Care & Use

Washing the Cover:

  • Washing the outer cover before first use is optional.
  • Cover zips off and goes right in the washing machine.
  • Be sure to leave the cover zipped for best results.
  • Wash on cold with a mild detergent.
  • Dry immediately in dryer on tumble dry low heat setting, allowing to dry thoroughly. DO NOT leave damp from wash; DO NOT hang dry.
  • Wash the cover as often as you like.

TIP: The Essential cover is made with a Viscose layer which may develop an odor if allowed to remain damp (like a wool sweater). To refresh, add 1/2 cup baking soda to the wash.

Washing the core:

  • For the really big mess or just for seasonal cleaning, the core can be washed whenever needed.
  • Wash in the shower with soap & cool water or rinse outside with a hose.
  • Shake excess water out of core and stand-up to dry.
  • Place in well ventilated area for faster drying.
  • Avoid drying in direct sunlight and do not use heating elements to speed the drying process.

Top 3 Mini Crib Mattress Questions

While the Newton Crib Mattress is not organic, it is a safer crib mattress for baby. Most "organic" baby crib mattresses feature only one organic component, such as cotton fabric or stuffing, but they aren't fully organic. Newton offers a mattress that is not only completely breathable to reduce suffocation risk but also offers the only washable crib mattress, making it the most hygienic sleep surface for your baby. Our products are GREENGUARD Gold Certified, proving that Newton offers only safe products for your family.

A breathable, washable crib mattress not only helps to reduce the risk of suffocation but also helps regulate the baby's body temperature (that's right, no more sweaty backs!) and reduces dust mites and allergens. This allows babies to sleep more comfortably and longer through the night.

Standard crib mattress sizes are regulated to meet a minimum sizing of 27 1/4" x 51 5/8" and not thicker than 6 inches. Standard crib sizes, while also regulated, can vary a bit based on construction. If a crib is labeled as a standard crib, Newton Crib Mattresses will fit nice and snugly inside.
