Is this mattress responsive, or slow to move on?

It leans toward cushioned support over spring, scoring 7.9 on responsiveness, its lowest axis. Total bounce travel measured a little over 7 inches, at the lower edge of the field, because the deep 3-inch memory layer cradles and slows the surface rather than pushing back quickly. Recovery settles in under about 3 seconds, a deliberate rise typical of a memory-rich build. If you want a plush hug that holds its shape, that slower response is the whole point.
