Pocketed coils (wrapped coils)
Springs individually encased in fabric sleeves so each coil compresses independently. Better motion isolation and contouring than interconnected (Bonnell or continuous-wire) coil grids. Coil count matters less than marketing implies once past ~800 in a queen; coil gauge (wire thickness) matters more for support and longevity.
