At Advanced Upholstery Services, we know that what’s inside your furniture matters just as much as how it looks on the outside. Whether you’re restoring a classic chair, upgrading your sofa, or designing a custom piece, the right foam can completely change how it feels, lasts and performs over time.

That’s why choosing the right foam density is one of the most important decisions you’ll make for your upholstery project. As professional upholsterers and foam cut to size suppliers, we’ve worked with every type of foam out there. Here’s what you need to know to make the best choice for your cushions.

What Does Foam Density Actually Mean?

Foam density refers to the weight of the foam per cubic foot and is measured in kilograms per cubic metre (kg/m³) in the UK. It doesn’t just affect how soft or firm the foam feels—it also tells you how durable and supportive the foam will be over time.

Lower density foams tend to feel softer but will break down quicker, losing their shape and support. Higher density foams feel firmer and are more resistant to wear and tear, making them ideal for everyday use in high-traffic areas.

So, when choosing foam for your cushions, it’s not just about comfort—it’s about choosing something that lasts.

Comfort vs. Longevity: Finding the Balance

It’s easy to pick foam that feels soft and comfortable at first touch. But the real test comes after months—or years—of daily use. Foam that starts out soft may end up sagging or flattening if it’s not dense enough for its purpose.

For seat cushions, we usually recommend a high-density foam with medium to firm support. This gives a good balance of comfort and resilience. For back cushions or scatter cushions, a softer and slightly lower density foam may be more appropriate, since they don’t bear as much weight.

Every project is different, so it’s important to choose foam based on how the furniture will be used. That’s why our foam cut to size and shape service is so popular with both professional upholsterers and DIY customers. It allows you to select the perfect density and shape for each cushion, ensuring maximum comfort and longevity.

Types of Foam: What to Consider

There are several types of foam used in upholstery, each with its own characteristics. Here are a few of the most common:

• High-density polyurethane foam: Excellent for everyday furniture. It provides firm support and holds its shape well over time.

• Reflex foam: Often used in premium furniture. It offers great resilience and comfort, ideal for seating.

• Memory foam: Best for pressure relief and luxurious feel, although it’s often layered on top of a firmer base foam for structure.

• Reticulated foam: An open-cell option that’s perfect for outdoor cushions because it drains water easily and resists mould.

At Advanced Upholstery Services, we stock all of these types and more. Whether you need replacement cushions for a sofa or foam inserts for a custom piece, we can supply exactly what you need.

Why Custom-Cut Foam Matters

Mass-produced foam cushions often come in standard sizes that don’t always fit your furniture properly. That’s where our foam cut to size service comes in. When foam is cut precisely to your measurements, it fills the cushion cover neatly, provides even support and prevents awkward gaps or sagging areas.

Even better, our foam cut to size and shape service allows you to match unusual or curved designs, like window seats, campervan beds or antique furniture. Simply give us your measurements or a paper template, and we’ll take care of the rest.

What to Ask Yourself Before Choosing Foam

Not sure what kind of foam to choose? Here are a few questions that can help guide your decision:

• How often will the cushion be used?
• Is it for sitting, leaning, or just for decoration?

• Will it be exposed to moisture or used outdoors?

• Do you prefer a firm or soft feel?

• What are the exact measurements of your cushion covers?

Once you know the answers, our team can help you choose the best foam type and density for your needs. And with our foam cut to size and shape service, you can rest assured it will fit perfectly.
