Below we have our through Amerisleep AS3 mattress review. We will go through how it should perform in several categories. Including comfort, motion transfer, sleeping cool and edge support. As well as the value, materials and construction and trial period and warranty. Giving you a well rounded look at what this mattress has to offer.

Delivery & Off Gassing:

amerisleep as3 mattressEach Amerisleep mattress, including the AS3, is shipped for free. Each bed is compressed, rolled up and placed into a fairly compact box. It is than shipped via FedEx with a delivery date out about a week from placing your order. Once it arrives the fun can start. All you need to do is get the mattress to where it will be placed. Simply remove it from the box and position on your base and cut the plastic away.

It will probably only take a few minutes for the initial expansion. However, it will take about 24 to 48 hours before it is fully firmed up and true to feel. So even though it may look good to go after 5 to 10 minutes the feel will alter over that first day or so, so keep that in mind.

During with unboxing process you may notice a few “new” mattress smells. This mattress should have fairly minimal off gassing and any scent that dissipates shouldn’t be harmful. Especially since Amerisleep does use more environmentally friendly foams and materials. However, if you are more sensitive to smells or want to be cautious opening a window or stepping out of the room during this time is helpful.

Amerisleep AS3 Mattress – Comfort:

amerisleep as3 mattressThe Amerisleep AS3 is their most popular mattress for obvious reasons. The comfort of this bed is going to appeal to the broadest spectrum of sleepers. It is an ideal medium feel that on a firmness spectrum falls right in the middle. Creating a good compromise for couples as well as anyone who sleeps in multiple positions.

The comfort of this memory foam mattress may appeal more than others due to it’s fast response time. The top layer of memory foam is not only great for relieving pressure points it also moves with your body much quicker. Instead of taking up to a minute to catch up with you it only takes a few seconds. Never making you feel stuck like most memory foam beds do. This combine with the unique Affinity Transition layer creates a harmonious blend of weightlessness and even support. While the base layers gives a long term durable feel and solid foundation.

Amerisleep AS3 Mattress – Motion Transfer:

amerisleep as3 mattressThe motion transfer with the AS3 by Amerisleep should be minimal. This mattress is made of all foam that absorbs most movements quickly. And though the foams have a bit of response they will by no means produce any large amount of excess vibrations. Making this mattress a good choice for anyone looking for a bed with good motion isolation. Including light sleepers or partners who have different sleep schedules.

Amerisleep AS3 Mattress – Sleeping Cool:

Amerisleep has focused not only on ideal comfort and support but also a mattress that sleeps cool. Using foams and materials in each design to work with your body to sleep comfortably all night long. The Amerisleep AS3 has several layers that allow it to stay more temperature neutral from the time you go to sleep until you wake up.

amerisleep as3 mattressThe top layer of memory foam is not only more responsive allowing for easy moving and a less stuck feel. It also has an open cell structure that allows more space and air to flow. Creating better heat dissipation and less heat retention. The middle transition layer also has a clever design that is not only meant for great weight distribution but also has channels that create breathablilty and yet another place for heat to escape.

Lastly, the firm core base layer creates a “no sag” foundation that keeps you from being too far into the bed. And the less you are “in” the mattress the more air that is allowed to flow around your body. Creating less heat build up. All of this is even wrapped in a Celliant infused cover that is breathable as well as takes any body heat and uses it to help repair and rejuvenate your body.

Amerisleep AS3 Mattress – Edge Support:

amerisleep as3 mattressThe Amerislep AS3 mattress is a thick 12″ of solid foams. This bed should feel very solid and consistent from every angle. Making it not only fully usable but creating a bed that allows you to sleep right up to the edge without feeling like you will roll out. The consistency in the materials and durable build not only give you full access to the mattresses sleeping space. It also helps ensure the longevity of the mattress.

Though we never recommend to use your bed as a sitting surface, especially for long periods of time, it is still nice to use it infrequently for day to day tasks. Sitting on the edge of the Amerisleep AS3 should provide a fairly firm feel, however, placing your weight in one spot along the edge will create a semi significant indent. And if continued overtime will break down the sides of the bed. Making the edge support good, but better for sleeping than sitting.

Amerisleep AS3 Mattress – Value: 

The Amerisleep AS3 mattress is not only the middle of the road for comfort but pricing too. This mattress starts at $1099 and ventures up to $2098 for split King.
