Five years ago, we were a small mattress assembly shop in Indonesia — buying pre-assembled spring units, pre-cut foam, and finished quilted panels from a dozen different suppliers. We assembled mattresses, but we did not manufacture them. Every component we touched had a middleman's markup, and every supply chain disruption — which happened three or four times a year — meant delayed orders and unhappy customers.
Two machines changed that trajectory. The IF-Z2-PGY Zig-zag Spring Forming Machine let us diversify into custom spring production for furniture and sofabeds — a new revenue stream that funded the next phase of growth. The IF-APL Mattress Automatic Production Line transformed us from an assembly shop into a full-line mattress manufacturer, capable of producing complete mattresses from raw materials. Here is the story of how we did it — and how the combination of these two machines turned our business around.
Five years ago, our operation in Surabaya was simple: we bought pre-assembled pocket spring units from a supplier in Jakarta, pre-cut foam layers from a foam distributor, quilted panels from a textile workshop, and tape edge from another subcontractor. Our "factory" was really just an assembly line where we put these components together. We employed 12 people and produced about 200 mattresses per month.
The margins were thin — approximately 12% — because every component we purchased included a supplier's markup. The pocket spring units alone cost $28 each, representing 35% of our total material cost. We had no control over quality (spring units arrived with defect rates averaging 5%) and no ability to customize. When a customer asked for a different spring configuration or a special mattress size, we had to decline or charge a premium that made us uncompetitive.
The turning point came when a local furniture manufacturer approached us about producing zig-zag spring units for sofabeds and upholstered furniture. They needed 2,000 units per month — a contract worth $36,000 annually. The problem: we had no way to produce zig-zag springs. This opportunity forced us to think beyond mattress assembly and into component manufacturing.
We invested in the IF-Z2-PGY High Speed Zig-zag Spring Forming Machine specifically to fulfill the furniture contract. The IF-Z2-PGY produces S-shaped (zig-zag) continuous springs at speeds of 300 to 800 pieces per minute — a speed that opened our eyes to what automated spring production could achieve.
The machine is remarkably simple to operate. It takes steel wire as input and outputs finished zig-zag springs through a fully automatic forming process. The spring dimensions — width, pitch, and wire gauge — are set via the control panel, and the machine handles the rest. One operator manages the IF-Z2-PGY while also tending to the spring collection area. The machine runs quietly (a fraction of the noise of our pocket spring assembly area) and includes a special protective device that stops operation if a safety zone is breached.
The IF-Z2-PGY transformed our business in ways we did not anticipate. The furniture contract alone generated $36,000 in annual revenue — and because the raw material (steel wire) cost only $0.18 per unit, our profit margin on zig-zag springs was 68%. This was dramatically better than our 12% mattress assembly margin. Within six months, we had signed three more furniture clients, and the IF-Z2-PGY was running two shifts to keep up with demand. The custom spring business was generating $8,400 per month in profit — enough to fund the next major investment.
The IF-Z2-PGY's flexibility also opened product diversification within our mattress line. We began producing sofabeds and foldable mattress bases, each requiring zig-zag spring supports. These products commanded 25% higher margins than our standard mattresses, and the IF-Z2-PGY made them possible without any additional equipment.
| Speed | 300–800 pieces/min |
| Control | Fully automatic, adjustable dimensions |
| Operation | Simple, low noise, single operator |
| Safety | Protective device with auto-stop |
| Applications | Sofabeds, furniture, mattress bases, upholstery |
With the IF-Z2-PGY generating steady profit, we turned our attention to the goal we had started with: transforming from an assembly shop to a true mattress manufacturer. The IF-APL Mattress Automatic Production Line was the investment that made this transformation possible.
The IF-APL is a fully integrated production line that can produce a complete mattress from raw materials. It combines all the core manufacturing processes — spring unit assembly, foam layering, quilting, tape edging, and packing — into a continuous, automated workflow. For us, it meant bringing the processes that we had been outsourcing (quilting, tape edge, panel cutting) in-house, while integrating them with the spring and foam manufacturing capabilities we had already built.
The IF-APL line occupies approximately 200 m² of our factory floor and is operated by a team of four technicians. It handles the complete mattress production cycle in a continuous flow: raw materials enter at one end, finished mattresses emerge at the other. The line replaced dozens of individual workstations and eliminated the material handling delays that had plagued our assembly-based process.
Installing the IF-APL was the single most transformative decision we made. It reduced our per-mattress manufacturing cost by 60% — from $98 (assembly with outsourced components) to $39 (integrated manufacturing). The line's capacity of 12–15 mattresses per hour meant we could produce more in one shift than we had previously produced in two shifts with our assembly team. And because the line controls every process step, the quality consistency improved dramatically — our defect rate dropped from 7% to under 1.5%.
| Type | Fully integrated automatic production line |
| Output | 12–15 mattresses/hour |
| Labor | 4 operators (vs 12+ in assembly) |
| Floor Space | ~200 m² |
| Processes | Spring assembly, layering, quilting, tape edge, packing |
| Investment | ~$85,000–$120,000 (depending on configuration) |
The IF-APL Mattress Production Line — from raw materials to finished mattresses in a continuous flow.
Here is the combined financial picture after adding both the IF-Z2-PGY and IF-APL to our operation:
| Metric | Before (Assembly) | After (Manufacturing) |
|---|---|---|
| Mattress cost per unit | $98 | $39 |
| Monthly mattress output | 200 | 600 |
| Defect rate | 7% | 1.5% |
| Production staff | 12 | 8 |
| Revenue (mattress + springs) | $24,000/mo | $72,000/mo |
| Gross profit margin | 12% | 38% |
| Product lines | Mattresses only | Mattresses + sofabeds + springs |
The numbers tell a clear story. Our monthly revenue grew from $24,000 to $72,000 — a 3x increase — while our production staff decreased from 12 to 8. The IF-Z2-PGY contributed $8,400/month in profit from custom spring sales, and the IF-APL reduced our mattress manufacturing cost by 60%, adding approximately $35,400 per month in additional margin.
The combined investment — approximately $15,000 for the IF-Z2-PGY and $95,000 for the IF-APL — was recouped in 11 months. After that, the monthly profit improvement of $43,800 became a sustainable, growing income stream that continues to fund further expansion.

Monthly revenue tripled from $24K to $72K. Profit margin tripled from 12% to 38%.
One of the most important lessons from our journey is the value of sequencing investments. We did not buy the IF-APL first, even though it was the ultimate goal. We started with the IF-Z2-PGY because it was a lower-risk entry point that generated its own capital for the larger investment.
This approach worked for three reasons. First, the IF-Z2-PGY cost $15,000 — an amount we could finance from operating cash flow. Second, it produced a product (zig-zag springs) that had immediate demand from local furniture manufacturers, so it generated revenue from day one. Third, the experience we gained running automated production — setting parameters, maintaining equipment, training operators — prepared us for the complexity of the IF-APL line.
For other small manufacturers considering a similar transformation, we recommend the same phased approach: identify one process step where automation can generate quick returns (spring forming, quilting, or foam cutting are good candidates), use that machine to build capital and experience, then invest in full-line integration. The IF-Z2-PGY is an ideal starting machine because of its low cost, simple operation, and immediately accessible market for zig-zag springs in the furniture industry.
✅ You are currently assembling from purchased components: If more than 60% of your mattress cost comes from outsourced components, integrating manufacturing will cut costs by 40–60%.
✅ You have access to local furniture manufacturers: The IF-Z2-PGY's zig-zag springs are in demand by sofabed, sofa, and upholstery manufacturers. A single client relationship can justify the investment.
✅ You want a phased approach to full-line manufacturing: Starting with the IF-Z2-PGY (or a similar component machine) lets you build capital and experience before investing in the full production line.
✅ Your production target exceeds 500 mattresses/month: The IF-APL's capacity is best utilized at volumes above 500 mattresses per month. Below this, a manual assembly line with automated component machines may be more cost-effective.
"I started this business in my garage assembling mattresses from parts I bought from a dozen suppliers. I thought that was what mattress manufacturing meant. It took a chance conversation with a furniture maker to realize we could be making components — not just assembling them. The IF-Z2-PGY was the first machine I bought with my own money. It paid for itself in four months and gave us the confidence to go all-in with the IF-APL line. Today, we make everything — springs, foam layers, finished mattresses — and our profit margin is three times what it was."
— Hendra W., Founder & CEO (14 years in mattress manufacturing)
The combination of the IF-Z2-PGY zig-zag spring former and the IF-APL mattress production line transformed our business from a low-margin assembly shop into a diversified, full-line manufacturer. The IF-Z2-PGY opened a profitable new revenue stream in custom springs, and the IF-APL brought component manufacturing in-house, cutting our mattress costs by 60%.
For small and medium mattress manufacturers, this phased approach — starting with a single machine, generating capital and experience, then investing in full-line integration — is a proven path to growth. The IF-Z2-PGY is the ideal entry point: low cost, immediate market demand for its products, and a 4–6 month payback. Once the spring business is established, the IF-APL completes the transformation, turning an assembly shop into a true manufacturing operation.
Five years ago, we assembled mattresses from other people's components. Today, we manufacture complete mattresses and custom springs under one roof. The IF-Z2-PGY and IF-APL made that possible — and they can do the same for your business.
