What is fiberglass?

A popular type of reinforcing material, fiberglass is made from fine fibers of glass. It is known for its robustness, tenacity, and lightweight structure.

Derived primarily from a type of natural mineral, the production process involves melting it down to manufacture the fibers.

These properties make it an excellent choice for numerous applications ranging from building insulation and thermal protection to automobile bodies, bathtubs, and surfboards.

The strength of fiberglass can be comparable to steel, yet it typically weighs significantly less, making it versatile in use across different industries.

It exhibits resistance to heat, allowing it to sustain in high temperatures without losing its efficacy or performance ability.

Does Siena Mattress Have Fiberglass?

Siena Mattress Performance

When you think of a great mattress, several desirable qualities come to mind. The Siena mattress is renowned for its excellent performance in these areas.

From motion isolation to temperature control, it checks all the boxes and delivers an excellent sleeping experience.

This thorough analysis of the Siena mattress’s features will help you quickly gain a deeper understanding of whether or not this bed is right for you.

Motion Isolation

The Siena mattress performs exceptionally well when it comes to motion isolation. Thanks to its responsive gel memory foam layer, which absorbs movement quite effectively, you won’t feel your partner tossing, turning, or getting in and out of bed.

This feature is particularly beneficial if you or your partner tend to move around a lot during sleep. The design ensures that any movement on one side of the bed does not interfere with the other, providing an undisturbed slumber that lasts through the night.

Pressure Relief

Nothing spells comfort like a mattress that can offer relief from pressure points. The Siena mattress excels here as well. Its top layer of gel-infused memory foam caters explicitly to pressure relief by conforming and contouring to your body shape perfectly.

This strategic configuration allows even weight distribution, relieving potential stress on pressure-prone areas like your hips, shoulders, and lower back.

As a result, those nagging morning aches due to incorrect sleep postures might just become a thing of the past with this cleverly designed comfort provider!

Temperature Control

One key feature designed for their mattresses is temperature control. Their soft cover and responsive gel memory foam work together as a dynamic duo that mitigates excessive heat accumulation while you sleep peacefully.

The ripple design in its layers enhances airflow within the mattress itself, fostering a cool sleep environment and keeping any potential sweat at bay.

Edge Support

The edge of the mattress is more than just a boundary. It serves as an area for sitting, tying shoelaces, or even reading a book.

Here’s where Siena shines again with its impressive edge support. At the same time, many foam mattresses fail to provide satisfactory edge support.

Siena stands out with a strong foundational foam layer that adds extra sturdiness and stability to the edges. You’ll find yourself perched comfortably at your mattress’s border sans any sinking feeling.

Ease of Movement

A good mattress should prioritize the ease of movement as much as it focuses on comfort. With every little detail meticulously planned out, Siena doesn’t disappoint in this regard either.

Its gel-infused memory foam and support foam combine to offer a surface that supports balance and facilitates easy movement across the mattress. This design ensures you won’t face that unwarranted stuck-in-the-bed feeling ever!


Do you know how new cars have that fresh factory smell? Typically, some mattresses give off an odor when newly unpacked – known as “off-gassing.”

Despite being harmless with most beds, it can be somewhat unpleasant. Rest assured, knowing that there are no such issues with the Siena mattress.

One of its critical selling points is how negligible and short-lived this off-gassing process is.

How are Siena mattresses made?

When browsing for your perfect mattress, knowing the ins and outs of its construction can really help you hone in on whether it’s the right fit for your needs.

How are Siena mattresses made?

We’re pulling back the covers and taking a deep dive into how Siena mattresses are made.

Soft, Durable Cover

One of the salient features of Siena mattresses is their soft, durable cover. It’s no secret that an enjoyable sleeping experience largely depends on the very first layer you touch. Constructed with attention to detail, this soft cover lends a luxurious feeling to your night’s rest.

The material used is not only resilient but also very breathable, contributing greatly to a cool and comfortable sleep. This means even during those sultry summer nights, you won’t be sleepless due to discomfort.

Responsive Gel Memory Foam

A key value-add for any mattress is comfort tailored exactly to your body shape and size, and that’s what responsive gel memory foam provides in Siena mattresses.

It’s a 2″ layer of pressure-relieving gel-infused memory foam designed to adapt uniquely to you while contouring delicately around your curves.

This layer works over time, ensuring that every point of your body gets the support it needs without causing unwanted stiffness or pressure points.

Support Foam

If there were an unsung hero in all mattress constructions, support foam would be it. The Siena mattress utilizes four inches of convoluted support foam that goes beyond simple cushioning.

It has been engineered with special ripples that augment airflow within the mattress itself. The improved breathability, coupled with excellent comfort and support, truly makes this feature a standout on its own.

Foundational Foam

Up next is another heavy lifter within the mattress composition foundational foam. No less than four inches thick, this sturdy stability foam layer packs quite a punch when it comes to maintaining structural integrity over time.

Serving as the backbone of the mattress, this element allows the luxe comfort and responsive support layers to do their job without sagging or losing shape. This extremely durable layer ensures your Siena mattress stays a wise investment for years to come.

Shift-Resistant Lower Cover

It’s hard to overlook the advantage of a shift-resistant lower cover. The sturdy bottom layer of any Siena mattress is resistant to movement, keeping all layers intact and perfectly in place.

No carelessly waking up on a skewed mattress anymore. This feature offers the bonus of giving your mattress a clean look by preventing shifting that often happens with regular use.

How can you clean Siena Mattress?

Preserving the longevity and freshness of your Siena mattress isn’t as complex as it might seem. In fact, all it takes is following a few simple steps outlined below.

We’ll guide you through each of them to help extend the life of your Siena mattress while maintaining its supreme comfort.

Check Siena Mattress Care Label

Before you dive into the cleaning process, it’s crucial to refer to the care label on your Siena mattress. This label provides essential instructions tailored specifically for your brand of mattress.

It will include vital cautionary notes about what products and techniques are safe for use with a Siena mattress, giving you the confidence to clean thoroughly without risking damage.

Paying heed to these instructions not only protects you from damaging your beloved mattress but also preserves the warranty that comes with it.

Not adhering to these guidelines might unintentionally void your warranty, leaving you uncovered in case of any potential issues down the line.

Vacuum Regularly With Upholstery Attachment

A critical step in maintaining your mattress includes regular vacuuming using an upholstery attachment. The narrow crevices and textured surface on this attachment make it incredibly effective at extracting dust or any little particles lodged in the fabric.

Vacuuming shouldn’t be reserved for when you see visible dirt on your mattress; regular vacuuming can filter out allergens, dust mites, and other microscopic debris that may accumulate deep within the fabric over time. Keep in mind always to vacuum both sides and underneath your bed for comprehensive cleaning.

Address Spills Immediately

Accidents are inevitable! Maybe it’s a spilled cup of coffee or a pet mishap- either way, time is truly of the essence when dealing with spills.

Your best chance at avoiding a lasting stain lies in tackling spills promptly before they get absorbed into the mattress.

Start by blotting the spilled liquid with a clean, dry cloth or absorbent paper towel. Remember to blot rather than rub; rubbing spills can actually force the liquid further into the fabric.

While you may not remove the entire spill on your initial attempt, a speedy response does make the cleaning process far less daunting.

Use Mild Soap and Water for Stains

For any stubborn stains that managed to manifest on your mattress, turn to our old, reliable friends: mild soap and water.

Mix mild laundry detergent with warm water. Then dip a soft, clean cloth into the solution, wring out excess water, and gently dab at the stain.

After applying this solution, make sure not to soak your mattress thoroughly. Just dampening the area with stains should suffice since too much wetness can lead to mold growth. Post-cleaning, ensure adequate ventilation for proper drying before making your bed again.

Avoid Bleach and Harsh Chemicals

It’s natural to want your mattress spotless, especially when you’re dealing with stubborn stains. It’s important to note that using bleach or harsh chemicals on your Siena mattress is a big no-no.

Strong cleaning agents such as these may leave a damaging residue within the fibers and ruin your mattress’s comfort and durability.

They could also potentially be harmful to your health, causing skin irritation or respiratory issues with prolonged exposure. Therefore, it’s best to stick to mild soap and water for any needed stain removal.

Rotate Mattress Every 3 Months

While this might not seem like an obvious step in maintaining the cleanliness of your Siena mattress, regular rotation does play a crucial role in preservation.

The rule of thumb is to rotate your mattress once every 3 months. Doing so can help even out wear and tear across the surface of the mattress, reducing sagging areas that might potentially collect dust or allergens.

Remember that this refers to rotating end-to-end (head-foot), not flipping over, which could damage its structure.

Ensure Adequate Air Circulation

Another important factor in maintaining both the cleanliness and overall health of your Siena Mattress is ensuring proper air circulation around it.

Make sure that your bed isn’t flush against a wall or tucked tightly between tight-fitting furniture, which can limit airflow, leading to dampness, mildew, or mold growth over some time.

Try keeping some space around all sides of your bed and occasionally prop up your mattress against the wall, or use a standing fan to aid ventilation.

Use a Quality Mattress Protector

You can combat the most common causes of mattress damage head-on simply by investing in a good-quality mattress protector.

This low-maintenance layer acts as a barrier between potential spills, stains, dust mites, and allergens. We are providing comprehensive protection to your mattress.

With this in place, most everyday dirt and stains will never reach your mattress surface, making cleaning considerably less daunting.

Most mattress protectors are machine-washable, making it easy for you to maintain cleanliness consistently.

Avoid Wetting the Mattress Excessively

While cleaning, it’s important to remember that excess water can be detrimental to your Siena mattress. Soaking a mattress might seem like the best way to tackle a deep-set stain.

But it can damage the inner layers of your mattress. It also paves the way for mold growth and persistent unpleasant odors.

Always clean using minimum moisture and focus mainly on the stained or dirty area rather than excessively wetting the entire surface.

Opt for damp cleaning methods instead of soaking methods, and consider using a spray bottle to control the amount of liquid being applied.

Dry Completely Before Reusing

Patience is crucial when it comes to mattress care! After caring for unwanted spills or stains, make sure your mattress is completely dry before you put the sheets back on or sleep on it again.

Using a wet or even damp mattress can lead to discomfort while sleeping, as well as potential health issues like mold growth.

You can expedite the drying process through simple measures like turning on a fan, opening windows for natural airflow, or using a hair dryer in a cool setting.

Although these might seem like time-consuming processes, they are absolutely worth the effort in maintaining your Siena mattress’ longevity.

Seek Professional Cleaning for Deep Stains

Despite all preventive measures and immediate care actions, some stubborn stains refuse to go away! In such cases, don’t hesitate to seek professional help.

A professional cleaning service will have specialized products and equipment explicitly designed for deep cleaning mattresses without causing damage.
