Siena Mattress Overview

The Siena mattress is a five-layer, all-foam mattress that’s perfect for cost-conscious shoppers who aren’t willing to cut corners on the essentials. Featuring three full layers of high grade foam designed to promote proper spinal alignment and pressure point relief, plus a breathable top cover that keeps the temperature just right, the Siena delivers a sleep experience just as blissful as other top mattresses—but without the sticker shock.

Siena Mattress Construction

The Siena mattress is made up of five carefully constructed layers that all work together to provide the right balance of cushion and support.

Here’s what you can expect from each layer:

Layer 1: Cooling Poly-Blend Top Cover with Polyethylene

This top-most layer is all about creating a comfortable sleep experience. It’s ultra soft and breathable, releasing heat and keeping you cool as you sleep.

Layer 2: Responsive Memory Foam

This 2.5-inch layer of ultra comfortable gel memory foam adapts to your unique body shape and size, cradling its contours and providing pressure relief for your joints.

Layer 3: Body Supporting Layer

Made of a denser polyfoam, this 2-inch layer of transition foam provides extra cushion, which means extra support. It also includes a special ripple that increases the breathability of the mattress.

Layer 4: Foundational Foam

This 5.5-inch layer of supportive polyfoam serves as a sturdy base for all of the comfort layers above it, so they can continue doing their job—keeping you comfortable as you drift off to dreamland.

Layer 5: Shift-Resistant Lower Cover

This layer ensures that your mattress stays put, no matter how much you turn, roll or even jump on it.


The Siena has met all CertiPUR-US® standards for materials, emissions, product durability and performance, which means it is void of ozone depleting materials, mercury, lead, formaldehyde, phthalates and other harmful compounds. 

Siena Mattress Type

The Siena mattress is a medium-firm, all-foam mattress designed to provide optimal spinal alignment, pressure point relief and temperature regulation.

Ages Suited For

The Siena mattress is a great mattress for all age levels, although it is better suited to certain sleep positions and body weights (see section below).

Sleeper Types Suited For

The Siena mattress is a great choice for almost all sleepers. Here’s more information on how the Siena performs, according to sleep position:

Side Sleepers:

Side sleepers require a mattress that has enough cushion to cradle their hips and shoulders, and enough support to promote proper spinal alignment. The Siena’s all-foam construction and medium-level firmness strikes the perfect balance between the two, and ensures your bodyweight is evenly distributed, alleviating pressure on your joints.

Back Sleepers:

For back sleepers, keeping the spine in proper alignment is of utmost importance. This means the ideal mattress will have some give but not enough to allow sinkage. The Siena’s medium firm feel, pressure-relieving memory foam and polyfoam support core all work together to provide just the right amount of support for back sleepers.

Stomach Sleepers:

Stomach sleepers need a mattress that will prevent their midsection from sinking in, which can cause an unnatural, unhealthy bend in the spine. The dense foam and medium firmness of the Siena provides a good deal of support—enough for a sleeper up to about 230 pounds. Sleepers with larger midsections may wish to explore a firmer mattress to prevent sinkage.

Firmness Level

On a scale of one to 10, the Siena mattress is rated a 6.5, which is considered medium firm. Medium firm mattresses are very popular since they provide an appealing combination of support and cushion.

How to Get the Siena Mattress

You can purchase the Siena mattress online or by calling their customer service phone number. The mattress is available in Twin, Twin XL, Full, Queen, King and California King sizes.

Siena Mattress Cost and Discounts

The Siena mattress sets itself apart with its high quality materials, impeccable construction and extremely affordable pricing. The exact cost of your Siena mattress will depend on the size you choose as well as the promotions running at the time of your purchase. Here’s a range of prices you can expect:  

Twin: $299-$499
Twin XL: $399-$599
Full: $449-$649
Queen: $499-$699
King: $599-$799
California King: $599-$799

Siena frequently runs promotions that make their mattresses even more affordable. Keep an eye on their website around major holidays as they often have sales during these times. 

Siena Mattress Shipping

Siena mattresses are shipped for free via FedEx or UPS Ground from one of the company’s many distribution centers across the United States. It typically takes between two and five business days from when you place your order for your mattress to arrive.

Once your mattress arrives, it’s extremely easy to set up—just slide the compressed mattress out of the box and put it on your bed. As you remove the final layer of packaging, the mattress will expand to fill your bed (just give it at least three hours before sleeping on it).

Siena Mattress Performance

Now that we’ve covered the construction of the Siena mattress, here’s an in-depth look at how it performs in several key areas:

Motion Isolation

The Siena is an all-foam mattress, which means it doesn’t contain any bouncy springs or coils, which are often to blame for the movement you feel when your sleeping companion rolls over or gets up in the middle of the night. The Siena’s foam construction isolates motion and reduces the impact of even the most active sleeper.

Pressure Relief

If you suffer from aching joints, the Siena mattress is a great choice. The responsive, all-foam construction keeps your weight evenly distributed, and for most people, relieves pressure on your hips, shoulders and knees. Note that if you’re a side sleeper under 130 pounds, you may find that this mattress is a bit too firm to provide you with adequate pressure point relief—you may need a softer mattress that has more give to get the relief you’re looking for.

Temperature Control

Memory foam mattresses are often so dense, they restrict airflow and cause heat retention. The engineers at Siena combatted this by incorporating a gel memory foam layer, which helps wick away excess body heat, and adding air pockets between the layers to enable breathability. 

It should be said, though, that the Siena still absorbs some body heat, so if you’re especially sensitive to heat, you may want to consider a model with coils as these tend to enable more airflow.

Edge Support

Although the Siena doesn’t contain a reinforced perimeter, it’s a fairly firm mattress with a sturdy core, so unless you have a hard time getting in and out of bed, you’ll likely find the edge support sufficient. 

Ease of Movement

The Siena was designed to relieve pressure on the joints. It does this by closely contouring to each sleeper’s unique body shape and size. Some sleepers find that this can inhibit movement. But  most find that the polyfoam transitional layer and the support core of the mattress positioned under the memory foam layer help prevent them from feeling stuck.


The Siena mattress is built to last. It contains high-density foam that can withstand a great deal of wear and tear, and it doesn’t contain any coils or springs, which tend to wear down with use.


Since the Siena mattress does not contain springs or coils, which tend to squeak as they age, you don’t have to worry about noise—the Siena is nice and quiet, just how a mattress should be.


The Siena mattress is designed to respond to your body, providing hug-like support to all your unique curves and angles. But that responsiveness might be a deterrent for couples, since it can inhibit movement. The mattress’ lack of bounce may also be a drawback for those seeking the best mattress for sex. That aside, the Siena is a quiet mattress that doesn’t contain any coils so you won’t have to worry about it squeaking, and it’s slip-proof, so it won’t slide around or move when you do.


The term “off-gassing” refers to the chemical-like odor that is often released when compressed memory foam mattresses are removed from their packaging. It’s generally considered harmless, but can be unpleasant and even irritating to those with respiratory issues or odor sensitivities. 

The experts at Siena have worked to minimize off-gassing by choosing high quality materials, but if you do notice an odor after unrolling your mattress, simply opening a window and allowing your mattress to breathe for a bit should take care of it.

Siena vs Other Mattresses

Now that we’ve covered all there is to know about the Siena mattress, let’s compare it to another popular mattress brand, Nectar.

Siena Mattress vs. Nectar Mattress

Both the Siena and Nectar mattresses are great choices for people who want a medium-firm memory foam mattress that is equal parts comfortable and supportive. The Nectar will cost you slightly more—at the time of this review, the Nectar is about $300 more. But Nectar comes with a longer sleep trial and warranty than the Siena. Here’s a look at the differences:

Siena Nectar
Sleep Trial 180 Nights 365 Nights
Warranty 10 Years Forever

Siena Mattress Company Information

Siena is a subsidiary of Resident Home, a family of mattress brands that includes Nectar, DreamCloud and Awara. The newcomer made its debut in March 2022, and sells an impressive variety of sleep necessities and accessories like bed bases, sheets, pillows and mattress protectors—all at very reasonable price points.

Customer Service Information

Siena offers a convenient Live Chat feature right on their website and, unlike other companies, connects you with a real person. You can also reach a Siena customer service representative by phone (844-996-4687) or via email at [email protected].

Trial Period

Siena offers a 180-night sleep trial, which means you get that many nights to test it out. If, before the 180th day, you decide the mattress just isn’t the right fit for you, you can simply contact a customer service representative to initiate a return. Siena does recommend waiting at least 30 days before making a final decision since it can take that long to adjust to a new mattress—especially if it’s your first memory foam model.

Warranty Policy

Siena offers a generous 10-year warranty, which means that if you notice any defects at any point in the first 10 years after your purchase, you may be eligible to receive a new mattress. Simply reach out to a customer service representative to file a claim. 

If you’ve had your mattress for more than 10 years and discover a manufacturing flaw, Siena will repair your mattress for you.

Bottom Line

The Siena mattress is a great choice for people who want a high quality, all-foam mattress that provides excellent support and pressure relief, but don’t want to spend extra for unnecessary features and frills. It’s made of high-quality materials and is backed by a 180-night sleep trial and 10-year warranty.


How to clean Siena mattress?

For light spills and stains, spot clean your mattress cover with a damp washcloth and mild detergent or hand soap. For larger or deeper stains, an upholstery cleaner or cleaning device can be used. It’s crucial that you don’t remove the mattress cover or allow liquid to reach the underlying foam layers as it can cause damage and invalidate your warranty. 

Siena sells water resistant mattress protectors, which are a great investment if you’re worried about stains and spills. Unlike the mattress cover, mattress protectors can be removed and washed.

How long does Siena mattress last?

The short answer is that a Siena mattress should last you around 10 years. However, this can vary depending on how frequently you use it and how well you take care of it.

Here are a few tips to help you get the most out of your mattress and extend its lifespan:

 – Use a mattress protector: This will help keep dust, dirt and other particles from getting embedded into the fabric of your mattress and causing wear and tear.

 – Avoid spills: Try to keep food and drinks away from your mattress to prevent stains. If something does happen to spill, be sure to clean it up right away.

What is the difference between Siena and Nectar?

The Siena and Nectar mattress are both medium firm memory foam mattresses that come with breathable, cooling covers for advanced temperature regulation. The Nectar is slightly more expensive than the Siena, but comes with a 365-night sleep trial and a Forever Warranty, compared to Siena’s 180-night trial and 10-year warranty.

Who makes the Siena mattress?

The Siena bed-in-a-box was created by Resident Home, the parent company to Nectar Sleep, manufacturer of the Nectar Memory Foam mattress.
