Mattress summary: This hybrid model is Amerisleep's most popular mattress and is available in an all-foam version as well as a hybrid. Our testers for the Amerisleep AS3 hybrid mattress review found the medium feel extremely comfortable for side and back sleepers. Motion isolation and edge support were also excellent on the AS3 Hybrid. The free Refresh Cover currently included with this hybrid mattress is scientifically engineered to convert your natural body heat into far infrared energy – a type of energy that studies have shown to increase blood circulation, making it a great option for those who are looking for fast muscle recovery. It's important to note that our testers found this a little too soft for stomach sleepers and suggest heavier sleepers might also want a firmer surface. In the current mattress sales, A queen is now $1,499 (was $1,949).

Benefits: 100-night sleep trial | 20-year warranty | Free shipping and returns

Price history: The Memorial Day mattress sale this year saw the Amerisleep AS3 Hybrid discounted by $450. It's currently $50 cheaper at $1,499 (was $1,949) for a queen size, so we think now is a great time to snap up this pressure relieving, fiberglass-free mattress.

Do side sleepers need a soft mattress?

To relieve pressure on the shoulders, hips and knees, experts recommend side sleepers sleep on a soft or medium-firm mattress. Ideally, the best mattresses for side sleepers will have cushioning that allows your shoulders and hips to sink in slightly. This will promote proper spinal alignment and support the neck and head, reducing the risk of back pain. That said, a mattress that is too soft will have the opposite effect. A side sleeper’s spine should stay neutral rather than sinking in too much. 

Also beware how body weight influences the type of mattress you need as a side sleeper. Heavier people will need a firmer mattress than lighter people.
