Sofa DNA Explained

The quality of a sofa goes beyond its looks. Instead, the sofa's foundation is what truly contributes to its overall class. Different parts of the sofa such as the frame, cushion filling, and seating support, determine not only the comfort level of your sofa, but also its ability to retain its shape in the years to come. 

Here, we share the components of what makes a quality sofa worth investing in. 

Framework

The longevity of a sofa as well as the retainment of its shape is highly dependent on the framework. One common feature that many quality sofas have, whether leather or fabric, is a strong and sturdy frame. 

• Materials

A common material used by many sofa retailers is softwoods. While these sofas are lightweight and affordable, softwoods are considered less durable with a shorter lifespan. On the other hand, luxury furniture retailers in Singapore often choose to use kiln-dried solid wood as frames for their sofas.

Unlike softwoods that are usually derived from pines and cedars, solid woods are known to be more durable and also eco-friendly. 

What sets kiln-dried solid wood apart from the others is that it undergoes a thorough process known as kiln-drying to remove all moisture from the wood. This allows the solid wood frame to retain its shape and stability, while reducing the risks of mould growth. 

• Sturdy joints

The joints of sofas are also another important component for durability. In many designer sofas sold by furniture retailers in Singapore, joints are often glued, dowelled, and nailed together. The corners are also further strengthened with the addition of reinforcing blocks. 

• The use of engineered wood 

Engineered wood is created by binding wood fibres, strands, particles, sawdust, as well as other lumber byproducts together with adhesives under a very high temperature and pressure. This results in a strong bond being formed. Engineered wood is also a common material used for sofa frames due to its versatility; the use of engineered wood makes it easy to work with many different sofa designs and materials such as Chesterfields, modular sofas, etc.

Seating Support 

Another factor to determine the quality and long-term comfort of a sofa is the seating support. As we all know, a sturdy frame provides a good foundation, whereas seating support augments it. 

While the best seating support option found in sofas is the 8-Way Hand-Tied suspension, most sofas use sinuous spring, also known as the no-sag spring. No-sag spring is made up of heavy-gauge steel wires which are bent into a continuous line of vertical S-shaped coils. Horizontal metal tie rods are used to reinforce the coils, preventing shifts and sags. These coils are then secured to the frame using padded clips and fasteners. High-quality sinuous springs that do not sag easily also increase the longevity and durability of sofas. 

Some luxury furniture brands in Singapore like Black & Walnut also use high-tenacity polypropylene webbing to further support the sinuous springs. Not only does web suspension provide additional seating support, it also creates a feel that is similar to that of a hammock, making it comfortable.  

Cushion Filling

Most sofa cushions are made using a combination of fillings such as polyester, feathers, high-density foam, and down. Contrary to popular belief, the firmness of cushions does not have an impact on the longevity and durability of a sofa. Instead, the primary determinant is the density of the foam used. 

The various combinations of fillings cater to the unique needs of each individual. For instance, if you prefer a firmer sofa cushion, you can select high-density foam as it prevents the cushion from sagging. Whereas, if you prefer sinking into your sofa after a long day’s work, then down-filled cushions are ideal for you. Down is considered a premium choice, as they provide users with maximum comfort. High-quality designer sofas such as ones from Black & Walnut often combine down with feathers and high-density foam, to give a slightly firmer feel without compromising on the softness and comfort.

Many quality sofas have high-density foam wrapped in down pads surrounding the springs. This results in a soft, comfortable surface and form-fitting properties - all while preventing the cushions from losing their shape easily. 

Upholstery 

Upholstery is the attachment of padding, cushion, fabric, or leather textile covers on a sofa. Unlike the interior elements that provide the sofa with stability, the material used for upholstery gives each piece a visual identity. When maintained with care, high-performance materials such as top-grain leather can reveal a deeper and richer colour, giving it a luxurious and smoother feel. 

However, the choice of upholstery is also dependent on your interior design and lifestyle. For instance, a fabric sofa gives your living space a warm and contemporary vibe, whereas a classic leather sofa exudes elegance. Furthermore, leather sofas are also durable and easy to maintain as compared to fabric ones.

Sofa Legs

The legs of sofas are mostly made of sturdy materials such as wood and heavy-duty iron. It is recommended that you check the grain and finish consistency for wooden sofa legs. On the other hand, it is important to take into consideration the flooring at home if you are looking to get a sofa with metal legs. This is to ensure that the metal legs of your desired sofa do not cause potential scrape marks on the flooring. 

Sofas, when chosen correctly can turn out to be a great investment for your home. While quality does not come cheap, a premium sofa gives you more comfort and can withstand the tests of time.
