Amerisleep AS5 Mattress Highlights

Top Soft Mattress Badge

The Amerisleep AS5 is one of the five memory foam mattresses in the collection of memory foam mattresses by Amerisleep. This model is the softest of all five models, but it still has responsive properties so you don’t sink into the bed and get stuck.

Keep reading our in-depth Amerisleep AS5 mattress review to learn more about how this mattress performs and can bring you a better night’s sleep.

What sets it apart:

  • The AS5 is Amerisleep’s softest mattress model and is ideal for side sleepers and combination sleepers.
  • Its foam comfort layers create a soft but responsive feel that relieves pressure points and makes you feel like you’re floating.
  • In addition, the plant-based foam, which is known to regulate body temperature, wicks away any moisture.

AS5 Performance Highlights

✅ Pros

  • Pressure Relief: It means that when you’re sleeping on the AS5, not only are you ultra-comfortable from the soft surface, but you also are getting the pressure relieving support you need to avoid pain in the hips, shoulders, and knees. This bed can make you feel like you’re floating!
  • Alignment: This bed is a good match for side sleepers looking for a comfortable, contouring bed that balances with enough support to maintain proper spine alignment.
  • Celliant Cover: Top that all off with the high-performance Celliant® cover and you’re practically guaranteed a good night’s sleep. This thermoreactive cover is designed to turn your body heat into infrared energy, meaning you’ll sleep cool all night long.

❌ Cons

  • Off-Gassing: Being an all-foam mattress, the AS5 will have an off-gassing odor after unboxing. This happens with all bed-in-a-box mattresses made with memory foam; just let it air out for a few hours and the smell will dissipate.
  • Social Responsibility: If you like to buy your products with a side of social impact, Amerisleep may not be the brand for you.

AS5 Firmness Level

Out of the five memory foam Amerisleep mattresses, the AS5 is the most plush option, coming in at a 3/10 on the firmness scale. This medium-soft/soft firmness works best for side sleepers; see why in the next section.

Is It Good for Your Sleeping Position?

Let’s cover how the AS5 works for side, back, stomach, and combination sleepers:

  • Side sleepers will most likely enjoy this soft mattress the most because it cradles their hips and shoulders while allowing their spine to stay straight.
  • Thanks to the responsive foam layer, combination sleepers should have an easier time shifting from one position to the next.
  • Back sleepers and stomach sleepers need a mattress that is at least medium-firm for a good spinal alignment, so we do not recommend the AS5 for them.

Does It Sleep Hot?

The AS5 is designed to sleep cool. The open-cell foams allow air to escape, plus the breathable cover helps wick away body heat. Of course, the more thick bedding and pajamas you bring into bed could have an effect on your body temperature. And in addition, innerspring mattresses and those with latex foam will sleep cooler.

Can the AS5 Support Your Weight?

The AS5 has a weight limit of 700 pounds for a queen size mattress. This is about a 350 pound limit per side, which works for most body types. However, if you consider yourself to be a heavier sleeper, we encourage you to look at a bed with springs or thicker density foam to feel more supported.

Do You Need a Specific Foundation?

All you need to be supported in the AS5 mattress is a flat surface. This includes a slatted frame, a flat frame, a box spring with plywood—even an adjustable base or the floor.

The Inside Layers

The AS5 mattress is made in the USA with CertiPUR-US Certified foams. Check out how they use these materials to make a cozy mattress.

Inside the Amerisleep AS5
  1. Breathable Mattress Cover: The soft cover of the AS5 allows air to escape, keeping hot sleepers from overheating.
  2. Bio-Pur Foam: Top layer made with breathable cooling foam with an open-cell structure.
  3. Active Flex Layer: This layer is what makes this bed work for combo sleepers using its responsive comfort foam.
  4. HIVE Transition Layer: Using ergonomic transition foam, this layer provides pressure and pain relief.
  5. Bio-Core Foam Support Layer: Eco-friendly, high-density foam adds durability. The support foam base layer gives this bed the ability to have a 20-year warranty.

Once you receive your mattress, you have 100 days to decide if you want to return it for a full refund or exchange it for another model. Keep in mind that it can take up to 30 days to adjust to a new mattress so you may want to take some time before making any decision.

What Do Customers Say?

  • “My sister recommended this company after researching for an eco friendly (least toxic) mattress. Their customer service is top notch. I love my mattress, having purchased it in Apr. 2018. I went w/ the AS5 and it is very comfortable, not too soft or too firm. I didn’t want it too firm. I weigh 110 lbs. It was a little challenging getting it up to the second floor due to its weight (needed 2 people), so definitely wait until you get it to the designated room before opening it up! I got a queen size. Definitely get the mattress protector, regardless if you have pets on the bed to protect your investment. Enjoy!”  – Solta
  • “Finally a soft mattress!…The wife and I have been sleeping on the A5 for the past two weeks and wow! I’ve been waking up without pain. The mattress also sleeps cool. Recommend purchasing the sheets to go with the mattress. It’s worth the money.” – Criag
  • “I bought the as5 split king. The mattress is all i hoped for. soft at about a 5.5 rating but firm enough so as to keep my back from aching. I have improved sleep from this mattress. Spent a lot of time evaluating mattresses on line and visiting stores. I really liked the tempurpedic pro adapt soft and the breeze soft. This amerisleep is on equal footing with these mattresses. I am a side sleeper but also wind up on my back. Best sleep in a long time. I purchased a dynasty split king adjustable bed frame and this mattress works well with it.” – Patrick

Is the AS5 Mattress for You?

As we’re reaching the end of this Amerisleep mattress review, it’s time to ask the key question: is the AS5 the bed you want in your room? The answer is yes if you fall under any of these categories:

  • You sleep on your side.
  • You toss and turn.
  • You love a cozy mattress that lets you sink in.
  • You sleep hot, but want a foam bed.

We think you should look elsewhere if you fall under these categories:

  • You sleep on your back or stomach.
  • You’re shopping on a budget.
  • You want a bed with springs.

If you decide that the AS5 isn’t for you, allow us to offer you some alternatives:

  • If you sleep on your back or stomach, consider the Layla mattress.
  • If you are budget shopping, consider Nectar.
  • If you’re looking for a hybrid mattress, consider Helix Midnight.

Compare AS5

As you know, the Amerisleep AS5 is one of 5 Amerisleep memory foam beds. Let’s discuss how they compare.

  • Amerisleep AS1: AS1 is the firmest bed Amerisleep has to offer, perfect for most stomach and some back sleepers.
  • Amerisleep AS2: The AS2 is still a firm mattress, but less firm than the AS1, still great for back and stomach sleepers.
  • Amerisleep AS3: AS3 is the most popular Amerisleep mattress due to it’s universal medium firmness.
  • Amerisleep AS4: We get a little softer over at the AS4. This is the perfect Amerisleep bed for side sleepers, back sleepers, and those who want a little extra cushioning.
