The original Siena mattress, sold from its 2022 launch through mid-2024, contained a fiberglass fire barrier sewn into an inner sock under the cover. The redesigned Siena mattresses sold today are fiberglass-free. Banner Mattress walks through which version you might own, the recently approved $9 million class-action settlement that covers Siena buyers, and how to check the law tag for proof.
Quick answer
- Old Siena (2022 launch through June 30, 2024): contained fiberglass as the inner fire barrier.
- Current Siena Signature 10″ and 12″ (mid-2024 onward): fiberglass-free; uses a knit rayon-blend fire sock instead.
- Settlement: the Ashley Furniture and Resident Home class-action (preliminary approval March 19, 2026; claims due July 17, 2026) treats Siena as a covered brand and offers store-credit vouchers for purchases between October 1, 2017 and June 30, 2024.
Why the answer changed in 2024
Siena launched in 2022 under Resident Home, the same parent company behind Nectar, DreamCloud, and Awara. To meet the federal open-flame standard 16 CFR 1633 at a $499 queen price point, Siena's first generation used a woven fiberglass sock as the heat-shield layer under a removable zip cover.
That design is what triggered the lawsuits. Customers who unzipped the cover for cleaning - exactly what the zipper invites - exposed the fiberglass sock and shed glass fibers into bedrooms, HVAC ducts, and laundry.
In 2024, Resident Home pushed a redesign across the Siena, Nectar, and DreamCloud lines and switched to a fiberglass-free knit fire barrier. Ashley Home then completed its acquisition of Resident Home in early 2026, and the current Siena Signature page now states "fiberglass-free construction" outright.
How to tell which Siena you own
Read the white law tag stitched to the side of the mattress. It will list every fiber by percentage. Two patterns matter.
Old Siena (fiberglass): the tag will show "glass fiber" or a number followed by % glass. Often paired with rayon and polyester. Manufacture date will read 2022, 2023, or first half of 2024.
Current Siena (fiberglass-free): no glass fiber line. The barrier is listed as rayon, polyester, and a treated cellulose blend. Manufacture date is mid-2024 or later.
If the law tag has been removed or is unreadable, contact Siena support with the order number; the customer service team can pull the build sheet for that serial.
Construction of the current Siena Signature 10″
The redesigned 2024+ Siena Signature is an all-foam, four-layer build:
- Cover: stretchy polyester-blend knit with a fiberglass-free flame-resistant inner sock.
- Top comfort layer: gel-infused memory foam for pressure relief.
- Transition layer: 2″ convoluted (egg-crate) polyfoam for airflow and faster response.
- Support layer: 5″ high-density base foam for edge stability and load support.
Foams are CertiPUR-US certified, which independently confirms there are no PBDEs, formaldehyde, mercury, lead, or ozone depleters in the foam itself. CertiPUR-US does not certify the fire barrier, so it does not by itself rule out fiberglass - that's why the law tag check still matters.
The 2026 class-action settlement: what Siena owners get
The Ashley Furniture and Resident Home Mattress Settlement (case granted preliminary approval March 19, 2026, in the U.S. District Court for the Southern District of Ohio) created a $9 million voucher fund covering Ashley, Nectar, DreamCloud, and Siena mattresses purchased between October 1, 2017 and June 30, 2024.
- Voucher amount: the $9 million pool is split evenly across valid claims; per-claim value depends on total filings.
- Where it spends: Ashley Furniture, Nectar, DreamCloud, or Siena. Not redeemable for cash.
- Proof needed: brand, approximate purchase date, and place of purchase. Receipts help but are not strictly required.
- Deadline: claim form must be submitted by July 17, 2026. File at
mattressclassactionsettlement.com.
You do not need to have removed the cover or experienced visible fiberglass shedding to file - purchase during the class window is the qualifier.
What to do if you own an older Siena
The single rule that matters: do not unzip the cover. As long as the fiberglass sock stays intact under the outer fabric, federal flammability law treats the mattress as compliant and safe to sleep on.
If the cover is already off or damaged:
- Stop sleeping on it. Tape any tears with packing tape to limit further shedding.
- Wear long sleeves, an N95 respirator, and goggles before handling it.
- Bag the mattress in a heavy plastic mattress disposal bag and dispose through bulky-waste pickup; do not drag it through carpeted rooms.
- HEPA-vacuum the bedroom (no regular vacuum - it scatters fibers), launder bedding on hot, and run the HVAC through a fresh filter.
- File the settlement claim while the window is open.

Fiberglass-free Siena alternatives if you want a new bed today
If you prefer not to deal with a fiberglass-bearing model at all, three current options sit in the same budget tier and use natural or knit-fiber fire barriers verified on the law tag:
- Bear Original - uses a treated rayon barrier, GREENGUARD Gold certified.
- Avocado Eco Organic - GOTS-certified organic wool fire barrier, no synthetic flame retardants.
- Helix Sunset Luxe - fiberglass-free across the entire Helix line as of 2024, knit rayon barrier.
Siena's redesigned Signature 10″ and 12″ also belong on this list - the brand corrected the fire-barrier design before being acquired by Ashley Home and current units ship fiberglass-free.
Bottom line
Old Siena mattresses (2022 to mid-2024) contained fiberglass; current Siena mattresses do not. If you bought one within the class window, file the settlement claim by July 17, 2026 - it costs nothing and the voucher is worth more the fewer people file. If you're shopping today, the redesigned Siena Signature is fiberglass-free, but verifying any mattress on its law tag is still the only way to be certain.
Siena fiberglass FAQ
Does the current Siena mattress have fiberglass?
No. Siena Signature 10" and 12" units shipped from mid-2024 onward use a fiberglass-free knit rayon-blend fire barrier. The brand confirms fiberglass-free construction on its product pages, and the law tag will list rayon, polyester, and treated cellulose with no glass-fiber percentage.
Did older Siena mattresses contain fiberglass?
Yes. From the 2022 launch through June 30, 2024, Siena mattresses used a woven fiberglass sock as the inner fire barrier under a removable zip cover. That generation is the one named in the 2026 Ashley Furniture and Resident Home class-action settlement.
How do I check my Siena law tag?
Find the white sewn-in tag on the side of the mattress and read the fiber-content list. If you see "glass fiber" or a percentage of glass, your unit has the fiberglass barrier. If the list shows only rayon, polyester, and cellulose blends, your unit is the redesigned fiberglass-free model.
How much is the Siena settlement voucher worth?
The $9 million fund is split evenly across valid claims, so the per-claim value depends on how many people file. Vouchers redeem at Ashley Furniture, Nectar, DreamCloud, or Siena. Filing deadline is July 17, 2026 at mattressclassactionsettlement.com.
Is it safe to sleep on a Siena with fiberglass?
Yes, as long as the outer cover stays zipped and intact. Federal flammability law treats the mattress as compliant in normal use. Risk only appears if you unzip or tear the cover, which exposes the inner fiberglass sock and lets fibers shed into the room.
