How responsive is it for moving and repositioning?

It favors cushioned comfort over snappy bounce, recovering a little slower than the firmer models here as the thick foam settles back, with response under about 2 seconds. The 630 pocketed coils keep enough life under the surface that you will not feel stuck, but if instant, athletic responsiveness is your priority, a firmer build moves quicker. For a deeply plush 14-inch mattress, this is a reasonable trade for the pressure relief it delivers.
