Does this plush hybrid sleep hot?

No, it is exceptionally cool, scoring a perfect 10/10 for cooling. The inch you touch is natural latex, whose pinhole cell structure breathes instead of trapping heat like a solid memory-foam slab. Peak temperature holds in the 29.1 to 31.9C range with only a 7.1 to 9.9C rise overnight. Below the comfort stack, 1000 pocketed coils keep air moving through the core. The thin gel-memory layer sits beneath the latex, never pressed against your back.
