Construction & Design

This Siena Sleep Mattress is made up of three layers of foam out of a total of five layers that work together to provide comfort and support. 

Layers Description
Cover The Siena mattress cover is made from a soft, breathable knit fabric that allows air to flow freely through the mattress. This helps to regulate your body temperature and keep you cool and comfortable throughout the night
Responsive Memory Foam The top layer of the mattress is made from a responsive memory foam, which provides a comfortable and supportive feel while also promoting airflow to help regulate temperature. This layer is designed to contour to the body and relieve pressure points, which can help prevent aches and pains in the morning
Body Supporting Layer Beneath the memory foam layer is a transition layer of polyfoam, which helps to provide additional support and prevent you from sinking too deeply into the mattress. The base layer of the mattress is made from high-density foam, which helps to provide stability and durability to the mattress
Foundational Foam The Siena Mattress foundation is a high-density foundational foam that provides a stable base for the mattress and helps to ensure that you are properly supported throughout the night
Shift-Resistant Lower Cover Lastly, a shift-resistant lower cover makes sure that your mattress stays put, offering you solid resistance against any motion transfer

Is Siena a good mattress?

Considering the Siena Sleep mattress is a newer player on the market, it’s managed to make quite the splash. Based on Siena mattress reviews, the mattress is a solid and affordable choice for sleepers looking for a comfortable and supportive memory foam mattress. It also performs well when we asked the following performance questions:

person on mattress icon

Is the Siena mattress good for pain?

An all-foam construction mattress is often a great option for people with back pain, as it can provide adequate pressure relief. The Siena Mattress is a perfect example of this. Its foam layers allow you to sink into the bed comfortably, while distributing your weight across the mattress, easing pressure points. Additionally, the base layer of high-density foam provides a sturdy foundation that helps keep your spine properly aligned throughout the night.
cooling mattress icon

Are Siena mattresses cooling?

One common issue with memory foam mattresses is that they can retain heat, making them less suitable for hot sleepers. However with the many advancements in mattress technologies, Siena mattresses were designed with cooling in mind. The top layer of gel-infused memory foam helps wick away body heat and keep you cool throughout the night. Air pockets strategically designed between the layers allow the mattress to breathe. Additionally, the breathable cover allows for airflow, further helping to regulate your body temperature.

Siena Mattress Motion Isolation

If you sleep with a partner or a pet, you want a mattress that minimizes motion transfer so that you're not disturbed by each other's movements throughout the night. Based on Siena Sleep reviews, like other memory foam mattresses, it performs well in this regard, as the high-density base layer helps isolate motion and prevents it from transferring across the bed.

Does the Siena Mattress have good Edge Support?

Edge support is important if you like to sit or sleep on the edge of your bed, as it helps prevent you from feeling like you're going to fall off. It’s also a big factor in the feeling of how big the mattress is. A mattress with good edge support can feel significantly larger. The Siena mattress performs fine in this regard thanks to the high-density foam base layer, which helps keep the edges of the mattress firm and supportive.

Are Siena Beds good for Sex?

Many couples consider several factors when choosing a mattress that's conducive to sex. These factors typically include ease of movement, responsiveness and bounce, and temperature regulation. As a memory foam mattress, Siena beds may not be the optimal choice for sex due to the conforming nature of memory foam, which can make it challenging to move around and change positions quickly. Additionally, some couples may find the lack of bounce to be a drawback. However, if you value pressure relief and motion isolation over bounce and responsiveness, the Siena mattress could still be a suitable option for you.

Do Siena Mattresses Emit Off Gassing?

Like most memory foam mattresses, Siena bed in a box may have some off-gassing when first unpacked. This is a normal and harmless process, and any odor should dissipate in 24-72 hours. To speed up the process, you can air out the mattress in a well-ventilated room before using it.

Sleeping Positions

It's always a good idea to consider your own sleep style and preferences when selecting a mattress. Every type of sleeper requires a different experience from their mattress. For example, side sleepers may prefer a slightly softer mattress to cushion their shoulders and hips, while back and stomach sleepers may prefer a firmer mattress for proper hip alignment. In this section of our Siena mattress review, we breakdown each sleeper style:

side sleeper icon
Side Sleepers

Almost all side sleepers of different weights will appreciate the conforming memory foam layers in the Siena mattress. Siena Mattress side sleepers need cushioning for their pressure points, especially in the hips and shoulders and the Siena Mattress’ medium-firm is the perfect balance of support for those key areas. 

Side sleepers who weigh up to 230 lbs will be best accommodated, however plus-sized side sleepers might also enjoy the Siena memory foam mattress if they prefer a softer firmness. 

back sleeper icon
Back Sleepers
The Siena mattress is good for back sleepers who prioritize proper spinal alignment and pressure relief. Its medium-firm feel strikes the perfect balance between being supportive without being too firm or soft. Thanks to the responsive memory foam layers, the mattress offers a solid sleeping surface that minimizes “give” under the sleeper. For back sleepers who weigh up to 130 lbs, the Siena mattress provides the ideal amount of support. For those who weigh between 130 to 230 lbs, the level of support will depend on their preference for firmness. However, those who weigh more than 230 lbs might find the mattress to be too soft and might want to opt for a firmer mattress.
stomach sleeper icon
Stomach Sleepers

Stomach sleepers are notoriously hard to please, as they require a delicate balance of support and comfort from their mattress. When it comes to the Siena mattress, stomach sleepers who prefer a medium-firm surface will be pleased with the even weight distribution it offers. This is because the Siena mattress is designed to support the weight of the hips, preventing them from sinking in and causing misalignment of the spine.

The Siena mattress is ideal for stomach sleepers who weigh under 130 lbs, although it can also be suitable for those between 130 to 230 lbs, depending on their preferences. However, it may not be the best choice for plus-sized sleepers, as it may not provide adequate support for their hips, causing discomfort in their spine.
