The Siena Memory Foam Mattress doesn’t have many bells and whistles, but it includes contouring memory foam that adapts to the body to help cushion pressure points. It is also far more affordable than many comparable mattresses, which makes it an intriguing option for shoppers on a budget. 

We wanted to see just how well this mattress matched up against other all-foam models, so we brought it into our Test Lab for an in-depth breakdown. We’ll tell you about what we found and cover all the other key details that can help you decide whether the Siena Memory Foam Mattress suits your needs.

Testing Team Takeaways

To test the Siena Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

Side sleeper

Has too many dogs in the bed

I thought the Siena’s performance was solid, especially for a low-cost mattress. I didn’t feel much pressure around my hips and shoulders, which is one of the most important things for side sleepers like me.

Side and back sleeper

Sleeps with a weighted blanket

The Siena felt comfortable when I was on my side, but it wasn’t nearly as supportive when I was on my back or stomach. I think it’s serviceable but not ideal for combination sleepers.

The support and pressure relief was good, but I felt way too hot. Ultimately, the heat buildup was enough to pretty seriously affect my comfort.

Side Sleepers

The medium firm (6) feel of the Siena Memory Foam Mattress best accommodates side sleepers who weigh between 130 pounds and 230 pounds. For these sleepers, the memory foam comfortably contours to the hips and shoulders to keep the spine in a neutral position.

The Siena also works for side sleepers under 130 pounds, but some find it to be a bit too firm. In contrast, side sleepers who weigh more than 230 pounds will typically find this mattress to permit too much sinkage.

Back Sleepers

The back sleepers on our testing team that weigh over 130 pounds didn’t love the Siena Memory Foam Mattress. Most of them felt that the mattress was too soft, which reduced support for the lumbar spine. This lack of firmness was most significant for back sleepers over 230 pounds. 

Some back sleepers who weigh less than 130 pounds said that the Siena was acceptable but not optimal. They were able to get a base level of support but still said that they’d prefer a firmer mattress.

Stomach Sleepers

The Siena Memory Foam Mattress isn’t well-suited to most stomach sleepers. Virtually everyone in our testing said the mattress was too soft and had too much contouring to provide adequate support to people who primarily sleep on their stomachs.

Excess sinkage can cause the midsection to sink too far into the top layers, pulling the spine into a misaligned position. This is a problem for stomach sleepers on the Siena Mattress, especially those who weigh more than 130 pounds.

Mattress Performance

In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.

Motion Isolation

7.5/10

“I didn’t notice many vibrations from the other side of the mattress. The memory foam seemed to do its job and keep motion transfer to a minimum.” – Jackson

Our testing found that the Siena Memory Foam Mattress lets you sleep soundly, even if there’s movement on the other side of the mattress.

Although the motion isolation isn’t perfect, the top layer of memory foam contains most vibrations. This makes the Siena effective for people who share the bed.

Pressure Relief

7.5/10

“The Siena’s memory foam did a nice job of reducing pressure around my hips and shoulders when sleeping on my side, but it wasn’t as effective in other sleeping positions. The memory foam layer is also relatively thin, so it might lack pressure relief for people with a higher body weight.” – Logan

The 2-inch layer of memory foam in the Siena Mattress contours to the body, cushioning the heaviest areas. This helps relieve pressure, including around the hips and shoulders.

That said, sleepers over 230 pounds may find that the foam is too soft or too thin to properly cushion their body. Pressure relief from this mattress is also limited for back and stomach sleepers.

Temperature Control

5/10

“Heat buildup was a real problem for me on this mattress. The hug of the memory foam seemed to cause heat to collect around me, and it was enough to interfere with my sleep.” – Brad

Our testers found that heat retention was a serious issue on the Siena Memory Foam Mattress. Even though it’s infused with gel beads, the memory foam collects heat. Its close contouring reduces airflow over the skin, making it harder for your body to cool itself down.

While this may not be an issue for people who run cold, it makes the Siena Mattress a poor fit for those who sleep hot.

Edge Support

6/10

“You’ll definitely notice the difference between sitting in the middle of this mattress and sitting on the edge. The foam compresses a lot, and while it wasn’t a big problem for me, it might feel unstable to some people.” – Jackson

The Siena Memory Foam Mattress offers average or just below-average edge support. You can feel the foam sink deeply around the perimeter, but it doesn’t completely give out beneath you.

Based on our testing team’s experience, the level of edge support is comparable to other low-cost memory foam mattresses. It may be a concern if you frequently sit on the edge of the bed, but it’s not a dealbreaker for most people.

Ease of Movement

5/10

“Along with heat retention, another downside of the hug of memory foam is how it can restrict motion. That was my experience on the Siena Memory Foam Mattress. While I was comfortable on my side, I felt like I was fighting the mattress when I wanted to adjust my posture.” – Brad

Changing sleeping positions can be tricky on the Siena Memory Foam Mattress. There’s almost no bounce, and the conforming foam can create a barrier to movement.

For some sleepers, this is a worthwhile tradeoff in order to get the pressure relief of memory foam. But restricted movement may be an issue for combination sleepers and anyone with strength or mobility issues.

Off-Gassing

5.5/10

“For about 48 hours, it was pretty clear that there was a new mattress in my bedroom. The foams give off a noticeable scent, but I turned on a fan, which seemed to help it dissipate.” – Logan

We found significant off-gassing from the Siena Mattress. This is normal for a mattress made entirely of foam, and it’s important to note that off-gassing likely doesn’t create any health risks. However, it does mean that there’s a noticeable smell that can last for a few days after you first set up the mattress.

Siena Mattress Review Breakdown

The Siena Mattress has a straightforward, all-foam design. It is 10 inches tall and has a firmness level of medium firm (6).

The cover of the mattress is made with soft polyester fabric. Inside, there are three layers of foam.

The top layer is made with 2 inches of gel-infused memory foam. This layer is the source of pressure relief and motion isolation, and the gel infusion is intended to keep the material from collecting heat during the night.

The second layer is 4 inches and made of polyfoam that supports the memory foam layer, providing pushback and limiting sinkage. The foam has an egg-crate shape to enable more cooling airflow.

The bottom layer is 4 inches of high-density polyfoam. This material serves as the base or support core of the Siena Mattress.
