Testing Highlights

We’ll take you behind the scenes into some of the key moments from our testing process. If you really want to know what the AS1 mattress is like, this is a great place to find out the inside scoop.

Setting Up the Mattress

The AS1 mattress took us just under a  minute and a half to set up. It was light and easy to maneuver, but it didn’t take its full shape immediately after unboxing. Check out the video below to watch!

Testing Motion Transfer

If you have a sleeping partner (even if it’s a pet), then pull your sleeping masks up and pay attention for this test! We run two tests to evaluate how well a mattress can isolate motion across the bed. If you’re tired of being woken up by your sleeping partner or furry friend tossing and turning in their sleep, this should be a key factor in your decision.

After having one test subject lie on the mattress blindfolded while the other enters the bed, rolls around, and exits the bed, we also perform a wine test! This is one of the best visual ways to see how well a mattress absorbs motion.

Take a look at our video below. Although the wine was pretty shaky, the glass itself stayed still.  So we gave it a 7.5 out of 10 for this test.

Measuring Pressure Relief

No one wants to wake up with aches and pains. That’s why we measure how well a mattress can relieve pressure on your body. In an ideal state, your mattress will evenly distribute your body weight so you don’t have pressure build ups in the hips, shoulders, or knees.

How can you tell if this will happen? We use a pressure mapping film that measures areas of high and low pressure on the body. Warm colors = high pressure. Cool colors = low pressure and a happy night’s sleep. Take a look at our results for the AS1 mattress below.

Test subject two on the AS1.

We saw a lot of warm colors and deep red tones in RJ’s shoulders and hips. So we gave him a 6 for pressure relief. Asha’s shoulders, hips, and midsection stayed relatively pressure free so we gave her a 7.5. So for a total pressure relief score, the Amerisleep AS1 received a 6.75 out of 10.

Checking for Spine Alignment

Next, we take a closeup look at our tester’s spines to be sure the mattress can support neutral spine alignment. What we’re looking for here is a straight line from the base of the spine to the top of the next.

Take a look below to see what we saw.

Both RJ and Asha’s spines were pretty straight with a slight upwards curve towards the base of the neck, so the AS1 received an 8.75 out of 10 for this test.


Customer Reviews of the AS1

“I found Amerisleep online and decided to try it. It is one of the best beds I have ever owned! I have purchased several very expensive beds in my lifetime. I am so impressed with the price and how comfortable it is. My wife and i like a pretty firm bed. The A1 was perfect for us. I will be getting one for my guest bedroom as well.” – Tim

“Loved the AS1 for the first few nights, my husband not so much. But i called customer support and they are sending us a mattress topper so it would resemble the AS2. Great customer service, great products would recommend to everyone!!!!” – Jess

“This is a great firm mattress. Know that you want a very firm mattress before buying. If you do paperwork or live on your bed then this mattress provides a nice and very comfortable level / sturdy surface. There isn’t a lot of give in the mattress… so at night when you sleep the firmness is more apparent than when just sitting on the bed. I think the mattress is very true to how the website describes it.” – KP

AS1 Mattress FAQs

How does the 100-night trial work?

If you decide the AS1 mattress isn’t for you, you have 100 days after the delivery date to return it for a full refund or exchange. Remember it takes up to 30 days to fully adjust to a mattress, so give your body time to adjust before making a decision.

Can I use a box spring with the AS1 mattress?

You can, but Amerisleep recommends you place a 0.75-inch piece of moisture-resistant plywood on top to support the mattress as best as possible.  (Plus, their warranty requires this.)

When can I expect to receive my AS1 mattress?

You can expect your AS1 mattress to ship within 3-5 business days. Once it is shipped, it will take another 1-5 business days to arrive at your door.
