"My husband was quite skeptical about buying a mattress unseen but I was impressed with the details and reviews so we decided to try it. The very first morning after our first night's sleep he said he liked it! My back took about a week to adjust but after that I liked it too. I like very much that it does not have an off-gassing of chemicals like most mattresses do. Plus it does not sleep hot like the other memory foams do. I'm very glad we bought it."

"I have purchased (2) AS3 mattresses. One is a Queen the other is a Twin size. We love these mattresses. They are comfortable and no more back aches in the morning. With so many choices for bed-in-a-box mattresses I picked Amerisleep because I liked the fact that they use environmentally friendly materials have a mattress cover that helps your body. I liked the first one so much that I purchased a second one. I recommend that you try it for yourself. And if you don't like it you can return it, but I doubt that you will because you will love it."

Laura Poole

"Best sleep of my life. These mattresses are a little more than the other bed in a box mattresses but it was so worth the extra money. The website helps you pick the mattress that is best for you based on how you sleep. It was spot on. I usually have trouble as a side sleeper because my hips and knees hurt from the pressure, but not with this bed. It is just firm enough but also soft enough for the mattress to hug your body a little. I love my mattress and recommend Amerisleep to everyone I know. Customer service over the phone was awesome too, the mattress came earlier than expected, right to my front door."

“Amerisleep has changed the way I sleep. I wake up refreshed every morning and can’t wait to get back into bed to sleep the next night away. Paired with my weighted blanket I sleep with unmatched comfort. My dog loves it too!! Thanks Amerisleep!!"

Mattress Sizes Available At Portland

Mattress size is an important consideration when choosing a new bed. If you buy something too small, you won’t have enough room to get comfortable. But if you buy something too big, it may make your bedroom feel cramped.

To make the shopping process easier, we break down each mattress size and who they’re recommended for below.

Twin Size Mattresses

Dimensions: 38 inches by 74 inches If you’re looking for a mattress for a smaller bedroom or a growing child, a twin is a good option. This provides enough room for one sleeper to get comfortable and doesn’t take up too much space. They’re even compatible with bunk beds to fit more sleepers in one bedroom.

Twin XL Size Mattresses

Dimensions 38 inches by 80 inches Twin XL mattresses are a better option for taller sleepers who need a little more legroom. Like the twin, these provide enough room for just one sleeper, but the extra five inches of length can accommodate sleepers over 6 feet tall.

Full Size Mattresses

Dimensions: 54 inches by 75 inches Full mattresses are ideal for solo sleepers who like a little more space to sprawl out and get comfy. These offer 16 extra inches of width in comparison to twin sizes, allowing more room to change sleeping positions or co-sleep with a pet or child. We suggest couples opt for queens over fulls though, as fulls cannot comfortably fit two adults.

Queen Size Mattresses

Dimensions: 60 inches by 80 inches Queens are good options for couples or solo sleepers. If you’re a solo sleeper with a larger bedroom and you like a bigger mattress, we say go for it. Queen mattresses are also a popular choice for couples; however, some couples may prefer to choose a king, instead.

King Size Mattresses

Dimensions: 76 inches by 80 inches King mattresses have equivalent dimensions of two twin mattresses placed next to each other, which is what makes them a great choice for couples. When sleeping on a king, each sleeper has 38 inches of personal space, so they can toss and turn all they want without disturbing their partner.

California King Size Mattresses

Dimensions: 72 inches by 84 inches We recommend California king size mattresses for sleepers over 6 feet tall since they offer an additional four inches of legroom. We should mention, though, that Cal kings are also four inches narrower than standard kings. So what you gain in legroom, you lose in wiggle room. While these mattresses are often viewed as bigger and better than regular king beds, they’re really just a better option for taller people.

Split King Size Mattresses

Dimensions: 38 inches by 80 inches Split king mattresses are a solution for couples who have different sleep needs. Say you really like soft beds, but your partner wants a firm bed, a split king is a perfect compromise. Split kings are two separate twin XL mattresses placed next to one another in a bed frame, so you get the dimensions of a king, but you get to choose your preferred levels of comfort and support for your side of the bed. Split king mattresses are also excellent options for those with adjustable bed frames. Pairing a split mattress with an adjustable frame allows you to adjust each side of the bed independently.

Frequently Asked Questions

Where are Amerisleep mattresses made?

We make each of our mattresses right here in the United States, and to make your life easier, we ship them direct to your doorstep (for free!).

How long do Amerisleep mattresses last?

Each of our mattresses is built to last at least 10 years, and we back each of our beds with a 20-year warranty to help you get better sleep for the next two decades.

Does Amerisleep need a box spring?

We recommend against using box springs with our mattresses because these mattress accessories can cause damage to foam beds. Instead, pair your new Amerisleep mattress with a solid or slatted mattress foundation. If you have a slatted mattress foundation, make sure the slats are no more than 2.75 inches apart.

Do Amerisleep mattresses sleep hot?

Our mattresses are designed with temperature regulation in mind. To combat heat retention and night sweats, we use advanced open-cell memory foam in our mattresses; this makes our beds five times more breathable than the typical memory foam mattress.

Is there a warranty on Amerisleep mattresses?

We offer a 20-year warranty with each of our mattresses to protect your bed from sagging and manufacturing defects. Our warranty covers sags greater than 1.5 inches, but does not cover normal wear and tear of the mattress.

How much does an Amerisleep mattress cost?

We carry five memory foam mattresses and three hybrids, their prices range from $899 to $2699.
