Eight Sleep recently launched Autopilot 4.0, an AI sleep agent that automatically adjusts a user’s sleep environment through the Pod, the company’s bed heating and cooling system.
By analyzing the user’s day-to-day activities, Autopilot 4.0 predicts nighttime conditions and proactively fine-tunes temperature and comfort before and throughout sleep. Each morning, it provides personalized sleep insights to help users better understand their sleep quality. According to Eight Sleep, the AI has been trained on more than one billion hours of sleep data. This enables it to anticipate users’ sleeping patterns and continuously optimize their sleeping conditions.
Technology behind the Pod series
Eight Sleep was founded in 2014 by Matteo Franceschetti, Alexandra Zatarain, Massimo Andreasi Bassi, and Andrea Ballarini with the goal of optimizing sleep through technology. Its flagship product, the Pod, is powered by the company’s AI platform, which analyzes multiple data sources to personalize the sleep experience. The system combines biometric sensors, environmental sensors, and presence sensors that continuously feed real-time data into its AI platform.
Eight Sleep’s continued innovation has been backed by substantial funding starting with an $86 million Series C in 2021. It subsequently secured $100 million in August 2025 from investors including HSG, Valor Equity Partners, Founders Fund, and Y Combinator. Most recently, in March 2026, it raised $50 million in a strategic round led by Tether Investments. This brings Eight Sleep’s valuation to $1.5 billion. It said that the new capital would go toward new products, expanding into more countries, and deeper clinical research.
Eight Sleep’s Patenting Activity
Eight Sleep’s patent strategy shows a deliberate shift in focus from smart furniture toward biometric health diagnostics. While its 2018 patent filings concentrated heavily on thermal apparatuses and sleep pod enclosures, filings in 2024 shifted toward medical technology and user physiological detection.
This reflects Eight Sleep’s position as an active health-monitoring platform powered by emerging technologies. Notably, the dataset reveals a multi-year gap from 2019 to 2022 with zero active priority filings. Interestingly, this gap in filings coincides with the Pod’s release in 2019.

Patents covering Eight Sleep’s Pod series
Eight Sleep’s Pod series is supported by a portfolio of patents. It covers distinct components of the Pod’s underlying system. The following patents build on one another and are frequently cross-referenced within the filings.
Personalized sleeping experience through the Pod
U.S. Patent No. 11,904,103 covers the “Sleep Pod”, a physical enclosure that regulates not only the sleeping surface but the entire sleep environment. Unlike traditional beds that remain static, the sleep pod continuously monitors the user’s biological signals and automatically adjusts its physical and mechanical properties in real time to optimize comfort and sleep quality.
The sleep pod is designed with separate, independently controlled chambers. This allows multiple individuals to share the same unit while receiving personalized sleep conditions. Adjustments in one chamber can automatically trigger matching or compensating adjustments in the other.
It relies on a network of biological sensors that monitor the user and environmental sensors positioned around the bed. These sensors continuously transmit real-time data to a central processor connected to a database containing the user’s historical sleep data and preferences. By comparing live measurements with historical patterns, the processor generates control signals that dynamically recalibrates its height, inclination, and target pressure areas. Beyond physical adjustments, it also actively regulates the overall sleeping environment by managing noise reduction, soundproofing, ambient light control, air circulation, scent delivery, and white noise generation.
This patent entitled “Sleep pod” was filed on July 16, 2020, and granted on February 20, 2024. Matteo Franceschetti, Massimo Andreasi Bassi, and Daipan Lee are listed as the inventors. Legal representation was provided by Wilson Sonsini Goodrich & Rosati.
Built-in sensors to detect user’s biological signals
U.S. Patent No. 12,274,564 covers a sensor device and system integrated into the Pod that continuously tracks the user’s biometric signals without requiring wearable devices by embedding a shielded piezoelectric sensor directly into the mattress layer.
The system utilizes a flexible printed circuit board (FPC) integrated with a piezoelectric material that serves as the primary sensing element. The piezoelectric material generates electrical signals in response to mechanical stress caused by a user’s breathing, heartbeat, or body movements. By analyzing these biological signals, the system classifies the user’s sleep stage as light sleep, deep sleep, or Rapid Eye Movement (REM) sleep.
Non-wearable sensors are often susceptible to electrical noise, static electricity, and motion-related interference that can reduce signal accuracy. To address this, the sensor is sandwiched between two grounded conductive layers that function as electromagnetic shields, blocking electrical noise, and preventing static charge buildup. An isolation tape layer is positioned between the FPC and the upper conductive shield to electrically insulate the sensor and prevent charge transfer that could otherwise distort measurements.
An analog-to-digital converter (ADC) integrated into the sensor strip converts the raw analog signals into digital data. These signals are then transmitted to the main processor, which filters the data and extracts physiological metrics such as breathing rate, heart rate, and pauses between breaths. Beyond regulating the sleep environment, the processor compares real-time measurements with historical sleep patterns and predefined health thresholds. This enables the early detection of potential health abnormalities or the onset of a disease.
This patent entitled “Systems and methods for detecting a biological signal of a user of an article of furniture” was filed on April 25, 2023, and granted on April 15, 2025. Matteo Franceschetti and Massimo Andreasi Bassi are listed as the inventors. Legal representation was provided by Wilson Sonsini Goodrich & Rosati.
Temperature regulation of sleeping devices
U.S. Pat. App. Pub. No. 2026/0041252 covers an automated, multi-zone temperature regulation system for the Sleep Pod that delivers personalized thermal comfort by coordinating biometric data with embedded fluid channels, thermoelectric elements, and independently controlled heating coils.
Conventional temperature-regulated bedding typically relies on manual controls and provides uniform, static heating or cooling. As a result, it cannot respond to changing body temperatures, different sleep stages, or the varying comfort preferences of individuals sharing the same bed.
To address these limitations, the system incorporates internal channels that circulate a heat-transfer medium, such as water or air, to either remove heat from or deliver heat to the user. It also integrates solid-state thermoelectric elements that create heating and cooling effects by transferring heat when an electrical current is applied. A phase change material further improves thermal management by absorbing heat from the thermoelectric elements and distributing it away from the user’s sleeping area.
Consistent with the Sleep Pod’s independent chamber design, the system enables two individuals sharing the same bed to maintain different temperature settings simultaneously. For example, one side of the mattress can be actively heated while the other is cooled. This multi-zone temperature control is managed by the Pod’s power management system, which independently powers dedicated heating coils for each sleep zone.
This patent entitled “Systems and methods for regulating a temperature of an article of furniture” was filed on October 20, 2025 and published on February 12, 2026. Matteo Franceschetti, Daipan Lee, William Goethals, William Henry Harrison Cowles, Massimo Andreasi Bassi, Daan Stevenson, Charles Irick, and Paul Katz are listed as the inventors.
