Sleep Position Ratings
Amerisleep AS3
The AS3 is ‘Medium’ (5.5), and provides a balance of close conforming and well-reinforced sleeper support. This makes the mattress ideal for sleepers weighing between 130 and 230 pounds, as well as lighter or heavier individuals who like the ‘Medium’ feel.
Side sleepers may also enjoy the AS3, which conforms closely enough to help align the spine and alleviate pressure points that often result from this position. The AS3 provides great motion isolation and does not make any noise when bearing weight. It also sleeps cooler than the average all-foam mattress due to its cotton-blend cover.
TEMPUR-Adapt
Primarily due to its ‘Medium’ (5) feel, the TEMPUR-Adapt has earned the most positive ratings from sleepers in the average weight group (130 to 230 pounds). The mattress conforms closely without sagging or losing support, making it a good choice for back and stomach sleepers.
The memory foam also cushions the hips and shoulders, which helps improve spinal alignment for side sleepers. Those who weigh less than 130 pounds or more than 230 pounds may also find the bed suitable, depending on their comfort preferences.

Mattress Construction
Now let’s take a look at how these mattresses are made. The next table lists firmness, thickness, and composition specs for the Amerisleep AS3 and Tempur-Pedic TEMPUR-Adapt beds. Please note that Tempur-Pedic does not disclose certain specifications for mattresses, including individual layer thicknesses or foam densities.

Cover Composition | Cotton and Polyester Blend | Dual Layer ‘SmartClimate’ Cover | Dual Layer ‘SmartClimate’ Cover |
How Are Amerisleep AS3 Mattresses Built?
The AS3 from Amerisleep is constructed with a 3-inch memory foam comfort layer with a density of 4 PCF. The material offers a ‘Medium’ feel and close conforming, which can improve spinal alignment for sleepers and alleviate pressure points throughout their bodies.
The mattress also has a stretchy cover made from a breathable blend of cotton and polyester, which provides good temperature neutrality.
The AS3’s support core measures 9 inches thick, consisting of a 2-inch transitional polyfoam layer and a 7-inch high-density polyfoam base layer. This relatively thick core reinforces the bed very well, resulting in better sleeper and edge support than many of the AS3’s all-foam competitors.
However, this support core also makes the mattress heavier than average – it weighs 88 pounds in a Queen-size, making it difficult for many owners to lift and rotate as recommended.
How Are Tempur-Pedic Mattresses Built?
The all-foam TEMPUR-Adapt is constructed with two primary layers, a comfort layer of memory foam and a support core of high-density polyfoam. The bed offers a ‘Medium’ feel and close conforming to the sleeper’s body.
It also has a two-layer SmartClimate cover made from cooling fabric. As a result, the all-foam TEMPUR-Adapt and AS3 (with its cotton-polyester cover) offer comparable levels of temperature neutrality. The bed has an 11-inch profile, making it slightly thicker than average.
The hybrid TEMPUR-Adapt shares many similarities with its all-foam counterpart, including cover and comfort layer composition, thickness profile, and firmness setting. The key difference lies in its pocketed coil support core, which makes the hybrid TEMPUR-Adapt more responsive than the foam version. It also sleeps even cooler, thanks to consistent air flow through the coil layer.
