What’s great about this product is you can choose your desired level of firmness, whether it’s plush, medium, or firm. It features a 2.5-inch layer of ventilated gel memory foam on top of a 7.5-inch layer of high-density support foam. The mattress is made from open-cell memory foam so it evenly conforms to your body shape, and it’s even ventilated for improved breathability.

Another great option for a memory foam twin mattress is the Zinus Memory Foam 12-Inch Green Tea Mattress. Not only is this mattress a great value, but its quality should assuage any worries about buying a mattress online.
This twin mattress is 12 inches thick and made up of several distinct layers. On top, there’s a 3-inch layer of memory foam to provide pressure-relieving support by contouring to your body. Underneath, there’s a 2-inch layer of “comfort foam” that provides extra cushion and dissipates heat, and finally, the base is made of two levels of high-density support foam. Overall, this mattress is medium-firm, which can reduce low-back pain.
The Zinus Memory Foam Mattress comes rolled up in a box, and it takes up to 72 hours to fully expand. The mattress comes with a 10-year limited warranty.
"Our 2-year-old son loves this mattress. He had been sleeping on a traditional spring mattress that was very firm and ended up crawling into bed with us for at least four nights a week. We attributed it to sleep regression, variations in his schedule, and his history as a difficult sleeper as a baby. But after switching to the Zinus, he was happy to go back to sleep in his own bed even when he did wake up in the middle of the night."—Katie Begley, Product Tester
Best for Kids: Casper Original Mattress
:max_bytes(150000):strip_icc()/CasperOriginalFoamMattress-ed2226a34c02455989ef085672c25661.jpg)

Offers three zones of targeted support
Breathable foam helps keep you cool
Pricier than other twin-sized mattresses
May be too soft for some
When it’s time to move your toddler into a “big kid” bed, you’ll likely need to buy them a twin mattress. Luckily, the Casper Original Mattress is an affordable option that's sized just right for kids.
Though some may be skeptical about a “Bed in a Box,” the Casper Original Twin delivers a comfortable and cool night’s sleep for both kids and teenagers. The Casper Original Twin measures 75 x 38 inches and it has multiple layers of high-tech memory foam that support and cradle the body. If you’re on the fence, this mattress is protected by a 10-year limited warranty plus a 100-night free trial. This product is well-made and comfortable, and you can use it as a daybed after your child has upgraded to a larger size.
"If staying cool helps your child sleep more soundly, the Casper mattress is an ally you can’t do without. The company uses open-cell foam in all of their mattresses in order to keep sleepers cool throughout the night."—Katie Begley, Product Tester
Best Memory Foam: Leesa Original Twin Mattress
:max_bytes(150000):strip_icc()/LeesaTwinMattress-d1c39a8d34d24b1991399475fcaa5908.jpg)
Materials: Memory foam | Thickness: 10" | Certifications: B-Corp | Return Policy: 100-night trial, 10-year warranty | Twin XL: No
Cooling top layer
Great for back and stomach sleepers
May be too firm for side sleepers
If you’re looking for a memory foam mattress that provides exceptional comfort and support, the Leesa Twin is a great option. It’s made from three layers of foam that are expertly balanced to provide a restful night's sleep. The 6-inch base of dense foam gives the mattress structure while 2 inches of memory foam contour to your body and relieve pressure. A layer of cooling foam is spread over the memory foam to increase airflow (memory foam is known to be quite hot). It measures 39 by 75 inches, and similar to the Casper Twin, it comes in a compressed package that will expand once it’s out of the box.
"The first time we laid on this mattress we could feel the mix of foam layers at work as our body didn’t immediately sink in. Rather, it offered a gentle cushion with firm support underneath. The foam doesn’t conform to your body right away, which makes this mattress feel firmer at first. In fact, it definitely felt firmer than expected for a mattress that’s rated a 5 on a 1 to 10 firmness scale."—Stacey L. Nash, Product Tester
Best for Bunk Beds: Zinus 6-Inch Foam and Spring Twin Mattress Set

Bunk beds are a popular solution when your kids share a room, but it can be tricky to find mattresses for them. First of all, you need two mattresses, and second, the mattresses must be low-profile. Luckily, the Zinus 6-Inch Spring Twin Mattress Set is a budget-friendly solution for those with bunk beds, as it provides two mattresses for the price of one.
This product comes with two 6-inch mattresses made with supportive Bonnell innerspring coils and CertiPUR-US certified foam. Each mattress also has a quilted tight top cover.

Featuring breathable construction to keep you comfy, the classic innerspring mattress offers medium firmness, edge support, and a tight-top memory foam mattress topper for added comfort and support. As an added bonus, the mattress uses pocketed coils to minimize motion transfer.
"The most commented-on detail from our guests is how well they sleep on our mattresses. This is the foundation for the appeal of our whole bedding package.

Best Topper: Linenspa 2-Inch Gel Infused Memory Foam Mattress Topper
:max_bytes(150000):strip_icc()/LinenspaMattressTopper-becabf18f61f44afae402b9d8e53a0c1.jpg)

An affordable way to make your mattress more comfortable
Gel-infused memory foam helps keep you cool
May need to air out after opening
If you already have a twin mattress but it’s not as comfortable as you would like, you might consider purchasing a product like the Linenspa 2-Inch Gel Infused Memory Foam Mattress Topper instead of a whole new mattress.
This mattress topper can be used to revitalize your existing mattress. It’s made of a 2-inch layer of memory foam that will provide added comfort and support during the night, and it’s infused with temperature-regulating gel that will keep you from getting too hot—a common complaint about memory foam mattresses. The topper is backed by a three-year warranty, and it’s the perfect way to make a cheap twin mattress more comfortable.
The Lucid 10-Inch Gel Memory Foam Mattress (view at Amazon) is our top choice because you can choose the firmness level that's right for you, and the memory foam is breathable and comfy for hot sleepers. We also love the Zinus Green Tea Memory Foam Mattress for its layers of supportive, pressure-relieving foam.

What to Look for in a Twin Mattress
Firmness
The position you sleep in plays an important role in determining which mattress is best for your needs. For instance, side sleepers tend to be more comfortable on more plush mattresses or products with a pillowtop, while stomach sleepers often prefer a firmer mattress.
Material
Mattresses can be made of several different materials, including memory foam, gel foam, and innersprings. Each has its benefits—for example, gel foam does a great job regulating body temperature, while memory foam contours to your body for a comfortable night’s sleep.
Thickness
Mattress thickness often impacts how comfortable the product is. Thin mattresses tend to be less expensive, but they often wear down faster and provide less support. A mattress that’s at least 10 inches thick is likely more comfortable, but you may want one that’s bigger or smaller depending on factors like budget, weight, and age.
Standout Features
Third-party certifications
Because you'll be sleeping on your new mattress night after night, you may want one that's been third-party tested for consumer safety. For example, a foam mattress with CertiPUR-US certification is free of heavy metals, ozone depleters, and other potentially harmful chemicals. Similarly, mattresses with OEKO-TEX Standard certification have also been tested for potentially harmful substances.
Breathability
To help keep you comfortable throughout the night, you'll want to consider the breathability of your new mattress. Foam mattresses tend to be hot for some sleepers, so you may want one made with ventilated foam to allow airflow. Choosing a mattress with a breathable cover, such as one made from 100 percent cotton, can also help you stay cool.

What are the dimensions of a Twin mattress?
The standard size for Twin mattresses is 38" wide by 75" long, however some measure up to 39" wide. In terms of depth (height), most Twin mattresses are 10" - 12" deep, but some, especially those that arrive rolled up in a box, are as little as 6" deep.
-
What is the difference between a Twin and a Twin XL mattress?
Twin XL mattresses are "extra long", giving you an additional 5" for a total length of 80" as opposed to 75". This is a definite plus for anyone over 5'9" tall, or anyone who prefers to have extra leg room or space for additional pillows.
-
How long should a Twin mattress last?
As a rule of thumb, most modern mattresses should last 7 to 10 years. That said, thinner mattresses made with low-quality materials will likely start to sag or become uneven in as little as 4 years. A good memory foam mattress pad can help extend the life of an older mattress,
