The only seat cushion here with a published size — and medical claims this site does not repeat
AUVON appears once on this site, in lumbar and seat cushions, with its memory-foam seat cushion.
A size you can check. 43.7 × 41.1 × 7.9 cm (17.2 × 16.2 × 3.1 in) — the only seat cushion in the hub to publish its dimensions. The Cexovo gives none, and the Healthfix only says “medium”. Measure your chair’s seat before buying: a cushion wider or deeper than the seat overhangs it.
A specific shape. A central hole and a U-shaped cutout at the back keep the tailbone clear of the seat, and a sloped front edge sits under the thighs — a different design from a flat pad. The cushion also adds about 8 cm (3.1 in) of height, so the chair may need lowering to keep your feet flat.
The material. AUVON states dense memory foam, which it contrasts with cheaper polyurethane foam, under a removable, washable honeycomb mesh cover with a non-slip base. There are no straps and no carry handle — the Healthfix has a handle, if you move the cushion between chairs.
Claims we do not repeat. The listing sells the cushion for hemorrhoids, sciatica and pressure sores. Those are medical claims a seat cushion’s listing cannot establish, and this site does not repeat them. For persistent pain, see a doctor or physical therapist.
It had no US price when we checked.
Seat cushion · memory foam · U-shaped cutout · 43.7 × 41.1 × 7.9 cm (17.2 × 16.2 × 3.1 in)
A memory-foam seat cushion with a central hole and a U-shaped tailbone cutout, 43.7 × 41.1 × 7.9 cm (17.2 × 16.2 × 3.1 in), under a removable honeycomb mesh cover — the only seat cushion here with a published size.
Best for: Someone who wants the tailbone kept clear of the seat, and a size to check against the chair.
