If you’re not completely satisfied with your new Amerisleep AS3, you can return it within 100 days after purchase as part of the company’s 100-night sleep trial. The bottom layer of the AS3, the Bio-Core® layer, supports all the other layers, giving the mattress durability and longevity you can trust. The same detail-oriented design optimizes pressure-relief in your shoulders and hips to give you more cushion. The HIVE technology gives you targeted support and comfort from hundreds of hexagon-shaped cutouts that are meticulously arranged for optimal support where you need it most, like your head, back, and feet. The Affinity layer with HIVE® technology offers relief for chronic pain and naturally reinforces a neutral alignment of the spine. Bio-Pur® is also more responsive, springing back to its original form in 3 to 4 seconds compared to the average 20 to 30-second response rate among other memory foam brands. The top layer of Bio-Pur®, a plush foam, is more breathable than traditional memory foam, keeping you cool all night long. The Amerisleep AS3’s contains unique technology for excellent pressure relief and cooling ability. With its medium firmness, durable support, and plush comfort, this mattress is an excellent choice for side and combo sleepers. One of the reasons this mattress is so popular is because it’s so versatile and accommodating for a variety of sleepers. Meet the Amerisleep AS3, the best-selling mattress from Amerisleep.
