Best Sleep Tracking Pads
Under-mattress sleep tracking pads are the right choice for people who can't or won't wear a wearable overnight. The two picks below cover the price spectrum: Withings Sleep is the $130 entry point (sleep stages + snore detection + heart rate, nothing more), and the Eight Sleep Pod 4 Cover is the $2,449 premium tier (sleep tracking integrated with active cooling and AI auto-adjustments). For most users, Withings is the right starting point.

Frequently Asked Questions
Are sleep tracking pads as accurate as wearables?
Slightly behind, but close. Withings Sleep matches top-tier smartwatches for sleep stage accuracy within 5–8%, and is more accurate than many fitness trackers because it picks up subtle body movement and respiratory data that wrist-worn devices miss. The Eight Sleep Pod 4 cover is even more accurate because it combines a denser sensor array with full-body coverage. Both pads have one limitation versus wearables: they only track the sleeper on their side of the bed.
Do I need two pads if I sleep with a partner?
For Withings Sleep, yes — each pad tracks the sleeper above it. The Eight Sleep Pod cover is full-bed and tracks both sleepers independently using its dual-zone sensor array. If you want personalized data for both partners without buying two devices, Eight Sleep is the only single-purchase option.
Can a sleep mat detect sleep apnea?
Withings sells a separate model called the Sleep Analyzer (currently primarily distributed outside the US) with CE-marked sleep apnea detection. The standard Withings Sleep mat sold on Amazon US does not include the apnea screening feature — it detects snoring, but not apnea events. For US shoppers who want apnea screening from a non-wearable, the Apple Watch Series 10 and Galaxy Watch 7 are currently the better path.
