Amerisleep AS5 Mattress Review

The Amerisleep brand offers a wide range of mattresses, for all types of sleepers. The AS5 mattress is the softest they provide. It’s also the biggest, measuring 14 inches. It is made of memory foam. This will contort to your body. Because it’s so soft, this makes you feel like you are sleeping on a cloud. This helps to relieve your pressure points. It also allows you to move positions easily.

There are a few reasons why people enjoy sleeping on this mattress. First, it’s very comfortable, particularly if you are a side sleeper. It also uses open-cell foam. This is designed to wick away heat, maintaining a comfortable temperature. The mattress is well-constructed and will last for a long time. Plus, it comes with a generous trial period and a long warranty.

Based on this first impression, it seems like the AS5 is a well-rounded mattress. To find out how it performed, I decided to test it out for myself. Let’s look at how it performed.

You Will Like the Amerisleep AS5 Mattress if You:

  • You want a good value – The Luft stacks up to many of the big box store brands you will find in stores but will save you money and they are the manufacturer so you don’t pay the wholesale markup most brands have.
  • Like to sleep cool – The design of the Luft disperses heat efficiently. The quilting layers on top keep you from sleeping directly on the gel memory foam which can get warmer. In addition having coils vs a foam core helps to circulate air. ·
  • Want a soft mattress you can sink into
  • Are a side sleeper
  • Want an environmentally friendly product
  • Are looking for something that will keep you cool during the night

You Might Not Like the Amerisleep AS5 if You:

  • Sleep on your stomach or back
  • Want a firm mattress
  • Are only focused on the price

Amerisleep AS5 Mattress Construction

The AS5 is made with care. It is 14 inches thick and incorporates four layers. The top cover layer is made from Cellant. This helps to wick away heat from your body, for a cooler night’s sleep. Plus, it is soft to the touch.

The first layer down is Bio-Pur memory foam. This is almost five inches thick. It is made from open-cell technology, making it five times more breathable than other types of mattresses. This also helps to wick away heat.

The second layer is made from Active Flex-Foam. This is two inches thick. This has channels, which carry away heat. More importantly, it is designed to relieve pressure points.

The third layer consists of two inches of Affinity Transition Foam. As the name suggests, this provides a transition between the top layers and the base. It adds a lot of cushion to the mattress. In particular, you’ll feel it around your shoulders and neck.

The fourth layer is made from Bio-Core foam. This is the strong base layer, where you will be getting most of the spinal support. This is designed to be a very strong layer. As a result, it ensures that your mattress will be durable. It won’t bend or sag, even after decades of use.

Another element that sets this mattress apart is the way that it was manufactured. The foam is made from plant materials, rather than the more traditional petrol. This makes their products environmentally friendly. They don’t use any emissions to produce it. As a result, they can exceed the standards set out in the Clean Air Act. The box the mattress comes in can be recycled.

AS5 Mattress Cover

Performance Cover:

The Propel mattress cover is soft and smooth and offers phenomenal benefits. Having a technology driven cover is one of the highlights of the Propel mattress. The cover is made from an elite European performance fabric that uses Upcycle technology. This innovative material uses encapsulated minerals to capture body heat and turn it into restorative energy.

This fabric used for the cover also stimulates blood flow to your body which means that your body will really relax and you’ll have improved mental and physical well-being. You will literally wake up feeling like a new person

AS5 Foundation

The AS5 can be used on any solid surface. Whether you pop it on the floor, on a wood foundation, boxspring, platform with slats or an adjustable base it will perform great.

Firmness & Feel

My thoughts (Ross)

Obviously, one of the most important parts of buying a mattress is picking something that will provide a comfortable night’s sleep. The AS5 is the softest mattress that Amerisleep offers. This is good for those who prefer to sink into the bed. It’s also good for those who like to sleep on their side, with the foam molding to the shape of your body.

One of the benefits of a softer mattress is that it can be a good way of relieving pressure. There is a layer of foam to help with this. As a result, it can feel like you are sleeping on a cloud.

However, it won’t be to everyone’s taste. If you sleep on your stomach or back, you might prefer something that is a little firmer. It might also cause some problems for heavier sleepers, not providing enough spinal support.

On a more positive note, it offers excellent temperature support. As we’ll discuss later, it uses open-cell memory foam and a thermoreactive cover. This ensures that you won’t find yourself overheating during the night. Plus, this mattress has a strong core layer. This is designed to make sure that you have some spinal support. It’ll also prevent the mattress from sagging over time.

When you are using a traditional mattress, it takes 60 seconds to bounce back to its original shape. However, the AS5 takes just 4 seconds to return to normal. This eliminates the feeling that you are sinking into the bed.

Overall, how you feel about this mattress will depend on what you are looking for. If you want spinal support, this might not be the best choice for you. But if you want a soft mattress that you can sink into, this might be ideal.

10 Very Firm


No one wants to get a mattress that will retain heat throughout the night. You don’t want to feel as though you are sleeping in an oven. The good news is that the AS5 offers some technology to make sure that this isn’t happening. First, it has open-cell foam. This is designed to make the mattress more breathable. This is 5 times more cooling than other types of memory foam.

Another good technology is the Cellant cover. This is made from a thermoreactive material. This is a breathable material. It also helps to wick the heat away from your body. This stops the heat from getting trapped in the mattress.

However, the softness of the mattress might cause some problems. The density of the memory foam will naturally trap heat. When you are sinking into it, this means that you might start to sleep hotter. This can be especially bad for those who are heavier.

Motion Transfer

When you are sleeping with a partner, you don’t want them to wake up by moving in the middle of the night. In this area, having a memory foam mattress can be a significant advantage. The denser material is better at isolating motion. The thicker the mattress, the less likely it is that will feel any movement.

If you are a light sleeper, the 14-inch AS5 mattress will minimize the chances that your partner’s movements will disturb you. I am giving it a 9 out of 10 in this area.

Adjustable Base Performance:

The Propel will great on an adjustable base.

Edge Support

Edge support refers to the way that sides of the mattress have been made. The right amount of edge support will allow you to avoid the sensation of falling off the bed. Plus, it will allow you to comfortably sit on the edge of the bed.

Unfortunately, there isn’t much edge support on this mattress. This is more noticeable than in some of the firmer Amerisleep mattresses. If you are sitting on the edge of the bed, you’ll quickly find yourself sinking into the soft material. On the upside, every part of the bed can be used for sleeping.

Delivery & Setup – Off Gassing

I think that Amerisleep did a great job of making the process of ordering their products as easy as possible. The checkout was simple and hassle-free. They use FedEx, which delivers the mattress to your door. It ships fairly quickly and you should have it within a few weeks. You can track the status of your order through the Amerisleep website.

The Amerisleep Mattress comes in a cardboard box. This makes it easy to get it into the bedroom. Though it can be a bit heavy, so you’ll need to get someone to help you lift it.

Once you have it into your room, you’ll need to start unboxing. This is easy. You’ll just need to take it out of the box. Lay it on the bed, then cut the plastic. Within the first few minutes, you will notice the mattress expanding rapidly within the first few minutes. However, it will take a few days before the mattress is fully expanded. Because of this, your first few nights on the mattress might not be what you had expected. There is plenty of support on the Amerisleep website if you aren’t sure what to do.

Like all new mattresses, you can expect a slight smell when you take the AS2 out of the box. The good news is that it should fade fairly rapidly. To speed up this process, make sure that you are opening a window.

The good news is that the Amerisleep Mattresses don’t contain any harsh chemicals when producing the mattress. As a result, you won’t have to worry that the gas will make you sick. Because of this, I am giving it a 10 out of 10 in this area.

AS5 Warranty and More

Shipping – free shipping, it arrives compressed in a box generally in 2-7 business days
When you get a new mattress, it will take you some time to get used to it. Amerisleep offers a 100-night trial period. This gives you plenty of time to decide whether this is the right mattress for you. If you don’t like it, you can send it back for a full refund.

I also liked the long warranty period. It lasts for 20 years, which is longer than most other mattress manufacturers. This is split into two periods. The first ten years is the standard warranty period. The next ten years are prorated. You will be given be a discount on a new mattress, depending on how long the old one lasted.

The long trial period and warranty show that Amerisleep is proud to stand behind this product. In this area, I am giving the AS5 a 10 out of 10.

Overall Summary

I was quite happy with the quality of the materials. I think that this mattress was built to last for a long time. It won’t sag, even after decades of use. Plus, the mattress has been made from plant-based materials and doesn’t use any harmful materials.

Ordering and setting up the mattress was a good experience. It comes in a box, which makes it easy to put into position. Removing it from the box and getting it expanded was very straightforward.

There was a lot to like about the experience of sleeping on this mattress. It was relatively cool, the open-cell layer is five times more breathable than other mattresses on the market. Plus, the Cellant cover helps stop body heat from entering the mattress.

However, because it is so soft, it might not be right for everyone. It might be the best choice for those who sleep on their back or stomach. It doesn’t offer enough support for those who like to sleep in these positions.

I think it offers good value for money. A queen costs $2,099. Considering the quality construction of the mattress, which will last for years, I think this is reasonable. Plus, it includes free shipping to your home. All in all, I would recommend this mattress.
