0%Eight Sleep and Resmed partner to help people better understand and improve their sleep health. Resmed makes an investment in Eight Sleep as the companies collaborate to connect sleep insights and expand access to sleep health resources New York, NY and San Diego, CA / Oct 16, 2026 / Eight Sleep Eight Sleep, a leading AI-powered sleep technology company, and Resmed (NYSE: RMD, ASX: RMD), the leading health technology company focused on sleep, breathing, and care delivered in the home, today announced they are partnering to help people in the U.S. and Australia better understand their sleep health by bridging Eight Sleep's technology with sleep insights from Resmed. As part of the collaboration, Resmed has also made an investment in Eight Sleep. Sleep is a foundational pillar of health alongside nutrition and exercise, yet it remains underprioritized and misunderstood.[1] Millions of people with sleep disorders, including obstructive sleep apnea (OSA), remain undiagnosed.[2] At the same time, consumer sleep technology is giving people more visibility into their sleep patterns. Resmed's connection to Eight Sleep is designed to help people bring more of their sleep information together and learn where they can find additional education and support. "At Eight Sleep, we're focused on transforming the bed and bedroom into a preventative and predictive health platform," said Matteo Franceschetti, co-founder and CEO of Eight Sleep. "This collaboration allows Eight Sleep members who use a Resmed PAP device with the myAir(TM) app to gain broader insights into their sleep health directly through our AI-powered platform. Resmed's investment also supports the role Eight Sleep can play in the future of sleep health." Bringing myAir sleep therapy insights into the Eight Sleep experience People in the U.S. and Australia who use both a Resmed PAP device with the myAir app and an Eight Sleep Pod can securely connect their myAir PAP therapy insights directly to the Eight Sleep app. With the user's permission, myAir insights will appear alongside Eight Sleep metrics, such as heart rate, breathing rate, and snoring-related data. This will allow members to view their Eight Sleep and myAir insights together and follow them over time. Data sharing is optional, requires the user's permission, and can be disconnected at any time. Connecting Eight Sleep members with educational sleep health resources In Australia, Eight Sleep users can learn more about their sleep health based on trends observed in their sleep data, including snoring-related insights. They may be guided to Resmed resources and available support options, including a sleep assessment to better understand their sleep health. By combining Resmed's expertise in sleep health with Eight Sleep's AI-powered sleep platform, the companies aim to help people better understand their sleep and access educational resources. "Resmed is committed to improving lives through better sleep and breathing, with care delivered in the home," said Carlos Nunez, MD, Chief Medical Officer, Resmed. "As more people use consumer technology for sleep, we have an opportunity to help turn those insights into a greater understanding of sleep health. Our work with Eight Sleep helps us reach more people earlier in their sleep health journey, driving greater awareness and education so they can seek diagnosis and treatment from their healthcare provider if needed." Availability Integration between the myAir and Eight Sleep consumer apps is now live in the U.S. and Australia, alongside the sleep health resources in Australia. The companies plan to expand the collaboration to additional markets over time. Connecting myAir insights in the Eight Sleep app requires an active Eight Sleep Autopilot membership.

Eight Sleep launches Pod 6 with smaller hub and cheaper entry price. The sleep tech company launched the smallest Pod of its lineup yet and introduced new sizes. Managing Editor Nasha is the Head of Editorial Initiatives for CNET... Read full bio September 23, 2026, 9:02 am ET Eight Sleep, a sleep tech company, launched the Pod 6 bed-cooling system on Wednesday with meaningful hardware changes, including a hub that's half the size of its predecessor, new solo-size configurations and a $1,999 starting price for the solo sizes - the lowest the company has offered. The entry price for standard sizes will be $2,699. "We redesigned the hub, so it is 50% shorter than Pod 5, while increasing thermal power. That requires a more efficient approach to the system's internal architecture, thermal management, fluid movement and overall packaging," Matteo Franceschetti, CEO and co-founder of Eight Sleep, told CNET. The smaller hub can slide under most standard bed frames. For the first time since the Pod launched in 2019, customers can choose solo-size options like twin XL and half sizes for queen, king and California king. Until now, the Pod has been built for couples with standard mattress sizes. "For six generations, the Pod's dual-zone design has been extremely valuable for couples, because each person can independently control their temperature and receive their own sleep data. But there are many people who want that same experience for just one side of the bed, or in a bedroom with a twin XL or split-mattress configuration," Franceschetti said. The Pod 6 has nine times more sensors per side and AI-powered tracking for more accurate sleep insights. The redesigned hub delivers 40% to 50% more thermal power for faster temperature response. Franceschetti said that the main advantage of having more sensors is improved precision and consistent tracking across different sleep positions. "People move throughout the night, and a higher density of sensors gives the system more opportunities to maintain a reliable signal, whether someone is on their back, side or shifting position." With these updates, the Pod 6 aims to make advanced sleep technology more accessible and versatile for individual sleepers and couples alike.

The company expects to reach $1 billion in lifetime Pod sales by year-end. The Pod line represents Eight Sleep's signature product, featuring high-tech temperature control functionality. The new models aim to make the technology more accessible whilst maintaining the features that established the brand's reputation in the sleep technology market.
Your bedding can now tell you how fast you're aging (thanks in part to biohacker Bryan Johnson). Published Sep. 3, 2026, 9:00 a.m. ET See more of our coverage in your search results. More people are looking to get the most out of their nightly slumber, turning to high-tech mattresses and bedding to track their sleep data and achieve a perfect night's rest. Now, the brand that once described itself as a "sleep fitness" company has partnered with the "immortal uncle" to offer a way to see how fast you're aging while catching some Z's. Eight Sleep, maker of the buzzy Pod bed cooling system, has just added a biological age feature to help users better understand not just how well they're sleeping - but also how well they're aging. The company developed the latest tech with biohacker and longevity mogul Bryan Johnson, a longtime advocate of prioritizing sleep who has used the Pod for years. "Bryan has spent years focused on measuring the factors that influence the pace of aging," Matteo Franceschetti, co-founder and CEO at Eight Sleep, told The Post. "That perspective helped shape how we think about making longevity data more accessible and useful in everyday life." The Eight Sleep Pod system consists of cooling pillow covers, a mattress cover to track biometric data, a hydro-powered blanket that connects to the cover and a hub, which powers the system. Using sensors built directly into the Pod mattress cover, the new feature measures several biological signs of aging - including heart rate, heart rate variability, respiratory rate, sleep stages, and sleep duration - and can account for individual metrics of two people in the same bed at the same time. Users also have the option of connecting a wearable fitness tracker, like an Apple Watch, to add data from their daytime activities and medical records for a more comprehensive picture. Unlike chronological age - the time that's passed since a person's birth - biological age measures the functional condition of a person's cells, tissues and organs. Several factors play a role in how well someone ages biologically, including genetics, weight, environmental exposures and lifestyle habits, such as diet, exercise and, of course, sleep. "Because it is part of the bed, the experience is effortless," Franceschetti explained. "You simply sleep in comfort while the Pod builds a continuous picture of how your body is functioning night after night." To ensure the cover's sensors provided the most accurate results, measurements were validated against clinical gold standards. For instance, sleeping heart rate was 99% accurate compared with an ECG, while respiratory rate was 98% accurate compared with respiratory inductance plethysmography, a tool used to measure lung volume and breathing patterns. "For Biological Age specifically, we trained a new health foundation model using data from more than 100,000 participants and 2.7 million hours of biometric data collected during sleep," Franceschetti explained. "That accuracy is the foundation for Biological Age." Along with biological age, the system also focuses on speed of aging, or the estimated pace at which the body is aging relative to calendar time. While Biological Age and the Pod aren't meant to replace clinical care, consistency is key to fully understanding how someone's health is "changing over time relative to their own baseline, while also comparing those patterns with people of similar age and gender," according to Franceschetti. "I think Eight Sleep customers will love the Biological Age because it can help them build intuition around how their lifestyle choices affect their health," Johnson said in a press release from Eight Sleep. The most current Pod system runs for $2,999 with a five-year warranty. Eight Sleep offers a 30-night risk-free trial, as well as free shipping and free returns.
Eight Sleep, maker of a $2,999 smart mattress cover, is pursuing FDA clearance to detect and treat sleep apnea. Chief executive Matteo Franceschetti said the filing is progressing "fairly smoothly" and the company is conducting clinical studies. The company aims to position the Pod as a prescription diagnostic device and CPAP alternative, hoping insurers will cover it rather than relying on out-of-pocket purchases. Eight Sleep raised $50 million from Tether in March at a $1.5 billion valuation and was profitable in 2025. The firm has raised over $310 million total and now sells in 35 countries. Cumulative Pod sales exceed $500 million, according to Franceschetti. The company is also conducting trials in Abu Dhabi testing whether the Pod can automatically reposition sleep apnea patients.
