Introduction to Light Vehicle Seating Modifications
Light vehicle seating changes encompass a range of modifications including seat layout alterations, seat removal, and seating reduction for commercial or personal use. Whether you need to convert a passenger vehicle for cargo use, install specialist seating for accessibility, or reconfigure your interior layout, our LK1-certified services ensure every modification is carried out safely and in full compliance with Australian Design Rules.
Operating from our workshop in the Glass House Mountains, we provide professional seating modification services. If you also need child anchor points installed in conjunction with your seating changes, we handle both under one mod plate.

Our LK1 Seating Changes & Reduction Services
Our LK1 services cover a broad scope of seating modifications, including seat layout changes, seat removal for cargo conversion, installation of child anchor points in conjunction with new seating arrangements, and fitting of roll-bars or roll-cages where additional occupant protection is required. We also handle seatbelt installations and adjustments to ensure every seating position is properly restrained.
Whether you are reducing seating capacity for a commercial fitout or adding seats to a vehicle, we manage the full process from initial assessment through to certification.
Why Choose Us for Seating Changes
Enhanced Comfort
Seating modifications can dramatically improve driver and passenger comfort, particularly for vehicles used in specialist roles or for long-distance travel. We tailor each installation to your requirements, ensuring ergonomic positioning and secure mounting for every seat fitted.
Improved Safety Standards
Every seating change we carry out prioritises occupant safety. We use compliant seating and anchorage systems that meet or exceed the relevant Australian Design Rules, ensuring seatbelts and restraint systems function correctly with the modified seat layout. Proper installation reduces the risk of injury in the event of a collision.
Compliance with Australian Design Rules
All LK1 seating modifications must comply with the applicable Australian Design Rules (ADRs). Our approved person ensures every modification meets these requirements and issues the necessary certification documentation. This means your vehicle will pass registration inspections and remain fully road-legal after the seating changes are completed.
Understanding the Certification Process
Fitting Complying Seating to Complying Anchorages
When fitting new or replacement seats, it is essential that the seating meets the relevant ADR requirements and is secured to anchorage points that are engineered to handle crash forces. Our approved person verifies the compatibility of seating and anchorages before installation and ensures all mounting hardware meets the required specifications.
Fitting Complying Seatbelts to Complying Anchorages
Seatbelts must be matched to the correct anchorage points and seating positions. We install ADR-compliant seatbelts that are compatible with the modified seating arrangement, ensuring every occupant position is equipped with a properly functioning restraint system.
ADR Compliance
Full ADR compliance is mandatory for all seating modifications on registered vehicles. Our certification process includes a detailed inspection of the completed work, verification of component compliance, and issuance of the relevant modification documentation. This ensures your vehicle meets all legal requirements for registration and roadworthiness in Queensland.
Key Benefits of Seating Reduction Services
Seating reduction is a popular modification for tradspeople, courier operators, and business owners who need additional cargo space within their vehicle. By removing rear seats and certifying the modification, you gain a larger, flat load area without compromising the structural integrity of the vehicle.
Seating reduction also allows for custom interior fitouts, including shelving, tool storage, and specialist equipment mounting. Combined with proper certification, these modifications transform a standard passenger vehicle into a purpose-built work vehicle that remains fully compliant with Queensland transport regulations. If your seating modification involves child restraint anchor points, our child restraint fitting guide provides essential information on Australian child seat laws and anchor point requirements.
