Here we’ve provided a guide for those who may feel most comfortable sleeping on a medium-firm bed.Back and Stomach SleepersWhile soft and medium mattresses suit side and combo sleeping well, we suggest medium-firm and firm mattresses for back sleeping. Stomach sleeping, ideally, should be avoided entirely; however, medium-firm mattresses work for stomach sleepers, too. Sleeping flat on your back or belly can cause the torso and heavier sections of the body, like the hips and shoulders to sink in the mattress, especially if the mattress is too soft. Over time, this causesPlus-Size SleepersThe more you weigh, the more support you need. Plus-size sleepers who weigh more than 230 pounds need a mattress with a little more lift to achieve a comfortable and healthy night’s sleep. Softer beds lack adequate support and sag, leading to back pain—that’s why many of the best mattresses for heavy people are firmer or built with extra support layers.People with Back PainBack pain affects 31 million Americans each year and disrupts sleep. A medium-firm mattress provides better support to the lower back and cradles the hips, relieving pressure along the spine and reducing pain. Softer mattresses may place more pressure on the spine and worsen back pain.Read More: eachnight’s Guide to Finding the Best Mattress for Back PainWhat to Consider in a Medium-Firm MattressBefore you buy a mattress, consider your budget, preferred mattress type, and company policies, including a sleep trial and warranty. The right mattress provides long-lasting comfort and support without breaking the bank.PriceMattresses are an investment, with some budget mattresses starting at $200, while high-end models cost well over $10,000. The average price you can expect from mid-range medium-firm mattress models (in queen size) is between $500 to $1200.The best way to distinguish a quality mattress from a cheap model is by looking at the mattress layers. If the mattress is made with poly-foam or innerspring coils, it’s likely to wear down quickly. Also, if the mattress is less than 10 inches thick, it probably won’t hold up to continuous use.Mattress TypeMedium-firm beds come in various materials, each with its own set of pros and cons. The best mattress type for you depends on your sleep position, budget, and personal preference.Some materials may cost more than others; for instance, latex often comes with a higher price tag because it’s 100% natural and long-lasting. Memory foam is a cheaper alternative with a 7-10 year lifespan.Memory Foam MattressesMemory foam mattresses are the best choice for those looking for a material to conform to the body, wanting that “hug” sensation. Memory foam contours to the body’s shape and sleep position, relieving pressure points and providing healthy alignment.The top layer contains memory foam and a durable base foam for support. Memory foam makes little to no noise and it limits motion transfer, so there’s less chance of waking in the night due to your partner’s movements. It’s also hypoallergenic, making memory foam particularly ideal for those who suffer from allergies.Latex MattressesLatex is a natural material that comes from the sap of rubber trees. Eco-friendly and hypoallergenic, many consumers like latex because it’s similar to memory foam—forming around the body for pressure relief. Latex also has excellent motion isolation and sleeps silently, but unlike memory foam, it sleeps cooler and has a responsive bounce.Latex mattresses are typically more expensive because the manufacturing process is eco-friendly. The two most popular types of latex are Dunlop and Talalay—Dunlop is 100% natural, plus it’s denser and more durable than Talalay. Talalay consists of natural latex with added polyurethane fillers to give it that signature soft feel.Innerspring MattressesInnerspring mattresses are made up of steel coils that either stand-alone or interlock with each other. Most innerspring mattresses include a comfort layer made of fiberfill or foam for pressure relief, but some brands have the option to add a pillow top for extra comfort. It might be a good idea since innersprings lean more towards the firm side.Innersprings offer excellent breathability with the open airflow from the coils but may lack pressure point relief. This type of mattress will have a definite bounce and may be noisy due to the coils.Hybrid MattressesA hybrid is a combination of innerspring and memory foam. A hybrid mattress has coils for support and a 2-3 inch memory foam comfort layer. The number of memory foam layers will vary depending on the manufacturer, but you can expect 1 to 2 comfort layers in a medium-firm hybrid mattress.Many see hybrid beds as the best value because of their 2-in-1 construction: contouring memory foam with a coil support system. However, hybrids are heavy compared to other mattress types, making them cumbersome to move.Sleep Trial and WarrantyAlmost all mattresses these days come with a warranty, and online beds often come with sleep trials. We recommend purchasing a mattress with both. Always read the fine print before committing to a mattress purchase and avoid beds that don’t include a warranty or a means to return the bed if it doesn’t work out.Sleep trials enable customers to try a new mattress within the comfort of their own home. Most trial periods last between 90 to 120 nights to allow the customer ample time to adjust and decide. Should the customer not like the mattress, most companies will issue a full refund.Most mattresses come with a standard 10-year warranty that covers manufacturing defects and sagging greater than 1 inch. Warranties only apply to the original purchaser and can’t be transferred to another person.FAQsCan a firm mattress hurt your back?If a mattress is too firm for your preferred sleep style, it can cause painful pressure points and lead to back pain. Likewise, a too-soft bed causes heavier sections of the body, like the shoulders and hips, to sink too deeply, misaligning the spine. It’s best to sleep on a bed with the right balance between comfort and support, depending on your sleeping position. Otherwise, a too-soft or too-firm mattress disrupts sleep, and you wake up sore.Why does my back hurt after waking up?If you experience back pain and a stiff lower back every morning, which fades during the day, your mattress could be the problem. A bed with a visible sag lacks support for the spine, increasing pressure and the likelihood of back pain. Sleeping on the wrong mattress firmness level can also cause back pain. For instance, side sleepers need a softer mattress for optimal cushioning in the shoulders, or else they feel shoulder pain because their body weight is resting on their shoulder.Is memory foam good for back pain?Memory foam is best for relieving back pain; in fact, we even wrote a whole guide reviewing our favorite memory foam mattresses for back pain. We love memory foam for sleepers with back pain, amongst other pains, because it conforms to the body, providing pressure relief and reducing aches. And at the same time, memory foam holds its shape, so it keeps the body evenly supported. Innerspring mattresses, while supportive, lack pressure relief and don’t form as close to the body as memory foam.Does my mattress need a box spring?Innerspring mattresses are the only mattress type that needs a box spring. The thick coils act as shock absorbers and ensure an evenly supported mattress. Other mattress types, including memory foam, latex, and hybrids, don’t need a box spring and perform well on a flat or slatted surface, like a mattress foundation.Will a firm mattress get softer?A brand new firm mattress may feel hard at first, but becomes slightly softer as you break it in. Most new mattresses feel firmer than the floor model you tried out, which is normal, but after at least 30 days, the new bed should start to feel slightly softer. If the bed still feels too hard, you should be able to return it for a refund or a different model as long as the bed is within its sleep trial.ConclusionNow that you know what to look for in the best medium-firm mattress, it’s time to start looking for the right one. There are many excellent options out there for you to choose from. Keep in mind that the best medium-firm mattress should come with a sleep trial and a warranty, giving you time to try it out and decide if it’s best.About the author Jasmin LeeJasmin Lee is dedicated to helping others get better sleep—when she’s not napping, you can often find her researching the latest in bedding and mattress technology.
