FAQ

What sizes does it come in? This listing is the California King size, W 83.5" × D 72" × H 8".

How should I set it up and what does the warranty say? Open the box and allow 48 hours for full expansion. The 10-year non-prorated warranty applies, and buying the mattress and foundation from two different brands may void it, so check the warranty for details.

Frequently Asked Questions

Everything you need to know before you order. Still stuck? Call or text 844-305-3247 or email support@newyorkmodern.com.

How long will it take to get this?

In-stock items ship within 1–3 business days. Transit time averages 5 to 14 business days depending on the size of your order and your destination. You will get a tracking number by email as soon as the order leaves our warehouse.

What does delivery include?

Free Threshold Delivery, included on orders of $50 or more, brings the piece to the first dry area of your home, such as inside the front door or the garage. It does not include unpacking or assembly, and the delivery team does not take packaging away. White Glove Delivery and Assembly is available at checkout for $199.99: delivery to the room of your choice, full assembly and removal of all packaging.

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?

You have 30 days from delivery to start a return. Contact us first for a Return Merchandise Authorization number. The piece must be new, unused and in its original packaging. Non-defective returns carry a 30% restocking fee, and return shipping is paid by the customer. Damage or defects reported within 24 hours of delivery are repaired or replaced at no cost.

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.
