I started my mattress spring workshop six years ago with a single used spring coiler and a lot of ambition. The coiler could only produce 40 springs per minute, and the assembly was done entirely by hand—three workers threading springs into fabric, aligning them by eye, and gluing each row. The output was low, the quality was inconsistent, and the worker turnover was brutal. Pocket spring mattresses were gaining popularity fast, and we could not keep up with demand.
The turning point came when we replaced our old equipment with two machines from Infinity Mattress Machinery: the IF-P130-1 CNC Automatic Pocket Spring Coiling Machine and the IF-PPA Fully Automatic High Speed Pocket Spring Assembly Machine. Together they transformed our spring production from a labor-heavy bottleneck into a fully automated, high-volume operation.
Pocket spring mattresses are the fastest-growing segment in the mattress industry. Consumers love them for their motion isolation, durability, and targeted support. But producing pocket spring units profitably requires precision coiling and fast, accurate assembly. Our old setup failed on both counts.
Our coiling machine was a basic mechanical unit that produced 40 springs per minute. It had no CNC controls—changing spring dimensions meant swapping mechanical parts, a 45-minute job. The springs it produced varied in height by up to 2mm, which caused problems downstream during assembly and gluing.
The assembly process was worse. Three workers sat at a table, manually inserting coiled springs into pre-sewn pockets. They aligned each spring by feel, then applied glue to seal the pocket fabric. A skilled team of three could assemble about 80 mattress spring units per shift—if everything went smoothly. Defects from misaligned springs and uneven gluing ran at 6-8%. We were reworking one out of every fourteen spring units.
The economics did not work. Labor costs consumed 35% of our spring unit selling price. And we could not scale—adding more workers meant more training time, more quality issues, and more supervision. We needed machines that could do the work of six people with higher precision and zero fatigue.
The IF-P130-1 CNC Automatic Pocket Spring Coiling Machine was our first purchase. When I saw the specifications—fully CNC controlled, programmable spring dimensions, 80+ springs per minute—I knew it was the right upgrade. But the real difference showed up on the factory floor.
The IF-P130-1 alone solved our spring quality problem. But springs are only half the equation—they still needed to be assembled into pocket spring units. That is where the IF-PPA came in.
The IF-PPA Fully Automatic High Speed Pocket Spring Assembly Machine was the second piece of the puzzle. While the IF-P130-1 produced the individual springs, the IF-PPA took those springs and assembled them into complete pocket spring units automatically.
Running the IF-P130-1 and IF-PPA together, our pocket spring output jumped from 80 units per shift (with three assembly workers and one coiler operator) to 280 units per shift (with one operator overseeing both machines). The labor savings were immediate and dramatic.
The monthly labor savings of $3,600 plus the electrical savings of $180 gave us a combined monthly cost reduction of $3,780. The combined purchase price of the IF-P130-1 and IF-PPA was approximately $41,000 delivered. That gives a payback period of just under 11 months from cost savings alone—without even counting the revenue from tripled production capacity.
And the additional capacity was enormous. We went from producing 80 spring units per shift to 280. That means a single 8-hour shift now outproduces what used to take three and a half shifts. We dropped from two shifts to one shift and still have 40% spare capacity for future growth.
One of the things I worried about most was whether the IF-P130-1 and IF-PPA would work together smoothly. In my mind, I pictured two separate machines that would need constant coordination and adjustment. The reality was much better.
Infinity's installation team set up both machines in two days. The IF-P130-1 was positioned first, with its output chute feeding directly into the IF-PPA's spring input hopper. A simple conveyor belt carries the coiled springs from the coiler to the assembly machine. The entire workflow is continuous—wire goes in at one end, finished pocket spring units come out the other end.
The operator control panel shows real-time production data from both machines: springs coiled, units assembled, production rate, and any error codes. One operator can manage both machines simultaneously. The training took three days—two for the IF-P130-1 and one for the IF-PPA.
Within the first week, we were running at 70% of rated capacity. By week three, we hit 95%. The transition was smoother than any equipment upgrade I have been through in 15 years in this business.
The quality improvement from the IF-P130-1 and IF-PPA was visible from day one. Our old manually assembled spring units often had visible inconsistencies—springs sitting at slight angles, uneven pocket alignment, and glue marks on the fabric. The automatically assembled units were uniformly perfect.
Our biggest customer—a mattress OEM that buys about 40% of our spring production—noticed the improvement before we even mentioned the new equipment. Their incoming quality inspection showed a defect rate drop from 5.2% to 0.4% on our spring units. They actually called us to ask what we had changed.
The consistent spring height (within 0.3mm) meant that mattress assemblers no longer had to struggle with uneven spring units. Mattress flatness improved, gluing became more consistent, and the final product had a more professional feel. Our customers reported fewer returns and warranty claims related to spring issues.
The multi-zone capability of the IF-PPA also opened up a new market for us. We can now produce three-zone and five-zone pocket spring units that command a 25-30% premium over standard units. This alone has added about $4,000 per month in additional revenue.
Both machines have been running for 10 months, two shifts per day, five days per week. Here is our actual maintenance experience:
If you are producing pocket springs or considering starting, here is what I learned that might help you:
Ten months after installation, the IF-P130-1 and IF-PPA have produced over 1.6 million springs and 56,000 completed pocket spring units. The machines have run for more than 3,800 production hours combined. Total maintenance cost: under $200.
Our monthly labor cost for spring production dropped from $5,400 to $1,800. Our output tripled from 80 to 280 units per shift. Our defect rate fell from 6-8% to under 0.8%. Our biggest customer noticed the quality improvement without being told.
The machines paid for themselves in under 11 months. And the additional revenue from multi-zone premium units is pure profit on top of that. The return on this investment has been the best I have ever made in my workshop.
Looking back, my only regret is not making the upgrade sooner. I wasted two years fighting with old equipment that could never match the quality and output of modern CNC-controlled machines.
If your pocket spring production still relies on manual assembly or outdated coiling equipment, you are leaving money on the table. The IF-P130-1 and IF-PPA are not just incremental improvements—they are a fundamentally different way of producing mattress springs. One that replaces manual labor with CNC precision, replaces inconsistent quality with first-pass perfection, and replaces production limits with scalable capacity.
