Engineering &
Technical Capability
How a sketch or a photo becomes a chair that can be made a thousand times, the same way every time.
What We Mean by Engineering
We start from whatever you have.
Many clients come to us without finished drawings. They send a napkin sketch, a reference image, or an old chair with a broken joint. Our drafters turn that into dimensioned drawings, check how it will be built, and flag anything that will not hold up before we cut a single part.
If you already have full CAD drawings, we work from those.
Design Development
Sketch, photo, physical sample or CAD file. We produce detailed technical drawings for your review before anything is built.
Prototype & Approval
We build a physical prototype and send you photos, or the sample itself. Production does not start until you sign it off.
Full In-House Production
Frame, foam, sewing, upholstery and finishing are all done in our Semarang factory, so we can check each stage ourselves.
Est. 2012
300+ people. Frames to finishing, in-house.
Semarang
Weinig and Bacci CNC lines, Japanese sewing machines.

What our team can do.
Frame Engineering
Hardwood, engineered timber and metal frames. Parts are cut on Weinig and Bacci CNC machines and assembled in jigs for consistent dimensions.
Ask us →Foam & Comfort
Foam layers chosen for how the piece will be used, whether dining, lounge or contract. TB-117 compliant fillings for the US market.
Ask us →Upholstery
Covers sewn on Japanese machines and checked against patterns. COM/COL accepted, and we will tell you if a fabric is wrong for the job.
Ask us →CAD & Prototyping
Sketch to 3D model to physical sample. The approved sample becomes the production reference.
Ask us →Quality & Compliance
CPSIA, TSCA Title VI (CARB), TB-117 and US/Canada law labels. SVLK-certified timber. BIFMA and BS EN testing on request.
Ask us →Export & Logistics
Packing to your spec, export documents and container booking. Loaded from our own warehouse in Semarang.
Ask us →How It Works
From brief to delivery.
A typical custom project follows these five stages. We give you a realistic timeline at the brief stage.
Brief
Share your concept in any format. We ask questions, clarify requirements, and confirm scope within one working day.
Day 1 to 3Technical Drawing
Dimensioned drawings and 3D renders produced for your review. We iterate until the design is technically and visually correct.
Day 4 to 10Prototype
A single physical sample is built and photographed. International clients can request the prototype be shipped for hands-on review.
Day 11 to 25Production
Full production run begins once the prototype is approved. Each unit is QC-checked against the approved sample before packing.
Day 26 onwardDelivery
Packed and loaded to your specification: flat-pack, fully assembled, or room-ready. Export documentation handled on request.
Per scheduleQuality Checks
What we check, and when.
01 · Material & Frame
Timber and raw materials are inspected on arrival. Frames are checked for strength, joint stability and dimensions against the approved drawing.
02 · Finishing & Upholstery
Colour and surface texture are compared with the approved finish sample. Stitching is inspected, and every seat is sat in to check tension and comfort.
03 · Pre-shipment
Each unit gets a final inspection and is photographed for our records. Quantities and specs are verified against the PO before packing is checked and sealed.

Frequently Asked
FAQ
Any format works: a photo on your phone, a hand sketch, a CAD file, a PDF drawing, a physical sample, or even a verbal description. We have worked from all of these. The more detail you share, the faster we can come back with a technical assessment.
There is no fixed minimum. For residential clients, we regularly produce single pieces. For commercial and hospitality clients, larger runs are more economical but not required. We will advise on the most cost-effective approach for your volume at the brief stage.
Yes. We accept COM (Customer's Own Material) and COL (Customer's Own Leather). We advise on the quantity required based on your specification and the cut plan. We can also source from our own supplier network if you prefer.
From brief to prototype approval usually takes 3 to 4 weeks. Production lead time depends on volume and complexity, and we will give you a realistic schedule at the brief stage. We do not quote lead times we cannot meet.
Yes. We can handle packing specifications, export documentation, phytosanitary certificates, and container booking for international clients. We work with a network of freight forwarders and can advise on the most efficient shipping method for your order.
