Yes, it is recommended to use a Box Spring with the Sealy Posturepedic® Plus Norman II 15" Medium Euro Top 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.

You can expect a balanced feel with noticeable cushioning at the surface and a more supportive, stable response as you settle in. The euro top gives a smooth, built-in comfort layer, while the support system underneath is designed to keep you from feeling like you are sinking too deeply.

Support comes from the Posturepedic Plus Support System with PrecisionFit Coils placed where you need them most. This design is intended to help maintain more natural body alignment and promote a steadier feel across key areas.

The PrecisionFit Coils are individually wrapped, which helps limit motion transfer compared to connected coil systems. A queen size has 966 coils, so the surface can respond more locally to movement instead of rippling across the bed.

SealyComfort Gel Memory Foam contours to your body to help with pressure relief and more even weight distribution. SealyComfort Gel Foam Medium adds responsive cushioning, helping the top feel comfortable while still staying supportive.

The DuraFlex Coil Edge extends support around the mattress perimeter. This can help the mattress feel more consistent closer to the sides and feel steadier when you sit or sleep near the edge.

Medium comfort levels are often a good fit if you want a mix of cushioning and support, especially if you are unsure whether to go firm or plush. If you want help dialing in the right feel for your sleep style, a Mattress Firm Sleep Experts® team member can guide you through the options.
