Compare Feel and Inside Layers

The Saatva and Amerisleep mattresses are vastly different when it comes to their construction, and with it, the sleeping experiences that they offer. Let’s take a look at what sets these two beds apart. 

The Saatva Classic is a memory foam hybrid bed made from 5 layers of foam, innerspring coils, and organic cotton. It comes in 3 different firmness options, with the plush soft measuring a 3 on the 1-10 firmness scale, the luxury firm a 6, and the firm an 8. There are even 2 thickness profiles, an 11.5” and 14.5.”

Thanks to the variable mattress options, the Saatva truly works for every sleeping position and body size. The below layers vary in thickness and composition to create a customizable sleeping experience. 

The Amerisleep AS3 mattress is a memory foam mattress crafted from 3 layers of foam. Its slow-response memory foam top layer deeply cradles the body, perfect for those who like the feel of sleeping “in” rather than “on” their mattress. 

Its medium firmness level is a 6 on the 1-10 firmness scale, an ideal feel for both back and side sleepers. In comparison to other all-foam beds, the Amerisleep AS3 sleeps cool thanks to cooling technology found in both the cover and the foam layers.

Motion Transfer

If you share your bed, you’ve probably been woken up by your partner moving around. When it happens once or twice, it’s no big deal. But if you or your partner are woken up on a regular basis, you really need to get a mattress that better isolates movement. 

The Amerisleep AS3 earned an impressive 8.75/10 in our motion isolation test. Its all-foam construction means you and your partner can switch positions and get in and out of bed without waking one another. The Saatva Classic didn’t perform as well, with its generous innerspring layers delivering just a bit too much reverberation. With impressive motion absorption properties, the Amerisleep may be a better choice for couples. 

Spine Alignment

Good posture is just as important when sleeping as when awake. The thing is, you don’t have any control over it. It’s the quality of your mattress that determines your back’s alignment at night.

We test every mattress for spinal alignment, and the Saatva Classic earned a perfect 10/10. While Amerisleep AS3 scored well at 8.25/10, those who struggle with joint or back pain may be better served by Saatva’s superior alignment abilities. 

Sleep Trial

Because you buy these mattresses online, it’s important to have time at home to test them out and ensure that they’re the right fit. Both the Amerisleep AS3 and Saatva Classic mattresses come with a sleep trial, but differences between the trial terms may help you decide which mattress to choose.

Amerisleep offers a 100-night trial period with free returns. When combined with free shipping, there is zero financial risk to trying this bed at home. Saatva’s sleep trial is significantly longer, giving you 365 nights to test drive your new mattress. However, they do charge a $99 transportation fee, so you would be out a small amount of money if you find out that it isn’t the best bed for you.

Verdict: Which Is the Best Mattress?

After our evaluation, the Saatva Classic came in on top, earning an 8.9/10 compared to the Amerisleep AS3’s 8.4/10. Saatva’s exceptional edge support, alignment, cooling, and durability make it an excellent luxury hybrid mattress. And with variable firmness options and thicknesses, the Saatva Classic works for every body shape and sleeping position. 

But with Amerisleep’s luxury memory foam feel, it’s a great choice for side sleepers of every weight. It also boasts impressive motion isolating properties, a valuable attribute for those who share the bed with a spouse, child, or pet.

Whichever one you choose, know you’re backed with generous trial periods that let you try out your new mattress in the comfort of your home.
