Know before you buy
The Blue Steel Spring™ is a patented, heavy-duty ribbon of steel that provides consistent support and flexibility. Unlike traditional coil springs that can sag or lose tension over time, this system is designed to maintain its shape and comfort for the life of the sofa.
Yes, the seat cushions are fully reversible. This feature allows you to flip and rotate them regularly, which helps distribute wear evenly and keeps the cushions looking fresh for longer.
The Thornton sofa has an inside seat depth of 20 inches. This provides a standard, supportive sit that is comfortable for most adults while maintaining a tidy, upright aesthetic.
Yes, the tapered block legs are available in three different wood finish choices. This allows you to coordinate the base of the sofa with your existing furniture or flooring.
The back cushions are semi-attached, meaning they are secured to the frame to prevent shifting or slouching. This design ensures your sofa maintains a clean, tailored appearance without the need for constant fluffing.
The frame is constructed from sustainably-sourced, kiln-dried wood. The kiln-drying process removes excess moisture to prevent the wood from warping or cracking, ensuring a stable and long-lasting foundation.
