  • Cooling quilted poly-blend cover: a quilted top surface designed to feel cool.
  • Shift-resistant lower comfort cover: helps keep the layers stable underneath you.

Can I return a mattress?

Mattresses are not returnable unless they are structurally defective. If yours arrives with a defect, send a photo to support@newyorkmodern.com within 24 hours of delivery and we will take care of it.

What if I change my mind?

What warranty comes with it?

Our products are covered by a limited manufacturer warranty against defects in materials and workmanship; the length of coverage depends on the product. We handle claims for you: a technician first attempts a repair, and a replacement is arranged if the item cannot be restored. It does not cover normal wear and tear, pet or accidental damage, or commercial use. Email us for a free copy of the warranty for this product. Orders placed with a promotional 5-year warranty keep those terms.

Can I pay monthly?

Yes. You can pay over time with Affirm or Klarna at checkout, subject to eligibility (see affirm.com/disclosures for lending terms). PayTomorrow is also available, including a no-credit-needed option. Prequalifying does not affect your credit score.
