Does The Amerisleep As3 Sleep Hotter Than The As2? Temperature FAQ Guide

If you’re comparing these two mattresses, it’s natural to wonder: does the Amerisleep AS3 sleep hotter than the AS2, or will they feel about the same? For many sleepers, temperature can be just as important as firmness or support, so understanding how these models differ in warmth can help you choose more confidently.

Below, we break down how mattress design, firmness, and materials affect heat, and what that can mean for your experience with these two options.

Does the Amerisleep AS3 Really Sleep Hotter Than the AS2?

There is no universal, one-size-fits-all answer, because how warm a mattress feels depends on your body type, sleep position, bedroom environment, and bedding. However, from a design perspective:

The AS3 is typically a medium-feel mattress with more cushioning.
The AS2 is usually a firmer mattress with a slightly thinner comfort layer.

Because of this, some sleepers may perceive the AS3 as a bit warmer than the AS2, mainly due to deeper body contouring and closer contact with the surface. More contouring can slightly reduce airflow around your body, which may trap a bit more warmth for some people.

That said, both are designed with breathable, comfort-focused construction. For many sleepers, the temperature difference between them is subtle or not noticeable at all.

Why Might One Mattress Feel Hotter Than Another?

To understand “does the Amerisleep AS3 sleep hotter than the AS2,” it helps to know what actually makes a mattress feel warm or cool.

1. Comfort Layer Thickness and Contouring

Thicker, plusher comfort layers allow you to sink in more.
Firmer, thinner comfort layers keep you more elevated “on top” of the mattress.

When you sink in deeper:

More of your body is in contact with the surface.
Air circulation around your sides and back can decrease.
This can make the mattress feel slightly warmer to heat-sensitive sleepers.

Because the AS3 tends to be more contouring than the AS2, some users may experience more of that “hugged” feeling, which can translate to a bit more warmth.

2. Material Response and Pressure Relief

Both mattresses are designed to relieve pressure, but they do so with different firmness levels. A more pressure-relieving surface (often like the AS3) can:

Cradle joints and curves.
Hold body heat closer to the surface.
Feel warmer if you’re already a naturally hot sleeper.

A slightly firmer option (often like the AS2) keeps more of your body above the surface, which may feel a touch cooler for some individuals.

How Much Does Sleeper Type Affect Heat?

Even with the same mattress, two people can report totally different temperature experiences.

Body Type and Weight

Heavier sleepers may sink deeper into a softer bed, potentially noticing more warmth on a model like the AS3.
Lighter sleepers may not compress the mattress as much and could feel very little difference between AS2 and AS3 in terms of heat.

Sleeping Position

Side sleepers often prefer more cushioning (similar to the feel of the AS3) and may notice a slightly warmer, more “enveloped” sensation.
Back and stomach sleepers who stay more on the surface (similar to the feel of the AS2) might perceive a bit more airflow and a touch more coolness.

Bedding and Room Conditions

Regardless of the mattress:

Heavy comforters, flannel sheets, or warm room temperatures can make any bed feel hot.
Lightweight, breathable bedding and good airflow in the room can make both the AS2 and AS3 feel more temperature-neutral.

Does the Amerisleep AS3 Sleep Hotter Than the AS2 for All Sleepers?

Not necessarily. Many people find both models to be broadly similar in temperature, especially when using breathable bedding. The perceived difference often comes down to:

How deeply you sink into the AS3.
How firmly you’re supported on the AS2.
How sensitive you are to warmth at night.

For a heat-sensitive sleeper who sinks deeply into softer mattresses, the AS3 might feel somewhat warmer than the AS2. For a sleeper who doesn’t compress the mattress as much, the difference may be minimal.

What Else Should You Consider If You Sleep Hot?

If “does the Amerisleep AS3 sleep hotter than the AS2” is your main concern, also keep these general points in mind:

Firmness preference: Choosing a firmness that keeps you from sinking too deeply can help with perceived temperature.
Bedding choices: Lightweight sheets, breathable protectors, and non-insulating comforters can have a strong impact on how warm you feel.
Room environment: Airflow, fan use, and thermostat settings often make more difference than small design changes between similar mattresses.
Sleepwear: Thicker or synthetic sleepwear can trap heat even if the mattress itself is relatively neutral.

✅ Quick Mattress Takeaways

Key points consumers should understand about “Does the Amerisleep AS3 Sleep Hotter Than The AS2”:

Design difference: The AS3 generally feels plusher, and the AS2 feels firmer; this firmness difference can slightly affect temperature perception.
Contour vs. airflow: Deeper contouring on the AS3 can feel a bit warmer to some sleepers due to more body contact and less airflow.
Subtle differences: Many sleepers experience only a small or no noticeable temperature difference between the two models.
Your body matters: Body weight, sleeping position, and heat sensitivity often influence warmth more than the model choice alone.
Environment counts: Bedding, sleepwear, and bedroom temperature can easily outweigh any minor temperature differences between the AS2 and AS3.

If you’re sensitive to heat, it can be useful to think beyond just “does the Amerisleep AS3 sleep hotter than the AS2” and look at your entire sleep setup. Evaluating firmness, bedding, and room conditions together will give you a more accurate sense of how warm or cool either mattress is likely to feel for you.
