Sleep Number

Sleep Number is a bedding company that sells bed, mattresses, and various bedding products. However, the company is best known for its signature product, the Sleep Number bed, which comes with an adjustable air mattress and various add-ons like a smart system, adjustable bases, and different types of comfort foam mattress pads.

Saatva Solaire vs Sleep Number: Similarities and Differences

Though the Solaire and Sleep Number i8 Smart Bed are both adjustable air beds, they are made with different materials and have different overall feels. Before I get into the details about each of these mattresses, I’m going to summarize their similarities and differences, and share which sleepers I think they’re best for.

Main Similarities 

  • Both beds are adjustable and have a range of firmness settings. They both use air chambers that inflate to create a firmer feel, and deflate for a softer feel.
  • Both mattresses are made from high-quality materials and have a luxurious overall feel.
  • Both beds have memory foam layers that offer some nice pressure relief.
  • Both beds have low motion transfer, which means you’re unlikely to feel a partner or pet rolling around on the other side of the bed.

Saatva Solaire Side SleepingSide sleepers will probably prefer setting below 35 on the Solaire for great pressure relief.

Main Differences 

  • The Sleep Number is significantly more expensive than the Saatva Solaire.
  • The Sleep Number has 20 firmness settings, while the Solaire has 50. 
  • The Sleep Number is a smart bed, and will give you a SleepIQ® score and recommendations for how to improve your sleep.
  • The Sleep Number automatically responds to your movements throughout the night, while the Saatva is manually controlled.

Which is Better for You?

Depending on your body weight, preferred sleeping position, and whether or not you sleep with a partner, one of these mattresses might better suit your needs. Take a look at some of my recommendations below. 

  • Since both mattresses have such a wide range of firmness options, I’d recommend them for most sleeping positions. I recommend side sleepers go with a softer firmness setting, back sleepers go with a medium-firm setting, and stomach sleepers go with a firm setting.
  • I think both beds are great for couples. They have individual air chambers on each side, so each person can adjust the mattress to their individual preference.
  • If you’re looking for a bed that tells you what’s the best firmness level for you, I’d recommend the Sleep Number bed. Not only does it automatically respond to your movements and adjust firmness accordingly, but your SleepIQ® score should tell you how to improve your sleep.
  • If you prefer to manually control your bed and don’t like the idea of the mattress working automatically, then I’d recommend the Solaire.
  • Since both of these beds use air chambers that can deflate throughout the night, they might not be the best fits for heavier sleepers (those over 250 lbs). If that’s you, I’d recommend checking out one of our best mattresses for heavy people.

Saatva Solaire and Sleep Number Mattress Feel Comparison

Now that you have an idea about the basics of each of these mattresses, let’s discuss their overall feels. To give you the best idea of feel, I’m going to discuss the mattresses’ firmness levels, motion transfer, edge support, and pressure relieving abilities. 

Saatva Solaire

The Solaire is an adjustable bed, and has 50 firmness levels, so it’s not quite possible to give it an exact firmness rating. However, I’d say that in those 50 levels, it can range from a super soft 4 on the firmness scale to an ultra firm 8 (with 1 being the softest and 10 the firmest on the firmness scale). This means that the Solaire works for pretty much any sleeping position! I’d recommend side sleepers go with a setting in the 20s, back sleepers opt for something between 30 and 35, and stomach sleepers go with a setting in between 40 and 50. Additionally, the Solaire has air chambers on both sides of the mattress, so two people can adjust their own firmness levels. This is great news for couples, since you might be a side sleeper, but your partner might prefer lying on their stomach — the two of you need very different firmness levels!

The Solaire also performed really well on our motion transfer test. This test measures how much movement travels from one side of the bed to the other. I could hardly feel any movement from one side of the bed on the other, and this is another great perk for couples, who shouldn’t feel distubed by a restless partner.

Lastly, I’d like to mention that the Solaire has impressive edge support for an all-foam air mattress. The Solaire was designed with a high density poly foam layer surrounding its air chambers and this makes for some fantastic edge support that will add durability to the mattress. In my opinion, Saatva mattresses that use this poly foam edge support layer have some of the best edge support in the game.

Sleep Number 360 i8

Like the Solaire, the Sleep Number has adjustable firmness levels — 20 to be exact, with the higher settings feeling firmer and the lower settings feeling softer. I would say that in those 20 settings it ranges in firmness from about a 5 on the firmness scale to an 8. So whether you prefer to sleep on your side, stomach, or back, you should find a setting to suit your needs. Additionally, multiple settings means you can target different issues. If you’re worried about lumbar support you can put your mattress on a firmer setting; if pressure relief at sensitive pressure points is your main concern you can opt for a softer setting.

The Sleep Number 360 i8 has also received acclaim from testers for having excellent motion isolation. Sleepers said that even if their partner had a very different sleep number from them, they didn’t notice their movements throughout the night. 

Finally, I think the Sleep Number has fairly good edge support. I think you could comfortably sleep on the side of the mattress without feeling like you were going to roll right off. However, the Saatva definitely wins in terms of edge support.

Comparing Saatva Solaire and Sleep Number Prices

Of course, before buying a new mattress you’ll want to consider the price. Both the Solaire and the Sleep Number are luxury mattresses, so they don’t come cheap. However, the Solaire is more affordable than the Sleep Number. Take a look at the pricing chart below that shows the cost for each size. Be sure to visit our Saatva coupon page or Sleep Number coupon page for all the latest discounts.

Comparing Saatva Solaire and Sleep Number Mattress Materials

Both the Solaire and Sleep Number are adjustable air beds, so their materials are going to look quite a bit different than any hybrid mattress or memory foam mattress you’ve seen before. However, both brands do have some big differences in what they use in their constructions, so take a look at my breakdown below.


  • Cover – The Solare has an organic cotton cover that is quilted with a bit of memory foam which should offer a little pressure relief.
  • Comfort Layer – Below the cover is a top layer of gel-infused memory foam, which should offer some nice contouring and sleeps cooler than traditional memory foam. This foam is also CertiPUR-US® Certified, which means it’s free from harmful chemicals and heavy metals.
  • Transition Layer – Next up is a layer of all-natural Talalay latex, which adds some bounce and support and transitions the sleeper onto the air chambers. There’s also a moisture barrier right below this layer, which should help prevent condensation. 
  • Support Layer – The main event: the Solaire’s vulcanized air chambers! These chambers inflate and deflate using a remote control and in sizes queen and up there are two air chambers, so each side of the bed can be individually adjusted.
  • Base Layer – Last is a layer of high-density poly foam. This layer also surrounds the air chambers, which adds some fantastic edge support to this mattress.

Saatva Solaire ConstructionShowing the materials used in the layers of the Saatva Solaire

Sleep Number

  • Cover – The Sleep number’s cover is made from a temperature-balancing material called Smart 3D fabric that absorbs body heat and releases it as you cool.
  • Comfort layer – Next up is a 6-inch layer of comfort foam made from two different types of foam that offers some nice cushioning and pressure relief.
  • Support – This layer is made from the Sleep Number’s air chambers. If you get a bed size full or larger, you’ll get two air chambers and experience Sleep Number’s DualAir technology. The air chambers hook up to a hose and pump so you can manually adjust them, but they also automatically adjust to your movements and weight
  • Base- Note*** The Sleep Number base is sold separately. Sleep Number recommends using their FlexFit™ Adjustable Base, which allows you to raise the head or foot of the mattress so you can easily read or watch television in bed. However, this base is quite pricey. They also recommend the far cheaper Sleep Number Modular Base or a basic platform base. Sleep Number recommends you don’t use a slatted bed frame or traditional box spring with this mattress.
