Distinction sits at the top of the IntelliQube line, and the difference is that the cooling is not a cover trick. Copper memory foam, graphite latex and Kikoo strips all pull heat sideways and out from under you, instead of trapping it in the comfort layers.

Below that sits the patented GelShell system: more than eleven hundred small, high-density memory foam cubes that move independently, which is what keeps a partner rolling over from reaching your side of the bed. A five-zone pocketed coil unit handles alignment, firmer coils under the hips and softer ones at the shoulders, and a foam-encased edge keeps the perimeter sittable. Qube handcrafts it in the Pacific Northwest and backs it with a 20-year warranty. King size, for hot sleepers who share a bed and want the plush end of the range.
