Amerisleep AS3 vs DreamCloud: Which Foam Mattress Wins?

Two all-foam mattresses, two very different shopping experiences. Skip both if you want coils; the Saatva Classic is the innerspring alternative. The Amerisleep AS3 is a medium-feel, 12-inch foam mattress built around plant-based Bio-Pur memory foam and HIVE targeted support, sold with a 100-night trial and a 20-year warranty. The DreamCloud Classic Memory Foam is a 5-layer foam bed with a CloudQuilt cover, cooling fiber technology and 1 inch of pressure-relieving memory foam, sold with a 365-night trial and a Forever Warranty. Both target sleepers who want contouring without coils, but they split on trial length, warranty term and how much cooling detail each brand puts forward. This comparison walks through feel, materials, temperature, trial terms and value so you can pick the one that matches how you actually sleep.

Which mattress should you choose between the Amerisleep AS3 and DreamCloud?

The short answer: pick the Amerisleep AS3 if you want a medium-feel foam mattress with a detailed cooling story and a 20-year warranty, and pick the DreamCloud Classic Memory Foam if you want a longer 365-night trial, a Forever Warranty and a simpler 5-layer foam build at a published queen price of $799. The AS3 leans on named foam technology and chiropractic endorsement; DreamCloud leans on trial length and warranty duration. Neither is sold by Saatva, so if you want coils and a choice of firmness instead of foam, the Saatva Classic is the alternative worth a look further down.

How do the Amerisleep AS3 and DreamCloud compare on paper?

Here is the side-by-side view. Every value below comes from each brand’s own product page. Where a figure is not stated there, the cell says so rather than guessing.

Two things jump out. First, the trial gap is large: 100 nights versus 365 nights. Second, the warranty terms are structurally different, a fixed 20-year term versus an open-ended Forever Warranty. Both mattresses ship free and both include free returns, so delivery is a wash.

How do the two mattresses feel and support you?

The AS3 is explicitly rated Medium and Amerisleep describes it as balanced comfort and support for all sleeping styles, with HIVE technology delivering targeted support and airflow. That positioning suits combination sleepers and couples who cannot agree on firmness, because a medium feel splits the difference between sink and push-back. The brand also frames the AS3 as its most popular mattress, chosen for pressure relief and responsive support.

DreamCloud describes the Classic Memory Foam as built for breathability, contouring and restorative rest, with 1 inch of pressure-relieving memory foam under a CloudQuilt cover. The page does not assign a firmness number, so if you need a specific feel grade before buying, that detail is not published here. What the page does say is that the memory foam layer is there for pressure relief and the overall design favors contouring sleepers.

If you sleep on your side and want a named medium feel with a stated support technology, the AS3 gives you more to go on. If you want a contouring foam bed and care more about trial length than a firmness label, DreamCloud holds its own.

Which mattress sleeps cooler?

The AS3 makes cooling a central claim. Amerisleep describes a Refresh cover made from a fiber with high energy transfer that draws heat from the skin for a cool-to-the-touch feel, and states that the sleeping surface stays on average 7 degrees cooler over an eight-hour night. The plant-based Bio-Pur memory foam uses an open-cell design so more air circulates than in traditional foam, which the brand links to less sweating and less tossing and turning. HIVE technology is also credited with maximizing airflow.

DreamCloud’s cooling story is shorter: the Classic features cooling fiber technology within its 5-layer build and a CloudQuilt cover, with breathability listed as a design goal. No temperature figure is given.

Hot sleepers who want a quantified cooling claim will find more detail on the Amerisleep side. Sleepers who just want a breathable foam cover without a number attached will find DreamCloud’s description adequate.

What materials is each mattress made from?

The AS3 all-foam build centers on Bio-Pur, Amerisleep’s plant-based memory foam. The brand describes it as open-cell, more breathable and more responsive than traditional memory foam, snapping back to its original shape in seconds so sleepers do not uncomfortably sink. Bio-Pur contains a fraction of the petrochemicals used in other memory foams, which Amerisleep says makes it less likely to off-gas and free of harmful substances. The mattress is fiberglass-free, non-toxic and made in the USA. HIVE technology provides targeted support across the surface.

DreamCloud’s Classic uses a 5-layer design with the signature CloudQuilt cover, cooling fiber technology and 1 inch of pressure-relieving memory foam. The page does not describe plant-based foams, fiberglass status or certifications, so those points are not part of this comparison.

For shoppers who prioritize what the foam is made from, the AS3 publishes considerably more material detail. For shoppers who simply want a layered foam bed with a quilted cover, DreamCloud’s description is straightforward.

What do trial, warranty and shipping look like for each?

Trial terms are the clearest dividing line. Amerisleep offers a 100-night sleep trial with easy and free returns. DreamCloud offers a 365-Night Home Trial with Free Shipping and Returns. If you are the kind of sleeper who needs a full year of seasons to decide, DreamCloud’s window is more than three times longer.

Warranty terms split the same way. Amerisleep backs the AS3 with a 20-year warranty. DreamCloud backs the Classic with a Forever Warranty. A fixed 20-year term is still substantial, but an indefinite warranty is a different promise.

Shipping is comparable: both brands advertise free shipping and free returns, and DreamCloud adds that in-stock orders ship in 1 to 2 days. Amerisleep notes free no-contact fast shipping. Neither page describes white-glove setup for these foam models.

Which mattress is the better value?

On published list prices, the DreamCloud Classic Memory Foam is listed at Queen: $799 and the Amerisleep AS3 all-foam at Queen: $1,149. Prices change with promotions, so treat these as the figures each page carried when this comparison was written.

Value is not only the sticker. The AS3’s higher price sits alongside a named foam technology, a stated cooling figure, fiberglass-free construction, a chiropractic endorsement and a Newsweek Readers’ Choice award. DreamCloud’s lower price sits alongside a longer trial and an indefinite warranty. Which bundle matters more depends on whether you weight material transparency and endorsements or trial flexibility and warranty length.

Shoppers who want the lowest entry price for a contouring foam bed will lean DreamCloud. Shoppers who want the fuller material and cooling disclosure will lean AS3.

Who should buy the Amerisleep AS3?

The AS3 is the pick for sleepers who want a medium-feel all-foam mattress with a documented approach to temperature regulation. If you sleep warm and want a brand that puts a number on its cooling claim, the Refresh cover and open-cell Bio-Pur give you something specific to evaluate. If you sleep in multiple positions or share the bed with a partner who prefers a different position, the medium feel and HIVE targeted support are designed to work across styles. If material composition matters to you, the fiberglass-free, plant-based, made-in-the-USA profile is clearly stated. The 100-night trial is shorter, so this is a mattress for buyers who are reasonably confident in a medium foam feel before ordering. It also suits shoppers who value third-party recognition, since the AS3 carries the Newsweek Readers’ Choice Best Mattress 2026 title and an American Chiropractic Association endorsement.

Who should buy the DreamCloud Classic Memory Foam?

DreamCloud is the pick for patient buyers and budget-conscious shoppers. The 365-night trial means you can live through a full year of temperature changes before committing, which matters if you have been burned by a shorter trial in the past. The Forever Warranty removes the question of what happens in year 15. The 5-layer build with a CloudQuilt cover and 1 inch of memory foam is a straightforward contouring design for sleepers who want pressure relief without a long materials lecture. It also suits buyers who want fast fulfillment, since in-stock orders ship in 1 to 2 days. If you do not need a firmness grade printed on the page and are comfortable buying on trial length and warranty alone, DreamCloud is the rational choice.

So which one wins the comparison?

The Amerisleep AS3 wins this face-to-face for shoppers who weigh construction detail, cooling specifics and endorsements. It publishes a feel grade, a temperature figure, a material story and two independent recognitions, and it backs all of it with a 20-year warranty. DreamCloud is not a bad mattress by any reading of these pages; it simply publishes less and asks you to buy on trial length, warranty duration and price. Choose DreamCloud if the 365-night trial and Forever Warranty are your deciding factors, or if $799 for a queen is the number that makes the decision for you. Choose the AS3 if you want to know exactly what you are sleeping on and how it is supposed to keep you cool.

If neither foam bed settles it for you, the Saatva Classic offers a different category entirely: an innerspring build with a Euro pillow top, three comfort levels, two heights and a dual-coil design, backed by a 365-night trial and a lifetime warranty with free white-glove delivery and old-mattress removal.

Frequently asked questions

Is the Amerisleep AS3 a hybrid or all-foam mattress?

The AS3 is sold in two versions: an all-foam model and an AS3 Hybrid that combines foam and coils. This comparison covers the all-foam version only, which is the 12-inch medium-feel model built with Bio-Pur memory foam and HIVE technology.

Does the DreamCloud Classic come in other firmness options?

The DreamCloud product page describes the Classic Memory Foam as one design and offers step-up options in the Premier and Premier+, which add height and additional contouring and cooling layers.

Can I return either mattress if it does not work out?

Both brands advertise free returns. Amerisleep pairs its free returns with a 100-night trial, and DreamCloud pairs its free returns with a 365-Night Home Trial. The return windows differ, so check the terms that apply at the time you order.

Do either of these mattresses contain fiberglass?

Amerisleep states that the AS3 is fiberglass-free, eco-friendly and non-toxic. The DreamCloud page does not address fiberglass, so that detail is not part of this comparison.

Which is better for hot sleepers?

The AS3 publishes the most cooling detail, including a Refresh cover and an average surface temperature claim of 7 degrees cooler over an eight-hour night. DreamCloud lists cooling fiber technology and breathability without a figure. If a quantified claim matters to you, the AS3 gives you one to evaluate.
