Can I remove my mattress cover?
We recommend that you do not remove the mattress cover. If you need to remove the cover for any reason, we recommend that you do not touch or place anything on the fire retardant sock. The Lull Mattress fire retardant sock contains small amounts of fiberglass, which makes the mattress fire retardant (the fiberglass allows us to sell a safe mattress without using harmful chemicals). The small amounts of fiberglass will not affect human health while sleeping, but you should not touch or place fabrics directly on the fire retardant sock.
