Yes, especially for those adults who like to cuddle. However, some couples may prefer more room and that is where a Queen or King would be best.

How much does a Full sized mattress cost?

A quality full size bed on average can range anywhere from $600 to $2,000. It all depends on the materials used to make it.

Why should I buy a Serta mattress full size online?

While the Serta brand is in a lot of stores, we have made shopping for a Full-size online simple and easy with a 120-Day in-home trial along with free shipping right to your door.

Do you ship internationally?

We only ship within the lower 48 states of the United States. Unfortunately, right now 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.
