Amerisleep Highlights

Amerisleep AS3 mattress
  1. The AS3 is Amerisleep’s most popular mattress model. Hitting the sweet spot of mattress firmness (not too firm, but not too soft), it’s a great option for people who tend to change positions throughout the night.
  2. Its foam comfort layers create a soft but responsive feel that relieves pressure points and makes you feel like you’re floating.
  3. The cover contains Celliant, which is known to reduce pain, regulate body temperature, and promote healthy blood circulation.
