![]() Smart bed users receive information about estimated sleep timing, duration, and quality via a consumer smart phone app on a daily basis. The smart bed sensors automatically begin data collection as soon as the user enters the bed and stop once the user leaves. The use of BCG as a passive-sensing technology enables the measurement of motion, position changes, breathing, and small movements within the body such as those generated by the ejection of blood with each heartbeat. Similar to bed surfaces in sleep laboratories or specialized medical care units and to under-mattress monitoring devices used by consumers, the smart bed sensing technology uses high-resolution full-body ballistocardiography (BCG) readings from an inflatable air bladder within the bed mattress, underlying the entire body of a single sleeper. The Sleep Number smart bed evaluates the sleeper’s bed presence, body movements, heartbeat, and breathing patterns in real time to determine the duration and quality of sleep. Overall, the findings suggest that the Sleep Number smart bed may provide reliable metrics to unobtrusively characterize human sleep under real life-conditions. ![]() ![]() For all-night summary variables, agreement was moderate to strong. Epoch-by-epoch HR and BR were highly correlated with PSG (HR: r = 0.81, |bias| = 0.23 beats/min BR: r = 0.71, |bias| = 0.08 breaths/min), as were estimations of mean overnight HR and BR (HR: r = 0.94, |bias| = 0.15 beats/min BR: r = 0.96, |bias| = 0.09 breaths/min). ![]() wake classification was quantified using Cohen’s kappa, ROC analysis, sensitivity, specificity, accuracy, and precision. Smart bed data were compared to PSG by Bland–Altman analysis and Pearson correlation for epoch-by-epoch HR and epoch-by-epoch BR. Forty-five participants (aged 22–64 years 55% women) slept one night on the smart bed with standard PSG. wake, mean overnight HR and BR, and summary sleep variables. This study evaluated the performance of the smart bed relative to polysomnography (PSG) in estimating epoch-by-epoch HR, BR, sleep vs. Keep in mind that most latex foam beds you buy online come with a risk-free trial, so you can make the switch back to the kind of mattress you're used to if you don't like it.įor more information on choosing the best products for sleep, take a look at our post on how to choose a mattress type and how to pick the perfect pillow.The Sleep Number smart bed uses embedded ballistocardiography, together with network connectivity, signal processing, and machine learning, to detect heart rate (HR), breathing rate (BR), and sleep vs. Just the sound of "latex" foam may put some people off, but I think many will find it pretty comfortable if they give it a chance. I didn't know what latex foam was before I started testing mattresses, comparing and researching bedding materials. I personally sleep on the Brooklyn Bedding Bloom mattress and as I've said before, it's one of the best beds I've ever tested. I have noticed that latex foam used to lean toward the firm end of the spectrum, but I'm seeing more and more brands make latex foam beds with a medium firmness or softer. It's also a heck of a lot more durable a plus if you have pets who like to claw and crawl their way into bed with you. I don't feel stuck inside the foam like I do with latex foam, and it's a bit more breathable than memory foam and polyurethane foam. The pillow top makes a bed feel fluffy and plush, while the latex foam is breathable, bouncy and supportive. Latex foam is often paired with a pillow top that contains wool and organic cotton, a magical trio that makes sleeping enjoyable (and easy). One reason why I love latex foam is because of its light, airy and bouncy feel. One of the most popular beds that utilize this type of latex foam is the GhostBed mattress, and it's a super comfortable bed with a mixed foam feel. So you can still get that latex foam feel without paying top dollar. On the flip side, the benefit of synthetic latex foam is that it tends to be cheaper than organic material. However, it's not hypoallergenic, antimicrobial or eco-friendly. Synthetic latex foam has some of the same benefits like durability, supportiveness and breathability. This makes natural latex foam especially ideal for people who suffer from allergies and/or sleep hot during the night. ![]()
