Who Is The Amerisleep AS3 Mattress  Good For?

The Amerisleep AS3 is ideal for sleepers who prefer a medium-firm mattress with a responsive feel and the cooling benefits of memory foam. The combination of its two layers makes it an especially good fit for side sleepers, who are less likely to be bothered by pressure points that may occur when lying on top of memory foam.

This means that they will have more support and less pressure with good airflow through their system, preventing or minimizing things like night sweats and hot flashes.

The mattress is perfect for:

  • All-type sleepers who weigh over 130 pounds.
  • Couples, especially those who are looking for lower motion transfer.

Is The Amerisleep AS3 Mattress  Good For Side Sleepers?

The firm, tactile core of the Amerisleep AS3 helps it to give great support for side sleepers. By distributing their weight more evenly over the mattress, side sleepers are less likely to experience pressure points when moving around in their sleep.

Better support can also help reduce snoring in this position. Side sleepers tend to want more firmness in their mattresses than back sleepers, so this is an especially good option for them.

Is The Amerisleep AS3 Mattress Good For Back Sleepers?

While the Amerisleep AS3 is firm enough to provide effective support for most back sleepers, its quilted top does have less sinkage than most foam mattresses not made of memory foam. This means that its edges will be firmer than those of other mattresses, which can make it more challenging to move around if you tend to be a particularly restless sleeper.

Is The Amerisleep AS3 Mattress  Good For Stomach Sleepers?

Due to its quilted foam top, the Amerisleep AS3 is a perfect mattress for stomach sleepers. Because it offers less sinkage than traditional memory foam models, it can keep your hips and shoulders from sinking too far into the bed. This helps prevent the excessive rotation of your spine that can cause back pain in this position while also reducing pressure points that can lead to hip pain or numbness in the arms and hands.
