Benefits
The DualCool™ Technology found in the Silver BRS900, is an antimicrobial performance layer that works to keep your mattress fresh and cool while moving heat and moisture away, so you sleep at your ideal sleeping temperature.
This pocketed coil support system, with a 900-coil density, provides flexible support for your entire body. Each coil is wrapped in a durable fabric sleeve to isolate motion between you and your partner, so you get a peaceful sleep.
The trusted Beautyrest® Extra Firm Pocketed Coil® System has a 900-coil density so you get even more support and durability than the BR800 model. For additional posterized support for your lower back, a gel memory foam lumbar support is positioned in the middle third of the mattress.
Sleep at your ideal temperature as the DualCool™ Technology in the antimicrobial performance layer channels heat and moisture away from your body. This keeps you, your mattress, and your bedding fresh and dry.
One inch of breathable AirCool® Foam and 1.5 inches of firm comfort foam provide pressure relief and a firm sleep surface, and keep you at a comfortable temperature while you sleep.

What is a split king mattress?

How long does a mattress last?
Mattresses last an average of 8-10 years.
How do you clean a mattress?
Cleaning a mattress is a simple step-by-step process. First, remove all bedding and covers to wash separately. Then, use the upholstery attachment on your vacuum cleaner to thoroughly vacuum the entire surface of the mattress, paying special attention to seams, crevices and edges. Then, spot-clean stains where needed using different solutions depending on the stain type. Once the mattress is clean, sprinkle a generous layer of baking soda over the surface to deodorize. After a few hours (ideally overnight), vacuum the mattress thoroughly to remove all residue.
