Bottom Line

Sleep Number has been revolutionizing air mattresses for over three decades. They've designed Smart Beds that put you in control of your sleep. The m7 model is the only bed that combines cooling memory foam with all the benefits Sleep Number is known for, including SleepIQ® technology. Try the m7 for 100 nights risk-free, today!

Get Sleep Number m7 if...

  • You love memory foam. The m7 is the only Sleep Number model with a 5" combination of cooling memory foam and comfort layers. If you enjoy the contouring, slow-responsive nature of memory foam, this bed is for you.
  • You sleep with a partner. The m7 comes with built-in dual-sided adjustability, so you and your partner can choose your own firmness levels.
  • You sleep hot. The temperature balancing sleep surface absorbs excess heat and releases it as you cool so you sleep comfortable all night long.

Skip Sleep Number m7 if...

  • You want to keep things simple. The m7 model requires the use of either the Sleep IQ® mobile app or Sleep Number remote to control the firmness level. If you aren't particularly tech saavy, this might not be the right choice for you.
  • You're on a budget. While not the most expensive Sleep Number model available, it certainly isn't cheap. The addition of memory foam and cooling capabilities make this a great investment for some! If you're looking to spend $1000 or less, this isn't the right mattress for you.

Pros

  • Dual-sided adjustability, ideal for couples who prefer different firmness levels
  • Effortlessly responds to your body and automatically adjusts accordingly
  • Only Sleep Number model with a thick layer of memory foam

Cons

  • Bed requires assembly
  • A bit pricey, definitely an investment

Firmness/Feel/Comfort

The m7 Smart Bed is adjustable to your preferred firmness level with Sleep Number settings ranging from 1 (softest) to 100 (firmest).

The m7 model comes with a 4" cooling memory foam layer atop a 1" gel-infused comfort layer for superior pressure relieving qualities. The air chambers allow you to adjust the firmness levels to your desired setting (whether that's sink-in soft or no-pushback firm).

Construction Key Points

  • The Sleep Number m7 is 11" tall.
  • Cover - A blend of rayon and polypropylene fabrics with a soft fiberfill material sewn directly into the cover for nice, breathable comfort.
  • Comfort Layer - 4" of cooling memory foam combined with a 1" gel-infused comfort layer provides luxurious pressure-relieving support.
  • Air Chambers - Depending on the size, the m7 is built with either single or dual-sided air chambers. The chambers are connected to a 4-foot long pump (hidden within the mattress) that inflates or deflates your mattress based on your specifications.

Support & Motion Isolation

The 4" thick layer of cooling memory foam allows you to sink into the bed for superior pressure point relief. It's also one of the best materials at absorbing movement. Memory foam combined with two separate air chambers, one on each side of the mattress, means the m7 performs incredibly well at isolating motion. Any motion stays on individual sides of the bed.

Reasons to Buy Sleep Number m7

  1. If you sleep with a partner, this bed is a perfect solution. The Queen size and up comes with 2 air chambers (one on each side) that allows you and your partner to adjust your side to your personal comfort level.
  2. This is a great choice for people who tend to sleep hot. The Sleep Number m7 keeps quite cool as it's constructed with a thick layer of cooling memory foam. Plus, its temperature balancing technology ensures heat isn't trapped in the mattress.
  3. If you love the slow-responsiveness of memory foam, the m7 is perfect for you. It's the only Sleep Number model that contains a thick layer of memory foam so you can sink-in and feel "hugged."
