Does the GlacioTex cover really keep it cool?

GlacioTex is a cooling fabric, and some owners say it helps. Memory foam still traps heat, and a number of reviewers say they sleep warm on it.

Should I pick Luxury Plush or Luxury Firm?

Pick Plush to soften a hard mattress and Firm to add support to a soft one. The two feels are quite different, so match it to what your bed lacks.

It adds 3 inches of height, so fitted sheets with shallow pockets may not stretch over it. Deep-pocket sheets are the safer choice.

It adds comfort on top but does not correct a deep dip or broken support. For a badly sagging mattress, a new mattress is the real fix.

Place it directly on a clean mattress surface and pull the cover taut. Some owners still see movement on smooth mattress tops.
