The Smart Mattress

A mattress that cools, heats, and tracks your sleep — then adjusts automatically so you don't have to. Dual-zone climate control lets each side find its own perfect temperature.

  • Cools to 55°F or heats to 110°F — both sides independent
  • Tracks heart rate, HRV, sleep phases & snoring nightly
  • Wakes you naturally with vibration & thermal alarms

What makes it intelligent

Three layers of engineering work together inside a single mattress.

Dual-zone climate

Active cooling and heating woven through the mattress, with each side controlled independently from 55°F to 110°F.

Sleep sensing

Invisible sensors read your heart rate, HRV, breathing, and movement every night — no wearables required.

The app & Autopilot

Nightly sleep and health insights, plus automatic adjustments that learn your patterns.

Common questions

Yes. The Cover sits on top of your mattress like a fitted sheet and works with virtually any mattress up to 13 inches thick. There's nothing to replace.

Absolutely. Each side of the bed is an independent zone, so one person can sleep cool while the other stays warm.

Sleep on the Core at home for 30 nights. If it isn't for you, start a return for a full refund — shipping both ways is on us.

The Hub is engineered to run quietly beside your bed. Most people find it blends into the background within the first night.

No. You can adjust temperature with tap controls right on the Cover. The app adds tracking, scheduling, and Autopilot's automatic adjustments.
