Updated September 10, 2020Doctors used to prescribe a very firm mattress for those suffering from low back pain, but it’s no longer the common thinking. In fact, a recent survey of 268 people with low back pain found dormers who had a very firm mattress had the poorest sleep quality. On the other hand, a mattress that is too soft and lacks sufficient support can lead to an achy back in the morning. This is because with your hips sinking in, you may feel increased pressure on your lower back.To help you find the best soft mattress, this article will cover several factors such as sleeping position, weight, and lifestyle. Plus, we will go over ten popular mattress brands and see what features they offer.Best Soft MattressBest Soft Mattress of 2020: Amerisleep AS5Best Cooling Soft Mattress: Zoma MattressBest Budget Soft Mattress: Vaya MattressOur Top Mattress RecommendationView on AmerisleepRead AS5 customer reviewsAS5 Highlights100-night sleep trial20-Year WarrantyDesigned to reduce pain pointsHeat reducing mattress coverComes in King, Queen, Twin, Full, and SplitsOur Runner-UpView on ZomaRead Zoma customer reviewsZoma Highlights100-night sleep trial10-Year WarrantyDesigned for faster recoveryTriangulex™ technology promotes healthy postureComes in King, Queen, Twin, Full, and SplitsBest Soft MattressesMattressHighlightsPriceAmerisleep AS5Plant-based memory foam and highly-responsive foam relieves pressure points without sagging.$1539ZomaCooling, 3-zone support memory foam evenly supports the body and may improve muscle recovery.$850VayaSoft, responsive memory foam forms around the body for cushioning comfort.$578Luxi 3-in-1Interchangeable foam layers provide a customized support system.$1049TuloSoft feel of cooling gel memory foam absorbs and disperses body heat.$499Nolah Signature 12Flippable mattress with a soft and firm side for a versatile feel.$1269Bear ProBoth gel and copper-infused memory foam pulls heat away from the body and may improve local blood flow.$1050Nest Bedding Alexander Signature HybridPlush feel of foam comfort layers combined with supportive pocketed coils for better sleep.$1299Zinus Cooling GelBudget-friendly option with a cooling gel comfort layer for a plush feel with little risk of overheating.$2461.

There are also choices like latex and hybrid beds. There are benefits and drawbacks to each of these types.Innerspring MattressesInnerspring mattresses use multiple coils to offer support, which are topped with an array of materials for added comfort.For soft mattress lovers, this is typically a pillow-top cover.Experts warn to steer clear of the cheapest innerspring mattresses, which lack enough coils for support.Memory Foam MattressesMemory foam mattresses have been exploding in popularity in recent years. They are designed to mold to your body throughout the night to reduce pressure points. They also absorb movement so co-sleepers don’t notice their partners shifting throughout the night. If you have a hard time getting comfortable or suffer from chronic pain, a memory foam mattress might be the solution. Memory foam is also great if you love a cozy, cradled feeling during sleep.One of the concerns about memory foam is they can have off-gassing, which is the chemical, new-mattress smell when you unload the box. With inexpensive foam, the smell may not dissipate. Keep an eye on brands that offer greener varieties of memory foam as they won’t have this stinky issue.Another complaint is that memory foam can trap heat. Newer mattresses are introducing open-cell and plant-based technology to combat this problem.Latex MattressesLatex mattresses are an eco-friendly option since it is made from an entirely natural material. To enjoy the all-natural aspect, you’ll want to make sure the mattress is 100% latex, and not mixed with other fillers. The feeling is similar to memory foam and its body-conforming properties. Latex mattresses are a great option for anyone with allergy and asthma issues.On the other hand, latex mattresses are one of the more expensive options. The material is also very heavy, so make sure you have someone around to unload it. To prolong its life, your latex mattress should be rotated or flipped every six months.Hybrid MattressesHybrid mattresses are somewhere in between innerspring and foam. The foam layers can be made up of memory foam or latex. They are designed to offer the best of both worlds when it comes to bounce-back and support.Hybrid mattresses may not be the best if you share a bed, however. Due to this extra bounce, they aren’t great at motion isolation, and you might feel more movement throughout the night. Hybrids too are one of the pricier options on the market.Difference Between a Firm and Soft MattressIt may seem obvious, but the difference between soft and firm mattresses is a little more complicated than you think. Most mattress companies have a firmness scale between 1 and 10. Soft mattresses are typically between 3 and 5, with firm mattresses coming in above 7. Meaning, a 1/10 firmness is too soft for even the squishiest mattress lover. Pillow top mattresses, for example, are too soft and don’t offer ample support.A firm mattress will be rigid to the touch with less give, while a soft mattress will compress easier when weight is applied. But even the softest mattress shouldn’t swallow you up or make you feel like you’re stuck. You’ll want bounce-back because when you move around in the night, the bed should still support you. Be sure to read reviews about support and pressure relief before buying the softest mattress you can find.See Also: Best Mattress of 2020Who Should Use a Soft MattressThe best mattress firmness varies by each person’s body type, lifestyle, sleeping position, and personal preference. Soft mattresses are best for people under 230 pounds. They may not be supportive enough for people over 230 pounds.If you have back pain, a firm mattress can actually make you feel worse. Soft mattresses are recommended for sleepers with pre-existing spinal issues.Do you run cold? Soft mattresses offer more warmth, so they’re great for cold sleepers or older people who tend to have lower body temperatures. Side sleepers will also be most comfortable on a softer mattress. More cushion will better contour to hips, shoulders, and neck if you sleep on your side. Because those who suffer from sleep apnea should sleep on their side, a soft mattress can be beneficial.Who Should Avoid a Soft MattressStomach and back sleepers will find firm mattresses offer improved support. Co-sleepers may also want more firmness. If one sleeper is heavier than the other and the mattress is too soft, it may cause the bed to be uneven and affect one or both of the sleeper’s comfort.Your soft mattress may not last as long as a firmer model, so avoid this choice if you’re looking for the longest possible amount of time out of a mattress. While all mattresses become softer overtime, softer mattresses tend to show the effects sooner.Frequently Asked QuestionsWhat is the softest mattress on the market?It’s hard to say since body weight plays a big role in the perception of firmness. For example, sleepers over 230 pounds are going to find most beds feel softer than advertised. On the other hand, sleepers weighing less than 130 pounds typically find beds feel firmer than anticipated. The softest mattresses, though, are those rated 2 or 3 on the firmness scale.Who are soft mattresses good for?Softer mattresses are typically loved by side sleepers because they can alleviate pressure and pain in the shoulders and hips. Some back sleepers also enjoy the feel of a cushioning bed, but stomach sleepers need very firm mattresses to feel comfortable.What’s the softest mattress type?All mattress types are made in a variety of firmness options, but memory foam beds are typically considered the softest for their cradling feel. Latex mattresses are more responsive, so they tend to have a firmer feel than memory foam, and beds with coils are very bouncy.How do I know if my mattress is too soft?Your mattress should be firm enough to keep you lifted and maintain neutral spinal alignment. You can tell if your bed is too soft if you feel your hips sinking below your torso, you wake up with lower back pain or stiffness, or you struggle to get comfortable at night. Soft mattresses with zoned support technologies can prevent this kind of discomfort and facilitate neutral spinal alignment.Are soft beds good for your back?Not necessarily, many of the best mattresses for back pain have a medium-firm or medium feel because these beds can maintain proper sleeping postures and prevent aches and pains from forming as a result of sinking too far in the bed. That’s not to say soft mattresses are bad for your back, though—petite sleepers often find soft mattresses very comfortable and don’t experience any back pain with them.Sweet Dreams, Soft Mattress LoversThere’s a common misconception that anyone with lower back pain should pick a firm mattress. But if you love the sinking feeling of a soft mattress, don’t worry. The best options on the market offer impressive contouring and pressure relief.The type of mattress you choose will also have an effect. All-foam mattresses can offer impressive support and spinal alignment. Many combine several support layers so you can still have a plush, cozy feeling you like without getting stuck in your mattress. It can be tempting to choose a pillow top for a cloud-like feeling, but it may not be supportive enough for larger people. Do your research to find the right combination for your body weight and sleep style.This article is for informational purposes and should not replace advice from your doctor or other medical professional.
