FABRIC SELECTION
Choose the fabric that fits your life
Explore a wide selection of fabrics in different colours and textures, allowing you to create a sofa that feels uniquely yours. From a clean, understated look to a richer tactile finish, there is an upholstery option to suit your style.
Beyond appearance, each fabric offers practical benefits. Pet friendly fabrics are well suited for homes with pets, easy clean fabrics simplify maintenance, while cotton and linen blends offer better breathability and a cooler feel.
REMOVABLE COVER
Change the look without changing the sofa
A sofa often stays with you through changing homes, lifestyles, and design preferences. With removable covers, you can refresh its appearance with a new colour or fabric without changing the entire piece.
Life happens around the sofa. Everyday use gradually leaves its mark overtime. Removable covers make it possible to wash and refresh your sofa as needed. Best paired with our washable fabric series for easier long-term care.
CUSHION CONFIGURATION
Medium soft firmness
The default seat cushions are made with a white goose down feather top layer and a high density foam support layer(over 40kg/m³) . Together, they create a plush, cushioned feel with medium soft firmness.
When sitting on it, you experience the soft, enveloping comfort of the down feather layer first, followed by the support of the foam layer underneath. The result is a comfortable seat that feels inviting for everyday lounging.
SEAT CUSHION SUPPORT LAYER
High density foam that retains shape
Foam density measures the amount of material within the foam. We use high density 40kg/m³ foam for the support layer, compared to lower density alternatives below 30kg/m³.
This helps the cushion retain its shape and support for longer, reducing the likelihood of premature sagging from everyday use.
WOOD FRAME
Solid wood for key frame components
We use kiln-dried solid larch wood for the key structural components of our sofas. Its natural strength and stability help the sofa maintain its shape and support through years of everyday use.
Compared to engineered alternatives, solid wood retains its strength better under repeated loading, making it well suited for areas subjected to the highest daily stresses.
