Does this mattress need a box spring?
Yes, it is recommended to use a Box Spring with the Beautyrest Black® Series Three 14.25" Extra Firm 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.
