The surface and gusset use 250gsm flame-retardant polyester jacquard air layer fabric for a soft, breathable feel. A 95gsm microfibre base with anti-slip flame-retardant rubber keeps it in place. Inside, 45D high-density memory foam responds to heat and pressure for personalised support, reduced motion transfer, and pressure relief.
