Let's give you a quick run down of just what the Eight Sleep Pod 4 Ultra is. The Pod 4 Ultra consists of three things: a mattress cover, a thin bed base, and a control hub. Together, these components can control the temperature and angle of your bed while tracking your health data overnight to provide personalized sleep reports.
The Pod 4 Ultra is the latest release from innovative sleep brand Eight Sleep, enhancing the previous design while adding a bed base for adjustable positioning. The precise temperature controls makes the Pod 4 Ultra ideal for anyone who struggles with night sweats, overheating, or hot flashes, while the new bed base can alleviate aches and pains.
To access these features, you will have to pay a premium price. The Pod 4 Ultra pricing starts at $4,029 and there's also a small subscription fee required to access the linked Autopilot app. The Memorial Day sale takes $150 off all sizes of the Pod 4 Ultra which might not sound like a massive saving, but it's among the best mattress sales we've seen from Eight Sleep.

Eight Sleep Pod 4 Ultra smart mattress cover: price, trial & warranty
The Eight Sleep Pod 4 Ultra smart cover and base is a premium sleep setup, with prices starting at $4,049. While there's no getting around the fact this is an investment purchase, the price is in-line with the best smart beds and mattresses.
On top of the initial cost, you will also have to pay a monthly fee to the Eight Sleep Autopilot app. There are two subscription plans, and each covers two users: a Standard plan is $15 a month, and the Enhanced plan is $24 a month. A subscription is required for the first twelve months. You can let it lapse after that, you won't be able to access the Pod 4 Ultra's full range of features.
The Pod 4 Ultra comes with free shipping and returns, plus a 30-night mattress trial. Considering the overall cost of the Pod 4 Ultra, we might expect a longer trial (some of the best luxury mattresses come with a full year to test the bed). The warranty is also pretty short: two years if you choose the Standard Autopilot plan and five years if you opt for Enhanced.
Here is the full price list:
- Queen MSRP: $4,049
- King MSRP: $4,249
- California king MSRP: $4,249
Eight Sleep Pod 4 Ultra smart mattress cover: design & materials
- Comes with a cooling cover, adjustable base, and a control Pod
- Cover and base can be controlled via the hub or your smartphone
- Optional mattress and leg extension kit
There are three key areas to the Ultra Pod 4 system: the smart cooling cover, the adjustable base, and the control Pod. Each piece works together to create a cooler, more comfortable sleep experience.
The cover is a water-based cooling and heating system with dual temperature zones. You and your partner can adjust each side of the bed to suit your exact needs, while the smart tracker will learn preferences for each person.
The Pod 4 Ultra has an enhanced cooling system, designed to reach optimum temperatures in even extreme conditions. As a smart system, it's also capable of adjusting the temperature throughout the night to meet your changing needs. There are sensors across the cover that can track your sleep and health data, which you can access via the Autopilot app.
Sitting between your mattress and your bed frame, the smart base can incline at both the head and the feet to achieve a neutral angle similar to the zero gravity position. It's also fitted with snore mitigation technology. When the sleep tracker detects snoring, the head of the bed raises to open the airways.
Finally, you have the Pod itself. This is a small rectangular device that can sit by the bed or slip beneath the frame. The Pod essentially controls the cover, dictating what temperature based on the information from the sleep tracker.
The Pod 4 Ultra system doesn't come with a mattress but Eight Sleep promises the cover will fit on your current mattress. Alternatively, you can add an Eight Sleep mattress to your order. You also have the option of adding a leg kit, which will transform your bed base into a bed frame.
Eight Sleep Pod 4 Ultra smart mattress cover: support & comfort
- Precise temperature regulation with smart adjustments
- Pressure relieving adjustable sleep positions
- Firmness, motion isolation, and edge support depends on mattress beneath
Normally when discussing the support and comfort of a mattress, we talk abut how it the bed feels to sleep on. That's not really relevant here. There's also not much point in discussing edge support or motion isolation as, again, it will depend on the mattress beneath. The Pod 4 Ultra is slimmer and more flexible than ever, meaning it shouldn't change the feel of your bed.
Let's instead dive in with temperature regulation, an area where the Eight Sleep Pod 4 Ultra excels. The water based system allows you to adjust the temperature to suit your needs, while the sleep tracker ensures the cover can maintain this temperature overnight. Designed to work in even extreme temperatures, the Pod 4 Ultra should keep you comfortable no matter what the weather might be up to.
The Eight Sleep system doesn't offer the changeable firmness you get with some smart beds (like the Sleep Number i8 Smart Mattress), but the adjustable base does allow you to tweak the support. By raising the head and the feet you can improve pressure relief and you can customize the position to suit your needs.
And with the Eight Sleep Pod 4 Ultra, you'll also get some features that don't exactly come standard with a mattress, including in-depth sleep tracking. It also acts as an alarm, with subtle vibrations and thermal changes gradually rousing you. Woken up too early or need to adjust the temperature during the night? You don't have to grab your phone – you can control the cover via the Pod base.
