Do Lull Mattresses Contain Fiberglass?

No, all Lull mattresses currently produced and sold are fiberglass-free. Some older Lull models contained glass fibers as part of their fire retardant barrier, but their current lineup is entirely fiberglass-free.

While Lull has never publicly disclosed exactly what date they became fiberglass-free, it appears that the transition happened around 2022-2023.
