The Sleep Foundation product testing team uses an industry-leading evaluation process paired with real world consumer feedback to come up with objective recommendations so that you can feel confident in your product decisions.
The Siena Mattress delivers comfort and support at an affordable price. Its foam layers contour to the body for pressure relief while maintaining durability and stability. Ideal for budget-conscious sleepers seeking a quality all-foam option.
- Memory foam comfort layer provides pressure relief
- Affordable price-point
- 180-night sleep trial
- Lacks firmness for most sleepers over 230 pounds
- Absorbs too much heat for hot sleepers
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.

TEST LAB RATINGS
How the Siena Memory Foam Scored
Motion Isolation7.5/10
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.
Jeremy Klein, Product Testing Manager: “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.”
Pressure Relief7.5/10
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.
Logan Foley, Executive Product Director: “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.”
Temperature Control5.0/10
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.
Brad Nehring, Product Testing Manager: “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.”
Edge Support6.0/10
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.
Jeremy Klein, Product Testing Manager: “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.”
Ease of Movement5.0/10
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.
Brad Nehring, Product Testing Manager: “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.”
Durability5.5/10
While the Siena Memory Foam mattress excels for affordability and pressure relief, it’s not likely to last much beyond six years because of its construction. It’s all foam, meaning there are no coils to offer sturdy base support. The polyfoam in both the comfort layer and support core help add a bit more stability to the gel-infused memory foam.
HANDS-ON TESTING
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.
Logan Foley
Executive Product Director · 140 lbs. · Side sleeper
140 lbs. · Side sleeper
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.
Brad Nehring
Product Testing Manager · 215 lbs. · Side and back sleeper
215 lbs. · Side and back sleeper
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.
Jeremy Klein
Product Testing Manager · 160 lbs. · Side sleeper
160 lbs. · Side sleeper
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.
Who it Fits
Fit by Sleep Position and Body Weight
Sizes, dimensions and weights
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.

FAQs
Are Siena mattresses good?
Siena is a budget mattress brand, but their beds offer relatively good value for money. Similar to other all-foam beds, the flagship Siena Mattress provides solid pressure relief and motion isolation, though it has a tendency to retain heat and may inhibit movement.
Siena doesn’t share the density of the foams used in its mattresses. However, the low price point suggests the foams may be low-density and therefore less durable than competing brands.
Which is better: Nectar or Siena memory foam mattress?
The Nectar Classic and the Siena Signature Memory Foam Mattress both cater to similar types of sleepers. As memory foam beds, they put the focus on pressure relief and motion isolation, making them well-suited to side sleepers and couples. The Siena is easier on the wallet, but the Nectar is built to last longer and has a slight edge over the Siena in most performance categories.
Both brands also stock other mattresses, although Nectar offers more choice in terms of specialized features like cooling or zoned support.
