A smart mattress is a bed with built-in sensors that track sleep metrics like movement, heart rate, and breathing, and some models adjust firmness or temperature automatically.
Smart mattresses promise better sleep by collecting data on how you rest, then using that information to create a more comfortable environment. Sleep Number describes its smart beds as using embedded SleepIQ sensors that monitor heart rate, breathing rate, movement, and sleep duration. Eight Sleep calls its Pod an intelligent bed cooling system that tracks sleep while monitoring heart rate, HRV, and temperature continuously. The core idea is the same: your mattress learns how you sleep and adapts.
How Do Smart Mattresses Work?
Smart mattresses use sensors built directly into the bed to collect physiological data while you sleep. These sensors detect subtle movements from your breathing and heartbeat, then feed that information through a connected app that generates sleep reports and insights.
What separates a basic smart mattress from a truly intelligent one is what it does with that data:
- Sleep tracking: Most models measure duration, movement, and sleep stages, then score your night in an app.
- Firmness adjustment: Sleep Number’s air-chamber design lets you change firmness on each side with a remote or app, and the bed can suggest settings based on your data.
- Temperature control: Eight Sleep’s Pod uses water-filled tubes to heat or cool each side of the bed independently, so one partner can sleep warmer while the other stays cool.
The sensors never touch you directly — they read your body’s motion through the mattress surface, which means tracking happens automatically without wearing anything. Data appears in the companion app each morning, showing time asleep, restlessness, heart rate trends, and breathing patterns.
Which Brands Make Smart Mattresses?
Sleep Number and Eight Sleep are the two most recognized names in the category, though they take different approaches. Sleep Number offers a dozen mattresses in its current lineup, according to Wirecutter’s review, with smart features including under-bed lighting, head and foot adjustability, and foot warming on select models.
Eight Sleep’s Pod series focuses almost entirely on temperature. You install the Pod cover over your existing mattress, connect it to a hub that heats and cools water, and control each side’s temperature through the app. It also tracks your sleep and continuously monitors heart rate, HRV, and temperature — making it a good fit for couples who argue over the thermostat.
The Sleep Foundation’s guide to best smart mattresses notes that features vary widely by model. Cooling and heating, firmness adjustment, and foot warming are options on specific products, not universal across every smart bed. Before buying, decide which features actually matter to you, then confirm the model you’re considering includes them.
Are Smart Mattresses Worth It?
Smart mattresses cost considerably more than standard beds, so the value depends on what you want from it. If you sleep alone or with a partner and struggle with temperature disagreements, Eight Sleep’s dual-zone cooling provides a concrete benefit you cannot get from a regular mattress. If you want adjustable firmness that changes as your needs evolve, Sleep Number’s air chambers deliver that flexibility. If you simply want to track sleep quality, a wearable or a standalone sleep monitor under your sheet costs far less than a full smart mattress.
One common mistake is confusing a smart mattress with a smart bed base or a sleep-monitoring pad. Some products track sleep without being a mattress at all. Another is assuming every smart mattress includes every smart feature — basic models may track sleep but offer no temperature control or adjustability. Review the spec sheet carefully rather than assuming the word “smart” means fully loaded.
Setup and support also matter. Sleep Number provides a dedicated help center with a smart bed user guide, and its products are sold through official stores rather than unauthorized third-party retailers. Eight Sleep also operates a U.S.-facing site, though buyers should confirm compatibility with their foundation and bed size before ordering.

FAQs
Do I need a special bed frame for a smart mattress?
Most smart mattresses work with standard foundations, but some models require specific bases. Sleep Number sells adjustable bases that pair with its mattresses, while Eight Sleep’s Pod cover fits over your existing mattress and works with most foundations. Always check the manufacturer’s compatibility requirements before purchasing, since some features like head and foot adjustability need a compatible adjustable base.
Can a smart mattress replace a sleep tracker watch?
A smart mattress tracks movement, breathing, and heart rate through built-in sensors, which means you do not need to wear anything to bed. This makes it more convenient than a wrist tracker, though the data is slightly less precise than devices worn on your body. For most people, the mattress data is sufficient to understand sleep patterns and identify improvement opportunities.
Are smart mattresses covered by warranty?
Yes, major brands back their smart mattresses with warranties, though terms vary by manufacturer and model. Sleep Number provides warranty coverage through its support center, and the electronics components are typically covered separately from the mattress surface itself. Review the warranty document before purchase to understand what is covered and for how long, particularly for sensors and cooling systems that may have different coverage periods.
