Important Notice: Flammability Compliance
If you select a mattress cover option other than the Terry Velour cover, the product will not meet federal flammability standards required for items sold as “mattresses.” In this case, your order will be classified and shipped as a “Custom Sleep Product” rather than a “Mattress.”
At FoamOrder, we intentionally offer options with fewer chemical additives to support our commitment to natural and organic materials. Some options do not include the flame-retardant chemicals necessary to comply with federal flammability standards (16 CFR 1632 and 1633).
By purchasing without the Terry Velour cover, you acknowledge and agree that:
- The item is being sold to you as a “Custom Sleep Product,” not as a “Mattress.”
- With the selected cover, the product does not comply with federal flame-retardancy requirements.
- You accept full responsibility for the use of this product.
