What Sets EightSleep Apart

These core, shared features are the ones that most people will want.

• Automatic cooling and heating on each side of the bed allow partners to set individual temperature preferences that EightSleep adjusts as your sleep stages progress through the night.
• Sleep and health tracking without a wearable, including tracking sleep stages, heart rate, heart rate variability (HRV), snoring, and breathing rate. The sleep stage tracking and heart rate/HRV measurements are accurate, making this a reference-grade tracker.
• Vibration and thermal alarms. The thermal alarm heats the bed to help you wake up. The Ultra model also adds an audible alarm.

Feature Differences

There are three versions of the Pod 5 available. Most people get the CORE option, which goes around their existing mattress.

1. Pod 5 Core: This base model includes the mattress cover and the Hub.
   • Key Features: Essential temperature control with cooling and heating on each side of the bed, sleep and health tracking, and vibration and thermal alarms.
   • Pricing: In the US, the full-size starts at $2,849, about $400 more than the Pod 4 counterpart due to tariffs. In the EU/UK, a UK Double size starts at £2,649 (on offer from £2,749). A large double size in the EU begins at €3,049 (on offer from €3,149).
2. Pod 5 Plus: This version builds upon the Core model by adding a temperature-regulated blanket.
   • Key Features: Includes the Cover, Hub, and Blanket. It offers immersive temperature control with 2x cooling and heating capacity, thanks to the blanket syncing with the cover, sleep and health tracking, and vibration and thermal alarms. The blanket’s temperature is the same as the mattress surface, providing uniform temperature around the body. This effectively doubles the heating and cooling efficiency.
   • Pricing: In the US, adding the blanket increases the price to $4,099. In the EU/UK, a UK Double size starts at £3,449 (on offer from £3,599).
3. Pod 5 Ultra: This is the most expensive and advanced version, including the Cover, Hub, Blanket, and an adjustable Base.
   • Key Features: Provides Immersive temperature control, elevation, and sound. It includes all features of the Plus model, plus the adjustable base that offers back pressure relief with zero-gravity elevation, snoring mitigation by slightly raising the head of the bed, and integrated surround-sound speakers for playing soundscapes, guided meditation, or audio alarms. The base is designed to fit within your existing bed frame or can be used as a standalone frame with an optional Leg Kit. The adjustable base and built-in speakers are new additions to the Pod 5 Ultra compared to the Pod 4 Ultra.
   • Pricing: The complete Pod 5 Ultra setup in the US starts from $6,099 for a queen size to $6,300 for a king or Cali king. In the EU/UK, prices begin at €6,599 for the large double size and go up to €6,699 for the Emperor size. Due to the added blanket, the Pod 5 Ultra is significantly more expensive than the equivalent Pod 4 Ultra in the EU.

Pod 5 vs. Competitors: Active Control vs. Wearables

There are no direct competitors to Eight Sleep.

The Eight Sleep Pod 5 fundamentally lacks a direct competitor because no other product combines smart, active temperature regulation with integrated, passive tracking.

Simple heating solutions, such as electric blankets, are not true alternatives. They offer basic heating only, lack cooling, and cannot provide the individualised, dual-zone temperature changes that automatically adapt to two different people’s sleep needs throughout the night.

The QS EMfit is the only other quality passive tracker. While accurate, its key deficiencies include the lack of temperature control and a user interface that is significantly less functional and user-friendly than the Eight Sleep app.

Wearable trackers, such as the Oura Ring and WHOOP MG, offer a clear trade-off: they provide continuous 24/7 wellness insights (Strain, Activity, Recovery) that extend beyond the bed. However, they do not control the sleep environment. The Pod 5 excels in controlling the thermal environment, which actively and directly improves sleep quality—the foundation from which all the most meaningful physiological insights (like stable RHR and HRV) are derived.

Eight Sleep Pod 5 – Is It Accurate?

The EightSleep Pod 5 is one of the most accurate consumer-grade sleep monitors on the market, and I use it as a reference test source when correlating HRV readings with those from other sleep devices. Our deep sleep test confirmed a correlation of r approx. -0.810 (strong negative) against WHOOP MG, establishing the Pod 5 as the most consistent and trustworthy tracker. Another reference-grade sleep monitor would be the Oura Ring. One advantage that a bed sensor has to deliver accurate readings is that your body position won’t impact the reading quality – lying on a wristwatch will affect accuracy.

Eightsleep detects Deep Sleep (N3), Light Sleep (N1/N2), and wakefulness well. However, every consumer-grade technology struggles to measure REM sleep accurately, and overall, no consumer-grade device will ever be more than 80% accurate compared to the industry gold standard, polysomnography.

EightSleep will utilise its overnight HRV averages to provide a market-leading assessment of your readiness and stress levels. It’s very good at this, and even though pro athletes use EightSleep, there is a slightly superior method, outlined here. However, its execution lacks the convenience of EightSleep’s passive data collection. EightSleep is WAY easier.

Deep Sleep Accuracy Test: Eight Sleep Best (60-85% Acc)

Correlation Summary:

• Oura vs. Whoop MG: r is approx. -0.161, n=30 (weak negative)
• Oura vs. Eight Sleep: r is approx. 0.145, n=30 (weak positive)
• Whoop MG vs. Eight Sleep: r is approx. -0.810, n=30 (strong negative)

Evaluation of the Best Tool to Measure Deep Sleep

• Oura: Weak correlations with Whoop MG and Eight Sleep, high variability (SD approx. 34.66), and a plausible but low mean (63.90 min) suggest inconsistency. Outliers (e.g., 15 min) may indicate underestimation or sensitivity issues.
• Whoop MG: Strong negative correlation with Eight Sleep (-0.810) and high mean (131.83 min) suggests potential overestimation, as values often exceed typical deep sleep ranges (60–120 min). Moderate variability (SD approx. 13.46) indicates reasonable consistency, but the negative correlation raises concerns about measurement alignment.
• Eight Sleep: Weak correlations with Oura but strong negative correlation with Whoop MG. Its mean (77.87 min) and range (55–107 min) align well with expected deep sleep durations, and the lowest variability (SD approx. 10.03) suggests high consistency.

Best Tool: Eight Sleep is likely the best tool for measuring nightly deep sleep. Its measurements are within the expected range for adults, it has the lowest variability, and its consistency suggests reliability (30 nights, one person). Whoop MG’s high values and strong negative correlation with Eight Sleep suggest potential overestimation or methodological differences. Oura’s high variability and weak correlations indicate less reliability. Without a clinical standard, Eight Sleep’s alignment with expected deep sleep durations and stable measurements makes it the most trustworthy.

EightSleep App

In mid-2025, EightSleep simplified its app. It’s easier to have a glance or make a quick change over and above what is handled automatically. The new app doesn’t look as good and has less detailed stats initially visible, probably in response to issues raised about the complexity of the previous version.

Here is the active control view. There is one for each side of the bed. It shows the current and target temperatures, plus an overview of the temperature plan for the night, which will be adjusted in real time. You can manually override temperature here or by tapping a small pad built into he mattress cover on each side of the bed.

The main stats screen summarises how good last night’s sleep was and what changes EightSleep made. In my case, the changes boosted Deep sleep by 5%. You can scroll down to see some of the key measures of your sleep, many of which can be tapped for more details. Here you can see my main Health Check is good with the 3 main aspects in their normal ranges. A late night resulted in a sleep pattern that was below my normal range.

Installation and maintenance

Compared to earlier pod versions, the current mattress cover can easily be put over your existing mattress within minutes. Priming the pod with water is easy (ideally, add some hydrogen peroxide to reduce mould over time). The tricky bits are:

• Ensure the pipe runs from the top of the mattress to the pod without excessively bending
• Ensure the bedside pod unit has space around it to vent air.

There is no regular maintenance per se. You may have to top up its small water tank once a year. The system can also be set to automatically prime itself each day, circulating water to prevent air bubbles. I used to have that running, but I have now turned it off.

What to watch out for: All generations of Eight Sleep require a separate bedside Hub connected to the mattress by small, flexible pipes. The Hub must have 2 inches of space to keep it cool, and the piping needs to be discreetly routed behind your bed to the centre of the headboard. Pod4 and Pod 5 utilise a significantly improved mattress cover that reduces installation time from several tens of minutes to just a couple of minutes – it’s easy and a one-time task.

EightSleep Pod 4 vs. Pod 5

The company still sells Pod 4 and is worth considering to save some money.

Despite what you might read elsewhere, the only real difference between pod 5 and pod 4 is the blanket and the new speaker in the Ultra model. Both have a reclining base option.

The earlier pod 3 has more fundamental differences. For example, it is much noisier and the temperature cannot be controlled by tapping the side of the bed..

Pod 4 or 5 are the ones you want buy.

Pricing & The Subscription Cost

A monthly subscription (Autopilot plan) is required for the first 12 months to utilise the Pod’s intelligent features, sleep history, preferences, and environmental factors to automatically adjust temperature throughout the night. It also provides sleep and health reports and continuous software updates. The subscription covers two users.

• Pricing for Autopilot Plans: Standard is £17/month (£199 billed annually), Enhanced is £25/month (£299 billed annually), and Elite is £33/month (£399 billed annually).
• Warranty: A 2-year limited warranty is included with an active Standard membership. An extended warranty for up to 5 years is available with active Enhanced or Elite memberships.

Autopilot: Justifying the Subscription Cost

The monthly Autopilot plan subscription is a significant ongoing cost that covers the tools that continuously adjust to real-time biometric data (HRV, sleep stage) and environmental factors (room temperature, weather). This is the unique feature that passive wearable trackers cannot copy. Without the subscription features Eight Sleep still provides analytics, but temperature control is manual.

The Ideal Buyer: Core, Plus, or Ultra?

Eight Sleep’s personalised temperature control is likely to increase anyone’s sleep quality. It’s suitable for singles and couples alike as both sides are personalised and controlled independently.

• Pod 5 Core (Best Value): Ideal Buyer: Individuals or couples needing precise, dual-zone temperature management. Additionally, suitable for menopausal hot flashes or for athletes who use cooling to enhance adaptation and monitor recovery with HRV tracking.
• Pod 5 Plus (Enhanced Cooling/Heating): If you live in a more extreme climate, the Plus model has twice the heating and cooling power to quickly achieve your ideal sleep temperature.
• Pod 5 Ultra (Sleep Apnea/Snoring Solution): Potentially life-changing for those impacted by chronic snoring or those managing mild obstructive sleep apnea symptoms. The adjustable base (included) is necessary to achieve head elevation for these benefits.

Take Out

Expensive. Excellent. Silent. I’ve used Eight Sleep for several years. It’s an expensive but excellent product. If optimising sleep through environmental control is your priority, the Pod 5 remains the category winner. The major positives are that you and your partner will likely get better sleep every night…

The major positives are that you and your partner will likely get better sleep every night, and each side of the bed adjusts separately based on your preferences and detected sleep stages. It’s a unique product that works. The sleep data it generates and uses throughout the night is accurate and on par with the best in the industry. If your partner snores, the 5 Plus model gently nudges them to change position, stopping the snoring without waking them or you.

I haven’t used the new blanket yet, and while I don’t doubt it works, I’m unconvinced about what it adds beyond the already excellent temperature regulation of the mattress. Similarly, the adjustable mattress is unnecessary unless you address one or both of your snoring issues.

Negatives include the subscription cost for the Autopilot features. Another negative, in my case, is that the pod doesn’t always handle ambient room temperature changes well as the seasons shift. That said, a quick tap-recalibration fixes the issue for a few months as it re-personalises your temperature profile.

I’ve reviewed a lot of fitness and wellness tech for over a decade, and Eight Sleep is one of my favourites (top 5!!)
