Your search for an extremely firm sleeping experience ends with the BeautyrestÂ® Platinumâ„¢ Holloway Extra Firm mattress. This mattress is the firmest model in the Beautyrest Platinum collection and is a great option for stomach sleepers. It is designed for people looking for a very firm, dense overall feel. The Holloway mattress may have an extra firm feel in terms of comfort, but it is luxuriously soft to the touch. Located just beneath the luxury knit cover is Infinicoolâ„¢ Surface with ActivPurâ„¢ antimicrobial technology. The surface fibers are infused with cooling technology to help move heat away from the body to help regulate your sleep temperature throughout the night. The fibers also contain antimicrobial properties to help prevent odor-causing bacteria, mold and mildew to help keep your mattress fresh. A unique layer of BeautyrestÂ® Gel Memory Foam helps maintain a comfortable sleep temperature while offering advanced pressure point relief. The 1000 Density Pocketed CoilÂ® technology in the mattress's core is a heavier gauge wire which helps provide the firm support you need, with enhanced conformability and motion separation, thanks to ultra-responsive, individually wrapped coils. The Beautyrest mattress also comes with our complimentary smart-bed bundle, featuring the Beautyrest SleeptrackerÂ® monitor. It's a unique technology that monitors your sleeping behavior and synthesizes your data-coaching you into your best sleep shape. The Beautyrest Sleeptracker monitor is included in the purchase of any Beautyrest Platinum mattress. When the bed is delivered, a warranty card details instructions for ordering the monitor.
