Frequently Asked Questions
What is the Beautyrest Black Hybrid XCS?
The Beautyrest Black Hybrid XCS is Simmons' most advanced hybrid mattress, combining Triple-Stranded Pocketed Coil Technology with multiple layers of specialty pressure-relieving foam and proprietary BlackICE Max cooling technology. It's engineered for sleepers who want the responsive feel of a coil system with the deep contouring comfort of premium foam — all with an emphasis on staying cool throughout the night.
What comfort levels does the Beautyrest Black Hybrid XCS come in?
The Beautyrest Black Hybrid XCS is available in three comfort levels: Plush (soft, pressure-relieving), Medium (balanced support and cushioning), and Firm (supportive with minimal sink). Multiple series options — Series Three, Four, and Five — are also available at different price and comfort tiers. Our sleep specialists can help you identify which feel is best suited for your sleep position and body type.
What is BlackICE Max technology?
BlackICE Max is Beautyrest Black's advanced cooling system, featured exclusively on XCS models. It works through a combination of a ContourCover surface that's cool to the touch, ventilated foam layers that promote airflow throughout the mattress, and phase-change materials that absorb and dissipate body heat. The result is a sleep surface that stays measurably cooler than standard hybrid mattresses throughout the night.
What sizes is the Beautyrest Black Hybrid XCS available in?
The Beautyrest Black Hybrid XCS is available in Twin, Twin XL, Full, Queen, King, California King, and Split Head sizes. The Split Head option (available in Queen and King) lets each sleeper independently adjust the head of the bed, making it an ideal pairing with an adjustable base.
Is the Beautyrest Black Hybrid XCS good for couples?
Yes — it's one of the top-rated mattresses for couples. The Triple-Stranded Pocketed Coil system earned the highest possible score for motion isolation in independent testing, meaning movement on one side of the bed is not transferred to the other. Combined with zoned support and the Split Head option for adjustable base compatibility, it's a strong choice for partners with different sleep preferences.
Can I try the Beautyrest Black Hybrid XCS in person?
Absolutely. Mattress World Northwest carries Beautyrest Black at our Portland Metro area and Willamette Valley showrooms. Come in and lie down on multiple comfort levels side by side — there's no substitute for testing a mattress yourself. Our sleep specialists are here to answer questions and help you find the right feel without any pressure.
