Eight Sleep Pod 4 vs Pod 5 Ultra+: which smart mattress cover should you buy?
Eight Sleep is at the forefront of smart bed innovation, employing world-first technology to beat your sleep woes, be they night sweats, snoring or back pain.
While the Eight Sleep Pod 4 has reigned as the best smart bed on the market for the last year, the new Pod 5 Ultra+ comes with an adjustable bed base, advanced sleep tracking, temperature control and in-bed surround sound. Yes, we're blown away too.
The Pod 5 Ultra+ may be discounted in current mattress sales but it's still thousands of dollars above the Pod 4. Ahead, we'll explore whether the Pod 5 Ultra+ is worth the extra expense, or if the Pod 4 is enough for your sleep needs.
Eight Sleep Pod 4 smart mattress cover: from $2,449 at Eight SleepWith independent temperature regulation, sleep tracking and a vibration and thermal alarm, the Eight Sleep Pod 4 is a high tech addition to your sleep routine. It's not discounted this Memorial Day but at $2,449 for a queen, it is still far cheaper than the new Pod 5 range.
Eight Sleep Pod 5 Ultra+ smart mattress cover and base: from $5,049 $4,699 at Eight SleepThe Pod 5 Ultra+ does everything the Pod 4 does, plus it comes with an adjustable bed base, surround sound and snoring mitigation. It'll cost you almost double, but a Memorial Day deal takes $350 off MSRP which is one of the biggest discounts we've seen from Eight Sleep. This brings a queen to $4,699 (was $5,049).

Packed with game-changing technology, the Eight Sleep Pod 4 and Eight Sleep Pod 5 Ultra+ are both premium buys, costing at least $1,000 more than even the best mattresses you can buy online right now.
As the simpler system, the Pod 4 is the most affordable of the two, with prices starting at $2,449 for a full and $2,649 for a queen. The Pod 4 is available in full, queen, king and California king sizes, none of which are currently discounted.
The Pod 5 Ultra+ overhauls smart features offered by the Pod 4 and adds a whole new dimension to the Eight Sleep system – an adjustable bed base. This upgrade inevitably brings a bigger price tag, with prices starting at $5,049 for a queen at MSRP. King and California king sizes are also available.
The good news is current Eight Sleep mattress sales knock $200 off all sizes of the Pod 5 Ultra+. This brings a queen size to $4,849, a rare discount from the sleep tech brand.
As well as the initial expense, you do have to pay a subscription to use the Eight Sleep Autopilot app. A Standard subscription costs $17 a month, while the Enhanced subscription is $25 a month and Elite (needed for Eight Sleep's new health check feature) is $33 a month. A subscription covers two users.
For such a pricey purchase, the benefits are disappointing. There's only a 30-night sleep trial, which is significantly less than we see from most sleep brands (some beds even come with a 365-night mattress trial). The warranty period is also short: two years with the Standard subscription plan, five years if you upgrade to Enhanced or Elite.
The Eight Sleep Pod 4 is a water-based smart cooling system consisting of a mattress cover and a control Hub. The pipe-lined mattress cover fits over your existing mattress like a fitted sheet while the control hub sits next to your bed.
The bedside hub contains a water tank that controls your in-bed temperature and sleep tracking, vibrating sensors are laced throughout the black fabric mattress cover. Data is recorded during the night, which you can access via the connected Autopilot app in the morning, and here's a tap control panel on the side of the mattress to operate the vibration alarm.
The Eight Sleep Pod 5 Ultra+ comes with the same cover and Hub as the Pod 4, with the addition of a smart adjustable bed base.
This isn't a bed base in the traditional sense. It's only three inches tall and sits between your mattress and your current bed frame, allowing you to adjust the position of your sleep surface. (Although you can add a leg extension kit, to transform the Ultra into a full bed base.)
There's also the option to double up on temperature regulation with a hydro-powered blanket on the Pod 5 Ultra+. This means you can sleep in a cocoon with finely-tuned thermal controls.
On the other hand, primarily a smart mattress cover, the Pod 4 simply adds a temperature-regulating, sleep-tracking layer to your existing mattress.
While a mattress isn't included as standard with the Pod 4 or Pod 5 Ultra+, you can add one to your order. But both pods are compatible with any mattress of the same size. You can simply fit it over your existing mattress or shop our best memory foam mattress and best hybrid mattress guides if you're after an all-new sleep set up.
Temperature regulation is at the core of the Eight Sleep system. The Pod 4 offers dual-side climate control, enabling you to heat up or cool down (between 13°C and 44°C) your side of the bed regardless of your partner's sleep temperature preferences and external climes.
Meanwhile, sensors will track your body temperature through the night and adjust to keep you at the best temperature for sleeping. This personalized, active temperature control earns the Pod 4 a spot in our best cooling mattress guide.
Both pods offer this temperature regulation on the back while you sleep. However, there is the option to add a hydro-powered blanket (for an extra $1,000 now) to the Pod 5 Ultra+.
This blanket syncs with the mattress cover's temperature on each side of the bed to create a fully immersive temperature experience.
Both smart mattress systems feature the reliable sleep tracking built by Eight Sleep's AI-powered algorithm. This means sensors in the mattress cover will track your sleep biometrics — including your over night heart rate, HRV, sleep stages and sleep latency — and produce nightly sleep reports.
It also produces a sleep scores to help you measure how well you sleep, and identify how lifestyle choices (like drinking alcohol or exercising late at night) impact your sleep quality.
While these sleep tracking sensors are uniform in each pod, of course, the Pod 5 Ultra+ includes new innovations too. An additional AI algorithm in the Pod 5 Ultra+ is capable of detecting fever. Picking up anomalies in your overnight heart rate and respiration, the Pod 5 Ultra+ will alert you via the Eight Sleep app if you are likely to fall sick.
Do note, you need Eight Sleep's Elite subscription to access this clinical-grade health check feature, costing $33/month.
Both the Pod 4 and Pod 5 Ultra+ have a gentle thermal, vibration alarm feature that replaces a blaring audio alarm. Thanks to the automatic climate control system in each pod, they gradually heat up in the morning to suppress your body's melatonin production.
The bed will then vibrate at your desired wake up time, gradually pulling you from sleep at the end of a sleep cycle rather than jolting you awake with a loud sound. This more natural wake up call reduces sleep inertia, helping you wake up with more energy.
As a humble mattress cover, the Pod 4 cannot adjust the position of your bed. However the Pod 5 Ultra+ includes an adjustable smart bed base, enabling you to raise the head and foot position of your bed.
This addition means you can customize your sleep set up and sit up comfortably in bed while reading or relaxing. Plus you can snooze in a zero gravity position, which is recommended for taking pressure off the back and joints. When paired with a top-rated mattress for back pain, the Pod 5 Ultra+ is sure to help you eliminate aches and pains to sleep comfortably.
This bed base also responds to your movements through the night to keep you fully supported. Meanwhile, sensors pick up snoring and the head position adjusts to open airways for easier, quieter breathing.
Ever thought we'd see the day your bed sung you a lullaby? Well, we're here. A new feature in the Pod 5 Ultra+ is surround sound. Yes, that means your bed plays sleep sounds while you drift off — great news for the 38% of Americans who struggle to sleep in silence, according to Talker Research.
Eight Sleep have a library of soundscapes to help you sleep, alongside non-sleep deep rest sounds delivered by Stanford University neuroscientist Dr. Andrew Huberman.
✅ You want a smart bed primarily for sleep tracking: The Pod 4 is laced with reliable sleep tracking sensors so you can track your ZZZs without wearables. Though you must forego the illness prediction feature with the Pod 4.
✅ You're on a tighter budget: The Pod 4 is still an investment smart bed but a queen size is $2,050 cheaper than the Pod 5 Ultra+ right now.
✅ You're happy with the feel of your mattress: The Pod 4 makes minimal difference to the comfort and support of your existing mattress without elevating any part of your bed.
✅ You have aches and pains: The Eight Sleep adjustable base included with the Pod 5 Ultra+ allows you to raise your head and feet. This curved 'neutral' position reduces pressure placed on the lumbar region for fewer aches and pains. And it's customizable, so you can adjust the angle to suit your personal sleep style.
✅ Snoring keeps you awake: The Pod 5 Ultra+ has specialist sensors to detect snoring. If it does detect noisy ZZZs, the bed base raises the head position to open airways. This helps you breath and minimizes noise.
✅ You can't fall asleep in silence: A key innovation with the Pod 5 Ultra+ is its built-in speakers offering in-bed surround sound. With a library of sleep sounds at your fingertips, you're sure to find a track to lull you to sleep.

I'm a sleep tech tester and the product I swear by for falling asleep fast is $26.99 in Amazon sale
As a sleep tech writer, I've spent the last 10 months searching the market for, and testing, the latest snooze-improving innovations. This has included gadgets and gizmos from smart sleep masks and sleep headbands to sleep trackers, top-rated sunrise alarm clocks and this year's best smart beds. But there's only one gadget I absolutely can't sleep without: a red light clip that attaches to my book. Dutifully obeying our sleep editor's advice around following a nighttime routine for better sleep, reading a few pages in the evening has become non-negotiable for me, and this clip light completes my bedtime routine. In current sleep sales, you can save 10% on the Szokled reading light clip at Amazon. This nudges the price from $29.99 to $26.99 — a small price to pay for a device that can help you cut out tossing and turning and fall asleep fast. And even better, you may be offered a 15% off coupon that takes the price down even further. Szokled Red Light Clip: was $29.99 now $26.99 at AmazonThe Szokled clip light has two modes: red light and warm light. The red light is ideal for pre-bedtime reading, protecting the eyes and bolstering your ability to fall asleep fast. While the warm light can create a cosy atmosphere any time of day. It comes with a timer, meaning the light will automatically turn off after you fall asleep, helping you snooze peacefully while saving energy. Amazon promises this red light clip has a 10-hour battery life and it's equipped with a USB-C port for convenient charging. Watch out for a 15% off coupon when you order! Red light exposure positively influences sleep onset, sleep duration and overall sleep efficiency by stimulating the production of melatonin, the all-important sleep-inducing hormone. Melatonin is responsible for making us feel sleepy. While bright white light suppresses this hormone, warm red light prompts the brain, specifically the pineal gland, to release it. So if you already have one of the best mattresses but you're still not getting enough sleep, a shortage of melatonin could be to blame. In fact, light is a key circadian cue and you can regulate your circadian rhythm with carefully-timed light exposure. Specifically, evening red light exposure and morning sunlight exposure helps your body get used to producing sleep-wake hormones at the right time of day so you fall asleep fast at night and wake up refreshed in the morning. What I really love about a red light clip is that it's lightweight and portable enough to take with me wherever I go. I stay away from home one night a week for work, and packing up my other sleep tech, namely my beloved Eight Sleep Pod 4 and Hatch sunrise alarm clock, wouldn't be so practical. Therefore, I rely on a red light clip to help me unwind in unfamiliar environments, and after six months of using it it's yet to fail me. I also recommend using a red light LED face mask as part of your bedtime routine if you're looking for a gadget that can help you wind down at night while taking care of your skin.

Tempur-Pedic Tempur-Neck Pillow review 2025: Soothing neck support for side and back sleepers
The Tempur-Neck stands out from most other bed pillows on the market thanks to its unique design, which follows the natural curve of the neck and head. It's designed for back and side sleepers in particular, and comes in three sizes (small, medium and large) so you can pick the one best suited to your sleep position and body shape. Type: Tempur material (foam)Best for: Side and back sleepersSizes: Small (20" x 12.5" x 3.5"), medium (20" x 12.5" x 4") and large (20" x 12.5" x 4.75")Trial: N/AWarranty: 5-year limitedPrice: From $119 MSRP at Tempur-Pedic Tempur-Pedic mattresses are hugely popular, and the brand has used its signature pressure-relieving Tempur-Material (essentially high-end memory foam), which is both firm yet comfortable, in this best-selling pillow. We felt it strikes the right balance between sturdy support and cushioning comfort — which can help minimize the risk of exacerbating any existing conditions. As a combination sleeper, our tester found the Tempur-Neck to be the most comfortable when lying on her back. This way, her neck felt instant pressure relief that she described as being akin what she'd feel after a neck massage at a spa. She slept on the pillow for over two weeks and was comfortable all night long, never waking up with aches or pains. She even felt that it reduced any muscle tension she experienced. In addition to sleeping on it during the testing period, we also put the Tempur-Neck pillow through other performance tests (more on that below) in which it scored well. Overall, we rate the Tempur-Neck a 4 out of 5 stars considering the various parameters like comfort, support, temperature regulation and durability. Keep reading to find out more… In terms of the cost, Tempur-Pedic pillows are not exactly budget purchases in comparison to some of the other best pillows out there. At MSRP, the Tempur-Neck retails at $119 for a small size, $129 for a medium and $159 for a large, and is in the mid-range bracket for the brand (their most expensive pillow, the Tempur-Cloud Dual Cooling Pillow, starts from $199 for queen when at full price). However, you can snag excellent deals on the pillow during Tempur-Pedic sales. These don't come around as regularly as you'll find at other sleep brands, but when they do, particularly around events like Black Friday and Memorial Day, you'll find that you could save up to 50% or more. The brand also occasionally runs 'buy one get one free' sales, which is the perfect time to stock up on two of your favorite Tempur-Pedic pillows, letting you sleep better for less. Two pillows that are similar to the Tempur-Neck in terms of design and functionality are the Nest Bedding Easy Breather (from $119) and the Sleep Number NaturalFit Ultimate (from $169 to $199) — the first at a similar set of price points and the second coming in a little more expensive. Tempur-Neck pillow: from $119 at Tempur-PedicThe Tempur-Neck pillow is available in three sizes: small, medium and large. A small is priced at $119, a medium at $129 and a large pillow is $159. This price includes a 5-year warranty and free shipping. While the Tempur-Neck is currently full price for a single pillow, you will get 30% off when you buy two. The Tempur-Neck is comprised of a single block of the brand's signature Tempur-Material. Described as having an 'extra firm feel' it is designed specifically for back and side sleepers, delivering pressure relief and relaxing your muscles while still keeping them supported. Unlike regular bed pillows, you don't have to spend your time and effort adjusting the Tempur-Neck to contour your neck and shoulders, since its design follows the natural curvature of your neck and head. As such, it's designed to always give solid support to your neck, without ever compromising on neutral spinal alignment, whether you're sleeping on your side or your back. You can choose between the three sizes, and Tempur-Pedic even provide a handy chart and instructions on the pillow's product page so you can find the ideal Tempur-Neck for your body type. The Tempur-Material is encased in a hypoallergenic knit cover made from 100% polyester, and handily it's both removable and machine washable. Hot sleeper? You have the option of upgrading your Tempur-Neck to include cooling technology, in the form of heat-wicking cooling yarns woven into the breathable cover. This costs $20, but if sleeping hot is a big problem for you we'd recommend a dedicated cooling pillow such as the Casper Hybrid with Snow Technology. That's the basics covered, so now let's take a closer look at how the Tempur-Neck fared across a range of specific performance parameters. This will help you make an informed decision on whether the Tempur-Neck will work for your sleeping style and needs. The Tempur-Neck is one of the few pillows we've found that does not require any additional steps to be set up fully. It arrives in a fuss-free cardboard box, wrapped in plastic film. You don't have to wait for it expand or adjust the loft or firmness by adding or removing fill. Simply tear the plastic off and it's all ready to be slept on. Score: 5 out of 5 I found the Tempur-Neck largely delivered on what it claims. I'm a combination sleeper (side and back) and I specifically loved the instant pressure relief of the foam, which mimics the soothing relaxation of a neck massage or spa. It is on the firmer side and hence is suitable for anyone who needs that extra sturdy support to keep their neck aligned or to reduce the risk of worsening their aches or pains. To test its comfort and support, we put it through a sink-in test by placing a kettlebell weighing 10lb (roughly the average weight of an adult head) on the pillow and leaving it for 5 minutes. As soon as we removed the kettlebell, the foam sprung right back up without even a dent to show that a weight had been placed on it. I also found the Tempur-Neck to be most comfortable for back sleeping since this truly gave my neck and shoulders the feeling that tension was melting away. Since I tend to prefer a pillow with a softer feel and do not particularly suffer from neck aches or shoulder pains, I found the curved design to be slightly distracting after a week. Similarly, if you're someone who wants a pillow that conforms to your neck and head, giving you a cradling effect (like you're sleeping on a cloud), the Tempur-Neck might not work as an everyday pillow. Score: 4 out of 5 Apart from the optional cooling upgrade, the Tempur-Neck doesn't include any cooling features. Since it is made from a type of memory foam (which is known to trap heat), we expected it to cause overheating, but this never happened while testing the Tempur-Neck, although it should be noted that the reviewer is not a hot-sleeper. I was sleeping on the Emma Hybrid Airgrid mattress and used an ordinary department store microfiber duvet during the Tempur-Neck testing period. The knit cover which wraps the Tempur-Neck, however, is not a light breathable material of the type you might find on other pillows. If you're a hot sleeper, you'd be advised to opt for the cooling upgrade or to go for the Tempur-Cloud Dual Cooling pillow, which comes in a breathable cotton cover with cooling gel on either side. Score: 4 out of 5 A pillow may be comfy enough to sleep on but is it easy to clean? This is why we consider maintenance and durability to be key factors when judging the performance of a pillow. Tempur-Pedic is a popular mattress and bedding brand in the US and one of the reasons why it's so well-regarded is its consistent quality. Compared with other memory foam pillows, the Tempur-Neck does not sag or require any fluffing to maintain its shape, comfort and support. Score: 5 out of 5 As per Tempur-Pedic's care guidelines, only the outer cover is removable and can be washed and dried on a cold setting. Air-drying is recommended. Tempur-Pedic also suggests that you should avoid over-drying it or using chlorine or harsh products for cleaning. Score: 4 out of 5 The Tempur-Pedic Tempur-Neck definitely lives up to the expectations. Finding a pillow that strikes the perfect balance of comfort and support is a tricky task for those struggling with neck pains or shoulder aches, and the last thing you need is a pillow that's either too soft or too firm and increases the risk of worsening the pain. If this sounds familiar to you, we believe that Tempur-Neck would be a good choice thanks to its ergonomic curved design and it's firm but instantly pressure relieving Tempur-material. While it's not one of Tempur's most affordable pillows, it sits around the middle of the Tempur-Pedic price range. Temperature control clearly isn't the Tempur-Neck's priority, and this is surely where it falls down compared with similarly-designed pillows such as the Nest Bedding Easy Breather and the Sleep Number NaturaFit Ultimate. The curved shape and the extra firmness also makes it an unsuitable option for stomach sleepers who require a low-loft model or one with a customizable fill like the Coop Home Goods Original pillow. ✅You suffer from neck pains or aches: The Tempur-Neck provides the right combination of cushioning and firm support to soothe any aches or pains. ✅You're a back or side sleeper: The ergonomic design follows the natural curve of the neck and is therefore perfect for side and back sleepers. ✅You need instant pressure relief for your neck: The Tempur-Material used in the pillow gives you instant relaxation which melts away the built-up tension in your neck and shoulder muscles. ❌You prefer a softer pillow: Tempur-Neck is the firmest Tempur-Pedic pillow and its cushioning won't appeal to sleepers who need a fluffy or plush model. ❌You need a more affordable pillow: Tempur-Pedic pillows are not exactly cheap compared to more budget-friendly options in the market. ❌No sleep trial included: Unlike most brands, Tempur-Pedic does not provide a sleep trial or returns for its pillows. Extra benefits are limited to a 5-year warranty and free shipping. 1. Nest Bedding Easy Breather Side Sleeper pillow: was $119 from $99 at Nest BeddingThis pillow with a similar curved design as the Tempur-Neck, is perfect for side sleepers who like a more softer feel to their headrest. Crafted from a blend of CertiPUR-US certified foam and polyester fiber, the Easy Breather provides plush comfort and contouring in addition to a breathable knit cotton cover for cool sleep (read the full review on the Nest Bedding Easy Breather Side Sleeper pillow for more details). You can now get this at $20 off which takes the price down from $119 to just $99. Extra benefits include a 2-year warranty and 30 night sleep trial. 2. Sleep Number NaturalFit Ultimate Pillow: was $189.99 from $151.99 at Sleep NumberThe NaturalFit is an adjustable pillow with removable fill inserts to suit your sleeping preference. The natural down and latex blend is a dream combination, ideal for anyone who like plush comfort and responsive support (read the full review on the Sleep Number NaturalFit Ultimate pillow for more details). It also comes in a breathable cotton cover preventing any overheating or night sweats (in addition to naturally temperature regulating down and latex). You can grab this now at 20% off, reducing the price of a standard pillow from $189.99 to $151.99, while a king is priced at $175.99 (was $219.99). 3. Beckham Hotel Collection Pillows: was $79.99 from $59.99 at AmazonNeed a simpler pillow which suits all sleeping styles and those prone to overheat during the night? The Beckham Hotel Collection crafted from down-alternative fiber impressed our reviewer who said it provides 5-star luxury comfort within a budget (read the Beckham Hotel Collection Pillow review to know more). It is also a great budget purchase (and hence the top affordable choice in our pillow guide) since you're paying for not one but two pillows. There's currently 25% off, which means a set of queen pillows is now $59.99 (was $79.99).
