Why Choose a Full Size Memory Foam Mattress?
Memory foam is known for its unrivaled pressure relief and a cloud-like feel. It conforms to your body's unique shape, cradling your curves and distributing weight evenly to minimize pressure points. Amerisleep's proprietary Bio-Pur® takes those qualities a step further by being more responsive and breathable than traditional memory foam. In a Full size—also known as a “double” bed—you get the personalized comfort of memory foam in a package that's perfect for single adults, teenagers, or guest rooms.
Our Full size memory foam mattresses are designed to provide:
- Ample Space for Solo Sleepers: Enjoy more room to stretch out compared to a Twin.
- Exceptional Pressure Relief: Soothe your joints and muscles with foam that adapts to your body.
- Superior Spinal Alignment: Promote a healthy sleep posture and reduce back pain.
- Minimal Motion Transfer: Enjoy undisturbed sleep, even if you toss and turn.
- Cooler Sleep: Our open-cell, plant-based Bio-Pur® foam helps you sleep cooler than traditional memory foam.
- Ideal for Smaller Bedrooms: The Full size offers a great balance between comfort and space-saving design.
If you're a solo sleeper looking for an upgrade from a Twin or need a comfortable mattress for a guest room, our Full size memory foam collection is the perfect solution.

Why Memory Foam? The Benefits Explained
Memory foam's greatest strength lies in its ability to conform to your unique shape. This adaptive quality cradles your body, easing tension and distributing weight evenly, particularly around sensitive areas like your shoulders, hips, and back. This targeted pressure relief is a key reason why so many people find memory foam mattresses incredibly comfortable. In a Full size, you get the personalized comfort of memory foam in a package that's perfect for solo sleepers.
Low Motion Transfer: Even if you're a solo sleeper, you'll appreciate memory foam's ability to isolate motion. Unlike traditional innerspring mattresses, memory foam absorbs movement, preventing it from rippling across the bed. This is beneficial for restless sleepers who toss and turn. A Full size provides ample space for you to move freely without being disturbed by your own motion.
What Makes Our Memory Foam Different
- Promotes Deeper Sleep: Our breathable materials create a cooler surface so you can fall asleep faster and stay asleep longer.
- Delivers Targeted Support: HIVE® technology and pocketed coils offer dynamic support, healthy spinal alignment, and unique pressure relief.
- Provides Responsive Comfort: Bio-Pur® is more responsive and breathable than traditional memory foam so it contours and cools.

Choosing the Right Size: Is a Full Mattress Right for You?
Our Full size mattresses, also known as “double” beds, measure 54 inches wide by 75 inches long. They are a great choice for single sleepers who want more space than a Twin, or for those with smaller bedrooms where a Queen might not fit comfortably. Full size mattresses are also a popular choice for guest rooms and teenagers’ rooms. To determine if a Full size is right for your bedroom, consider the size of your room and your personal sleep preferences.

Frequently Asked Questions
Are memory foam mattresses hot to sleep on?
Traditional memory foam can trap heat, but Amerisleep’s Bio-Pur® foam is open-cell and more breathable, reducing heat retention.
How long do memory foam mattresses last?
High-quality foam like ours often lasts 8–10+ years, thanks to robust density and supportive base layers. We back our mattresses with a 20-year warranty.
Which memory foam firmness is right for me?
It depends on your sleep position. Side sleepers often like medium to plush (AS3, AS4, AS5). Back sleepers may prefer medium-firm (AS2). Stomach sleepers might opt for AS1. Take our mattress quiz to find your perfect match!
Do memory foam mattresses smell (off-gassing)?
Our foams are low VOC and CertiPUR-US® certified. Any “new mattress smell” typically dissipates within days, if at all.
Can I use a regular box spring with a memory foam mattress?
A solid foundation or slatted base is usually recommended. A worn or old box spring might cause sagging. Learn more about whether a bad box spring can ruin a mattress.
How does memory foam help with back pain?
It cradles the spine, relieving pressure in the lumbar area, promoting better alignment—especially with zoned support (HIVE®).
Do I need a mattress protector?
While not mandatory, a protector helps keep the mattress clean and prolongs its lifespan.
Are your memory foam mattresses adjustable-base friendly?
Yes. All our foam models bend easily with adjustable bases—no damage, no compromise on support.
What should I do with my old mattress?
Many charities accept mattress donations. You can also check with your local waste management company for recycling options. We also offer old mattress removal services in select locations. Learn more about mattress donation options.
Do you have any showrooms where I can try out the mattresses?
Yes, we have a showroom located in Scottsdale, Arizona at the Optima Camelview. We encourage you to visit us and experience the comfort of our mattresses in person. Our knowledgeable sleep experts can answer any questions you have and help you find the perfect mattress for your needs.
What size sheets do I need for a Full mattress?
You will need Full size sheets for a Full mattress. Full sheets typically measure 54 inches wide by 75 inches long.
Is a Full mattress big enough for two people?
While a Full size mattress can technically accommodate two people, it is generally considered more comfortable for a single sleeper. For couples, a Queen or King size is usually recommended.
How much does a Full size memory foam mattress weigh?
The weight of a Full size memory foam mattress can vary depending on the specific model and materials used. On average, a Full size memory foam mattress from Amerisleep weighs between 50 and 80 pounds.
How does a Full mattress compare to a Queen size?
A Full mattress is 6 inches narrower and 5 inches shorter than a Queen size mattress. A Full is better suited for single sleepers or smaller bedrooms, while a Queen offers more space and is better for couples.
