Healthfix appears once on this site, in lumbar and seat cushions, with its memory-foam seat cushion.
A shaped cushion. Memory foam with cutouts placed to take pressure off the sit bones and tailbone; Healthfix says the foam adapts to the body within seconds, and that the design was invented and patented in Germany. A washable, breathable cover sits over it, and anti-slip studs keep it in place.
Made to move. It is the only cushion in the hub with a carry handle, for taking it between a home office, a workplace, a car and travel. The AUVON and Cexovo have neither handle nor straps.
Check the size. The listing we read is size Medium, which suggests other sizes exist, but no dimensions are given — the AUVON is the only seat cushion here with a published size, 43.7 × 41.1 × 7.9 cm. Check the size chart against your chair before ordering.
An endorsement we do not repeat. The listing says the cushion is “recommended by orthopaedists” without naming anyone; this site treats that as marketing. For a specific medical reason, see a doctor or physical therapist.
The price. It is listed on Amazon.com, but no US price could be read when we checked. In Europe it read about €50 to €60 — the highest among the cushions in the hub, against about €13 for the Cexovo and €25 for the AUVON.
