CertiPUR-US® Certified means our foam was tested for and is free from harmful chemicals and gasses

To protect your mattress from stains and spills, we highly recommend using a mattress protector; This will also help with the overall health and lifespan of your mattress.

We do not recommend applying liquids to the product; Applying liquids may stain the fabric and make the soiled area worse; Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product.

We suggest applying baking soda to the soiled area, let stand about 15 minutes, vacuum, and repeat as needed; Air the product out as much as possible.

Serta iSeries NXG mattresses are compatible with most frames, including: traditional frames, box springs, platform frames, slatted frames, bunky boards, and adjustable frames.
