Metal-Free Furniture Connectors
Metal-free connectors made of solid wood – sustainable, natural, and ideal for sensitive applications and eco-conscious furniture designs.
Metal-free connectors enable stable joints without metal
Metal-free connectors offer a unique solution for high-end furniture construction – completely without metal components. The Greenline system provides an innovative connector based on a self-locking conical joint made of untreated hardwood. Designed for beds, cabinets, and furniture based on Feng Shui and Bioline principles, Greenline meets the highest standards of stability, craftsmanship, and indoor climate. The connection is made exclusively with hardwood dowels that engage in keyhole-shaped recesses and self-tighten when hooked in – completely invisible, entirely metal-free, and highly durable.

Metal-free furniture connectors promote a healthy indoor climate and long-term stability
Metal-free furniture connectors like the Greenline system are used where function, natural aesthetics, and design must work as one. The construction completely avoids screws, clamps, or metallic guides – and thus any sources of electromagnetic interference in living and sleeping areas. Instead, the conical geometry of the hardwood dowels ensures a self-locking connection that combines high strength with minimal assembly effort. The joint remains invisible, permanently stable, and is also detachable – ideal for beds, solid wood frames, or untreated furniture in bedrooms or children's rooms.
The tension of the conical dowels creates an automatic form-fit when inserted into the milled openings. The system is low in vibration, free of metal conductivity, and can be integrated into existing furniture concepts – without requiring structural changes.
Connectors without metal – free from interference, ideal for bedrooms
Connectors without metal like Greenline demonstrably prevent the formation and transmission of electromagnetic fields caused by metal components. This is especially important in bedrooms, baby cribs, or furniture for sensitive individuals. The wood connector eliminates such influences entirely – by using only untreated hardwood with no metal elements at all.
The connection uses two to seven conical dowels that precisely fit into milled recesses. The geometry ensures a self-centering, self-locking fit that is immediately load-bearing – no screws, glue, or tools required. This technique is ideal for both solid structures and delicate furniture designs with high aesthetic demands.
Solid wood connectors in the Greenline system – technically precise, visually discreet
Solid wood connectors like those in the Greenline system combine traditional craftsmanship with modern functionality. The hardwood dowels are made from carefully selected, moon-felled timber – durable, dimensionally stable, and long-lasting. The keyhole-shaped recesses on the counterpart accept the conical dowel ends precisely. The connection tightens automatically during insertion, providing high strength – all without visible hardware.
This method is perfect for large furniture that must remain stable for years – such as bed frames, headboard joints, or load-bearing cabinet elements. Thanks to its flexible design, the connectors can be used across varying material thicknesses and component geometries.
Detachable wooden connectors – easy to assemble, long-lasting precision
Detachable connectors like Greenline can be assembled and disassembled quickly and easily. The joint is entirely tool-free: dowels are hooked into the prepared recesses and tighten automatically during insertion. The connector system can be opened and closed repeatedly without losing strength or precision.
This is particularly advantageous for knock-down furniture, moving, or reassembly. Even in commercial furniture production, the Greenline system shines: it is efficient to install, remains form-fitting over time, and requires no additional materials or aids.
Delicate connections for baby and children’s furniture – safe, toxin-free, metal-free
Greenline offers not only solutions for heavy beds and furniture but also suitable variants for highly sensitive applications such as baby and children's furniture. The metal-free conical connectors in small dimensions ensure maximum safety, zero toxins, and a sustainable structure. No screws, sharp edges, or metal parts – only child-friendly furniture that is health-conscious and mechanically stable.
Easy tool-free assembly also allows for quick setup – ideal for modular systems or changing environments. The lasting form-fit ensures stability, even if the furniture is repeatedly disassembled and reassembled.
FAQ – Frequently Asked Questions about Metal-Free Connectors
What are metal-free connectors?
These are joining systems made entirely from hardwood, without screws, nails, or metal parts. They are usually based on clamping or plug-in principles like the Greenline system.
What are the advantages of metal-free furniture connectors?
They eliminate electromagnetic interference, improve room climate, are fully natural, and remain visually hidden – ideal for bedrooms and children's rooms.
How does the Greenline conical connection work?
Conical dowels are hooked into milled keyhole recesses. The geometry creates a self-locking, load-bearing connection when inserted.
Is the connection stable enough for beds and solid wood furniture?
Yes. Greenline is engineered for high loads. The joint is play-free, form-fitting, and low in vibration – even after repeated disassembly.
Is Greenline also available for children's furniture?
Yes. The metal-free Greenline connectors are suitable for children's furniture as well, offering flexibility. The furniture can be assembled and disassembled in no time.
