Does the iComfort Zip Medium feel slow like typical memory foam?

No, it is unusually lively for foam, scoring 9.5 out of 10 on responsiveness. With only 1 inch of memory foam over a resilient poly comfort section, the surface reforms in under 2.9 seconds rather than holding a dent, so you can shift positions without fighting a sinkhole. Bounce travel sits in the 6.09 to 8.61 inch range. Combination and active sleepers get an easy-to-move-on surface, though a coil hybrid still bounces more.
