Shop our mattressesIs a full size mattress right for me?
Full size mattresses are a versatile option for college students, guest rooms, or families with smaller living spaces.
Compact enough for any space
Do you live in a small apartment? Are you sending your child off to college? A full mattress is larger than a twin but still large enough to offer you plenty of personal space.
Ideal for guest rooms
If a friend or a family member needs a place to crash, a full-size mattress in your guest room will make you an unforgettable host.
Just right for kids
A full size mattress fits almost anywhere, including bunk beds, trundle beds, or in a shared room.
How much does a high-quality full size mattress cost?
A reasonable budget with rational expectations ensures a smoother buying experience. Many full size mattresses come with a $4,000 price tag and are marketed as “luxury,” but the truth is, these marketing tactics make some mattresses appear more high-quality than they are.
In contrast, other mattresses may have a lower price tag and seem like a great budget option, when they’ll only last a few years before breaking down.
A high-quality, full size mattress usually costs under $2,500 but may go up slightly in price depending on special features or technologies.


- Cooling technologies, such as gel memory foam, copper-infused foam, advanced open-cell foams, plant-based foam, or precision cut-channels and zoned support.
- Added edge support (either in the form of quilted pillow topstitching or poly-foam reinforcing the edges)
- A longer than average warranty (the mattress industry standard is a 10-year warranty)
- White glove delivery if included with purchase
- Brand name and reputation
- Amount and/or quality of materials (for example, softer beds use more layers of foam so they tend to cost more; hybrids cost more because they use a combination of coils and foam; natural latex mattresses cost more because of their sustainability and durability)
- All-natural materials, such as organic cotton, natural latex, or CertiPUR-US® certified foam, Greenguard Gold Certified foam, and so on
Common mattress features increasing mattress cost
- Cooling features like plant-based foam, gel foam, or copper-infused foam

Is it possible to find high-quality beds in a box for a good price?
Mattresses available bed in a box style have risen in popularity, thanks in part to memory foam’s easy compressibility. Online mattress companies can sell high-quality mattresses for a lower price because they cut out the middlemen of traditional retail stores.

How are Amerisleep mattresses different from traditional foam beds?
Memory foam rose in popularity because of its ability to alleviate pressure. As you lie down on it, it softens and conforms to your body for the ultimate comfort experience. Because it can conform so closely, it also traps heat. Amerisleep solves this problem by using plant-based Bio-Pur® foam.
All Amerisleep mattresses are made in the USA and the foams are CertiPUR-US® certified.

Frequently Asked Questions
Are a full and a queen size mattress the same size?
A full size mattress is sometimes called a “double bed.” Fulls are bigger than twins—about 15 inches wider—but queen size mattresses are bigger than fulls, measuring about 60 inches by 80 inches. A queen size mattress can accommodate more sleepers, making it a better option for couples compared to a full size mattress.
What is the best full size mattress?
The best full size mattress should evenly support the body, while relieving pressure points for a better night’s sleep. However, there is no one “best” mattress, as everybody has different sleep needs. When searching for a new bed, consider your preferred sleep style, level of firmness, and recurring aches and pains, as these considerations should point you towards a comfortable bed for your needs.
What are the dimensions of a full size mattress?
A typical full size mattress is 53” by 75”. Many are under the assumption that since a full size mattress is also known as a “double bed,” a full is the equivalent of two twin mattresses side by side, but this is not true.
Who sleeps best on a full size mattress?
Full size mattresses are great options for teenagers, college students, and single adults with limited living space. They’re also the perfect choice for combination sleepers, who regularly toss and turn at night.
How do I choose a comfortable mattress firmness?
The right firmness should be based on your favorite sleeping position and body weight. For instance, plus-size back sleepers need a firmer surface to keep the spine in alignment without deep sinkage.
Sleeping Positions
- Side Sleepers
Side sleepers need a soft to medium feel for pressure relief in the shoulders and hips, filling in large gaps between the body and mattress.
- Back Sleepers
Back sleepers need a medium to firm mattress for enhanced lumbar support and to cradle the hips.
- Stomach Sleepers
Stomach sleepers need a medium-firm to firm surface to keep the body resting on top of the bed and prevent heavy sinkage.
- Combination Sleepers
Combination sleepers need a medium to medium-firm mattress to maintain alignment.
Body Weights
- Light
Light sleepers weigh less than 130 pounds and need a softer mattress to enable body-contouring on the surface for pressure point relief.
- Average
Average sleepers weigh between 130 pounds to 230 pounds and need a medium surface for an even balance of comfort and support.
- Plus-size
Plus-size sleepers weigh more than 230 pounds and need a firmer mattress to support the body without risk of sagging.
Our mattresses come in five different firmnesses:
- AS1—Firm
- AS2—Medium-firm
- AS3—Medium
- AS4—Medium-soft
- AS5—Soft
Mattresses can feel different over time because materials soften as they wear out or grow firmer as your body compresses the comfort layer through frequent use. If you need to change the feel of your bed, consider adding a foam topper.
What does an Amerisleep full size mattress cost?
A full size Amerisleep mattress ranges in price depending on the model, but pricing starts at $849 for the AS1, our firmest model.

What does the Amerisleep mattress warranty cover?
Amerisleep offers a 20-year warranty, one of the best in the industry, covering sagging greater than 1.5” inches and defects which could damage the bed. Most mattress companies only cover sagging greater than 2 inches.
How often should you replace your Amerisleep mattress?
Amerisleep mattresses are designed to last longer than the typical 7 to 9 year time period. Durable, eco-friendly foams are engineered to handle wear and tear for longer. Plus, each of Amerisleep’s mattresses are covered by a 20-year warranty.
Does an Amerisleep mattress reduce back pain?
Yes, the Amerisleep AS2 is one of the best mattresses for back pain, with responsive Bio-Pur® foam cradling the hips and HIVE® technology providing extra back support.
