The Enhanced membership ($25 per month, $299 annually) extends the warranty to five years, which matters with such an investment. Even though I haven’t experienced hardware issues yet, the system relies on pumps, tubing, and sensors running every night. That introduces more failure points than traditional mattresses, and consumers have reported warranty replacements for various issues over the years. Once coverage ends, replacing the hardware could be expensive. The new Elite tier ($33 per month, $399 annually) also includes a five-year warranty and Health Check.

Beyond the ongoing costs, there are also privacy considerations; cloud dependency issues, which I explain below; and questions about how much access a company should have to your bedroom. Last year, security researchers discovered vulnerabilities in Eight Sleep’s firmware, including back doors that could permit remote access and enable unauthorized users to run arbitrary code and transmit user data to Amazon Web Services (AWS). This also means that Eight Sleep engineers can know when you’re asleep, whether two people are sharing the bed, and when the bed is empty. “Imagine your ex works for Eight Sleep,” Dylan Ayrey and Jake King, cofounders at cybersecurity company Truffle Security, wrote in a 2025 blog post.

Eight Sleep has since updated its security policies, clarifying that customer support can only access a user’s Pod remotely with explicit consent and while the user is physically present with the device.

Finally, because the Pod depends on cloud connectivity, disruptions can affect functionality. During an AWS outage in late 2025, some users momentarily lost temperature regulation and adjustable-base features. Eight Sleep has since introduced Backup Mode to reduce the impact of connectivity failures, but it doesn’t guarantee that similar problems won’t happen again.

The Pod 5 is the best temperature-regulating sleep tracker I’ve tested. But between the mandatory subscription, privacy compromises, and cloud reliance, the gap between what it costs and what it demands you accept remains wider than ideal. If you’re already an Eight Sleep member, the trade-in program makes sense. If you’re a newcomer, you should know exactly what you’re buying.

As for me? I’m going to keep using it. That’s the truth.

More Eight Sleep Accessories

I haven’t tested these add-ons, but if you’re curious, here’s a rundown of the available accessories.

Base for $1,999: Eight Sleep’s adjustable 3-inch base sits under your mattress and auto-adjusts elevation to reduce snoring and relieve pressure points. It’s also designed with an integrated speaker for soundscapes, white noise, and guided meditations. It’s compatible with most bed frames or can stand alone with Eight Sleep’s Leg Kit ($99).

Blanket for $999: The hydro-powered blanket syncs with the Pod Cover and mirrors its dual-zone temperature capabilities. Eight Sleep also sells an optional Duvet Cover ($199) and Pod Sheet Set (starting at $189), both made of machine-washable modal and custom-designed to fit your Pod Cover and Blanket.

Air Pillow for $299: This memory foam pillow is designed with a temperature-regulating gel and an air-ventilation system to dissipate heat and increase breathability.

Pillow Cover for $999: This pillow cover syncs with the Pod Cover to control head and neck temperature throughout the night. For independent temperature regulation from the Pod Cover, you’d have to connect the Pillow Cover to a separate Hub.

Pod Protector for $119: Made from moisture-wicking nylon and polyester with a waterproof laminate, this cover is meant to protect the Pod from allergens, spills, and other grime.

Mattress starting at $1,899: Eight Sleep sells its own five-layer mattress that pairs with the Pod Cover.
