Original Leesa Mattress vs Sleep Number Classic Series

Leesa

Original Leesa Mattress Review Highlights

  • Impressive performance: The Original mattress is one of the highest-scoring mattresses that we’ve tested at the Mattress Advisor lab. With scores of 8.5/10 or higher in every category of our 14-point evaluation, you know you’re getting an all-around excellent bed. 
  • Sleeping position: With a medium-firm feel and a plush comfort layer, the flagship Leesa mattress works well for every sleep position
  • Pain relief: This mattress excels at properly supporting the spine and cushioning pressure points. Combined, this means a bed that helps soothe back pain as well as other body aches.  
  • Couples: People who share the bed typically sleep better when a mattress excels at motion isolation and edge support. The Leesa’s all-foam construction absorbs motion and is sturdy around the edges, so you can spread out and toss-and-turn without waking your partner.
Sleep Number c2

Classic Series Mattress Review Highlights

  • Value: The Classic Series are the least expensive Sleep Number beds that still boast all of their cutting edge technology. This includes SleepIQ sleep tracking technology, dual air adjustability, and Responsive Air technology. 
  • Couples: Separate air chambers on each side of the bed mean couples can choose their preferred firmness while sleeping side-by-side. It also limits motion transfer so you can sleep together peacefully. 
  • Firmness: Thin comfort layers paired with adjustable air chambers create one of the firmest and most responsive Sleep Number mattresses, great for back and stomach sleepers.

Compare the Construction

The Original Leesa mattress is a memory foam and polyfoam mattress whose medium-firm feel rates a 6 on the 1-10 firmness scale. The Sleep Number Classic beds have a similar firmness that ranges between a 5-7/10. While these are both medium-firm mattresses, their overall feel and sleeping experience differ substantially. 

The Leesa mattress has a plush 2” polyfoam top layer over a 2” contouring memory foam layer for incredible pressure relief and a moderate hugging sensation. The Classic beds have either a 2” or 3” polyfoam top layer that’s not quite as soft or conforming as the Leesa’s upper layers of foam. As a result, the Leesa is better for sleepers who like a soft, pillow-top-like surface and the Sleep Number for those who like a sturdier foam feel. 

The other big difference between these mattresses is their base layer. The Leesa uses support foam for exceptional stability, durability, and motion isolation. The Sleep Number Classic utilizes an adjustable air chamber support layer that’s dual-sided on larger mattress sizes. The air chambers allow you to find your perfect firmness and enjoy a different feel from that of your sleeping partner.

Compare the Cost

The flagship Leesa mattress has a similar price point to the least expensive Classic bed, the c2 smart bed. The c4 smart bed costs $600 more for a queen-size mattress.

Leesa Hybrid Mattress vs Sleep Number Performance Series

Leesa Hybrid Mattress Review Highlights

  • Outstanding performance: The Leesa Hybrid earned a 9.4/10 in the Mattress Advisor lab, the highest score any mattress has ever received! What this means is that the Hybrid excels across the board.
  • Perfect spine alignment: The Leesa Hybrid is one of very few beds that have earned a perfect 10/10 score for spinal alignment at our mattress lab. If you struggle with back or neck pain, the Hybrid may be just what you need for fewer aches and pains.  
  • Plush yet supportive: Few mattresses balance cushion and support the way that the Leesa Hybrid does. Over 1,000 individually encased coils deliver targeted relief while 3 foam layers balance softness, contouring, and support. The combination is great for side, stomach, and back sleepers.
  • Ideal for combo sleepers: Combination sleepers need a mattress that works well for all sleeping positions while being easy to move around on. The Leesa Hybrid fits the bill perfectly!

Performance Series Mattress Review Highlights

  • Pressure relief: The Performance Series beds have thick comfort foam layers for enhanced pressure relief, great for side sleepers and those who like a plush feel. 
  • Ideal firmness: Most sleepers prefer a medium or medium-firm mattress. With firmness options ranging from 4-7.5/10, these beds are ideal for the average sleeper.
  • Couples: With dual-sided air chambers and a variety of sizes designed for those who co-sleep, the Performance Series mattresses are excellent for couples who share the bed.  
  • Sleep tracking technology: The Performance beds are among the other Sleep Number mattresses with SleepIQ, a sleep tracking technology that gives you the data you need to fine tune your sleeping habits for optimal sleep and health.

Compare the Construction

The Leesa Hybrid is a memory foam hybrid mattress with a medium firmness that registers as a 5/10. The Sleep Number Performance Series consists of 3 mattresses with firmness ranging from 4-7.5/10, each with adjustable firmness. These beds have similar thicknesses, with the Leesa measuring 11” and the Performance beds 10”-11”.

Both of these mattresses have a similar thickness of comfort and transition foam atop their support layers. However, the Leesa hugs the body more closely thanks to a layer of conforming memory foam. They both work well for all sleeping positions thanks to the balance of cushion and support, but their feels are still quite different. 

The Leesa Hybrid has a supportive layer of innerspring coils that limit sagging and provide sufficient support for sleepers, no matter their body size. The springs create a slightly springy, responsive feel that makes it easy to move around and get comfortable in a new position. The Sleep Number’s adjustable air chamber support allows you to find your perfect firmness. However, it’s not as easy to move around on, so the Leesa is better for people who toss and turn.  

Compare the Cost

The Performance Series mattresses are substantially more expensive than the Leesa Hybrid.

  • Eco-friendly: The Legend is one of the best hybrid mattresses for the environment and your health. It’s made using materials like organic cotton, organic wool, and upcycled steel. 
  • Luxury: Lying on the Leesa Legend is a luxury experience. With cushy polyfoam, cradling memory foam, and responsive coils, you can feel that the Legend is built for optimal comfort and longevity.  
  • Firmness: The Leesa Legend has a medium-firm feel that’s perfect for the average sleeper.

Innovation Series Mattress Review Highlights

  • Extra cushion: The Innovation Series has the thickest foam layers of any Sleep Number mattress, making it the best choice for those who want a soft adjustable air mattress
  • Cooling: Innovative materials regulate temperature, making these beds excellent for people who sleep hot. 
  • Luxury: The Innovation line contains the most luxurious Sleep Number mattresses. With firmness that ranges from soft to medium-firm, the plush feel and adjustable support will make your bedroom feel like a high-end resort. 

Compare the Construction

The Leesa Legend and Sleep Number Innovation Series mattresses are luxury beds. The Legend is a 6-layer hybrid mattress with a medium-firm feel, while the Innovation Series are foam airbeds with firmnesses that range from soft to medium-firm

What these two beds share in common is that they have generous foam layers atop their supportive base layers. These plush layers of foam deliver exceptional pressure relief, ideal for side sleepers

However, only the Legend has zoned support, with extra cushion at the shoulders and hips and greater support along the body’s trunk. This combination of give and support is perfect for stomach sleepers who may experience sagging as a result of the Innovation’s thick foam layers. And with two layers of supportive innerspring coils, the Legend is better for most heavy sleepers. 

Of course, the Sleep Number Innovation mattresses have adjustable and dual-sided firmness. This versatility is great for couples and anyone who isn’t sure what mattress firmness they desire. It’s also great for people with changing firmness needs, such as pregnant women or elderly folks.  

Compare the Cost

While both the Legend and Innovation are luxury mattresses, the Innovation Series has a much steeper price tag.

Leesa Studio Mattress vs Sleep Number Value Beds

Studio by Leesa

Leesa Studio Mattress Review Highlights

  • Cost: The Studio is Leesa’s most affordable bed. And as Leesa is an online mattress company known for reasonable prices, this means the Studio is within the budget of most mattress shoppers. 
  • Ideal balance: With a soft comfort layer and responsive medium-firm feel, the Studio is a great mattress for the average sleeper.
  • Pain relief: The Studio earned a 9/10 in our spine alignment test. By supporting a healthy spine, the Studio is a good choice for people with back pain.  
Sleep Number s1

Value Beds Review Highlights

  • Dual adjustability: Couples who have different firmness preferences can each get what they need for a good night’s rest thanks to dual-sided air chambers.  
  • Cost: Sleep Number Value beds are an affordable option for shoppers who want adjustable firmness at a budget-friendly price. 
  • Zoned-support: Both Sleep Number Value mattresses have zoned foam layers for optimal cushion and support. This makes the Value beds good for every sleeping position. 

Compare the Construction

The Leesa Studio mattress and Sleep Number Value beds are the most affordable mattress lines for these two companies. The Studio is a 3-layer memory foam mattress with a medium-firm feel, and the Sleep Number Value beds are adjustable air mattresses with firmnesses ranging from medium to medium-firm

Thanks to both of these mattresses having relatively thin comfort layers, we recommend them for people that weigh less than 230 pounds. Lightweight side sleepers will find the Sleep Number s3 Value bed a more comfortable mattress thanks to their 7-zoned PlushFit comfort layer. Leesa’s top layer is a memory foam that offers more contouring than cushion, so it works best for back and side sleepers

The Value mattresses sleep cooler than the Leesa Studio. This is thanks to the cool air chamber in the Value beds along with these mattresses having thinner comfort foam layers than the Studio mattress. 

Because the Value mattresses have dual adjustability and sleep tracking technology, they’re a better fit for shoppers who want a smart bed.  

Compare the Cost

The Leesa Studio is less expensive than either of the Sleep Number Value beds.

Leesa Studio Value Beds
Twin $599 $599-$1,099
Twin XL $649 $699-$1,199
Full $699 $799-$1,299
Queen $799 $999-$1,499
King $999 $1,499-$2,099
California King $999 N/A

Mattress Sizes

Sleep Number mattresses come in a wider range of sizes as well as thicknesses. Thicker mattresses are better for heavier people, while split beds work exceptionally well for couples who use an adjustable bed frame. Only opt for a thin mattress (around 10” or thinner) if you’re smaller and don’t require a lot of cushion.

Breaking Down the Trial Periods

While both mattresses come with a 100-night sleep trial, Leesa’s terms are more generous. With Leesa, you can truly try out your new mattress risk-free. There is no charge for shipping, and there is no fee for returns. Sleep Number charges $199 for shipping and mattress setup, which is not refundable if you return your mattress. Additionally, they charge a $199 return shipping fee when you return your bed. 

Explaining the Warranties

The Leesa warranty is 10 years, while Sleep Number’s warranty is 15 years. However, Leesa’s warranty is more generous than Sleep Number’s. During the duration of the Leesa warranty, Leesa will repair or replace your mattress with zero deductible if there’s a covered defect. Sleep Number’s warranty only covers the full cost of replacement during the first year, and SleepIQ technology is not covered by the warranty.

Decision Time: Which Is the Best Mattress Brand?

Leesa and Sleep Number are two well-loved mattress brands that work for every sleeping position and body size. Leesa’s medium-firm mattresses all have a plush surface, and the balanced feel works exceptionally well for the average sleeper. Sleep Number beds are best for people who want a smart bed and would enjoy adjustable firmness settings. And while both companies are great for couples, Sleep Number’s dual-adjustability and split sizes make it the ideal company for couples.
