Serta iSeries NXG Collection

What does “NXG” mean?

NXG stands for Next Generation. It represents the evolution of the iSeries line — upgraded with higher-density foams, improved cooling technology, and refined feels across every comfort level.

What firmness options are available?

You can choose from plush, medium, or firm models to match your preferred comfort and support level.

What’s the difference between the iSeries NXG Hybrid and All-Foam models?

Hybrid models combine memory foam with an advanced coil system for a slightly more responsive, supportive feel and better airflow.

All-Foam models offer a smoother, more body-hugging feel that absorbs more motion and contours closely to your shape.

Is iSeries NXG compatible with adjustable bases?

Yes, every iSeries NXG model works seamlessly with Baselogic® adjustable bases for customizable comfort and support.

Can I expedite my order?

We do not have an expedited delivery option at this time. Our site will provide the best delivery estimate at checkout.

Do you ship internationally?

Directly on our website, we only ship within the United States, to the lower 48 states. At this time we do not offer shipping to Alaska or Hawaii.

Do you offer financing?

Financing is available directly through our website. We have partnered with Affirm to offer financing or pay-over-time options for our customers. At checkout, you will be given the option to pay through Affirm. If approved, you will be given loan options for 3, 6, or 12 months. All interest is provided up front, there are no hidden fees, and only a soft credit check is done through Affirm's system for approval. After you've confirmed your choice, you will be redirected back to our website to complete checkout.

Affirm only requests a soft credit check for approval, so the credit inquiry won’t affect your credit score. Once you've selected your financing term, you will be redirected back to the website to complete your purchase.

For returns and cancellations, refunds will be processed through Affirm and posted to your Affirm account. Refunds will be processed within 3-10 business days. Keep in mind the interest charge will not be refunded.

Please note that financing through Affirm is not available in West Virginia and Iowa.

What is the difference between ordering online from Serta.com and another retailer?

When you place an order through Serta.com, you are backed by the 120-Day In-Home Trial. We know ordering a mattress online can be intimidating, so we want to take the risk out of it for you with the in-home trial that allows the perfect amount of time to test the mattress and accessories in your home and make sure it's right for you. If you decide it is not the right fit, we make returns easy and free.

Serta products are sold at many different retailers through the United States. Our goal is to be able to serve our sleepers where they feel the most confident purchasing their Serta products. Many retailers will have products on display for sleepers to test out before making your decision, and may offer different pricing or promotional advantages for buying directly through a retailer. Retailers may also have different models than what you see directly on the website.

Regardless of where you purchase, you can be confident you are getting a quality Serta product.

Do you make custom sizes?

We are unable to provide custom sizes at this time. For now, we carry industry standard sizes of twin, twin XL, full, queen, king, and California king.
