Amerisleep AS3 The Amerisleep AS3 mattress is 12 inches tall and contains 3 inches of Bio-Pur®, 2 inches of Affinity with HIVE® technology, and 7 inches of Bio-Core®. With a medium feel, the AS3 is great for side and combination sleepers— responsive, CertiPUR-US® certified foams conform to the body for excellent pressure relief without making the sleeper feel “stuck.” Switching between sleep positions is also easier on the AS3. The mattress cover incorporates FDA-determined Celliant® technology— the material is made up of thermoreactive yarn designed to transform body heat into infrared energy. The body reabsorbs this energy, leading to better rest and a more rejuvenating morning. Bio-Pur® is a plant-based memory foam— manufacturers partially replace petroleum with castor oil to produce a foam more breathable and responsive than traditional memory foam. Bio-Pur® conforms to the body, relieving pressure points, particularly in the shoulders and hips, since more pressure builds up in those areas. The Affinity foam layer uses HIVE® technology to form a 5-zone support system— hundreds of hexagonal-shaped segments are clustered together to form firmer support to the head, back, and legs with softer support to the shoulders and hips. HIVE® evenly supports the body and relieves pressure points in heavier sections of the body. Bio-Core® is a durable foam made to reinforce the top comfort layers and prevent the body from sinking down too far into the mattress. Warranty and Sleep Trial 20-Year Warranty Amerisleep includes a 20-year warranty with each mattress purchase. This warranty covers manufacturing defects and sagging greater than 0.75 inches. During the first 10 years, Amerisleep will repair or replace the mattress free of charge to the customer. During the last 10 years, Amerisleep will choose to repair or replace the mattress at a prorated charge to the customer, depending on how long they’ve had it. 100-Night Sleep Trial The AS3 includes a 100-night trial. During this time, the customer can try out the AS3 in the comfort of their own home. While Amerisleep doesn’t require a mandatory test period, they do recommend the customer keep the mattress for at least 30 days, because it takes about that long for the body to adjust to a new mattress. At any point, if the customer isn’t satisfied with the mattress, Amerisleep will work with the customer to have it picked up and donated before issuing a full refund. 2. Zoma The Zoma Mattress is 11 inches thick and contains 2 inches of Triangulex™, 2 inches of Reactiv™, and 7 inches of Support+. The Zoma is marketed as a mattress for athletes and those with an active lifestyle, but its sleep-promoting technologies can upgrade anybody’s night’s sleep. The medium-firm feel of the Zoma mattress makes it great for any sleep position. The mattress compresses more deeply under heavier sections of the body, relieving pressure. Breathable, CertiPUR-US® certified foam conforms to the body and may reduce inflammation with its cooling properties. The breathable polyester knit fabric cover wicks away moisture and regulates temperature. Triangulex™ is a foam layer containing hundreds of triangular-shaped segments formed into a 3-zone support system— the areas under the head, shoulder, and legs offer a softer feel, while the section under the back and hips is firmer. Topped with cooling gel to absorb and disperse heat, Triangulex™ relieves pressure points without overheating. The latex-like feel of Reactiv™ foam contours to the body’s natural curves while providing a responsive bounce, making movement easier. Reactiv™ also isolates motion, leading to fewer sleep disruptions from movement. Support+ is a high-density foam base that consistently supports the body without risk of sagging. It also enhances pressure relief in the hips and shoulders while encouraging healthy spinal alignment. Warranty and Sleep Trial 10-Year Warranty Zoma offers its customers a 10-year warranty with the purchase of any mattress. The warranty protects against any manufacturing defects which could damage the foam bed, and sagging greater than 0.75 inches. During the 10-year period, Zoma will repair or replace the mattress at no extra charge to the customer. 100-Night Sleep Trial Zoma includes a 100-night sleep trial for its customers, with the recommendation that they try the mattress for at least 30 days to allow the body to adjust to a new sleep surface. If the customer is not happy with the mattress, Zoma will arrange to pick up and donate it before issuing a full refund. 3. Nolah Signature 12 The Nolah Signature 12 mattress is 12 inches tall and contains 2.5 inches of AirFoam™, 1.5 inches of high-resilience foam, 7 inches of high-density foam, and 1 inch of AirFoam™. All four foam layers of the Nolah Signature 12 mattress are CertiPUR-US® certified, meaning the foam is created without harsh chemicals, including formaldehyde. The flippable design of the Nolah Signature 12 mattress is perfect for versatile sleepers who may want to switch between a soft and firm surface. The softer side is great for side and back sleepers who need enhanced pressure relief in the shoulders and hips, while the firm side is ideal for combination and stomach sleepers who need firmer support to keep their bodies resting on top of the surface. The unbleached, organic cotton cover provides a soft, plush sleep surface and enables excellent breathability for a more restful night. Cotton wicks away moisture and keeps body temperature consistent, no matter the season. The thick top layer of AirFoam™ offers a softer feel and conforms to the body to relieve pressure points— it acts as a deeper cushion for the shoulders while cradling the hips. AirFoam™ is scientifically proven to reduce pressure points more effectively than traditional memory foam, without leaving sleepers feeling trapped inside the mattress. High-resilience foam is stronger and more durable than latex, giving a responsive bounce to encourage healthy spinal alignment and to make movement easier during sleep. The high-density support foam reinforces the contouring and support of the top layers. The support layer also evenly distributes body weight across the sleep surface. This foam layer is so durable, Nolah warrants this support foam will last a lifetime. A thin layer of AirFoam™ acts as both the base layer and the comfort layer when flipped to the firm side. The firm feel of this responsive foam relieves pressure points and keeps combination and stomach sleepers resting on top of the mattress, preventing the body from sinking too deeply. Warranty and Sleep Trial Lifetime Warranty Nolah provides customers with a lifetime warranty with the purchase of the Nolah Signature 12 mattress. The warranty lasts as long as the original purchaser owns the mattress. During the first 15 years, Nolah will repair or replace the mattress free of charge to the customer. After the 15th year, Nolah can choose to either repair or replace the mattress at a prorated charge. 120-Night Sleep Trial The Nolah Signature 12 mattress comes with a 120-night trial— Nolah requires customers to keep the mattress for at least 30 days to adjust to the new bed. After the first 30 days, if the customer isn’t happy with the mattress, Nolah will arrange to have the bed picked up before issuing a full refund. 4. Original Purple® The Purple® mattress is 10 inches thick and contains 2 inches of the Purple Grid™, 3.5 inches of poly-foam, and 4 inches of high-density poly-foam. These three layers of foam cradle the body, relieve pressure points and fully support the back. The Lycra® blend cover is a stretchy knit material designed to allow air to pass through, evening out body temperature instead of trapping heat. The Purple Grid™ contains Hyper-Elastic Polymer™, a stretchy, gel-like temperature neutral material formed into an open grid system for better air circulation. The Purple Grid™ is constructed to flex underweight, relieving pressure points without losing support. The poly-foam transitional layer cradles the body and aligns the spine. The high-density poly-foam base evenly supports the body without sagging, and it’s made from durable material to help the bed last for years. Warranty and Sleep Trial 10-Year Warranty Purple® includes a 10-year warranty with the purchase of the Purple® mattress, covering cracks or splits in the foam from regular use and sagging greater than 1 inch. During the 10 years, Purple® will repair or replace the mattress free of charge to the customer. 100-Night Sleep Trial The Purple® mattress comes with a 100-night sleep trial. Purple does ask its customers to keep the mattress for at least 21 days before they’ll allow any returns. If the customer is not happy with the mattress, Purple® will pick up it up and then issue a refund. 5. Bear Pro The Bear Pro mattress is 12 inches thick and contains 1 inch of copper-infused foam, 1.5 inches of gel memory foam, 2.5 inches of responsive foam, and 7 inches of high-density foam. The medium-firm feel of the Bear Pro mattress provides extra cushioning to the shoulders and hips, reducing pressure points without making the sleeper feel “stuck” inside the bed. The Bear Pro is great for all types of sleepers, particularly combination sleepers— they need a medium-firm surface to consistently keep the spine in neutral alignment and provide a balance of comfort and support no matter the sleep position. The cover is infused with FDA-determined Celliant® technology, transforming body heat into energy. Celliant® regulates temperature and may improve muscle recovery. The conductive properties of copper provide a cooler sleep when incorporated into the top comfort foam layer of the Bear Pro mattress. Copper pulls heat away from the body and may improve local blood flow. The antibacterial properties of copper also deter bacteria and dust mites. Gel memory foam further ensures the body stays cool by absorbing and evenly dispersing body heat. Both the copper-infused foam and gel memory foam contour to the body, relieving pressure points and reducing tension in the back, hips, and shoulders. The responsive foam acts as a transitional layer between the plush comfort layers and the support layer. The foam prevents the body from sinking too deeply inside the mattress and encourages healthy spinal alignment. The high-density foam keeps the mattress stable and supports the body without sagging. Warranty and Sleep Trial 10-Year Warranty Bear provides a 10-year warranty with the purchase of the Bear Pro mattress. The warranty covers physical flaws that could cause cracks or splits in the foam and sagging greater than 1 inch. During the 10 years, Bear will repair or replace the mattress, but the customer will be responsible for shipping and handling costs. 100-Night Sleep Trial The Bear Pro mattress comes with a 100-night trial, where customers can try out the mattress at home. If, at any time during this trial period, the customer isn’t satisfied with the mattress, Bear will arrange to pick it up before issuing a full refund. Benefits of a Twin Size Mattress Twin mattresses come at a lower price, because of their small, narrow size. Perfect for limited living spaces, twin-size mattresses are perfect for studio apartments and guest rooms. Children and seniors most commonly sleep on twin size mattresses. Single adults tend to gravitate toward larger sizes, like full, queen, or king sizes, but for those on a budget, a twin-size is a good choice. Twin vs. Twin XL vs. Full When deciding on the right mattress size, especially if the bed is meant for a smaller space, take note of the difference in sizing between the three smallest mattress sizes— twin, twin XL, and full. Twin Size Mattress A twin size mattress is 38 inches by 75 inches and is the smallest standard mattress size available. A twin size is meant for one person and anyone under 6 feet2 inches tall. They’re also a great choice for kids because they’re compatible with small sizes and they fit growing bodies. Twin size mattresses are widely available from different brands. Their compact size could make room for more than one bed in a bedroom. Twin XL Size Mattress A twin XL size mattress is 38 inches by 80 inches, about half the size of a king size mattress. Twin XL beds are the same size as twin mattresses, except they’re 5 inches longer— great for taller people 6 feet 7 inches or shorter. Twin XL beds are meant for one person and are usually in college dorm rooms and hospitals. Full Size Mattress A full size mattress is 54 inches by 75 inches and meant for one to two people. With more space, a full size bed is perfect for combination, or restless sleepers, who regularly toss and turn at night. Full size mattresses are a good choice for teenagers and young adults. What to Look For in a Twin Size Mattress Before committing to a new mattress, consider the features in a mattress like the thickness, firmness, price, mattress type, sleeping position, and sleep accessories. Also check out what type of sleep trial, warranty, and return policy is included with the new mattress. Thickness The thickness of a mattress could determine the amount of support you’ll receive from a new bed. The heavier the weight applied to the bed, the thicker the mattress should be to keep the bed from bottoming out. Thin mattresses tend to wear down faster and are more likely to sag; on top of that, they typically have less support and pressure relief. When choosing a mattress, don’t go thinner than 8 inches for adults. If the bed is meant for a child, you could choose a thinner mattress— children don’t need a thick mattress if the bed is not meant to last into their teen years. Plus, thinner mattresses are great for bunk beds. Firmness How firm you want the mattress depends on your body type and sleep position, but any type of firmness should provide a balance of comfort and support while keeping the spine aligned. Lightweight sleepers need a softer surface to allow their bodies to slightly sink into the mattress for pressure relief, while heavier individuals need a firmer feel to support their bodies without sagging. Average weight people do best on a medium mattress. Sleeping Position As mentioned before, your favored sleep position impacts what mattress you choose. Each sleep position needs the right level of cushioning and support to keep the spine in alignment and ensure a good night’s sleep. Side Sleeping Side sleeping is one of the most popular sleep positions, plus it’s one of the healthiest. Side sleeping enables better breathing by opening up airways, and it reduces acid reflux and minimizes pressure on vital organs like the heart. The best mattresses for side sleepers are typically medium or soft in firmness in order to fill in the large gaps between the body and the sleep surface. Placing a pillow between the knees helps stabilize and better align the spine. Back Sleeping Back sleeping is another healthy sleep position, though it does come with some risks, including snoring potential and developing sleep apnea. Lying on the back at night naturally aligns the spine because of the back’s direct contact with the sleep surface. We recommend medium to firm mattresses for back sleepers to better support of their lower backs and prevent heavy sinking. Their mattress should relieve pressure points in the shoulders and hips, where body weight is typically heaviest. Stomach Sleeping Stomach sleeping is one of the least common sleep positions because of the intense pressure it places on the spine. High pressure can lead to neck strain and back pain. If possible, try to switch to side sleeping as a healthier alternative sleep position. For committed stomach sleepers, a medium-firm to firm mattress is the best choice— the body will remain resting on the surface without sinking deeply, which can throw off spinal alignment. For extra support and to reduce the pressure on the spine, place a thin pillow under the hips. Combination Sleeping Combination sleepers, or restless sleepers, switch between two to three different sleep positions each night— they need a medium to medium-firm mattress to provide a balance of comfort and support for each sleep position while keeping the spine in alignment. Price Before buying a new mattress, set a budget based on the type of mattress you’re looking for. The price will depend on the kind of materials a bed contains— expect to pay more for natural, organic materials like organic cotton and natural latex. Since twin size mattresses are the smallest standard size, they’ll have a lower price point compared to a queen size. The average price for a twin mattress is between $200 to $1200. Mattress Type There is no such thing as a “one size fits all mattress”— each type of bed offers potential buyers their own unique feel, like the contouring ability of memory foam or the supportive bounce of an innerspring. Take a moment to consider each mattress type before choosing your best mattress. Memory Foam Mattress A typical memory foam mattress contains a comfort layer of memory foam and a support layer of high-density foam. Memory foam is a popular choice in the mattress market today because of its excellent pressure-relieving, contouring abilities. Memory foam also isolates motion transfer and makes no noise, so sleepers are less likely to wake from their partner’s movements. Memory foam does trap heat because it’s so dense, but manufacturers have improved memory foam by adding cooling properties to, like gel. They’ve also infused traditional memory foam with copper and graphite to pull heat away from the body. Innerspring Mattress An innerspring mattress contains a thin comfort layer of foam or fiberfill (usually a pillow top) and a support layer of steel coils. Innerspring mattresses are best known for their bouncy surface and naturally cool feel because air can circulate freely inside the support layer. Compared to other types of mattresses, innerspring beds provide less pressure relief because their comfort layers aren’t thick enough to adequately cushion the body. Innerspring mattresses also have more noise potential due to the creaky steel springs. Latex Mattress Generally, a latex mattress contains a comfort layer of latex and a support layer of either latex or high-density foam. Natural latex comes from rubber tree sap— Dunlop is 100% natural and present in both latex and hybrid mattresses. Talalay is another type of latex, but unlike Dunlop, polyurethane fillers are added during processing, giving it its popular sponge-like feel. Latex mattresses are like memory foam, except they’re cooler and don’t conform as close to the body to relieve pressure points. Latex also has a responsive bounce, making movement easier. A drawback to latex is its high price point— latex is more expensive than other mattress materials, especially if the bed contains natural latex. Hybrid Mattress A hybrid mattress contains a comfort layer, at least 2 inches, of memory foam or latex, and a support layer of pocketed coils. Hybrid mattresses combine the features of both memory foam and innerspring beds— they have excellent pressure relief, responsive bounce, and are cool. Hybrid mattresses are heavier and more expensive than other mattress types because they contain so many materials. Accessories Using sleep accessories like bunk beds and mattress protectors with your twin size mattress saves space and extends the life of the mattress. Bunk Beds Bunk beds are a great foundation choice, particularly for children sharing a room. Bunk beds save on space by stacking vertically two to three bunk beds in a room— some models can be separated into individual bed frames. Potential buyers can also save money by choosing a bunk bed because bunks don’t need headboards, mattress foundations, or box springs; they only need a twin or full size mattress. Bunk beds may also be a good choice for those caring for a senior who needs constant care— the caregiver can sleep in the same room without worrying about accidents. Mattress Protector Investing in a mattress protector can not only extend the life of the mattress, but it can also protect the bed’s warranty— most warranties become void if the mattress takes on any damage from spills or stains. Many high-quality mattress protectors cost under $40, a small amount compared to the $200-$1200 cost to replace a mattress. Sleep Trials, Warranties, and Return Policies Sleep trials, warranties, and return policies are nice perks that reassure customers of a sound purchase. Avoid any mattress missing a sleep trial or return policy and warranty, as that could be a sign of a poorly-made mattress. Sleep Trial Sleep trials enable customers to try a new mattress in the comfort of their own homes without the pressure from salesmen. Most sleep trials last between 90 to 120 nights, depending on the brand. Should the customer not like the mattress, most companies will arrange to pick up the bed before issuing a full refund. Warranty Warranties protect the mattress from manufacturing defects which could cause damage to the bed and sagging greater than 1 inch— the measurement depends on the brand since some go as low as 0.75 inches and others as deep as 2 inches before accepting any claims. Return Policy Return policies are a good substitute if a sleep trial isn’t available. A return policy lasts about 30 days, the same amount of time it takes most people to adjust to a new sleep surface. If the customer isn’t happy with the mattress, they can return it for a full refund. FAQs How much should a good twin mattress cost? Expect to pay between $200 to $1200 for a good-quality twin size bed. The mattress materials should last between 7 to 9 years and include a standard 10-year warranty. Is a twin bed the same size as a single bed? Twin and single beds are the same size— both measure 38 inches by 75 inches. What is the best size bed for couples? Twin, twin XL, and full size beds are too small for couples. Queen, king or California king sizes are better for couples, because it gives more room for both sleepers to move around— larger size beds are especially great for combination sleepers who like to toss and turn most of the night. Conclusion Most twin size mattresses come with all the same features as any size mattress— the only difference is price and size. Because they’re smaller, twin size mattresses are less expensive, making them an excellent choice for those with a tight budget and limited living space.
