Nordspur | Sedenna Contoured Structured Doughnut Cushion

This contoured doughnut cushion brings structured support to any chair with its 7 cm thickness.

Sitting at a desk or in a car for hours often leads to a stiff lower back and general discomfort. Finding a way to ease that tension without buying a completely new chair can be difficult.

• Contoured hollow-centre seating design
• Slow-rebound shape-adapting core
• Dedicated rear tailbone support zone
• Slip-resistant textured base pattern

Targeted pressure distribution
A central cutout and dedicated tailbone support zone work together to shift weight away from sensitive areas. This hollow-centre design provides a suspended feel for the lower back.

Structured posture support
Built-in concave thigh zones guide the legs into a natural, forward-facing position. This contoured surface aligns the body rather than letting it sink unevenly into the seat.

Stable and slip-resistant
The underside features a textured dotted pattern designed to grip flat surfaces. This base resists sliding on smooth hard chair surfaces.

Substantial 7 cm thickness
A dual-layer, slow-rebound core provides a noticeable 7 cm of height and cushioning. This dense construction compresses just enough to match your shape without flattening out completely.
