I started these Amerisleep mattress reviews with one question: can a plant-based memory foam lineup hold up to real, everyday sleep in a lived-in home? We rotated these beds through normal routines—full nights, naps, reading, and late laptop sessions—to see what actually changed after the novelty wore off.
We tested four Amerisleep models: AS1, AS2, AS3, and AS5. Together they cover firm through ultra-plush. Each mattress stayed in place for multiple weeks, then we compared notes across different body types, sleep positions, and nightly habits.
Product Overview
We focused on four core Amerisleep all-foam models that sit at the center of the brand’s memory foam lineup. They share the same general “Amerisleep feel,” but the firmness and depth of contour change meaningfully from model to model.
| Mattress | Pros | Cons | Ideal For | Price (Queen, approx.) | Overall Score |
|---|---|---|---|---|---|
| Amerisleep AS1 | Very firm support; easy to stay aligned on your back or stomach | Too firm for many side sleepers | Firm lovers, back sleepers, some stomach sleepers, and heavier sleepers who dislike sink | Varies with promotions | 4.3 / 5 |
| Amerisleep AS2 | Strong lumbar support with zoned transition foam | Lightweight side sleepers may still feel shoulder pressure | Back sleepers, combination sleepers, and sleepers who want a more structured feel | Varies with promotions | 4.4 / 5 |
| Amerisleep AS3 | Balanced mix of contour and support for many body types | Very heavy stomach sleepers may want firmer support | Couples, average-weight sleepers, and most side sleepers | Varies with promotions | 4.5 / 5 |
| Amerisleep AS5 | Deep pressure relief with an extra Active Flex layer | Soft feel is not ideal for strict stomach sleepers | Side sleepers who want plush comfort, lighter bodies, and pain-sensitive joints | Varies with promotions | 4.4 / 5 |
Testing Team Takeaways
From my perspective, the Amerisleep lineup feels like one consistent foam character tuned across a firmness range. AS1 kept my lower back stacked and stable, while AS3 added enough contour at the hips and shoulders that I stopped noticing pressure during long side-sleep stretches.
Marcus focused on heat and hip support. He liked the “reset” pushback on AS2 and tolerated AS3 well, but he rode a bit deeper on AS5 than he wanted for all-night back sleeping.
Mia’s reactions were the clearest illustration of how firmness changes pressure relief. She struggled on AS1, felt balanced relief on AS3, and got the deepest cushion on AS5.
Jenna cared most about partner disturbance and edge use. She rated motion isolation very strong across the lineup, with AS5 being the quietest, and she preferred the firmer edges on AS1 and AS2 for sitting.
Amerisleep Mattress Comparison Chart
These four models share plant-based Bio-Pur foam and a Bio-Core support base. Where they separate is thickness, firmness, and how much cushion you get before the support layers push back.
| Mattress | Firmness (1–10, our scale) | Thickness | Construction Highlights | Cooling Performance | Support Level | Pressure Relief | Responsiveness | Motion Isolation | Durability Outlook |
|---|---|---|---|---|---|---|---|---|---|
| AS1 | 8–8.5 (firm) | 10" | 2" Bio-Pur comfort over 8" Bio-Core support | Moderately cool for a firm foam | Very strong under hips and lower back | Limited for most side sleepers | Faster than dense memory foam, yet taut | Very good due to thin top layer | Strong due to simple, firm build |
| AS2 | 7 (medium-firm) | 12" | 2" Bio-Pur, 3" HIVE zoned transition, 7" Bio-Core | Slightly cooler than average memory foam | Excellent for back alignment | Better than AS1, still on the firm side | Quick enough for easy position shifts | Very good for couples | Strong core plus zoning |
| AS3 | 6 (medium) | 12" | 3" Bio-Pur, 2" HIVE transition, 7" Bio-Core | Cool to neutral under most conditions | Solid for many body types | High for shoulders and hips | Balanced response for foam | Excellent for most couples | Strong, but softer comfort layers may show impressions sooner |
| AS5 | 4–4.5 (plush) | 14" | 3" Bio-Pur, 2" Active Flex, 2" HIVE, 7" Bio-Core | Neutral to slightly warm for heavier bodies | Adequate if you enjoy a soft feel | Very high, deeply cushioned | More responsive due to Active Flex | Excellent for restless partners | Good, though softer upper foams may show impressions sooner |
What We Tested and How We Tested It
We used the same evaluation grid across all four models, anchored to our core process in How We Test Mattresses. We focused on support, pressure relief, cooling, motion isolation, responsiveness, edge support, and firmness.
Each mattress stayed in one tester’s bedroom for at least three weeks. Early nights included deliberate position changes. After that, we slept normally and compared notes in the morning—aches, numb spots, and “this feels better/worse” comments that show up only after routine use.
We added structured checks where they were useful. Marcus measured sink under his hips and shoulders using stacked hardcover books and a tape measure. Jenna tested motion by staying still while her partner moved on the other side. Mia did longer side-sleep sessions to stress pressure points. I tracked lower-back tightness after long laptop sessions and compared it across models.
Scores from 3.0 to 5.0 come from the combination of those lived-in weeks and our standard checks, not from spec sheets alone.
Amerisleep Mattress: Our Testing Experience
Amerisleep AS1
Our Testing Experience
I started AS1 in my guest room, then moved it to Marcus’s primary bedroom. The feel is unmistakably firm—more “flat and stable” than “hug and sink.” On my back, my spine stayed straight and my lower back felt supported. On my side, my shoulder stayed higher on the surface, and I felt pressure build during longer stretches.
Marcus reacted differently. On his stomach, his hips barely dipped, which kept him aligned. He also reported less trapped warmth than he usually feels on thicker, slower foam beds.
Jenna tested it with her partner and described the bed as firm but stable. She felt the initial impact when someone climbed in, but the movement faded quickly. Edge sitting felt reliable when she used the side to put on shoes.
AS1 fits a specific sleeper profile. If you mostly sleep on your back or stomach and you like a firm, “on top” feel, it can be a strong match. Many side sleepers—especially lighter bodies—will want more cushion.
Pros & Cons
| Pros | Cons |
|---|---|
| Very firm, stable support that holds hips and lower back level | Too firm for most side sleepers, especially lighter bodies |
| Minimal sink keeps movement easy for back and stomach sleepers | Can feel unforgiving during long reading or lounging sessions |
| Strong edge behavior for an all-foam bed | Less contour may aggravate shoulder or hip sensitivity |
| Motion stays controlled for couples who dislike bounce | Not ideal for people seeking plush comfort |

Amerisleep AS2
Our Testing Experience
AS2 felt like the point where the lineup becomes more forgiving without turning soft. Compared with AS1, the extra thickness and the HIVE zoned transition layer added a subtle cradle under my shoulders while still keeping my lower back supported.
Marcus treated AS2 as his back-sleeping candidate. He noticed the zoning under his hips right away and said it helped keep his pelvis from dropping. On his side, he still felt some shoulder pressure, but it was less pronounced than on AS1.
Mia described AS2 as supportive on her back but still a little firm at the shoulder when she stayed on her side. Jenna rated motion isolation very high and felt comfortable using most of the mattress width near the edges.
AS2 is the model I’d point to first for back-focused sleepers who want medium-firm structure and clear lumbar support.
Pros & Cons
| Pros | Cons |
|---|---|
| Clear lumbar support from the HIVE zoned transition layer | Can still feel firm on shoulders for lightweight side sleepers |
| Balanced firmness for many back and combination sleepers | Heavier stomach sleepers may want even firmer support |
| Strong motion isolation for couples | Plush-mattress fans may find it too structured |
| Good edge stability for sitting and sleeping near the perimeter | Higher cost than AS1 within the lineup |
Details
- Type: All-foam mattress with Bio-Pur comfort and HIVE zoned transition
- Profile: About 12 inches thick
- Comfort Layer: Around 2 inches of Bio-Pur foam
- Transition Layer: Roughly 3 inches of HIVE zoning
- Support Core: About 7 inches of Bio-Core foam

| Value | 4.4 | Mid-range pricing for strong back support. |
| Overall Score | 4.4 / 5 | Excellent for back-focused sleepers who want medium-firm structure. |
Amerisleep AS3
Our Testing Experience
AS3 was the easiest model for our group to agree on. On my first night, I stayed on my side for long stretches without waking up to hip or shoulder complaints. The thicker Bio-Pur comfort layer softened the surface, while the transition layer still pushed back under my midsection.
Mia treated AS3 as her baseline because it gave her pressure relief without feeling “stuck.” Marcus felt more sink than on AS2, which he noticed most on his stomach. Jenna liked the low motion transfer and the easier repositioning compared with slower foam beds.
For me, AS3 was the most balanced: supportive enough on my back, comfortable enough on my side, and quiet enough for shared sleep.
Pros & Cons
| Pros | Cons |
|---|---|
| Strong balance between contour and support across many body types | Heavy stomach sleepers may want firmer support for long nights |
| Great pressure relief for side sleepers without deep sink | People craving ultra-plush softness may prefer AS5 |
| Excellent motion isolation and easy repositioning for couples | Edge sitting feels softer than AS1 and AS2 during long sessions |
| Widely appealing medium feel works for many sleeper profiles | Higher cost than AS1 within the lineup |
Details
- Type: All-foam mattress using thicker Bio-Pur comfort over zoned transition foam
- Profile: About 12 inches
- Comfort Layer: Around 3 inches of Bio-Pur foam
- Support Core: Around 7 inches of Bio-Core foam
- Firmness Feel: Medium, near 6 on our scale
- Trial Period: About 100 nights
- Warranty: Up to 20 years (limited)
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.5 | Kept spines level for average-weight back and combo sleepers. |
| Pressure Relief | 4.6 | Excellent shoulder and hip comfort for side sleeping. |
| Cooling | 4.2 | Neutral temperature for our group. |
| Motion Isolation | 4.6 | Partner movements stayed muted. |
| Responsiveness | 4.1 | Easy to roll without fighting deep foam. |
| Edge Support | 4.1 | Usable near the edge with mild compression. |
| Durability | 4.5 | Solid structure; softer top may imprint sooner under heavy use. |
| Off-Gassing | 3.9 | Moderate smell that cleared with airing. |
| Value | 4.3 | Higher cost than AS1, but versatility justified the step-up. |
| Overall Score | 4.5 / 5 | Most balanced Amerisleep option in our rotation. |
Amerisleep AS5
Our Testing Experience
AS5 is the plush specialist. It expanded into a noticeably taller bed, and you feel the deeper cradle immediately when you sit down. On my side, shoulder pressure eased quickly. During long lounging sessions, it felt indulgent without collapsing under my lower back.
Mia loved the extra cushion and reported fewer pressure-related wake-ups. Marcus enjoyed it for short comfort sessions but felt his hips sank too deeply for overnight stomach sleeping and, at times, for back sleeping.
Jenna rated AS5 as the quietest mattress for motion. The deeper cradle required a little more effort to reposition than AS3, but the Active Flex layer helped it avoid that “stuck” feeling.
If you want plush pressure relief—especially as a side sleeper—AS5 is the clear standout. If you need a firmer “on top” feel, the other models will fit more naturally.
Pros & Cons
| Pros | Cons |
|---|---|
| Deep pressure relief through thick comfort layers | Too soft for heavier stomach sleepers who need firm hip support |
| Extremely strong motion isolation for couples | Softer upper foams may show impressions sooner with heavy use |
| Plush, cushioned side-sleep comfort | Higher price point within the lineup |
| Active Flex adds responsiveness to a plush build | Edge sitting feels softer due to deeper comfort system |
Details
- Type: All-foam mattress with a thicker comfort system and Active Flex layer
- Profile: Roughly 14 inches thick
- Comfort System: Bio-Pur plus Active Flex over a zoned transition layer
- Support Core: Bio-Core high-density foam
- Firmness Feel: Plush, around 4–4.5 on our scale
- Trial Period: About 100 nights
- Warranty: Up to 20 years (limited)
Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.0 | Adequate for side sleepers; deeper sink for heavier stomach sleepers. |
| Pressure Relief | 4.8 | Outstanding cushion for shoulders and hips. |
| Cooling | 4.1 | Neutral overall; heavier bodies may feel warmer due to deeper cradle. |
| Motion Isolation | 4.7 | Thick foam stack nearly erased partner motion. |
| Responsiveness | 4.2 | Active Flex helped prevent a stuck-in-foam feel. |
| Edge Support | 3.9 | Fine for lying near the edge; softer for long sitting. |
| Durability | 4.4 | High-quality foams; softer top may compress earlier under heavy loads. |
| Off-Gassing | 3.8 | Odor lingered slightly longer than firmer models. |
| Value | 3.9 | Higher price justified mainly for plush comfort priorities. |
| Overall Score | 4.4 / 5 | Luxurious pick for side sleepers who want maximum pressure relief. |
Compare Performance Scores of These Mattresses
| Mattress | Overall Score | Support | Pressure Relief | Cooling | Motion Isolation | Durability | Responsiveness |
|---|---|---|---|---|---|---|---|
| Amerisleep AS1 | 4.3 | 4.8 | 3.4 | 4.0 | 4.5 | 4.6 | 3.8 |
| Amerisleep AS2 | 4.4 | 4.7 | 4.0 | 4.1 | 4.5 | 4.6 | 4.0 |

| Amerisleep AS5 | 4.4 | 4.0 | 4.8 | 4.1 | 4.7 | 4.4 | 4.2 |
In our rotation, AS3 was the most balanced option. AS1 and AS2 lean toward firmer, more “structured” support, while AS5 is built for deeper cushioning and quiet motion control. The right pick usually comes down to how often you sleep on your side versus how much you need firm hip support for back or stomach sleeping.
Best Picks
- Best for most sleepers: Amerisleep AS3 — The most consistent blend of pressure relief and support across our testers, with strong motion control for shared sleep.
- Best firm pick for back-focused sleepers: Amerisleep AS2 — Medium-firm structure with noticeable lumbar support from zoning.
- Best plush pick for side sleepers: Amerisleep AS5 — Deep cushioning at the shoulders and hips with standout motion isolation.
How to Choose the Amerisleep Mattress?
Start with body weight and sleep position. If you’re a lighter side sleeper, pressure relief usually matters more than raw support. In our group, AS3 and AS5 were the best fit for that profile. For broader context, see best mattresses for lightweight sleepers and best mattresses for side sleepers.
If you spend most of your night on your back, look for a firmer midsection and steady lumbar support. That’s where AS2 tended to outperform for our heavier tester, while AS3 offered a slightly softer cushion for mixed positions. If you want other back-friendly options, compare best mattresses for back sleepers.
Hot sleepers often prefer less sink. Marcus did best on AS1 and AS2 because the firmer surface kept him more “on top” of the foam. If overheating is a priority, compare strategies in best beds for hot sleepers and learn more about mattress breathability.
Couples should prioritize motion isolation and usable edge space. AS3 and AS5 muted movement the best, while AS1 and AS2 felt steadier at the edge for sitting. For deeper context, see best mattresses for couples.

Limitations
As a group, these all-foam models won’t fit every sleeper. Very heavy sleepers well above 250 pounds who want strong bounce and spring lift may prefer a hybrid design. If that describes you, compare alternatives in best hybrid mattresses.
If you want an extremely rigid surface with almost no give, even AS1 may still feel like “foam.” On the other end, people who want a classic springy feel for quick repositioning won’t get that traditional bounce here.
Pricing tends to sit in a mid-to-upper range for online foam beds. If budget is the main constraint, you may want to compare with affordable mattresses and decide which features you can comfortably give up.
