Gaiam Zafu Organic Cotton Meditation Cushion Pillow

₹3,499

The adjustable fill is the feature, not the fabric.

Zacurate

₹1,999

Competent hardware carrying two caveats worth knowing.

Buy it if: Anyone sitting to meditate who needs the seat height matched to their own flexibility.

Avoid it if: Anyone wanting a light, packable cushion -- buckwheat fill makes this heavy.

Buy it if: Anyone who wants an FDA-cleared oximeter and does not need Indian regulatory approval.

Avoid it if: Anyone wanting a CDSCO-registered device, or a perfusion index to judge reading quality.
