2. Boxed Edge Cushions for Structured Support

Boxed edge deep seating cushions feature straight sides and a tailored appearance. This construction style provides a clean, structured look while still offering comfort.

The boxed edges help the cushion retain its shape, preventing sagging over time. This makes them ideal for modern or classic outdoor furniture where crisp lines are part of the design.

Inside, these cushions typically contain layered foam—firm at the base and slightly softer on top—to support posture while maintaining comfort.
