Pre-Cut Foam Sheets - Frequently Asked Questions (FAQs)
Which foam is the best for upholstery use?
High-density polyurethane foam is ideal for upholstery due to its firmness, durability, and comfort. For added luxury, some projects combine it with memory foam for improved contouring.
Can I use foam sheets for outdoor seating?
Yes. Reticulated foam and closed-cell foam sheets are moisture-resistant and suitable for outdoor cushions and furniture.
Do you cut foam to custom sizes?
Absolutely. In addition to our range of pre-cut foam sheets, eFoam offers a foam cut to size service that allows you to order custom shapes and dimensions to suit your exact needs.
Do you offer free delivery?
Yes, eFoam provides free UK delivery on all foam sheet orders. It’s fast, reliable, and makes it easy to get the foam you need without extra cost.
What's the difference between open-cell and closed-cell foam?
- Open-cell foam is soft, breathable, and great for cushioning and sound absorption.
- Closed-cell foam is firmer, waterproof, and often used for insulation, packaging, and outdoor use.
How do I cut foam sheets at home?
Use a sharp knife, electric knife, or foam saw on a stable, flat surface for clean, accurate cuts. For thicker or denser foam, an electric knife works best.
How do I attach foam sheets together or to fabric?
Apply a strong spray adhesive or fabric glue to the foam, press the fabric on top, and allow it to dry fully. At eFoam we offer heavy duty spray adhesive to ensure the best possible bond.
Can foam sheets get wet?
It depends on the foam type:
- Closed-cell foam is water-resistant and ideal for damp and wet environments.
- Open-cell foam will absorb water and should be kept dry unless designed for filtration or drainage.
Do foam sheets float in water?
Closed-cell foam sheets float due to their water-repellent structure. Open-cell foam, on the other hand, absorbs water and typically sinks.
How do I assess Foam data sheets?
You can access technical specifications and guidance via the foam data sheets page.
How to Choose the Right Foam Sheet for Your Project
Choosing the right foam can feel a bit overwhelming with so many options available, but don't worry, we're here to help! The best foam for you depends on what you're making, how firm you need it to be, and where it'll be used. Let's break it down:
Choosing by What You're Making
- Upholstery & Cushions: If you're after seating that'll last for years, go with High Density or Reflex foam. Medium density's perfect for things like headboards that don't get sat on much. Got thin seat cushions (under 2-3 inches)? You'll want our Severe Very Firm foam to give proper support.
- Mattresses & Bedding: Reflex foam's brilliant for this, it bounces back beautifully and stays comfortable. For cot mattresses, we've got Cot Safe foam that meets all the nursery safety standards whilst still being lovely and soft.
- Protective Packaging: Need waterproof protection? Our closed-cell polyethylene sheets (EFP30/EFP45) are what you want. Packaging electronics? The anti-static AS22 foam will keep them safe from static damage. For general packaging, our standard packaging foam does the job at a lower cost.
- Soundproofing: Acoustic foam sheets work wonders for cutting down echo and reverb. If you're working on a commercial space with fire safety requirements, Pyrosorb-S Class 0 is your foam. The convoluted (egg-crate) style gives even better sound absorption.
- Aquatic Filtration: For ponds and aquariums, you'll want reticulated filter foam. The PPI rating matters here, go with 10-20 PPI if you're dealing with large debris, or 30-40 PPI when you need really fine filtration.
- Industrial Applications: EPDM rubber foam's great for seals and gaskets. Plastazote LD33 is what the medical and sports industries use. And Ethafoam? That's your go-to for semi-rigid protective packaging.
Firmness Levels Explained
Soft: Our Average Soft and Cot Safe foams, think headboards, costumes, light packaging
Medium: Medium foam and Reflex Medium covers most upholstery jobs, gives moderate support
Firm: High-Firm and Reflex Firm are what you want for seating cushions and sturdy furniture
Very Firm: Severe foam better suited for thin seat cushions and heavy-duty seating
Thickness- How Much Do You Need?
We stock everything from 1/4" (6.3mm) right up to 4" (101.6mm). Generally speaking, thicker foam means more comfort and support. Most seat cushions work best at 2-3 inches thick. Packaging usually only needs 1/2" to 1". Mattresses? You'll want at least 3-4 inches to be comfortable.
Where Will It Be Used?
Indoor Use: Standard polyurethane foam sheets are perfect
Outdoor/Damp Areas: You'll need closed-cell foam (like our EFP30/EFP45, Plastazote, or EPDM) or reticulated foam
Fire Safety Matters: Go for fire-retardant foam or our Pyrosorb Class 0 acoustic foam
Chemical Exposure: EPDM rubber foam handles chemicals better than anything else
What Do People Actually Use Foam Sheets For?
We get asked this a lot! Here are some of the most popular projects our customers tackle:
Home & DIY Projects
Around the house, foam sheets are incredibly versatile. People use them for all sorts of things:
- Bringing tired sofas back to life with new cushion foam
- Making cosy window seats and bench cushions
- Creating padded headboards and wall panels
- Custom pet beds that actually support your dog or cat properly
- Garden furniture cushions (using outdoor-suitable foam, of course!)
- Campervan and caravan seating upgrades
- Boat cushions and marine upholstery
- Costume padding for cosplay and theatre productions
Professional & Commercial Projects
On the commercial side, we supply foam for:
- Restaurant booth seating and bar stools
- Office chairs that need new foam
- Church pew cushions and kneelers
- Theatre and auditorium seating
- Gym mats and exercise equipment padding
- Flight case and equipment case inserts
- Product packaging and shipping protection
- Recording studio acoustic treatment
Looking After Your Foam Sheets
Cleaning: Most polyurethane foam can be spot-cleaned with a bit of mild soap and water, nothing fancy needed. Just let it air dry completely afterwards. Closed-cell foams are even easier; you can just wipe them clean. One thing to avoid though: harsh chemicals. They're not kind to foam and can break it down over time.
Storage: If you're storing foam sheets, keep them flat somewhere cool and dry, away from direct sunlight. UV exposure isn't great for foam, it can cause yellowing and make it deteriorate faster. Also keep them away from heat sources and anything sharp (obviously!).
How Long Will Foam Last? The lifespan of foam depends on the foam type, density, and how frequently it is used. High-density upholstery foam is designed for long-term durability and comfort. Reflex foam is known for its excellent resilience and ability to retain support over extended use. Packaging foam and closed-cell foam are highly durable and can last for many years when stored and used in appropriate conditions.
When Should You Replace It? You'll know it's time when the foam loses its bounce, develops permanent dents that don't come back, starts tearing, or gets crumbly. Pro tip: rotating your cushions regularly helps them last longer.
The Technical Stuff (For Those Who Like Details)
Density Ranges:
Light foam (like our Average Soft): 18-22 kg/m³
Medium: 28-30 kg/m³
Firm (High density): 38-40 kg/m³
Very Firm (Severe): 48-52 kg/m³
Reflex foam: 35-40 kg/m³
What's Compression? This tells you how much force is needed to squash the foam down. Measured in Pascals (Pa) or PSI. Higher numbers mean firmer foam, simple as that.
Fire Ratings: Our standard upholstery foams all meet UK fire safety requirements. Pyrosorb-S goes further with a Class 0 rating for stricter commercial specs. Worth noting: HLB Packaging foam isn't usually fire-retardant (it doesn't need to be for its job).
Temperature Range: Polyurethane foam works happily from -20°C to +70°C. Closed-cell foams can handle even more extreme temperatures.
Need Custom Sizes?
Whilst we've got loads of pre-cut foam sheets ready to go, we know that sometimes you need something specific. That's where our foam cutting service comes in handy. Just tell us what size and shape you need, and we'll cut it precisely for you.
Common custom shapes? We do circles, ovals, tapered wedges, bolster rounds, and pretty much any complex template you can think of. We can cut foam from 6mm right up to 200mm+ thick, depending on which type of foam you're after.
