Seat Foam - Custom Foam Seating

Seat foam can come in all shapes and sizes, from regular squares, rectangles and circles to much more elaborate designs. One of the most popular uses worldwide for polyurethane foam is to create foam cushions and seat pads.

We can cut upholstery foam to practically any size or shape you need. Whether you’re looking to upgrade your sofa cushions, need seating foam pads for window cushions, dining chairs or something completely different, we can help! Ordering online is simple and we even offer a next working day delivery service, meaning your new seat foam could be with you in 24 hours (sometimes even less).

Seating Foam

Seating Foam Cut to Size

Foam seating pads vary in size so often that it’s hard to ever find a finished product that is perfect for your requirements. It’s much simpler to order a custom piece of seat foam made to the measurements you provide.

As the UK’s leading professional foam converter online, we create custom seat pads every single day in a wide range of shapes and sizes. We’ve made it our mission to make ordering foam cut to size online as simple as possible. With GB Foam Direct, all it takes is 5 simple steps.

Ordering Your Foam Seat Pads Online

To order seating foam online you need to start by choosing from our selection of foam templates. We have included a number of popular seat foam shapes on this page but you can find more (25 in total) on our homepage.

If you can’t find the shape you need, you can choose our Custom Foam Shape. This is a special bespoke shape that will allow you to upload a digital template or post a physical one to us. To use this template, you need to input the largest value of your shape for each given dimension.

Once you’ve chosen the correct shape, input your required measurements in cm, mm or inches. If you’re having trouble measuring you can always refer to our dedicated cushion measuring guide or contact our team for advice.

Choosing Your Foam & Extras

Next, you’ll be able to choose which type of foam you would like your seat cushion to be made from. We have a wide variety of high-quality foams to choose from including a number of fantastic seating foam grades. If you’re unsure about which foam is right for you, be sure to pay attention to the information provided on this step or once again contact our team of foam experts for advice.

The next step will ask you if you would like to include Dacron & stockinette with your order. For a small fee, we can include and fit these extras onto your foam seat pad. If you’re unsure what Dacron and stockinette or whether they’re right for you, please refer to our Dacron & stockinette guide. To summarise, Dacron is a polyester wadding that is attached to the tom and bottom of cushions to add loft. Stockinette is a fine netting that covers cushions. It reduces friction making it easier to insert and remove seating foam from a cushion cover.

Seating Foam – Final Steps

Now all that’s left is to finalise your order details. If you have any questions about your order we recommend speaking with our team before finishing. We have a live chat feature towards the end of the ordering process which is monitored throughout our business hours. Don’t forget, we’re the only UK foam supplier online to offer a guaranteed next working day delivery service.

Place your order before 11:00 am Monday – Thursday to qualify. And if the next day doesn’t suit you, you can always choose a delivery date that does. Our courier service will even provide you with a 1-hour expected delivery timeslot on the day your order is scheduled to arrive.

Seat Foam FAQs

To help you find the perfect seat foam for your next project, we’ve put together this handy guide answering numerous frequently asked questions. Of course, if you can’t find the answer that you need here, you can always contact our experts for advice.

How Thick Should Foam Seating Be?

Seating foam thickness can vary quite substantially. Some thinner foam seat pads can be approximately 1 inch thick, whereas thicker seat cushions can exceed 4 inches. At GB Foam Direct, you can order seat cushion foam to the thickness you require. Just be sure to choose a suitable foam in relation to the thickness you order.

What Foam is Used for Seats?

Depending on the required measurements and application the type of seat foam you’ll want to use will differ. For example, seat cushions used for commercial grade furniture are often made using a heavy-duty reconstituted foam. For quality seat cushions between 1 and 4 inches thick, you could opt for a firm feeling foam such as our Luxury Firm Sofa Foam. Over 4 inches a medium such as our Luxury Medium Sofa Foam may suit you better.

What Density Foam is Best for Seat Cushions?

High density foam is generally best for seat cushions. A high density foam will last longer than one with a low density. Here at GB Foam Direct, we stock a wide range of high density foams which you can order cut to the size and shape you need.

Is Memory Foam Good for Seat Cushions?

On its own, memory foam does not usually make a very good seat cushion as it is a soft foam that will likely not offer enough support. However, you could choose to top a firmer base layer of foam with a layer of memory foam for additional levels of comfort. We can bond multiple layers of foam together for you. Just leave clear instructions at the checkout to do so if you would like us to do this for you.
