SPC-1015 is a fully-formulated slow-recovery (memory-foam) polyol system for moulding back & lumbar support cushions — office and car lumbar cushions, seat & donut cushions and massage-point supports. The viscoelastic foam contours to the back and slowly returns to shape, distributing pressure for ergonomic support and lasting comfort. A two-component blended-polyol system with firmness and recovery adjustable to your cushion.
