Micro / Mini / Nano Coils – Smaller coils layered for extra comfort
🔹 Steel Frames – Used to hold everything together
At our Calen facility, all steel is removed, compacted, and sent to respective recyclers, giving it a second life instead of sending it to landfill. ♻️
