How to measure foam for cushions
Follow our simple step-by-step guide to accurately measure foam cushions:
For precise measurements, we recommend measuring your existing covers rather than the foam, as foam can lose shape over time.
Measure your covers from corner to corner along the seams, ensuring they are pulled taut for a good fit. Measure both the front and back of each cover, as cushion widths can vary.
When measuring the depth of a cushion, measure from seam to seam. If your cover has a piped edge, measure between the piping. Order foam to the size of the cover border width and then add Dacron and stockinette for the best fit.
Avoid measuring across the middle of a cushion, as this can be inaccurate due to any domed tops that the cushion may have.
Choose the appropriate product shape from our list and enter your dimensions according to the measuring process described above.
Please Note: If your cushion has significant loft over the seams, you may need to add additional depth for a fuller fit. While Dacron can add loft to your cushion (approximately 1cm top and 1cm bottom), it may not be enough if the depth rises past the seams. If your current cushion has a domed shape, please contact us to discuss your requirements, as it may not be suitable for the Sofa Cushion Foam templates we offer.
What is dacron and stockinette ?
Stockinette is a stretchable fabric tube that can be easily slipped over the foam cushion. It provides a smooth surface for the cushion cover to slide on, making the installation process much easier. This is especially helpful when dealing with snug-fitting cushion covers or foam inserts. Protection for the Foam: Stockinette acts as a protective layer for the foam cushion. It helps to prevent friction between the foam and the cushion cover, reducing the risk of the foam getting damaged or worn out over time. This added protection can extend the lifespan of your foam cushion. Smoother Appearance: The use of stockinette can create a neater and more uniform look for your cushion. It helps to smooth out any imperfections or irregularities in the foam, providing a consistent surface for the cushion cover. This results in a more professional and polished appearance.
Dacron is a polyester fibre fill material that adds an extra layer of softness and plushness to your cushion. It creates a luxurious and comfortable feel when sitting or lounging on the cushion, enhancing the overall comfort of your furniture. Smoother Appearance: Dacron helps to fill out the cushion cover and create a smooth and visually appealing appearance. It can prevent the cushion cover from looking wrinkled or uneven, giving your cushions a more polished and professional look. Improved Loft and Resilience: Dacron can help restore or enhance the loft of your cushion. It adds volume and bounce to the cushion, making it more resilient and preventing it from flattening or sagging over time. This helps to maintain a plump and inviting appearance for your cushions.
Adding both Dacron and stockinette is easy when ordering replacement sofa foam cushions from Right Foam. Simply follow the five steps.
What Type of Foam Should You Use for Your Sofa Cushions?
Foam is a personal preference, just like the famous fairy tale with the 3 bears, it can be too soft, too firm or just Right Foam!
For cushions that are medium we recommend:
For cushions that you would like to be similar to pub seating we recommend a depth of 50mm, 25mm chip foam and 25mm blue foam
For a softer cushion we recommend RF28G or RF100S If you would like to 'try before you buy' We offer a sample service, this is a flat fee of £4.00 which is refunded on all orders over £50

What Type of Foam Should You Use for Your Sofa Cushions?
Polyurethane foam is the best option for sofa cushions, but it's important to choose the right type based on your specific needs. Consider cushion thickness and whether it's a back or seat cushion.
Cushions with 1" to 4" (2.5cm to 10cm) thickness: 39H foam is the perfect choice for thinner cushions. This firm foam provides the necessary support and shape retention with just the right amount of give.
Cushions over 4" (10cm) thickness: 41M foam is a medium-firm polyurethane foam that works great for replacing sagging fiber and foam cushions. If your cushions are over 10cm thick, this foam will offer ultimate comfort and long-lasting shape retention.
Sofa back cushions: 39S foam is a soft, luxurious polyurethane foam that's ideal for sofa back cushions. However, it's not recommended for seat cushions as it's too soft.
Is your foam fire retardant ?
All of our furniture foam complies to The Furniture and Furnishings (Fire) (Safety) Regulations 1988 (as amended)
Does your foam change colour?
Foam is typically made from polyurethane, which can undergo oxidation when exposed to air and sunlight. Oxidation can cause the foam to change color, often turning it yellow or brownish. This process is similar to how other materials, like plastics or rubber, can discolor with age and exposure to the environment. UV Exposure: Exposure to ultraviolet (UV) radiation from sunlight can accelerate the discoloration of foam. UV rays can break down the chemical bonds in the foam, causing it to degrade and change color. This effect is particularly noticeable in foams that are not protected by a fabric cover or are directly exposed to sunlight. Chemical Reactions: Certain chemicals, substances, or environmental factors can react with the foam and cause discoloration. For example, exposure to cleaning agents, body oils, sweat, or other substances can lead to color changes in the foam over time. Age and Wear: With age and use, foam can undergo physical changes that may contribute to color alteration. Continuous compression, moisture absorption, and exposure to contaminants can all affect the appearance of the foam. As the foam wears down or deteriorates, it may lose its original colour and develop a different hue.
What is Stockinette wrap?
Stockinette is a stretchable fabric tube that can be easily slipped over the foam cushion. It provides a smooth surface for the cushion cover to slide on, making the installation process much easier. This is especially helpful when dealing with snug-fitting cushion covers or foam inserts.
Will my foam stay the same or does it soften over time?
Yes, foam can soften over time with regular use. This is a natural process known as "foam fatigue" or "foam compression." The extent and rate at which foam softens can depend on various factors, including the density of the foam, the quality of the foam material, the weight and frequency of use, and the conditions under which it is used.
Foam is made up of tiny cells that contain air or gas. Over time, with repeated compression and pressure, these cells can break down or become less resilient. As a result, the foam may lose some of its original firmness and supportiveness, leading to a softer feel.
The rate at which foam softens can vary. Higher density foams, such as those with a higher weight per cubic foot, are generally more durable and resistant to softening. Lower density foams, on the other hand, may soften more quickly.
Additionally, external factors such as body weight, frequency of use, and exposure to heat and moisture can affect how quickly foam softens. Heavier individuals or those who frequently use the foam cushion may experience more significant softening over time.
It's important to note that while foam may soften with use, it doesn't necessarily mean it needs immediate replacement. Some softening can be expected and may even be desirable for comfort. However, if the foam becomes excessively soft, loses its shape, or no longer provides adequate support, it may be time to consider replacing it.
Regular maintenance, such as rotating or flipping cushions, can help distribute the wear more evenly and prolong the lifespan of the foam. Additionally, using a protective cover or cushioning materials like Dacron can provide an extra layer of protection and help maintain the foam's original firmness for a longer period.
Why does my foam have an odour?
Foam is made from chemicals and as such it can have a odour, this will fade over time and has no impact on the quality or longevity. To help reduce the smell leave in a well ventilated area or alternatively you can use a odour reducing spray to help somewhat.
Rest assured the smell is only ever from new foam as it is against our policy to sell second hand foam.
Can some foam be used outside?
Yes, we can provide waterproof foam, depending on the use there are a couple of options.
For upholstery foam we have our 'outdoor- yellow' This is similiar to sun lounger foam. It can be tight on the pocket however; you can use our blue upholstery foam being sure to use waterproof covers and by taking in when the weather turns.
What is meant by foam DENSITY?
This is in relation to the weight per meter third.
The denser the foam the heavier it weighs, this does not mean that it is firm, in fact depending on the foam type it can be softer or harder. If you are unsure, it is always best to contact us.
