The comfort and longevity of your sofa can be greatly impacted by selecting the appropriate foam rubber. Different types of foam rubber, which is classified based on density, are commonly referred to as cushioning or foam. Density is important because it affects the cushion’s feel, firmness, and durability over time.
Foam with a higher density is better for seats and high-traffic areas because it is generally more resilient and supportive. Although initially softer and more comfortable, lower density foam may compress more quickly with repeated use. Choosing the appropriate type according to your preferences and usage patterns is made easier by being aware of these distinctions.
Think about the design of the sofa, how you use it, and your comfort preferences when deciding whether to replace the foam rubber on your sofa. Your sofa will last longer and provide better support and comfort if the foam rubber is replaced. Your sofa will feel perfect and hold its shape over time if the measurements are taken correctly and the density is selected.

Types by density
The longer the service life, the higher its density. You can navigate the different types of foam rubber by using the letter indicators that are displayed on the label. The first digit of a digital value represents a density indicator, and the ones that follow represent compression stress indicators.
Soft
Foam rubber can be used to outfit bedrooms (sofas, beds, couches). It has a density of roughly 25 to 45 kg per cubic meter. Good softness, elasticity, and firmness indicators make sleeping more comfortable. With a sofa like this, you can unwind in your bed without experiencing any discomfort from prolonged sitting or standing.
HS symbols are used to mark soft materials. The packaging has this marking attached to it.
Although the product feels very nice to the touch, it is not very sturdy. The canvas needs to be fixed or changed entirely on a regular basis.
Standard
Produced using a base polyol. To achieve the necessary strength, density, and elasticity, it might contain extra ingredients. This kind of foam rubber is typically used to finish headrests and armrests on upholstered furniture. Density: 25 to 30 kg per cubic meter.
You should look for the ST marking on the label and pay attention to the numerical values in order to select a standard foam rubber. They are meant to display the density and compression stress to the customer.
The most widely available version on the market, the standard version is useful for self-assembly and restoration. The sole and major drawback of foam rubber is its low strength, which makes it incapable of supporting large weights. It cannot be used with heavier loads—more than 90 kg will not be tolerated.
Hard
Not appropriate to put on children’s mattresses. This is not a very pleasant way to unwind. However, those who favor hard surfaces over soft ones will find it ideal. Density: 25–40 kg per cubic meter. HL sign for marking.
Ideal for couches that people sleep on all the time. Instead of using it as a place for everyone to rest, it is preferable to sleep on it.
Increased rigidity
The product is more rigid thanks to special polyols. They repeatedly gain strength, but the components that make up this indicator vary. Density: 30 kg per cubic meter. A great material for covering couches and mattresses. Furniture that has a higher density value can support heavier loads. EL is the marking.
No upper weight limit. This is a cozy choice for a restful night’s sleep. The surface will get softer and more comfortable for sleeping in any position if you add another layer of comfort-enhancing foam rubber on top.
Highly elastic
Withstands weight of up to 100 kg and has a density of more than 30 kg per 1 m 3. It is mostly utilized to make premium mattresses. The material’s initial rigidity and load-bearing capacity are astounding. The HR symbol on the packaging indicates high elasticity.
Exclusive choice at a high cost. These models, which are the best canvases available, are used to produce opulent furniture.
Highly elastic with increased comfort
Density-wise, foam rubber used to make comfortable furniture ranges from 30 to 55 kg per cubic meter. The material is soft. On it, you can unwind, slumber, and sit with comfort. You must locate a label with the HR marking with an asterisk on it in order to choose a highly elastic product with greater comfort.
One of the best materials is foam rubber, which is more elastic and more comfortable. It is picked for opulent settings where other choices would just not complement the opulence and wealth of the setting. Such bedding is just beyond earthly comfort. The same holds true for quality.
With these qualities, foam rubber can withstand even the hardest loads, is always up to par, and can be used continuously.
How to replace it yourself: instructions
Tools and materials to change
You will need the following tools to replace the foam rubber in the sofa:
- set of wrenches;
- scissors for cutting material;
- side cutters, nippers;
- construction stapler;
- sewing machine;
- strong threads;
- accessories for decorating pillows (buttons, appliques).
Tapestries are the best material. It blends well with other textiles and fabrics in the room and has a great appearance. is able to be cleaned without compromising its appearance with any detergent.
The following are the most popular choices for upholstery in homes:
On the sofa, any kind of fabric looks extremely elegant—even elegant.
If foam rubber is selected, faux leather will not function. This is because it is best to leave the work to the experts; it is hard to tighten it evenly on your own.
This article explains how to cover a sofa yourself and what kind of material is ideal for upholstery.
Laying order: how to lay?
Phases of the project:
- All pillows, blankets, decor are removed from the sofa. Then they begin to inspect the casing. It is necessary to turn the sofa so that it is convenient to inspect the frame. It is important to identify all wooden parts for fractures and rot.
- If upholstery replacement is needed, it is performed immediately after inspection. To do this, take fabric identical to the old coating. The frame is replaced by using special plywood and screws that will be suitable for working with the material.
- Carefully check the areas under the pillows. If the platform between them is broken, then make a support.
A special ready-made support (usually made of fiberboard or higher quality materials, depending on the manufacturer) can be purchased in construction stores.
How to fix it?
You can obtain the previous filler and apply it to the new pattern. You must carefully measure and cut each component on the pattern before attaching the layer.
The upholstery ought to be beautifully and snugly positioned. In order to accomplish this, firmly press it into the foam rubber where the upholstery is fastened to the base. In this instance, it will add elasticity and help straighten the material.
The construction stapler should stretch the fabric tightly. The bottom of the details that are available should have brackets. The joints and fit of the individual parts cannot be reached; you risk hooking the upholstery and damaging the exterior finish. The fabric must be pulled taut, then secured with a construction stapler.
The parts’ bottoms should be where the brackets are placed. It is imperative that the joints and adjacent parts do not overlap in order to safeguard the upholstery and prevent the sofa from folding completely in the desired direction.
Assembly
Reassemble in the opposite order. Everything is in its proper place. To correctly reassemble everything, you must keep in mind the steps involved in disassembly. The procedure can be captured on camera.
Each part’s wooden base should be able to accommodate the cut filler snugly. At this point, the thicker layer of filler allows you to add volume to the armrests and back. You will need to stretch and distribute the fabric along the edges more when the fabric is larger in size.
The main middle part is assembled differently than the sides and back. Here softer foam would be more appropriate. These projecting parts don’t have to bear a heavy load and are easily removed without needing more care. A layer of firmly fixed fabric is placed on top of any spring blocks that may be present at the base (what to do if the spring block breaks?).
Having canvas on hand will help ensure that the task is completed effectively. You can use any other cloth that is comparable. Each component needs to be covered. After that, the bed or sofa is put back together to its original state prior to disassembly.
For comfort and longevity, selecting the appropriate foam density for your sofa cushions is essential. The amount of foam material packed into a specific volume is known as foam density, and it is typically expressed in pounds per cubic foot (lb/ft3). Greater density foams are perfect for sofas that are used frequently because they last longer and offer better support. Softer and less expensive, lower density foams have the potential to compress more quickly over time.
Think about how you will use the foam when choosing it for your sofa. Choose a higher density foam that can tolerate regular wear and tear if your home is busy and has children or pets. A medium density foam could be adequate for infrequent use in a formal living area or guest room, striking a balance between durability and comfort. The feel of a sofa can also be influenced by its density; softer foams give a plush, sink-in feeling, while firmer foams offer more support.
A practical way to prolong the life of your furniture and improve its comfort is to replace the foam on your sofa. Sagging cushions, a loss of form, or discomfort when sitting are indications that the foam in your sofa needs to be replaced. Make sure you order the right size and foam density by taking accurate measurements of your cushions. The majority of suppliers provide custom cutting to match the exact dimensions of your sofa.
New foam installation is typically doable at home with simple tools. With caution, remove the old foam and any batting or covering made of fabric. Make sure the new foam fits snugly inside the cushion covers. If more batting is needed, add more layers to give it more softness or to even out any uneven areas. Lastly, firmly replace the cloth covering. Replacing your sofa foam can revitalize your furniture and improve your comfort for many years to come with the right upkeep and care.
