Tulo might not be among the top brands in the mattress industry, but it still is one of the most popular brands (check the top rated mattresses). It is a sub-brand by Mattress firm and is relatively new. However, the reason for that is affordability and overall good for all sleep positions.
But do Tulo mattresses have fiberglass in them? We are about to learn all about them, so keep reading.
Tulo's mattress cover is made of natural materials extracted from bamboo-based rayon. So, the cover doesn't contain fiberglass. However, the same can't be said for their polyurethane foam support layer.
Not much information is available on whether Tulo mattresses contain fiberglass. This is because their website or any other source doesn't have such information.
This can be because they are new to the market and have yet to include this information on the website. Otherwise, their mattresses contain fiberglass; they don't want to share it with their customers. But one thing's for sure; they don't want you to remove their mattress cover. So, this could be an indication that they might use fiberglass in their memory foam bamboo mattress.
Is Fiberglass Present in Tulo Mattress?
Despite being CertiPUR-US certified, there is no information on their website about whether their mattress contains fiberglass. There is no information about any complaints from the customers as well.

So, there is a bit of uncertainty about whether Tulo mattresses have fiberglass in them or not. The fact that their website doesn't mention anything about it might be due to two reasons.
One is maybe they didn't update their website about it, or they might not want to mention it. The second reason could indicate that their mattresses have fiberglass in them, and Tulo might not want to disclose it.
Why Saatva Mattress is better instead of Tulo Mattress?
The primary reason we recommend Saatva over Tulo is that Saatva is one of the top brands on the market (check the most comfy mattresses). It has been around for many years, and the company is transparent about its business.
It's a sure-shot fact that Saatva mattresses don't have fiberglass. Instead, these mattresses are made of quality materials that are naturally sourced, and the mattresses are handcrafted.
However, Tulo is a relatively new brand, and there is not much information available on the internet about their mattresses. Upon digging for more information, you will notice that there are no complaints as well.
Their website has yet to provide information on whether their mattresses contain fiberglass. So, Saatava is a better choice here.
Why Does Tulo Use Fiberglass?
Of course, not much evidence supports the claim that their mattresses have fiberglass. But there is no evidence available to oppose it as well.
However, mattress manufacturers use fiberglass because it is mandatory under federal law. The law directs mattress companies to make their mattresses fire retardant. Therefore, the cheapest available option on the market is fiberglass.
Still, better and healthier options, such as organic wool, latex, or natural thistles, are available. Sourcing these materials is expensive, and this additional cost adds to the mattress price. Tulo mattresses are not costly, so maybe they have fiberglass.
What Fire Retardant Does Saatva Use?
On the other hand, Saatva is an entirely different story. They have been around for so many years and are very transparent about how they conduct their business.
Saatva mattresses don't have fiberglass in them because they are CertiPUR-US certified. Apart from that, the materials used in developing their mattresses are all natural (check the best selling organic mattresses).
These premium handcrafted mattresses come with natural titles and organic New Zealand wool. So, these are the materials Saatva uses as fire retardants in their mattresses.
How to Check If A Tulo Mattress Has Fiberglass?
As there is not much information available about whether Tulo mattresses have fiberglass in them, your best shot is to find out about it on your own.
There are a few ways to determine whether your mattress has fiberglass. One way to find out about it is to check the label of your mattress.
This label has a list of materials in the construction of the mattress. If it mentions anything associated with fiberglass, it will finally have fiberglass.
Also, you can check the cover of your mattress and see if it is removable. If the mattress is removable, then everything is fine. But if it's not, the manufacturer tells you not to remove the cover. In other words, the mattress does not contain fiberglass.
Do Tulo Memory Foam Mattresses Have Formaldehyde?
Tulo's lavender-infused memory foam mattress and Tulo hybrid mattress come with CertiPUR-US certification, indicating that their mattresses don't have formaldehyde or other VOCs.
Their website might not provide any authentic information on fiberglass. But it does mention that their mattresses don't have these harmful chemicals.
What Mattress Brands Have No Fiberglass?
There is a lot of uncertainty around Tulo, as you are unsure whether their mattresses have fiberglass.

Therefore, we recommend using Saatva because their mattresses don't contain any VOCs, harmful chemicals, or fiberglass (check the best selling fiberglass-free mattresses). These mattresses feature quality materials that come from sustainable sources.
Reddit Reviews on Tulo Mattresses
User 1
I found the Tulo mattress to be an overall good mattress. It does offer plenty of edge support and responsiveness. My husband and I enjoy sleeping on it.
We are not sure whether it contains fiberglass. And there isn't much information available about it either. We tried to contact Mattress Firm about it, but we didn't get any satisfactory answer.

How to Choose the Right Mattress
With thousands of mattress options available, cutting through the noise requires focusing on what actually matters for your sleep quality and budget.
The Three Things That Matter Most
- Support and alignment. Your mattress should keep your spine in a neutral position regardless of sleep position. If you wake up with aches or stiffness, your mattress is failing at its primary job.
- Temperature regulation. Sleeping hot disrupts deep sleep cycles. Innerspring and hybrid mattresses with coil systems promote airflow far better than all-foam designs.
- Purchase protection. A generous trial period (100+ nights), strong warranty, and hassle-free returns protect you from an expensive mistake. Never buy a mattress you cannot return.
A Strong Benchmark
The Saatva Classic ($1,779 Queen) scores well on all three factors: coil-on-coil construction for support and airflow, a 365-night home trial for risk-free evaluation, and a lifetime warranty for long-term protection. Free white-glove delivery and old mattress removal are included with every order.
