Nectar says every mattress in its current US lineup is 100% fiberglass-free. That answer applies to the exact models on Nectar's US product pages reviewed in July 2026. It should not be projected backward onto an older Nectar mattress, a different national market, or stock held by another retailer.
Older Nectar mattresses require a model-specific check. Public settlement materials list certain Nectar product names and SKUs, while the settlement class is limited to units sold in an earlier period that contained fiberglass in an inner fire-retardant sock. Some of those names resemble products sold today, which is why the name "Nectar Premier" or "Nectar Hybrid" cannot answer the question by itself 1 2.
What Nectar says about its current mattresses
These are the fiberglass statements on Nectar's current US product pages:
| Current model | Nectar's statement |
|---|---|
| Nectar Classic Memory Foam | "100% fiberglass-free" 3 |
| Nectar Premier Memory Foam | "100% fiberglass-free" 4 |
| Nectar Luxe Memory Foam | "100% fiberglass-free" 5 |
| Nectar Ultra Memory Foam | "100% fiberglass-free" 6 |
| Nectar Classic Hybrid | "100% fiberglass-free" 7 |
| Nectar Premier Hybrid | "100% fiberglass-free" 8 |
| Nectar Luxe Hybrid | "100% fiberglass-free" 9 |
| Nectar Ultra Hybrid | "100% fiberglass-free" 10 |
| Nectar Kids Memory Foam | "100% fiberglass-free construction" 11 |
This is positive, model-specific manufacturer information. It is stronger than simply noticing that fiberglass is absent from a marketing material list. It is not the same as an independent teardown or laboratory analysis, so we describe it as Nectar's claim.
Nectar also says its modern adult mattresses use rayon, or a rayon and polyester blend, for the flame-retardant layer instead of fiberglass 12. That statement concerns modern Nectar construction. It does not establish the barrier material in an older unit.
Why an older Nectar may have a different answer
Mattress designs change while product names are reused. The cover, fire barrier, foam arrangement, manufacturer, and prototype can change without leaving an obvious difference in a retailer's abbreviated product title.
Court-authorized materials for a proposed 2026 class-action settlement define an affected mattress as one sold to a US consumer from October 1, 2017, through June 30, 2024, that contained fiberglass as a fire-retardant material in its inner sock. The defendants deny the legal allegations and wrongdoing, and the court had not decided the merits when the notice was issued 1.
The settlement administrator's affected-product list names these Nectar products, with associated SKUs in the source:
- The Nectar Mattress
- The Nectar Memory Foam Mattress
- The Nectar Premier Mattress
- Nectar Premier Memory Foam Mattress
- The Nectar Premier Mattress with NectarCool Technology
- The Nectar Copper Mattress with NectarCool Technology
- Nectar Hybrid Mattress
- Nectar Premier Hybrid Mattress
- The Nectar Lush Mattress
The list was updated in May 2026 2. A matching name is a reason to compare the SKU, labels, purchase record, and dates. It is not a reason to assume that every mattress ever sold under that name has the same construction.
Public consumer reports need the same restraint. One report in the Consumer Product Safety Commission's SaferProducts database describes a queen Nectar mattress manufactured on February 25, 2020, with model 410321-11x and prototype NNQ11. The consumer alleged that fiberglass escaped after the cover was removed 13. The database identifies this as a consumer report, not a CPSC laboratory finding or a recall. It is evidence about that reported event and those identifiers, not proof about the whole brand.
What fiberglass does in a mattress
Fiberglass consists of thin glass fibers. In some mattresses, glass fibers are woven into a fabric or incorporated into an inner sock around the foam. The sock is intended to slow fire spread and help the finished mattress pass flammability tests 14.
US law does not require manufacturers to use fiberglass. Mattresses are subject to cigarette-ignition requirements under 16 CFR Part 1632 and open-flame performance limits under Part 1633 15. The CPSC describes the open-flame rule as performance-based and says it does not tell manufacturers how to design a mattress to pass 16. Manufacturers can choose among compliant barrier systems.
Fiberglass is mainly a concern when fibers leave the mattress. Contact can irritate the skin and eyes. Small airborne pieces can irritate the nose, throat, and lungs and may cause breathing problems 14. These established irritation risks do not support claims that ordinary use of an intact mattress inevitably causes chronic lung disease or cancer.
How to check your exact Nectar mattress
Do not unzip, cut, or open the mattress to investigate. Use the outside labels and records instead.
1. Photograph every sewn-in label
Capture the entire label in good light. Look for:
- exact model or item name
- SKU, item number, or serial number
- model identification
- prototype identification
- mattress size
- manufacturer or importer
- month and year of manufacture
- any separate materials or care label
Federal Part 1633 labels identify the manufacturer or importer, month and year of manufacture, model, and prototype, among other compliance information 15. These fields help separate one generation from another. They do not necessarily disclose every fire-barrier material.
2. Check the purchase record separately
The manufacture date describes when the unit was made. A receipt or order history describes when and where it was sold. Keep both because the proposed settlement's class period is based on purchase in the United States, not simply the date printed on the mattress 1.
3. Read material wording, but do not treat silence as proof
A label may use wording such as "fiberglass" or "glass fiber." The California Department of Public Health warns that some mattress labels do not list fiberglass even when it is present 14. Therefore:
- a positive glass-fiber listing is useful evidence
- no glass-fiber listing is not conclusive evidence of absence
- a generic foam or cover description does not disclose the inner sock
- material lists copied from a retailer are not a substitute for the exact mattress labels
A CertiPUR-US logo also does not answer the question. CertiPUR-US certifies flexible polyurethane foam, not the complete mattress. The organization says certified foam does not use fiberglass, while a mattress cover or barrier sock may still contain it 17.
4. Match the identifiers, not just the product name
Compare the exact SKU or item number with the settlement administrator's affected-product list. Then compare the model and manufacture date with any applicable recall or manufacturer record. If the identifiers do not match cleanly, leave the composition unresolved rather than guessing.
5. Ask Nectar for written, model-specific confirmation
Send a photo of the labels and ask:
Does this exact mattress, identified by model, prototype, SKU, size, US market, and manufacture date, contain fiberglass, glass fiber, glass wool, or glass-reinforced fabric in the cover, inner sock, fire barrier, or any other component? What is the fire-barrier composition, and is this exact cover designed for consumer removal?
Save the written response with the receipt and label photos. A general statement about mattresses Nectar sells now does not resolve the construction of a discontinued model.
Do not assume a zipper means the cover is removable
Nectar's current general FAQ tells owners not to remove the mattress cover and recommends spot cleaning with a damp cloth and mild detergent. It says removal can void the warranty and damage the underlying foam 18.
The current Nectar Kids mattress is a specific exception: its product page describes the cover as removable and machine-washable 11. Follow the care instructions for the exact model you own. For an older mattress with unclear instructions, leave the cover sealed until Nectar confirms in writing that consumer removal is intended.
A zipper alone proves nothing. CertiPUR-US notes that some zippers exist only for factory assembly and do not mean the consumer should remove the cover 17.
If fibers may already have escaped
Stop using and disturbing the mattress. Keep children, pets, and unnecessary foot traffic away from the area. Do not cut the mattress, open it further, sweep suspected fibers, or move it uncovered through the home.
Photograph the intact labels and visible damage without handling the exposed inner material. Contact Nectar with the model information and ask how it will handle the mattress. If fibers are widespread, consider a qualified environmental-cleanup professional rather than improvising removal. The California Department of Public Health advises reducing further spread, using HEPA-filtered cleanup rather than sweeping, and covering a contaminated mattress before removal 14.
Move away from the exposure area if your eyes, skin, nose, throat, or breathing become irritated. Seek medical care promptly for breathing difficulty or symptoms that are severe or do not settle.
Common questions
Was a Nectar mattress recalled because of fiberglass?
A 2022 CPSC recall covered about 700 Nectar Premier mattresses that failed the federal flammability standard. It was limited to king mattresses manufactured September 24, 2021, and queen mattresses manufactured September 27, 2021, with the specified model markings and prototype ECS2003RHCH 19.
The recall notice did not identify fiberglass as the cause or state what barrier material those units used. A flammability-test failure and a fiberglass finding are different claims.
Does a current fiberglass-free claim prove an older Nectar is fiberglass-free?
No. It proves what Nectar currently states about the exact product page. It does not establish the construction of an earlier generation, a mattress made for another market, or old inventory sold later by a third party.
Is a Nectar mattress safe if its cover stays intact?
For a current model, use the exact product claim and care instructions. For an older model with unresolved construction, keeping the cover sealed avoids creating the main release route described in public-health guidance and consumer reports 14. It does not identify what is inside.
Can shiny fibers confirm fiberglass?
Shiny fibers can raise suspicion, but appearance alone cannot identify their composition or source. Do not open the mattress for a closer look. Use the labels, model records, written manufacturer confirmation, and professional assessment if contamination is suspected.
