FAQ

Kids' Twin Mattress

Will the Kids' Twin Mattress fit my bed frame?

The mattress is designed to fit all traditional twin bed frames. It measures 38” x 75” x 5.5” ( LxWxH).

Are there flame retardants?

While many of our competitors use toxic chemical fire retardants, we do not. Instead, we use a layer of viscose material sewn into our cover. Viscose material is made from reconstituted wood pulp. We quilt this material into our mattress covers for a safer, non-toxic solution.

Is the mattress comfortable for my child?

Our Kids' Twin Mattress is made with the same technology and comfort that Newton is known for in our crib mattresses. Many parents tell us their little ones start sleeping better from the first night, and we couldn’t be happier. Try it yourself risk-free with our 100-night trial.

Can I lay on this with my child?

We know how bedtime can be during the toddler and preschool years (“Just one more book?”). That said, this mattress is specifically designed for kids up to 100lbs. We don’t recommend that adults sleep on the mattress as it could impact the integrity of our patented Wovenaire® core. So snuggling together on the kids' mattress for one more book at bedtime is fine; however, sleeping for a longer duration on it is not recommended for parents.

Waterproof Organic Twin Mattress Pad

Does the pad offer cushion/comfort/padding?

It sure does! In addition to a completely waterproof lining, our mattress pad features an organic cotton surface and a comfy cushion to provide additional padding for your big kid.

Can I use a sheet?

We recommend using a cotton sheet for the most comfortable and breathable sleep for your child.
