We’ve spent years working with these materials. Our recommendations come from hands-on experience, not marketing fluff. By the end, you’ll know exactly which foam solves your problem, whether that’s a comfortable mattress, protective packaging, or sturdy cushions.
7 Different Types of Foam
Here are 7 types of foam that you’re sure to love. Let’s get started:
1. Polyurethane Foam – The Most Versatile Option
Polyurethane foam is everywhere. You’ve probably slept on it or sat on it today without knowing.
The open-cell structure creates tiny air pockets that compress under pressure and bounce back. This gives you that cushiony feel you expect from good foam.
Here’s why it’s popular: You can get it in almost any firmness level. Need soft for a soft pillow? They make it. Want firm enough for heavy seating? They make that too.
Cost is the biggest factor. I’ve worked with dozens of foam types. Polyurethane offers the best value for most jobs. You get solid performance without breaking the bank.
The grade you choose makes a huge difference. Here are the four main options:
Soft Grade (SF21) – Headboards and lightweight applications only. Too soft for seating.
Medium Grade (SF33) – Domestic seating cushions over 5 inches thick. Thinner cushions need firmer foam.
High Firm Grade (SF38) – The workhorse. Sofas, pet beds, and pallet furniture. Most popular grade in the UK for good reason.
Very Firm Grade (SF50) – Tough jobs. Window seats, dining chairs, vehicle restoration, and cushions under 3 inches.
Quick tip: Match the grade to your use. Wrong grade leads to sagging or discomfort. The right grade makes all the difference.
2. Memory Foam – The Body-Contouring Champion
Memory foam remembers your body. It’s the only foam that molds to your exact shape and stays there until you move.
Here’s how it works: The foam has viscoelastic properties that respond to heat and pressure. When your warm body touches it, the foam softens. When you apply pressure, it conforms to every curve. This happens within just a few minutes.
Fun fact: NASA created this technology for astronaut seats in the 1960s. They needed something that could absorb the massive forces during takeoff and landing.
You have three main options to choose from:
Light Density (1.5 lb/ft³) feels the softest. It’s perfect for children and lightweight adults under 150 pounds. But it won’t last as long – expect 3-5 years.
Standard Density (2.5 lb/ft³) gives you the sweet spot. Most people find this density comfortable. It provides good support without being too firm. Lasts 5-7 years with regular use.
Gel-Infused Memory Foam solves the heat problem. Regular memory foam can sleep hot. The gel particles pull heat away from your body for cooler nights.
Here’s where memory foam shines: Mattresses are the obvious choice, but don’t stop there. Pillows and toppers can transform any bed. Medical facilities use memory foam for bedridden patients because it prevents pressure sores.
One warning: Memory foam takes time to respond. If you move around a lot at night, you might find it too slow to adjust.
3. Polyethylene Foam – The Durable Protector
This foam doesn’t mess around. It’s built to protect your most valuable items from damage.
The closed-cell structure makes all the difference. Each tiny cell is sealed off from the others. Water can’t get in. Chemicals can’t penetrate. It’s practically indestructible.
Plus, it’s shatterproof. Drop it, kick it, throw it – polyethylene foam bounces back. The non-abrasive surface won’t scratch delicate items either.
Shock absorption is where it excels. Heavy items that would crush other foams barely dent this stuff.
You’ll find polyethylene foam protecting:
- Electronics during shipping
- Sports gear and water equipment
- Car parts and automotive applications
- Construction projects as insulation
Smart choice for: Anything valuable that needs protection. The upfront cost pays for itself when your expensive equipment arrives intact.
4. Cross-Linked Polyethylene (XLPE) – Premium Performance
This is polyethylene foam’s sophisticated cousin. Everything good about regular polyethylene, but better.
Class A surface protection means you can use it directly on painted surfaces without worry. No scratches, no marks, no damage.
The durability is exceptional. I’ve seen XLPE foam last 10+ years with daily use. The smooth, fine cell structure looks professional even after heavy wear.
Professional applications include:
- Tool cases and equipment storage
- Industrial padding for machinery
- Gym equipment and exercise mats
- High-end packaging for expensive items
The trade-off: You’ll pay more upfront. But if you need foam that performs year after year, XLPE delivers.
Best for: Applications where appearance and longevity matter more than initial cost.
5. Latex Foam – The Natural Alternative
Latex foam comes straight from rubber trees. No synthetic chemicals, no artificial additives.
You have two choices:
Natural Latex is 100% rubber tree sap. It’s processed without harmful chemicals and offers excellent breathability.
Organic Latex takes it further. GOLS certification ensures sustainable sourcing and organic processing. Over 95% organic composition.
The health benefits are real: Natural resistance to dust mites and allergens. No volatile organic compounds (VOCs) that can cause breathing problems. Your air stays cleaner.
The support is different, too. Latex has natural elasticity that responds quickly to movement. It bounces back faster than memory foam but still conforms to your body.
Perfect for: Premium mattresses, eco-friendly furniture, and anyone with chemical sensitivities or allergies.
The downside: Higher cost than synthetic options. But many people find the health benefits worth the investment.
6. Polystyrene (EPS) Foam – The Budget-Friendly Choice
You know this foam. It’s the white stuff that protects your new TV or keeps your takeout food warm.
Lightest weight option available. A sheet of EPS foam weighs almost nothing, which keeps shipping costs low.
Thermal insulation is excellent. That’s why it’s used in building construction and disposable coolers.
But here’s the catch: It’s brittle. Drop something heavy on it and it cracks. It doesn’t absorb vibration well either.
Common uses include:
- Appliance packaging and shipping protection
- Building insulation in walls and roofs
- Disposable food containers
- Basic protective packaging
Choose EPS when: Cost matters more than durability. It’s perfect for one-time use applications.
Avoid it for: Anything that needs to last or absorb repeated impacts.
7. Reconstituted Foam – The Recycled Solution
This foam gets a second life. Manufacturers take foam scraps and bond them together with strong adhesive.
The result is surprisingly good. Dense, resilient structure that often outperforms new foam. Plus, you’re helping the environment by using recycled materials.
The density varies, but most reconstituted foam is quite firm. Perfect for applications that need serious support.
You’ll find it in:
- Wheelchair seats and medical equipment
- Bar stools and commercial seating
- Church furniture and kneelers
- Heavy-duty packaging applications
Why choose reconstituted? Superior support at a lower cost than premium foams. Environmental responsibility is a bonus.
Best applications: Commercial seating, medical equipment, and any situation where firmness and durability matter more than appearance.
The recycled look doesn’t bother most people in these applications.
Conclusion
Choosing the right foam doesn’t have to be complicated. Each of these 7 types serves a specific purpose. Memory foam excels at comfort, polyethylene protects fragile items, and cross-linked options handle heavy-duty jobs.
Your decision comes down to three key factors: what you’re using it for, how long you need it to last, and your budget. Don’t overpay for premium features you won’t use. But don’t go cheap if durability matters.
Start with your specific need. Match it to the foam type that handles that job best. The right choice will serve you well for years.
Still unsure? Go back to the comparison sections above. Focus on the applications that match your situation. The perfect foam solution is waiting – you just need to pick the one that fits.
