Can a Customized Garden Sofa Frame Keep Its 150 kg Seat Load Rating?

Customizing an outdoor sofa frame is possible, but a revised design should not automatically be assumed to carry the same tested load as the standard product. For the Tango KD Structure Outdoor Sofa Set, the published load capacity is 150 kg per seat. That value should be treated as applicable to the original listed configuration unless the supplier confirms that the customized version has been evaluated accordingly.

What Can Be Customized on a Garden Sofa?

Kingwell offers OEM and ODM development for outdoor furniture, allowing buyers to adjust product dimensions, colors, materials, and selected construction details. Support may include CAD drawings and 3D design services, helping project purchasers define a sofa suitable for hospitality, residential, or commercial outdoor spaces.

However, not all modifications have the same effect on structural performance. A color change may have little relevance to load capacity, while adjustments to frame size, aluminum profile, connection points, welding details, leg placement, or knock-down fittings can change how weight is distributed through the sofa.

Why the Standard Load Rating May Not Transfer to a New Frame Design

The Tango sofa is described as having an aluminum frame, rope-woven elements, a wood-grain finish, and a knock-down structure. Its listed capacity is 150 kg per seat. The available product information does not identify the precise test method, the full frame specification used during testing, or whether the rating remains valid after structural customization.

As a result, the 150 kg figure should not be applied by default to a sofa with modified dimensions, materials, joints, or other frame components. Inspection of a custom product is valuable, but routine production checks alone do not necessarily prove that a revised design meets a specific per-seat load requirement.

What to Confirm Before Approving a Custom Order

Submit Complete Frame Requirements

Provide clear details of every requested change, especially those involving the aluminum structure, tube thickness, overall seat dimensions, support layout, connecting hardware, and assembly method. CAD drawings or 3D renderings can help ensure that the requested specification is accurately understood before production begins.

Request Written Capacity Confirmation

Ask Kingwell whether the proposed configuration is approved for the required per-seat load capacity. The confirmation should state whether the standard 150 kg rating applies to the custom version or whether a different rating is appropriate.

Ask for Available Verification Documents

Before placing production approval, request details of the assessment or testing available for the customized frame. This may include load-test documentation, engineering confirmation, or other records relevant to the final design. It is important to clarify whether testing applies to the exact custom configuration rather than a similar standard model.

Standard Product Data and Custom-Order Questions

Quality Control, Certifications, and Project Use

Kingwell states that it performs quality checks throughout material receipt, production, and final inspection. For the Tango product, the described controls include dimensional review, appearance inspection, structural-stability checks, quantity verification, and packaging inspection. These procedures support production quality, but the available information does not state that every customized sofa frame receives a load test.

The company lists BS 5852 for outdoor furniture and EN 581 for outdoor tables among its certifications. These certifications should not be interpreted as evidence that every altered Tango sofa frame has been tested to preserve the standard 150 kg per-seat capacity. Kingwell also supplies furniture for settings such as hotel and resort terraces, restaurant outdoor dining areas, and villa terraces. Referenced projects, including a large resort sun-lounger order and a hotel terrace order for 80 single sofas, demonstrate project-use experience but do not provide proof of load testing for a particular custom frame.

Frequently Asked Questions

Will the 150 kg per-seat capacity remain valid after changing the frame?

Not automatically. The available product data does not confirm that the stated rating applies after structural modifications. Obtain written confirmation for the exact custom design.

Can the sofa size and material be changed?

Yes. Kingwell indicates that size, color, materials, and product details can be customized through its OEM and ODM services. Any material or structural change should be reviewed for its potential impact on capacity.

What should a buyer request before production starts?

Send the final frame specification and request confirmation of the applicable load capacity, together with any relevant verification, engineering assessment, or test documentation for that configuration.

Conclusion

A garden sofa frame can be tailored to project requirements, but customization and load-capacity validation are separate matters. The Tango KD Structure Outdoor Sofa Set is listed at 150 kg per seat in its stated configuration. Until Kingwell verifies otherwise, that rating should not be assumed for a modified frame. For custom technical confirmation, buyers should submit complete design requirements and contact info@kingwellgrou.com before approving mass production.
