Cluneal Cushion: Choose the Right One

Cluneal neuralgia is caused by inflammation of the cluneal nerve, located in the pelvis. It can cause burning sensations, tingling, numbness, or electric shocks. Due to its position, the cluneal nerve can become compressed by the ischium (sit bone) while seated, or by the piriformis muscle.

Among non-drug solutions to relieve cluneal neuralgia, seat cushions are quite popular. Ergotech offers two models specifically designed to reduce cluneal nerve compression and help relieve pain: the Cluneal seat with High Viscosity Fluid and its new version with memory foam.

Overview of the Two Cluneal Cushion Models

Cluneal Cushion – High Viscosity Fluid Version

The Cluneal seat is specially designed for people suffering from cluneal neuralgia. A cut-out targets the cluneal nerve area to eliminate pressure on it:

• • High-resilience foam structure with high-viscosity fluid
• • Bowl-shaped cut-out for sacrum-to-perineum relief
• • Reduces pressure with 4 high-viscosity fluid pouches that move under the weight and movements
• • Absorbs shocks and micro-vibrations in the car
• • Suitable for use at home, office, or in a vehicle

Advantages: lightweight, easy to transport

Cluneal Cushion – Memory Foam Version

In this new version, the cut-out remains unchanged, but the high-viscosity fluid pockets are replaced with memory foam.

• • High-resilience foam with memory foam layer
• • Bowl-shaped cut-out for sacrum-to-perineum relief
• • Reduces pressure on all contact zones (thighs, buttocks)
• • Lower shock and vibration absorption in vehicles due to absence of fluid
• • Suitable for muscular sensitivity, piriformis syndrome, or myofascial syndrome

Advantages: pressure relief across all support areas

Which Cluneal Cushion to Choose?

What’s the Difference Between the Two?

The choice between the two depends on your specific case of cluneal neuralgia.

• • Cluneal Cushion with High Viscosity Fluid: Ergotech’s original model has already prod its efficiency and is suitable for all forms of clunealgia.
• • Cluneal Cushion with Memory Foam: Initially a custom model, added to the catalog due to positive feedback. Ideal for users with muscular sensitivity in the thighs or buttocks. The memory foam adds height, softens contact pressure, and reduces overall compression.

Both cushions are available in 4 sizes and 3 firmness levels to suit different body types and usage settings (home, work, car, etc.).
