Purple vs. Amerisleep Mattress Comparison
The Amerisleep AS3 mattress comes in an all-foam version and a hybrid version with pocketed coils instead of support foam. We’re focusing on the all-foam version in this comparison, which is made entirely of polyfoam. In contrast, the original Purple mattress has the Purple Grid—a unique top layer made from a gel-like material called Hyper-Elastic Polymer.
Both mattresses work well for lightweight (< 130 lbs) and average-weight (130–230 lbs) back sleepers and average-weight side sleepers. The AS3 is a better fit for stomach sleepers, though only those with lightweight body types. Neither is the ideal for those with heavyweight body types (> 230 lbs). If you sleep hot, go with the Purple, since the top layer is naturally cooling.
Comparing the Amerisleep Mattress & Purple Mattress
Key Differences
- Feel: The Purple Grid (used in all Purple mattresses) relieves pressure points without allowing the sleeper to sink too far into the mattress. Some say it feels like floating on top of the mattress. The AS3 has a balanced foam feel that’s moderately cushioning.
- Temperature: Both companies claim that their mattresses sleep cool, but the Purple Grid promotes steadier airflow than the all-foam version of the AS3. Even the hybrid AS3 has below-average breathability for a mattress with a coil support layer.
- Price: The Purple mattress offers an innovative design for a reasonable price point. The AS3 has a relatively traditional foam design, yet is more expensive.
Key Similarities
- Body Types: Both offer the best spinal alignment and comfort for lightweight or average-weight body types, regardless of whether you’re a side, back, or stomach sleeper.
- Ease of Movement: Both beds are fairly easy to move around on, making them a good mattresses for combination sleepers.
- Ideal for Back Sleepers: The medium to medium-firm feel of the Purple and AS3 make them great mattresses for back sleepers, particularly those under 230 lbs.

Who the Amerisleep Mattress is Best For
- Lightweight and average-weight sleepers: The AS3 strikes a balance between support and comfort for those under 230 lbs by cradling pressure points without too much sinkage.
- All sleep positions: The bed’s medium firmness level is just soft enough for average-weight side sleepers and just firm enough for back sleepers and lightweight stomach sleepers.
- Combo Sleepers: While traditional memory foam beds might feel overly-cushioning, the top foam layer on the Amerisleep is a more responsive memory foam, so you won’t feel stuck in the mattress.
Not Best For…
- Heavyweight sleepers: The all-foam version of the AS3 isn’t quite supportive enough for heavyweight individuals and couples.
- People who want a traditional memory foam feel: If you enjoy the feel of a traditional memory foam mattress, which is slow to respond and sinks deeply underneath the body, you won’t find what you’re looking for in the AS3.
- People who sleep hot: The AS3 doesn’t offer adequate cooling features for super-hot sleepers. The top layer of Bio-Pur foam tends to absorb heat, so the bed sleeps temperature neutral instead of cool.

Who the Purple Mattress is Best For
- Side and back sleepers: The Purple distributes body weight evenly, making it one of the best mattresses for back sleepers. Side sleepers will also find great contouring at the hips and shoulders.
- Sleepers who enjoy a unique, floating feel: The top comfort layer of the Purple Original is a thick slab of Hyper-Elastic Polymer, which has a similar feel to the gel material used in shoe insoles. The result is a responsive bed that’s soft, yet firm, with a weightless, buoyant feel.
- People who sleep hot: The Purple Grid’s construction allows air to flow through the top layer, so it distributes body heat and sleeps much cooler than the average all-foam bed.
Not be Best For…
- Memory foam lovers: Purple mattress models are unlike anything on the market, and shoppers who purchase this bed expecting the traditional softness, cradling, and sinking of memory foam may not enjoy its unique feel.
- Stomach sleepers: Stomach sleepers find that the middle third of the Purple sags too much, moving the spine out of alignment and potentially causing lower back pain. For better options, see the best mattresses for stomach sleepers.
- Heavyweight sleepers: Heavyweight sleepers may experience sagging and pressure buildup with the Purple. The Purple Hybrid is a better mattress for heavy people, since it has a coil base that provides adequate support.

Amerisleep vs. Purple Performance Differences
Firmness
Both of these mattresses have a mid-range firmness level, but the Purple is medium-firm (6.5/10), while the Amerisleep AS3 is a true medium (5/10). Even so, how they feel varies drastically and will likely be the deciding point for most shoppers. The Purple has a firm, yet comfortable, floating feel, and the Amerisleep feels like a memory foam bed that responds faster to pressure.
Amerisleep Performance By Sleeping Position:
| Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
| Lightweight (< 130 lbs): | 5 | 4 | 2 |
| Average weight (130–230 lbs): | 5 | 3 | 4 |
| Heavyweight (> 230 lbs): | 2 | 2 | 2 |
Purple Performance By Sleeping Position:
| Body Type: | BACK SLEEPERS | STOMACH SLEEPERS | SIDE SLEEPERS |
| Lightweight (< 130 lbs): | 5 | 3 | 4 |
| Average weight (130–230 lbs): | 5 | 2 | 4 |
| Heavyweight (> 230 lbs): | 3 | 1 | 4 |
1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent
Motion Isolation
All-foam beds tend to isolate motion better than other styles, but the Purple, not the AS3, prevents the most motion transfer. The responsive foam on top of the AS3 allows movement to affect the rest of the mattress, while the Purple keeps excessive motion from spreading across the mattress surface. Couples concerned about motion transfer should opt for the Purple or one of the best mattresses for couples.
Edge Support
Support around the perimeter of a mattress is key for sleepers who want to spread out on their bed. It’s also important for couples looking to use the entire surface of the mattress or those who sit on the edge of the bed to get ready for the day.
Edge support is often achieved by denser, thicker foams and tends to be better on innerspring and hybrid mattresses. Neither of these beds earned a perfect score in this category, but the Purple is noticeably more supportive around the edges than the AS3.
Pressure Relief
Pressure relief refers to how well a bed cradles pressure points like the hips and shoulders. The AS3 provides enough body contouring for all sleeping positions, but the Purple’s pressure-relieving ability varies by sleeping position.
Stomach sleepers in particular will find that their torsos sag on the Purple mattress, which can lead to neck and shoulder pain; however, the Purple is the better mattress for side sleepers thanks to adequate pressure relief and even weight distribution that keeps side sleepers’ spines aligned.
Durability
A mattress’s lifespan can usually be predicted by its style and the quality of its materials. Though it’s hard to tell exactly how long different mattresses will last, we predict the AS3 mattress will last about seven years. Purple has not been on the market long enough to determine the average lifespan of their original mattress, but we’d expect about the same lifespan or longer.
Temperature
The Purple offers better temperature regulation, so it’s the best cooling mattress of the two. The open construction of the Purple Grid allows air to flow through so body heat doesn’t get trapped in the mattress. The AS3’s top layer of memory foam can trap heat, despite its breathable, cooling cover, though it should keep the average sleeper at a neutral temperature.
Amerisleep Mattress Construction
| Cover | Proprietary Cooling Cover |
| Comfort Layer | 3” Bio-Pur Memory Foam |
| Transitional Layer | 2” Polyfoam w/HIVE Technology |
| Support Layer | 7” High-Density Bio-Core Polyfoam |
| Mattress Thickness | 12” |
The Amerisleep AS3 is wrapped in their proprietary Refresh Cooling Cover that can be removed via zipper for cleaning. The top layer is Amerisleep’s exclusive Bio-Pur foam, which is an open-cell (read: breathable) and responsive variation on memory foam.
The second layer is made of polyfoam molded in a honeycomb shape with extra support beneath the hips—this is what Amerisleep calls their HIVE technology. The support core of the AS3 mattress is 7″ of high-density polyfoam that improve the bed’s stability.
Purple Mattress Construction
| Cover | Polyester, Viscose, and Lycra Spandex |
| Comfort Layer | 2” Hyper-Elastic Polymer Grid |
| Transitional Layer | 3.5” High-Density Polyfoam |
| Support Layer | 4” High-Density Polyfoam |
| Mattress Thickness | 9.5” |
The Purple is wrapped in a soft fabric cover that includes Lycra spandex for extra stretch. The top layer is the Purple Grid, made from an exclusive material called Hyper-Elastic Polymer. This material feels like a gel solid—it’s stretchy, temperature neutral, and compresses easily under weight. The Grid is shaped like a waffle, with over a thousand cube-shaped pockets that collapse under weight.
Next up, a high-density polyfoam transitional layer and an even higher-density polyfoam base layer give the mattress its stability and load-bearing capacity.

Our Final Take: Amerisleep vs. Purple
Purple is the clear choice for people who sleep hot or those with a tighter budget. We also recommend it to those who want the support of a medium-firm mattress. The Amerisleep AS3 is better for those who prefer the conforming feel of foam, but who want more responsiveness than traditional memory foam.
Both beds work well for back sleepers under 230 lbs and side sleepers with average body types. The Amerisleep could work for lightweight stomach sleepers, but lightweight side sleepers should opt for the Purple or a softer Amerisleep mattress. No matter which you choose, you’ll get a full 100 days (and nights) to test out your new bed.
