The Jonathan Collection: A breakdown


The Jonathan Sofa offers three distinct material options, each catering to different aesthetics, preferences, and lifestyles.


For the leather option, we use top-grain leather that is pigmented and sourced from the US. This type of leather has been treated to enhance its durability, colour consistency, and resistance to wear and tear. The leather is also lightly embossed and hand-rubbed with a two-tone effect, giving it a rich and sophisticated appearance.

With a thickness of 1.2 to 1.3mm, it provides a robust and luxurious feel, ensuring the sofa not only looks elegant but also stands the test of time.

For those who prefer fabric, the Jonathan Sofa is available in two striking colours: Dark Granite, a greyish-black hue, and Zenith Blue. The fabric composition is a blend of polyester, cotton, and nylon, which combines the durability of polyester, the softness of cotton, and the resilience of nylon.

The combination of these materials results in a fabric that is both comfortable and durable, suitable for families or anyone seeking a practical yet stylish seating option.

Performance fabric

The performance fabric option is ideal for those who prioritise ease of maintenance without sacrificing style. Available in a creamy white colour, this fabric is both spill and stain-resistant, making it an excellent choice for busy households with children or pets

The fabric composition consists of 80% polyester and 20% acrylic, a blend designed to maximise durability and ease of cleaning. This makes the performance fabric a practical choice for high-traffic areas or for those who want to keep their sofa looking pristine with minimal effort. 

The creamy white hue adds a touch of elegance and brightness to any living space, while its practical properties ensure it remains a functional and attractive piece over time.

Suspension and filling

Durability and comfort are further enhanced by the sofa’s sinuous spring suspension system. This type of suspension adds resilience to the seating, allowing the sofa to maintain its shape and support over time. 

The inclusion of pocket springs in the seat cushions provides a bouncy and supportive feel, preventing sagging and ensuring that the sofa retains its comfort and structure. This combination of sinuous springs and pocket springs offers a balanced seating experience that is both firm and plush.

The use of loose fibre in the seat and backrest cushions adds to the plush comfort of the Jonathan Sofa. These cushions conform to the body, providing soft, supportive seating that adapts to various sitting positions.

The Jonathan Sofa’s design epitomises modern elegance with its clean, straight lines and distinct boxy silhouette. One of the standout features of the Jonathan Sofa its boxy shape, which not only enhances its visual appeal but also creates a bold statement in any living room setting. This design approach gives the sofa a contemporary and minimal look that fits seamlessly into various interior styles. 

The sofa features deep seats, measuring about 62.9 cm in depth. This generous seating space is perfect for lounging, providing a sense of enveloping comfort - encouraging relaxation and extended periods of sitting. 

The flange seam detailing of the sofa not only elevates the design but also showcases the meticulous attention to detail. These seams outline the sofa, reinforcing its boxy silhouette and adding a touch of sophistication.

Additionally, its alligator clips keep the sofa units together and can easily be rearranged to fit your space.

The Jonathan Sofa is a model of versatility, designed to seamlessly integrate into a wide range of interior design styles. 

For mid-century modern homes, the leather option of the Jonathan Sofa is particularly appealing. The leather provides a rich, luxurious look that complements the warm wood tones and sleek designs typical of mid-century decor. 

The fabric options are ideal for minimal and modern contemporary spaces as they provide a sleek and understated look that aligns well with the clean, uncluttered ethos of modern design. The simple yet elegant design of the Jonathan Sofa in fabric makes it easy to pair with a variety of decor elements, from bold accent pieces to subtle, monochromatic schemes.

In traditional and mid-century modern aesthetics like @duvaldesignllc’s space, the Jonathan Leather Sofa fits right in.

Despite these specific associations, the Jonathan Sofa transcends strict style boundaries, making it a versatile piece that can adapt to numerous interior styles. The simplicity of its silhouette means it can serve as a quiet backdrop for bolder design elements or as a standout piece in a more subdued setting.

Maintenance and care

Proper maintenance and care are essential to keep the Jonathan Sofa looking its best and ensuring its longevity. 

Here are the general care tips we recommend for Jonathan:

  • Avoid sitting on the arms or frame of the sofa as this can affect the structural integrity of the sofa. 

  • Avoid prolonged exposure to direct sunlight and keep sofa away from any heating source to prevent fading or discolouration.

  • Using a brush attachment, vacuum the sofa regularly to remove any dust particles.

  • Blot spills immediately and gently with a clean white cloth, even for the performance fabric material. Avoid rubbing the spill as this can cause it to spread.

For the leather sofa, here are some specific care tips to keep it looking its best:

  • Use a leather conditioner to keep the leather soft and supple — let dry before sitting.

  • Avoid placing sharp items on the sofa, such as keys or scissors.

  • A patina or slight sheen will develop on the surface of the sofa over time and is part of the normal wear and tear of leather that adds character to the sofa.


Depending on the sofa variations you plan to configure, this determines how many individual units are needed. The price of the Jonathan sofa starts from $1,598 for the fabric options, $1,698 for the performance fabric option, and $2,398 for the leather option. 

These prices are for the Jonathan 3-Seater Sofas, which consists of one left-arm and one right-arm sofa.

Purchasing them as predetermined sofa sets (i.e. L-shape sectional, extended sofa, etc) provides the convenience of having them fully assembled and ensures that you have well-balanced space.


This collection does not require any hands-on assembly as each predetermined configuration comes fully assembled when delivered. 

Assembly is only required if you purchase individual sofa units and decide to customise the configuration of the sofa on your own. But, rest assured that the assembly process is straightforward and manageable with the provided instructions and tools.
