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. FullWhen 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 MattressA 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 MattressA 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 MattressA 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 MattressBefore 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.ThicknessThe 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.FirmnessHow 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 PositionAs 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 SleepingSide 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 SleepingBack 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 SleepingStomach 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 SleepingCombination 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.PriceBefore 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 TypeThere 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 MattressA 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 MattressAn 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 MattressGenerally, 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 MattressA 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.AccessoriesUsing sleep accessories like bunk beds and mattress protectors with your twin size mattress saves space and extends the life of the mattress.Bunk BedsBunk 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 ProtectorInvesting 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 PoliciesSleep 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 TrialSleep 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.WarrantyWarranties 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 PolicyReturn 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.FAQsHow 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.ConclusionMost 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.
