Frequently Asked Questions
Will a seat cushion cure my sciatica?
A seat cushion won't cure sciatica but can significantly reduce pressure on the coccyx and sit bones, easing pain while seated. Combine a good cushion with posture adjustments, movement breaks, and guidance from a healthcare professional for best results.
How thick should a sciatica cushion be?
Thickness depends on your chair and body: 3–3.5 inches is suitable for moderate cushioning and posture support, while 4–5+ inches provides extra padding for very hard seats or users who want more separation from a firm surface. Keep in mind thicker cushions can change seating height and posture.
Can I use these cushions in my car or airplane?
Yes — most cushions here are designed for multi-use (office, car, airplane, wheelchair). Look for non-slip bottoms and a carry handle for travel; note that very thick cushions may not fit well under seat belts or in some airline seats.
