Getting the right mix of comfort and support in a mattress can be a challenge, especially in one made from memory foam.

Because while these mattresses can be extremely comfortable they don't always offer the level of support you need to keep your back healthy and out of pain. 

However there are some that buck this trend and the Amerisleep AS2 mattress is one of those. 

As this mattress claims to have a firm and supportive feel to it despite being made from memory foam. 

So in theory your back should get the extra support it needs while you can still enjoy the comfort of pressure relieving qualities of sleeping on memory foam. 

But does​ the Amerisleep AS2 mattress deliver on this promise?

Or is it just another memory foam mattress that fails to provide adequate support for your back?

How Is The Amerisleep AS2 Mattress Made Up?

The Amerisleep AS2 mattress is a 12" thick medium-firm mattress made up of 3 layers of foam and covered with a polyester/celliant blend material.

And it's constructed as follows.

Top Comfort Layer

The top layer of this mattress is 2" thick and made with Bio-Pur memory foam.

And with an ILD (indentation load deflection) of 10 it's pretty soft.

So this is where you will get the initial comfort from as the foam molds to the contours of your body.

And this foam is made with an open cell structure that allows air to pass through it.

Which makes it 5 times more breathable than traditional memory foam and will keep you cooler during the night.

Transition Layer

Underneath this is a 3" layer of polyfoam that acts as a transition between the comfort of the memory foam top layer and the support of the high-density foam base layer.

This layer is much firmer (ILD of 40) and zoned so you get extra support and pressure relief in areas where you need it such as the shoulders and lower back.

And this firmness also helps to stop you sinking into the memory foam too much.

Like the top layer it's also designed to allow air to pass through it, so it also helps to keep the mattress cool to sleep on.

Bottom Base Layer

The 7" base layer of high-density foam is what gives the mattress it's support and stability.

And with it's thickness and an ILD of 35 it's a very firm foam.

Which allows the two layers above to work their magic.

It will also prevent the mattress from sagging over time, which can be a problem in other memory foam mattresses.

The Cover

These 3 layers of foam are covered with a soft and comfortable feeling polyester/celliant blend material.

And being made with celliant it's great for keeping you cool as well as comfortable.

As Amerisleep claim that it's made with 13 thermoreactive minerals that convert your body heat into infrared light.

Which sounds a bit space-age for a mattress cover but if it keeps you cooler at least it's still all good!

Why It's Good For Your Back

Memory foam is not usually your first port of call when it comes to looking for a mattress that will provide extra support for your back.

Because traditionally memory foam mattresses tend to offer more comfort than they do support.

However, the Amerisleep AS2 mattress is different.

Because the two layers of dense foam underneath the top memory foam layer​ gives this one a much firmer feel.

Which is great for your back as sleeping on a medium-firm mattress is widely regarded to be the best option for keeping your back healthy.​

So let's look at exactly what the AS2 will give your back.

Firstly the top layer of Bio-Pur memory foam will cushion your body as you sleep, which is great for relieving pressure.

And although this layer is soft, the transition layer of foam beneath it is firm and will stop you from sinking in too far.​

This transition layer also provides an element of springiness into the mattress which allows it to push back against your body weight and provide support.

Which will help to keep your spine in alignment and your sleeping posture healthy, which will also relieve pressure and tension.

However, while this 'push back' effect is good, it's not as good as you'd get on a latex mattress.

The transition layer is also zoned meaning that it offers you more support where you need it such as under your shoulders, hips, and lower back.

This is a great feature and a real selling point as it helps to spread the pressure evenly while you sleep and stops any pressure points from developing.

And the base layer of high-density foam helps to give you support and stability throughout the night.

This will also stop the mattress from sagging over time, which can be a major cause of back pain (and a real annoyance!).

Finally, the celliant used in the blend of materials for the cover is said to turn your body heat into infrared light.

And this has been shown to increase blood flow and circulation.

Which is great for your back as it helps your body to deliver the oxygen and nutrients to your damaged muscles that they need to heal and repair.

So while the Amerisleep AS2 is not as supportive for your back as a latex mattress, it still does a very commendable job.

And when you add to that the extra comfort the memory foam gives you then it could be a nice trade off.

Is It Comfortable Too

Now as you'd expect from a memory foam mattress, the Amerisleep AS2 mattress is really comfortable to sleep on.

However, if you are expecting a soft and squishy feeling memory foam mattress you may be disappointed.

Because the AS2 is pretty firm by comparison.

And that may make it a bit uncomfortable for some, especially side sleepers.​

But for those that don't mind a firmer and more supportive feel, the AS2 has plenty going for it in the comfort department.

Firstly the memory foam top layer is soft and molds to the contours of your body as you lie down on it.

Which helps to relieve pressure and tension and gives you an elevated and weightless feeling.

This can really help you to get into a deeper and more restorative sleep during the night as it eliminates the need for constant tossing and turning.

However, if you do need to change positions the AS2 has you covered.

As the Bio-Pur memory foam recovers it's shape far more quickly than traditional memory foam, making it easier to move around in and not get stuck.

And this mattress also does a great job of staying cooler​ than traditional memory foam mattresses.

As the open cell structure of the foam makes it 5 times more breathable than traditional memory foam.

And the transition layer also has a contoured design which allows air to flow through it and keeps the mattress cool.

Also the polyester/celliant blend cover is designed to wick away heat and moisture from your body as you sleep, while also being soft to the touch and comfortable to lie down on.

Which all adds up to a cool and comfortable night's sleep.

So if you don't mind a firmer feel you should experience plenty of comfort sleeping on the Amerisleep AS2 mattress.

Other Mattresses In The Amerisleep Range

I decided to review the Amerisleep AS2 mattress here as I believe it's the best option for people with back pain.

This is because it has a medium-firmness that gives it good support while not being so firm that it becomes uncomfortable.

However, Amerisleep make five different versions of this mattress so everyone can find their perfect fit.

Each one has a similar make up but offers different levels of comfort, firmness, and support.

So if you want a softer or firmer mattress than the AS2 you have options.

The full range is as follows:

  • AS1 mattress - The firmest mattress and good for back and stomach sleepers.
  • AS2 mattress - Medium-firm mattress featured in this review.
  • AS3 mattress - Has a medium feel which is a bit softer but still offers decent support.
  • AS4 mattress - Medium-soft mattress which is good for side sleepers.
  • AS5 mattress - Their softest mattress providing a luxurious feel but not much in the way of support.

Some Other Nice Features

It's An Eco-Friendly Mattress

Amerisleep prides itself on being an eco-friendly mattress company, both in how their mattresses are made and manufactured and how they are delivered.

So you don't just get a mattress that's good for your back, you also get one that's good for the environment too because:

  • They use a plant-based formula to replace petroleum when making their memory foams.
  • This also improves the indoor air quality of your bedroom.
  • They follow a zero emissions manufacturing process that meets the Clean Air Act's standards as it contributes no air pollution.
  • Your mattress is shipped to your door in a box that is recycled from consumer materials.
  • They'll also either donate returned mattresses to charity or recycle them.

Which are all nice bonuses to have on top of getting a great mattress.

You Get A 100-Night Free Trial

Choosing the right mattress is no easy task.

Buying a new mattress can be a big risk.

Because they cost a lot of money and if you pick the wrong one then you are stuck with it.

So the 100-night free trial with the Amerisleep AS2 mattress is brilliant.

As you'll get 3 months to sleep on it in the comfort of your own home before having to commit to buying it.

This is more than enough time to really know if it's the right one for you.

And if it isn't they will collect it from you and refund you completely.

Meaning you have nothing to worry about and nothing to lose when purchasing one.

So you'll get to sleep easy in more ways than one!

And A Conditional 20-Year Warranty

The Amerisleep range of mattresses are all well made and contain high quality materials.

This makes them extremely durable and the AS2 is no exception.

However, in addition to this you are also covered with a pretty good warranty when you buy one.

As for the first 10 years they will repair or replace your mattress if there are any structural defects.

So you know you're guaranteed to get plenty of life out of your AS2.

However, for years 11-20 after purchase you will have to pay 50% of the original cost plus shipping and transportation if you want to get your mattress replaced.

No Hassle Mattress Shopping

Traditionally mattress shopping has been a pain in the backside.

As you trawl around department store after department store getting ever more confused at the seemingly endless selection of mattresses.

And dealing with pushy salespeople following you around with a hungry look in their eyes.

When you do finally make you selection you then have to get it home.

Which can be a problem if you don't have a big van and instead have to tie it on to the roof of your car instead.

Then you have to shoehorn it up the stairs and into your bedroom, knocking all the pictures off the wall and putting your back out in the process.


So why not order an Amerisleep AS2 mattress online, get it delivered directly to your door for free in a box, carry it up to your bedroom with ease, and finally unwrap it in place.​

So much easier!

Money Off Promotions

The Amerisleep AS2 mattress is priced slightly higher than some other online mattresses.

This is because it's made with higher quality materials as it's aiming to compete with more high end mattresses.

However, a great thing about them is that are constantly running money off promotions, so you very rarely have to pay the full price.

And these discounts usually run at around $200 off.

So they bring the cost down closer towards the lower end mattress prices, meaning you get a higher quality mattress at a bargain price.

>> The Back On Site Verdict <<

So would I recommend the Amerisleep AS2 mattress for people with back pain?

I'd say overall it's a good choice if you are the type that enjoys a memory foam feel to your mattress.

As this mattress does a great job of giving you support underneath the memory foam which can keep your back healthy as well as comfortable.

Which for a memory foam mattress is quite rare, so the AS2 is one of the best around for that.

Although it should be noted that it still won't match the back support you'd get from a latex mattress.

And because it offers this support it will have a firmer feel to it than traditional memory foam.

But if you don't mind that it can give you a really comfortable, relaxing, and cool night's sleep.

And help your back to get the rest it needs while keeping your body supported and in alignment.

So if you want to keep the comfort of memory foam while also getting more support for your back in your new mattress don't hesitate to give the Amerisleep AS2 a try.
