Frequently Asked Questions
Will a seat cushion cure sciatica?
A seat cushion won’t cure sciatica, but the right lumbar or coccyx cushion can reduce pressure on irritated nerves, improve sitting posture and significantly reduce symptoms while sitting. Combine cushions with posture adjustment, stretching and professional guidance for best results.
How firm should a lumbar cushion be?
Firmness is personal: a firmer cushion promotes posture correction and can prevent sinking, while softer memory foam contours and relieves pressure points. If you’re unsure, choose a mid-firm option or a thicker cushion that balances support with comfort.
How do I clean and maintain these cushions?
Most reviewed cushions have removable, machine-washable covers — unzip and follow the manufacturer’s washing instructions. The foam core should be spot-cleaned and air-dried; avoid prolonged sun exposure and machine-washing the foam itself to preserve shape and durability.
