Product Details
The Beautyrest Silver BRS900 12” plush mattressr is engineered to maintain its shape and consistent comfort over the life of your mattress, so that your sleep will be every bit as restful years from now, as it is today.
Featuring 900 Series Beautyrest® Pocketed Coil® Technology that provides flexible support precisely where it is needed and isolates motion between two sleepers. 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. Get the soft support right where you need it most with Gel Memory Foam Lumbar Support.
Benefits
1.25 inches of breathable AirFeel® Foam and 1.25 inches of plush comfort foam provide cushioning pressure relief for your curves, and keep you at a comfortable temperature while you sleep.
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.
The firm pocketed coil 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 more peaceful sleep.
The trusted Beautyrest® Plush 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.
You, your bedding, and your mattress stay fresh and dry with Beautyrest's DualCool™ Technology. It features fibers enhanced with silver, which provide antimicrobial performance, moisture wicking, and heat dissipation.

Does this mattress need a box spring?
Yes, it is recommended to use a Box Spring with the Beautyrest Silver® BRS900 12" Plush Mattress. Box springs provide mattress support, and improved airflow. They can also help distribute weight and reduce sagging while adding bed height.
What is a split king mattress?
A split king mattress is made up of two Twin XL mattresses placed side by side. This size is a great option for some couples because it features two separate mattresses for independent movement. There's a split in the bed so you can each select your own comfort level.
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.
