Yes, it is recommended to use a Box Spring with the Beautyrest Black® Series Two 14.25" Firm Mattress. Box springs provide mattress support, and improved airflow. They can also help distribute weight and reduce sagging while adding bed height.

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.

Mattresses last an average of 8-10 years.

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.

This mattress is designed to feel more stable and supportive right from the top, with less sink than a medium or plush option. If you like a firmer surface for a more "on top of the bed" feel, this comfort level is a strong match.

The Triple Stranded Pocketed Coil Technology uses individually wrapped coils, which are designed to respond more independently to movement. That can help reduce how much motion you feel when someone else changes positions during the night.

SurfaceTouch Gel Memory Foam and Micro Diamond Memory Foam are designed to provide an inviting first touch while promoting cooling and pressure relief. Together, they help create a more comfortable surface without changing the overall firm support of the mattress.

This model includes temperature management features plus cooling-focused foam upgrades that are designed to help the surface feel more comfortable through the night. If you frequently overheat, pairing it with breathable bedding can help you get the most out of the cooling design.

It can be a great option for sleepers who want a firm feel with luxury-level materials and a more supportive, responsive core. It also makes sense for people who value motion separation but do not want a soft, deep-sinking feel.

With a 14.25-inch profile, many sheet sets will fit, but some standard-pocket sheets may feel snug depending on your bedding and protector. If you prefer an easier fit, look for sheet options made for thicker mattresses.
