Amerisleep and Sleep Number are luxury mattress companies with high customer satisfaction ratings. While they each offer a wide range of high-quality mattresses, their construction and feel could not be more different.

The Amerisleep AS1 mattress is a firm mattress made from 2 layers of memory foam. The Sleep Number Innovation Series includes 3 mattresses with generous foam layers atop adjustable air chambers. These mattresses range from soft to medium-firm.
The AS1 mattress has just 2” of cushy memory foam, compared with 6-7” of pressure-relieving foam found inside the Innovation Series beds. Thanks to a more generous comfort layer with a luxurious pillow top mattress feel, the Innovation series is better for side sleepers. Both mattresses work well for stomach and back sleepers, with the AS1 a better fit for people who prefer a firm feel and the Innovation for those that like something with a bit more cushion.
Because of the AS1’s minimal comfort layers and sturdy polyfoam base, it offers better edge support than the Sleep Number mattresses. Both beds offer good motion isolation, thanks to the all-foam construction of the AS1 and the dual air chambers in the Innovation Series. These attributes make both mattresses excellent for couples who share the bed. Because the Innovation Series has dual-sided firmness, it’s better for couples who have different firmness preferences.
The AS1 is Amerisleep’s most affordable model, while the Innovation Series comprises the highest-end Sleep Number mattresses. As such, the price difference between these beds is vast, with the Innovation Series mattresses costing many times that of the AS1 mattress.
|Amerisleep AS1||Innovation Series|
|Split Cal King||N/A||$4,899-$6,399|
|FlexTop Cal King||N/A||$4,899-$6,399|
The Amerisleep AS2 mattress is an all-foam mattress, with the Sleep Number Memory Foam bed is a memory foam and air bed hybrid. Both the Amerisleep AS2 and Sleep Number Memory Foam beds use generous layers of foam to ensure adequate comfort and pressure relief. Five inches of cooling memory foam and supportive polyfoam create beds that work well for every body size.
What really sets these mattresses apart is their firmness levels. The Sleep Number Memory Foam bed ranges in firmness from medium-soft to medium-firm, while the AS2 is a firm mattress. Side sleepers do better on a softer mattress, while back and stomach sleepers may enjoy either mattress type, it just depends on personal firmness preference.
While both of these beds do an excellent job minimizing motion transfer, making them good mattresses for couples, only the Sleep Number bed has dual-sided firmness. Couples who tend to prefer different mattresses can sleep together comfortably on the Sleep Number Memory Foam mattress.
The Sleep Number Memory Foam mattress costs 2-3 times the price of the Amerisleep AS2.

The Amerisleep AS3 is a memory foam mattress whose medium firmness rates a 6 on the 1-10 firmness scale. Sleep Number’s Classic mattresses have a similar feel, with their firmnesses ranging from 5 to 7 out of 10.
While they both have similar firmnesses, the AS3 has 5” of plush comfort and transition foam, while the Sleep Number has only 2-3”. The thicker comfort foam means the AS3 is going to deliver a closer hugging feel with superior pressure relief, while the Classic is firmer without much sinkage. As such, the AS3 is better for side sleepers and those who like a cushiony feel to their mattress, and the Classic beds are best for those who don’t desire a plush feel.
The Classic mattresses have cutting edge technology that the AS3 doesn’t. The adjustable firmness allows you to find the right feel for you, and with dual air chambers, couples can customize their sleeping experience. This mattress also comes with SleepIQ, sleep tracking technology that gives you the tools to help improve your sleep.
Sleep Number’s Classic Series mattresses are less expensive than Amerisleep’s AS3 model, costing $400 less for a queen-size mattress.

The Amerisleep A4 and Performance Series are luxury mattresses with generous comfort layers. Each boasts 4-5” of foam that conforms to the body, making them great options for those who like the feeling of sinking into their mattress—particularly side sleepers of all body sizes. The A4 has a top layer of memory foam that molds even closer to the body than the soft polyfoam comfort layer of the Performance beds.
The A4 mattress is an all-foam mattress whose foams come together for a medium-soft feel. Thanks to the air chambers that control the firmness of the 3 Performance Series mattresses, each of these beds can be as soft as the A4 or as firm as a medium-firm bed. This adjustability makes the Performance beds ideal for couples with different firmness preferences as well as people who aren’t sure what firmness they prefer. The firmer feel is also better for most back and stomach sleepers.
Because the Amerisleep A4 mattress is a bed-in-a-box memory foam bed, it has a moderate off-gassing odor when first unboxed that you won’t experience with the Performance Series beds. Rest assured that this odor is temporary and will fade within a few days.
Both the AS4 and Performance Series are luxury mattresses with luxury price tags. However, the Amerisleep is going to save you some money when compared to a Performance Series mattress.

The Amerisleep AS5 is an ultra-soft mattress. It boasts 3 layers of memory foam and polyfoam for an incredibly luxurious feel. You’ll definitely feel like you’re sleeping “in” rather than “on” the AS5.
The Sleep Number Value Beds are much different. They each have a minimal comfort layer of between 1-½ and 2-½ inches atop adjustable air chambers. This foam layer is zoned, helping to cushion the hips and shoulders while supporting the head and lumbar region.
Because both mattresses have zoned support, they’re excellent at keeping the spine properly aligned. Outside of this similarity, their feels and benefits are vastly different. Go with the AS5 for pressure relief and a deep hugging feel. Opt for the Sleep Number Value mattresses if you want a medium-firm to firm feel with minimal pressure relief, or if you and your partner have different firmness needs.
Side sleepers are going to prefer the AS5 and stomach sleepers the Sleep Number Value mattress. Back sleepers are better served by beds that offer a balance between plush contouring and firm support.
The AS5 is Amerisleep’s most luxurious mattress, while the Value Beds are Sleep Number’s budget-friendly mattress line. The Amerisleep costs around twice that of a Sleep Number Value bed.

While both the Amerisleep and Sleep Number mattresses come in the same standard mattress sizes, Sleep Number offers a variety of sizes created for couples that Amerisleep does not offer.
The FlexTop beds are specifically designed for use with an adjustable base. You’ll also notice that some of the Sleep Number beds are very thick. These mattresses are excellent for plus-size sleepers.

Shipping varies substantially between Amerisleep and Sleep Number.
Amerisleep ships for free within the contiguous United States. As a bed-in-a-box mattress brand, the Amerisleep mattress arrives compressed into a tall, thin box. You must wait between a few hours to a few days for the mattress to fully expand and lose any off-gassing odor.
Sleep Number mattresses are delivered full-size with the Comfort Service Home Delivery. This service includes:
Comfort Service Home Delivery costs $199-$249, depending on where you live. They ship everywhere in the USA except for Hawaii.
Both mattresses come with a 100-night sleep trial, but the terms are different; Amerisleep’s return policy is more generous. Amerisleep offers full refunds with zero fees during this time. Sleep Number charges a $199 return shipping fee, and they do not refund the original Comfort Service Home Delivery fee.
When you buy a new mattress from Amerisleep, it’s backed with a generous 20-year warranty. Sleep Number’s warranty is 15-years, and the coverage quickly lessens over that period of time. Overall, the Amerisleep warranty is better than Sleep Number’s.
Amerisleep and Sleep Number carry a wide range of mattresses that work for every sleeping position. While both companies offer soft and luxurious mattresses perfect for side sleepers, only Amerisleep has a bed firm enough for those who need an extra-firm bed.
If you’re someone who wants to find your perfect firmness level, track your sleeping habits, or sleep with a partner who typically prefers a different mattress, Sleep Number is an excellent option. But if you’d rather enjoy the simplicity of a high-quality, luxury memory foam mattress, Amerisleep is one of the best brands out there.
While both mattress brands offer a 100-night sleep trial, only Amerisleep’s trial is truly risk free thanks to their free shipping and returns. You must pay for initial shipping and return shipping if you return your new Sleep Number mattress.
