Full Mattresses

Wider than a Twin, smaller than a Queen, our Full-size mattress line-up delivers the trusted comfort that's legendary to Serta.

Why You Should Choose a Full size mattress

Full size mattresses are known as the next step after graduating from a twin, especially when it comes to our younger generation but that is not the only scenario full sizes are good for. If you live in a smaller space, this mattress size is a practical choice. Basically, a full size bed is great for a larger dorm room, a first apartment, a single sleeper who wants a little more room than a twin provides, couples who don’t mind cuddling, growing kids/young adults or even a guest room. With budget-friendly hybrid, gel foam, and memory foam options available, Serta has a full size bed for you.


If you are still debating if a full size is the way to go, read some of our frequently asked questions below.


What are Full size mattress dimensions?

Approx. Size: 53” X 74.5” / 3,948.5 sq in / 27.4 sq ft

Full sizes are 53 inches wide by 74.5 inches long approximately, give or take a little bit, which equates to 3,948.5 square inches and 27.4 square feet.


Queen vs Full sizes. What’s the difference?

A full is approximately 7 inches less in the width and approximately 5 inches less in length when you compare it to a Queen.


Is a double bed the same as a full?

Yes. Double and full are just two different names for the exact same size bed.


Can a full size bed fit two adults?

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 the mattress itself.


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 mattress online simple and easy with a 120-Day in-home trial along with free shipping right to your door.

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 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.
