We’ll also illustrate what to look for when buying a mattress online.
- Budget-conscious shoppers
- Sleepers who experience sharp pressure points
- People who weigh up to 230 pounds
- Couples who prioritize motion isolation
- Lacks significant edge support
- Absorbs too much heat for hot sleepers
- May be too plush for stomach sleepers over 230 pounds
- Moderate off-gassing when unrolled
Like many other all-foam mattresses, this model isolates motion well. When you shift sleeping positions, the foam layers absorb your movement. This effectively stops motion where it starts and prevents disturbances from traveling across the mattress.
The Siena Mattress’ foam layers offer a full-body hug that evenly disperses your weight and absorbs impact to prevent pressure point discomfort.
The memory foam comfort layer coupled with the polyfoam transitional layer below offer top-notch pressure relief. The mattress suits side sleepers and people who experience joint pain, as it cushions the hips, shoulders, and knees.
Memory foam can be quite dense and restrict airflow, which often leads to heat retention. The Siena has cooling-specific technologies that target this issue. The gel-infused foam and cooling fibers help this model control temperature, though it still absorbs some body heat.
The Siena Memory Foam Mattress does not have a reinforced perimeter or enhanced structure, so it lacks robust edge support. However, its medium firm feel and strong polyfoam support core prevent the edges from sagging too much.
This model’s polyfoam transitional layer and support core keep sleepers from sinking too deeply into the mattress and prevent them from feeling stuck in the bed.
However, the memory foam comfort layer relieves pressure by closely contouring to the sleeper’s body. One drawback to this feature is that it’s slightly more difficult to move around on the bed without compressing the memory foam.
Most couples find that the best beds for sex feature strong edge support and bounce. While this model has good responsiveness and edge support for an all-foam mattress, it doesn’t have the heightened perimeter reinforcement or springiness that some couples enjoy.
Many memory foam and polyfoam products release a chemical-like smell known as off-gassing when they’re unwrapped. While the odor is generally considered harmless, it can be irritating to some people.
The Siena Memory Foam Mattress has an odor after it’s unrolled, but we found that it’s not as strong as many comparable products and that it dissipates quickly.

Sleeping Style and Body Weight
Siena Memory Foam Mattress
Side sleepers who use a mattress that’s too firm often experience discomfort under their hips and shoulders. The Siena Mattress’ medium firm feel is a midrange firmness level that best accommodates side sleepers who weigh between 130 pounds and 230 pounds, though it also suits sleepers above and below that weight range.
The memory foam comfort system cradles the hips and shoulders, providing side sleepers with enough cushioning to prevent pressure points from forming. The polyfoam transitional layer also adapts to your body’s shape and distributes your weight to further alleviate discomfort.
Back sleepers typically need a blend of pressure relief and strong support that keeps their spines evenly aligned. The Siena’s medium firm feel and pressure-relieving memory foam check both those boxes for back sleepers in every weight group, though the mattress is particularly well suited to those under 130 pounds.
Lightweight back sleepers receive sturdy support from the polyfoam support core, which is the ideal density to prevent them from sinking into the mattress. Back sleepers who weigh over 130 pounds may prefer a firmer coil-based model with greater lumbar support.
Stomach sleepers need the strongest support of any sleeper type. A bed that’s too soft allows their midsections to sink into the mattress, causing a U-shaped bend in the spine.
The Siena Mattress offers excellent support for stomach sleepers under 130 pounds and adequate support for those between 130 and 230 pounds. Moderate cushioning keeps the surface from feeling too hard for these groups. Stomach sleepers who weigh more than 230 pounds will likely prefer a firmer mattress that keeps their spines evenly aligned.
Siena Mattress Review Breakdown
The all-foam Siena Mattress is a medium firm (6) model that measures 10 inches tall. The well-rounded mattress features an affordable price-point and balanced feel that successfully blends cushioning and support. The model’s design uses three different foam formulations to provide pressure relief and promote spinal alignment.
The topmost layer consists of 2.5 inches of gel-infused memory foam that adapts to your body’s shape and cradles your joints and pressure points. The gel infusions are intended to keep sleepers cool by drawing excess heat away from the mattress surface.
Next, a transitional layer made from 2 inches of polyfoam contours your body and compresses when you lie on it, enhancing pressure relief. The layer is firmer than the memory foam, which prevents you from sinking too deeply into the mattress. Strategically placed ventilation cuts within the foam allow for increased airflow.
The support core includes 5.5 inches of polyfoam for structure and durability. During our sleep trials, most of our team found this model had robust enough support to keep their spines evenly aligned — except stomach sleepers over 230 pounds, who found it too soft for their comfort.
A polyester cover wraps the mattress. Polyethylene fibers woven directly into the fabric work to regulate temperature by wicking away heat and moisture. The lower part of the cover has a no-slip design that keeps the mattress anchored to your bed’s foundation.
Shoppers can purchase the Siena in six standard sizes including California king. The foam used within the mattress is CertiPUR-US certified, meaning it’s free of harmful chemicals and additives.
Medium Firm (6)
The Siena Memory Foam Mattress has a tri-layer design that incorporates gel-infused memory foam and two different polyfoam formulations. The soft polyester blend cover includes cooling fibers on the surface and a slip-resistant base.

Mattress Prices and Sizing
All-foam mattresses with simple designs tend to be more affordable than intricately made models, and the Siena Mattress is no exception. But while it has a straightforward construction, its materials are higher quality than many budget-friendly models. The manufacturer doesn’t sacrifice unique features for the sake of cutting costs, as the Siena includes several cooling technologies despite its inexpensive price-point.
Many mattresses within the same price range don’t include these extra components and didn’t score as highly in our durability testing, making the Siena a worthwhile choice for shoppers looking for a good deal on a well-made mattress.
Those who need a complete bedroom setup can bundle their mattress purchase with sheets, pillows, and one of Siena’s compatible bed foundations. Financing is available for customers who qualify. The sleep trial and warranty are both generous and transparent.
