Beautyrest Black Hybrid Series Three XCS review

The XCS models are the cooling branch of Beautyrest Black Hybrid. Series Three XCS, the entry XCS, adds BlackICE Max Cooling Technology, which Beautyrest says provides 30% more cooling power, plus Micro Diamond Memory Foam and a cool-to-the-touch Sleep Climate surface. Pressure relief comes from FORM HD Material under a ContourCover top, and support from the same Triple-Stranded Pocketed Coils as the rest of the Black line. It is also the only Beautyrest we found that comes in Split Head Queen and Split Head King, which matter if each partner wants to raise their own head on an adjustable base. On November 11, 2026, Beautyrest.com listed the queen at $3,399 in all three feels, against a $3,999 compare-at price, and a Twin XL from $2,849. That is a large jump from Series One, so the upgrade makes most sense for hot sleepers or split-base buyers.

Who it is for

Hot sleepers and couples on an adjustable base who want split-head sizing.

Price

From $2,849 for a Twin XL on Beautyrest.com when checked; queen $3,399 during the Black Friday sale.
