A few months ago I got a call from a mattress factory owner in Colombia. He said: "I'm paying $12 per foam block. I make 200 mattresses a day. Should I produce my own foam?" I asked him to send me his numbers. When we ran them, he was in for a surprise.
It turned out that 40% of his total mattress cost was foam. And of that 40%, more than half was his supplier's margin. He had been buying from the same source for years and assumed the price was market rate. It wasn't.
Polyurethane foam is the main component of most modern mattresses. It represents between 30% and 50% of total material cost, depending on the type of mattress you make. If you're buying pre-made foam, there is a high probability you're paying a 50-80% markup over the actual production cost. That markup is your supplier's profit — and it could be yours.
Below are the real numbers from three factories that made the switch, and how you can calculate whether producing your own foam makes sense for you.
Polyurethane foam is made by mixing polyol and isocyanate with blowing agents, catalysts, and surfactants. The raw material cost to produce a medium-density foam block (25-30 kg/m³) is approximately $3-5 per cubic meter, depending on your purchase volume and location. That same block, bought pre-cut from a supplier, costs you between $10 and $15.
The difference is your supplier's margin — and it's not small. A typical foam supplier operates with 40-60% margins over production cost. Some hit 80% on specialty densities. That means for every $10,000 you spend on foam, $4,000-6,000 is pure profit for your supplier.
The Colombian factory owner I mentioned was spending $2,400 per day on foam. That's $720,000 per year. At an estimated 55% margin, he was overpaying $396,000 per year. With that money he could have bought a foam machine, paid an operator for three years, and still had money left over.
Infinity Mattress Machinery offers two machines for producing polyurethane foam, each designed for a different production volume. The IF-FF3 Automatic Box Foaming Machine produces individual foam blocks with densities from 8 to 80 kg/m³. The IF-FF4 Horizontal Continuous Foaming Plant produces long foam buns in an uninterrupted process.
The IF-FF3 is the ideal choice for factories producing between 50 and 300 mattresses per day. Its touch screen control system stores up to 10 different formulations and lets you adjust parameters on the fly. You can switch from a low-density foam for comfort layers to a high-density foam for support cores in minutes. Its compact footprint makes it suitable even for factories with limited space.
The IF-FF4 is designed for high-volume factories producing 300 or more mattresses per day. It produces foam continuously, eliminating the downtime between batches. It's suitable for a wide range of applications: furniture, bedding, packaging, automotive, construction, and more. Quality is consistent because mixing and dispensing are automated. Once the line is running, it produces foam without interruption.
Case 1: Factory in Colombia — IF-FF3
Produced 200 mattresses per day. Bought foam at $12 per block. Monthly foam cost: $72,000.
Installed an IF-FF3. Raw material cost per block: $4.50. Monthly cost: $27,000.
Monthly savings: $45,000. The machine paid for itself in 4 months.
"I stopped depending on a supplier that raised prices every six months. Now I control my own production and my quality is more consistent."
Case 2: Factory in Mexico — IF-FF4
Produced 500 mattresses per day. Bought medium-density foam at $10.50 per block. Annual spend: $1,575,000.
Installed an IF-FF4 continuous plant. Cost per block: $3.80. Annual spend: $570,000.
Annual savings: $1,005,000. The machine paid for itself in 6 months.
"The IF-FF4 let us double our production without increasing foam costs. It was the best investment we've ever made."
Case 3: Factory in Peru — IF-FF3 + Foam Cutting
Produced 150 mattresses per day with 8 different foam densities. Had to buy each density from a different supplier.
Installed an IF-FF3 with 10 stored formulations. Also added an IF-FYP6 Carrousel Foam Cutting Machine to slice blocks into sheets automatically.
Combined savings: $38,000/month. Both machines paid off in 7 months.
"The flexibility to switch densities in minutes transformed our production line. We used to wait days for a special foam block. Now we make it in an hour."
The IF-FF3 produces foam in batches — one block at a time — and lets you change formulations quickly. It's ideal if you make different mattress types with different foam densities. You can store up to 10 recipes in its touch screen control system and switch between them in minutes.
The IF-FF4 produces foam continuously, creating long buns that are cut to the desired length. It's designed for factories making large volumes of the same mattress type. Continuous production eliminates the dead time between batches and maximizes output per hour.
Both machines produce foam in the 8-80 kg/m³ density range, covering virtually all mattress manufacturing applications. The choice depends on your volume and product variety.
Below are the machines mentioned in this article, plus a recommended addition to complete your foam production line.
Automatic box foaming machine. Density 8-80 kg/m³. 10 storable formulations. Ideal for 50-300 mattresses/day.

Carrousel foam cutting machine. Cuts multiple blocks at once with automatic digital control. The perfect complement to your foam line.
View IF-FYP6Cost savings are the main reason manufacturers decide to produce their own foam, but it's not the only benefit. Factory owners who have made the switch consistently mention other advantages that are just as important.
Total quality control. When you control the formulation, you control the density, firmness, and consistency of every foam block. You don't depend on your supplier maintaining quality standards. Every batch is exactly as you designed it. This is especially important if you export to markets with specific quality requirements.
Production flexibility. With the IF-FF3, you can change formulations in minutes. If a customer asks for a mattress with a specific foam density, you can produce it the same day. You don't have to wait for your supplier to make it and ship it. This lets you accept custom orders your competitors can't handle.
Supplier independence. Foam suppliers raise prices, have production issues, and delay deliveries. When you produce your own foam, you eliminate that risk. Your production schedule depends on you, not on third parties.
Competitive advantage. Producing your own foam reduces your cost per mattress by 20-40%. That means you can offer more competitive prices or increase your profit margin. Either way, you're in a stronger position than competitors who keep buying pre-made foam.
Producing your own foam requires three things:
1. The right machine. IF-FF3 or IF-FF4 depending on your volume. Both are backed by Infinity with technical support, global spare parts, and CE and ISO9001 certification.
2. Raw materials. Polyol, isocyanate, and additives. Infinity can recommend trusted suppliers in your region. You don't have to search on your own.
3. Basic training. The IF-FF3 and IF-FF4 are designed to be operated by staff with minimal training. Infinity includes training with installation. Most operators are producing commercial-quality foam after 2-3 days of instruction.
If you already have experience in the mattress industry, producing your own foam is not a difficult leap. It's the logical next step to take control of your supply chain and reduce your production costs.
Buying pre-made foam is convenient, but it's expensive. Foam supplier margins are hard to justify when you look at the cold numbers. Producing your own foam with the IF-FF3 or IF-FF4 can reduce your foam cost by 50-70%, with a payback period of 4 to 8 months in most factories.
Beyond cost savings, producing your own foam gives you quality control, formulation flexibility, supplier independence, and a real competitive advantage in the market.
The Colombian factory owner from the beginning of this story installed an IF-FF3 eight months ago. Today he produces 250 mattresses per day, has reduced his foam cost by 58%, and is planning to add an IF-FF4 next year. His only complaint: "I should have done this years ago."
