Sleep Number Mattresses
Sleep Number (formerly Select Comfort) has manufactured adjustable air mattresses in Minneapolis since 1987. The brand's signature technology is the DualAir™ system: two independent air chambers in a split-king or queen mattress, each adjustable from firmness 0 (softest) to 100 (firmest) via a remote or smartphone app. This makes Sleep Number uniquely suited for couples with dramatically different firmness preferences. Modern Sleep Number 360 series models add biometric sleep tracking — monitoring heart rate, respiratory rate, and movement without wearables — and automatic firmness adjustments based on detected sleep position changes.

Sleep Number — Frequently Asked Questions
What is a Sleep Number setting?
The Sleep Number setting (0–100) represents your personal firmness preference on the air scale. A lower number is softer; a higher number is firmer. The 'smart' series automatically adjusts within a range based on your movement and position.
Is Sleep Number good for couples?
Yes — Sleep Number is purpose-built for couples with different firmness preferences. In a queen, each side adjusts independently (though not to extreme differences without a split king).
Does Sleep Number require electricity?
Yes. Sleep Number mattresses require the base/pump unit to be plugged in to adjust firmness. Power outages will leave the mattress at its last setting.
Is Sleep Number worth it?
For couples with significantly different firmness needs or data-driven sleepers who want biometric tracking without a wearable, Sleep Number offers a unique value. For simpler needs, a high-quality hybrid at lower cost may be more appropriate.
Where can I buy Sleep Number?
Sleep Number is sold exclusively through Sleep Number retail stores. There are over 600 locations across the US.
