We tested the AS3 and Nectar mattresses across 14 categories in our mattress lab. You can see how they did in the following comparison chart.
|Motion Transfer Test||8.5||8.75|
|Edge Support Test||9||8|

|Spinal Alignment Test||7.5||8.25|
|Customer Service Score||8.5||9|
|Social Impact Score||5||4|
As you review the Mattress Advisor scores for these mattresses, consider your sleeping position. Back sleepers fare well on firm mattresses, and stomach sleepers do best on medium-firm beds that keep their spine aligned. The Nectar scored higher for spinal alignment, so it’s the better option for these two sleeping positions.
Side sleepers need extra pressure relief to cushion their shoulders and hips. Again, the Nectar scored slightly higher in this category.
If you’re a combo sleeper, look at the scores for responsiveness. This category has the widest score gap between the two mattresses. Nectar received a score of 8.5/10, and AS3 earned 7/10. That makes the Nectar the better option for sleepers who expect to move around a lot at night.
Do you sleep with a partner? Do you live in a warm climate or tend to get hot at night? Then pay extra attention to categories related to your sleep environment.
Couples—or anyone who anticipates sleeping with a partner—need a bed with good motion isolation if they want an undisrupted night’s sleep. Both mattresses scored well in this category, but the AS3 did a fraction better.
If you get hot while you sleep, look at the scores for cooling. The Amerisleep AS3 and Nectar mattresses scored just above average for cooling, and again, the AS3 received a slightly higher score.
At the end of the day, both of these mattresses will give you a good night’s sleep. They each have a medium feel that works for the average sleeper, plus effective cooling features. They also both provide adequate pressure relief. Still, we recommend the Nectar for combo sleepers and budget shoppers and the AS3 for couples.
