At this point, you probably have an idea of which mattress is better for you. We’d like to help that reasoning along by highlighting these mattresses’ performances on pressure relief, spinal alignment, and responsiveness.
The Leesa scored 0.75 points better than the AS3 for pressure relief. It does a slightly better job of lifting stress off of your pressure points, making it the better option for side sleepers. The Leesa also outperformed the AS3 by 0.75 points for spinal alignment. This is an important factor for all sleeping positions, but particularly stomach sleepers.
Combo sleepers should pay attention to the scores for responsiveness, which measure how well a mattress responds to your changes in position. Again, the Leesa scored higher, this time by 1.5 points.
We’d like to point out that neither of these mattresses scored poorly in any of these areas, so you’re set for success with both beds.
Your particular sleep environment plays a role in which mattress will feel the most comfortable. Couples often look for a mattress that will reduce disruptions from their sleeping partners. Both the Leesa and AS3 scored high on motion isolation, so both are good picks.
Additionally, hot sleepers or those in warm climates look for mattresses that sleep cool. While the Leesa marginally outperformed the AS3 in this category, both mattresses feature effective cooling technologies.
While we love both of these all-foam mattresses, the Leesa outperformed the Amerisleep AS3 in all but two categories. Not only is it one Mattress Advisor’s highest rated mattresses, it’s also more affordable than the AS3. AS3 is the bed for you if you’re looking for the long-term insurance the 20-year warranty can provide.
