Sleep Number offers several collections tailored to different needs and budgets:

Sleep Number’s greatest promise is individual comfort, and this is where it shows its strengths.
You can adjust the firmness level (your “sleep number”) on each side from 0 (soft) to 100 (very firm). This is ideal for couples who prefer different levels of support.
Higher-quality models detect movement and automatically adjust support when you change position while you sleep – as if by magic, only real.
Integrated biometric sensors track your vital signs and deliver a daily SleepIQ score via the mobile app. You can see how lifestyle factors (like eating late or exercising) affect your sleep and make adjustments accordingly.
Depending on the model, the construction may include:
All beds are CertiPUR-US® certified and made in the USA.
Sleep Number offers free delivery on select models, but most Smart Beds require white glove delivery, which includes:
