Amerisleep specializes in memory foam beds built to accommodate a wide variety of sleep styles. All Amerisleep models, from the AS1 to the AS5 mattress models, include at least two foam layers. A Bio-Pur top layer and a Bio-Core base layer, which provides high-density support for all sleep positions, are the same in each all-foam model.

All memory-foam models except the AS1 contain an additional layer of foam to provide cushioning and proper spinal alignment. The hybrid versions include both foam layers and pocketed coils designed to maintain alignment and alleviate pain-causing pressure points, which help to reduce back pain. We know the AS1–AS5 naming of these mattresses can be confusing, so our reviews deliver a comprehensive overview of each mattress: AS1, AS2, AS3, AS4 and AS5.

Amerisleep has a bed for every firmness level and type of sleeper, from back sleepers to side sleepers to stomach sleepers. Regardless of style or plushness, all Amerisleep mattresses are eco-friendly, made with quality materials, and backed by a 20-year limited warranty. During our review process, they’ve also received great scores in motion transfer and edge support. Let’s take a look at what the warranty covers, what it doesn’t, and how it measures up to other mattress warranties across the industry.

Amerisleep Mattress Warranty Overview

Amerisleep offers the same warranty for both its memory foam mattresses and hybrid mattresses, which is very common in the industry. The length of the warranty and the types of damage covered—both of which we’ll explore more below—also match industry standards. In our opinion, Amerisleep offers a solid mattress warranty on all their mattresses; there’s nothing in the fine print to cause any concern.

How Long Does Amerisleep’s Warranty Period Last?

All Amerisleep models come with a 20-year warranty. This warranty length is better than companies like Casper or Purple that offer a 10-year warranty. Still, the Amerisleep warranty isn’t quite as good as companies like Puffy or Nectar, which offer a lifetime warranty. It’s also worth noting that the Amerisleep warranty coverage changes after the first 10 years of ownership.

If you file a valid warranty claim during the first 10 years, Amerisleep will replace or repair the mattress for free. During the second 10 years, however, Amerisleep will replace the mattress with a new bed for 50 percent of the original purchase price. This is called a prorated warranty. It’s typically not considered the best mattress warranty policy, but this particular arrangement seems fair.


What is Covered by the Amerisleep Warranty?

Body Indentations Greater Than 0.75”

The only issue specifically covered by the Amerisleep mattress warranty is body indentations. The top layer of each Amerisleep mattress is a special proprietary memory foam called Bio-Pur foam. It’s made from eco-friendly and renewable plant-based oils, and it has an open-cell structure to prevent body-heat buildup.

If you notice that this top layer has a permanent indentation, then you should be able to file a warranty claim and get a new mattress. Over time, memory foam softens and stops bouncing back as quickly, but it shouldn’t show permanent sagging or body indentations during the warranty period. If you measure these spots in your mattress and they are deeper than 0.75”, then you can file a claim with Amerisleep to get a new mattress.

Faulty Workmanship

The Amerisleep warranty also mentions “faulty workmanship” and “structural defects,” though it doesn’t give an exact explanation of what either of these issues would entail. This is not ideal, because it’s much easier to get your warranty claim processed if it meets the exact specifications of the warranty, and it’s impossible to do that if the warranty doesn’t lay out specific terms.

Generally, “faulty workmanship” refers to issues with the mattress dimensions or defects in the mattress cover not caused by the purchaser. If you’re having an issue with your Amerisleep mattress or the Celliant cover but aren’t sure whether it’s covered by the warranty, direct your questions to

What is Not Covered by the Amerisleep Warranty?

The Firmness Is Not What I Expected

Amerisleep mattresses come in five models with different firmness levels. The AS1 is the firmest, the AS5 is the softest, and the Amerisleep AS3 mattress falls right in the middle with a medium firmness. The AS2 mattress and AS4 mattress are on the firmer and softer side, respectively. Unexpected firmness is not covered by the warranty. For instance, if your mattress arrives and it’s more medium-soft than the medium-firm construction you were expecting, or if you find that it doesn’t work for your sleeping position, these firmness issues are not covered by the warranty.

Amerisleep doesn’t cover comfort preferences in general. Thankfully, the company does offer a 100-night sleep trial period when you can test the mattress at home. So, if it’s been less than 100 days since you purchased the mattress and you don’t like it for any reason during that trial period, you can return the bed for a full refund. This return policy allows people to buy bed-in-a-box mattresses without taking the risk of not liking the feel of the mattress and getting stuck with it. However, if it has been more than 100 days, you won’t be able to get a refund for the bed: Again, comfort issues are not covered by the warranty.

I Accidentally Cut Through the Mattress During Unboxing

Any damage done to the mattress by the customer, rather than by the manufacturer, is not covered under the Amerisleep warranty. Unfortunately, even if you accidentally cut through the top comfort layer of foam on the first day of owning the mattress, this issue is not covered by the warranty. We recommend being very careful while unboxing the Amerisleep bed—or any other bed-in-a-box mattresses for that matter.

The Strong Off-Gassing Smell Is Giving Me Headaches

Upon unboxing, many compressed foam bed-in-a-box mattresses emit a chemical smell known as off-gassing. This odor comes from the release of chemicals called Volatile Organic Compounds (VOCs). If you’re used to innerspring mattresses, the smell might surprise you, but it is completely normal.

The foam in Amerisleep mattresses is CertiPUR-US certified, meaning it poses little to no health risk. However, this off-gassing smell can cause headaches or nausea for some people. This issue is not covered by the warranty. If it’s causing a significant problem, the best way to cope is to leave the windows in your house open as much as possible to get rid of the scent. Plan to let the bed air out for three to seven days in a well-ventilated room or garage. If it’s still an issue, then under the 100-day sleep trial period, you can return it.

Things That Would Void the Amerisleep Warranty

  • Use of an improper frame
  • Signs of physical abuse or misuse, such as burns, stains, cuts or tears
  • Moisture saturation
  • Unsanitary conditions
  • Transfer of ownership from the original purchaser

Filing A Warranty Claim with Amerisleep

To file a warranty claim with Amerisleep, you’ll need to prove that you have not voided the terms of Amerisleep’s warranty policy. You have to provide proof that you are the original owner of the mattress and that you have been using a proper bed frame. You also have to provide documentation that the issue you are claiming is a manufacturer’s defect. You can start the claims process over the phone or via email, but you will likely have to email documentation of the damage to Amerisleep at some point during the claims process.

If you end up filing a warranty claim with Amerisleep during the last 10 years of the warranty coverage period, you’ll be responsible for shipping costs associated with a replacement.

How to Start the Claims Process

  • Option 1: Call 1-800-500-4233. This is Amerisleep’s customer service line. A representative will walk you through the next steps to have your claim filed, processed and fulfilled.
  • Option 2: Email If you prefer to reach out online, you can email Amerisleep’s customer service department and a representative will help you through the rest of the claims process.

What you’ll need:

  • Original receipt of purchase
  • Photos or video of the issue
  • Photos of your mattress foundation to prove it isn’t “improper” as defined by the warranty

How Does the Amerisleep Warranty Measure Up? 

The Amerisleep warranty has a few potential drawbacks. It only offers full coverage for the first 10 years of the warranty, and it does not specify what types of issues are covered under “faulty workmanship.” This could make it difficult for some reasonable warranty claims to be accepted. However, a 20-year warranty is a great sign of trustworthiness and confidence from a mattress brand, especially since most people end up replacing their mattress in less than 10 years. The Amerisleep warranty is fairly average for industry standard, falling somewhere between a lifetime warranty and a 10-year warranty.

Caring for Your Amerisleep Mattress

A mattress warranty is a great way to protect your investment, so it’s important to avoid nullifying the warranty through misuse. We’ve compiled a few tips for caring for your Amerisleep mattress and ensuring that you don’t void the warranty.

Use the right bed frame. Amerisleep says not to use a box spring with any of their mattresses unless you lay a 0.75” thick piece of moisture-resistant plywood on top of the box spring. Instead, they recommend using a flat, solid bed platform or a slatted platform where the slats are no more than 3 inches apart. Amerisleep also says it’s safe to use their mattresses with an adjustable base, though we recommend using the Amerisleep adjustable bed frame to offer extra assurance that the frame won’t void the warranty.

Use a mattress protector. Stains, unsanitary conditions and moisture saturation can all void your Amerisleep warranty, so protect your mattress with a high-quality mattress protector.

Try fixing comfort issues with a mattress topper. Comfort preferences aren’t covered by the Amerisleep warranty, but that doesn’t mean you have to be stuck with an uncomfortable mattress. If you have a firm mattress and it is causing pain in your pressure points, like the hips, lower back and shoulders, a mattress topper might be able to help. Amerisleep offers several toppers that can provide an extra support layer, improve motion isolation or make your mattress a bit softer and more comfortable. The Amerisleep line of toppers comes in every size, including Twin XL and California King.
