Amerisleep is a familiar name in the memory foam mattress world. The brand is popular for its exclusive line of soft to firm bed-in-a-box mattresses. This guide covers what sets Amerisleep apart and walks through its models, including firmness, who each one suits, and which older models have been retired.

The Amerisleep Lineup

Amerisleep’s mattress page currently lists the AS2, AS3, AS5 and a newer AS6, and the AS1 still has its own product page.[1][2] The AS4 page now redirects to the AS3, so we treat the AS4 as no longer sold.[3] The older names (Americana, Revere, Liberty, Colonial and Independence) are former names for the AS1 to AS5; Amerisleep no longer uses them.
  • AS1 (formerly the Americana): the firmest model at 10 inches, with 2 inches of Bio-Pur® memory foam over 8 inches of Bio-Core® base foam. It has no hybrid version.[2]
  • AS2 (formerly the Revere): a 12-inch medium-firm mattress. The Bio-Pur® comfort layer sits on top, with the HIVE® transition layer underneath it and the Bio-Core® base at the bottom.[4] Amerisleep also mentions an AS2 Hybrid.[2]
  • AS3 (formerly the Liberty): a 12-inch medium mattress with the same Bio-Pur®, HIVE® and Bio-Core® layering. It comes in all-foam and hybrid versions.[3]
  • AS4 (formerly the Colonial): a medium-soft 12-inch model that no longer appears in the lineup.[3]
  • AS5 (formerly the Independence): the softest model at 14 inches. It adds an Active Flex layer to the HIVE® layer and comes in all-foam or hybrid (foam plus coils) versions.[5]
Amerisleep no longer publishes layer thicknesses for the AS2 to AS5 or foam densities (PCF) for any model, so we’ve dropped the older figures.

Stand Out Features Of Amerisleep Brand & Mattresses

How did Amerisleep stand out in the crowded online mattress market? We think it’s because of these features.
  • A range of firmness levels, from firm to soft, in all-foam and hybrid builds.
  • You get a 100-night trial, but you need to sleep on it for at least the first 30 nights before you can return it for a refund.[2]
  • The warranty runs 20 years: the first 10 years cover replacement for defects, including sagging deeper than 1.5 inches, and the second 10 years are prorated.[2]
  • Amerisleep says it uses partly plant-based foams and its Refresh cooling cover, and describes them as more eco-friendly and cooler.
  • Residing in the US? You are eligible for free shipping. Amerisleep says the mattresses are made in the USA from U.S. and imported components, with covers sewn in Canada.[2]
  • Amerisleep particularly delivers mattresses vacuum sealed and rolled in a box.

Common Features Across All Amerisleep Mattresses

  • Refresh Cover – This replaced the Celliant cover that older Amerisleep mattresses used. Amerisleep says it feels cool to the touch and keeps the surface 7 degrees cooler on average than a plain polyester cover. Its claims about far infrared energy and circulation are the maker’s, not ours.[4]
  • Bio-Pur™ memory foam – Just like Simmons mattresses, Amerisleep mattresses use bio-based foams, and for good reasons. Amerisleep says replacing some petroleum with plant oils makes the foam more breathable. The foam is still polyurethane.
  • Responsive Memory Foam Feel – We all hate that feeling of getting stuck in the mattress, right? Amerisleep describes its foam as quicker to respond than traditional memory foam.
  • Firm to soft options – Amerisleep offers firmer and softer models, and hybrid versions of some.
  • Cool Sleeping – Amerisleep says its cover and foams help the mattress sleep cooler.
  • Green Manufacturing – Amerisleep markets its mattresses as made with more eco-friendly materials.
