Reviews, Comparison and Buying Guide
Why good King size Innerspring mattress is necessary?
If you’re not getting a good night’s sleep, you’re waking with aches and pains, or you’re just not comfortable in bed, it may be time for a new King size Innerspring mattress. Think about where it hurts—if you wake up with shoulder or back pain, or hip, knee, or other joint pain, your mattress may not be properly cushioned or supportive for you. If your current mattress sags visibly or has a permanent indent in the shape of your body, it’s also likely time for a new one. And if you find that you sleep better in other places (like at hotels or vacation rentals), that’s a red flag too.
Is your King size Innerspring mattress old?
Are you sleeping on the same bed you slept on in your college dorm room or maybe you inherited your mattress from a beloved aunt’s dusty guest room? Be honest. Do you even know how old it is?
Regardless of the warranty, a decent bed only lasts 7-8 years depending on its quality, what it’s made with, and how often it is used.
Is there deformation in the King size Innerspring mattress?
Peel back the sheets and give your sleep space a really good once over. Can you see yourself in it? You really shouldn’t be able to, and if you can, it may not be good for you.
Rotating and flipping (if possible) your mattress regularly can help offset the inevitable formation of body impressions, sagging areas, and dips. However, almost every bed will develop these over time, and they can affect how well it is able to support your body properly and deliver the right amount of comfort.
Has your body size or sleep position preference changed?
A lot can change in 7 or 8 years. Growth, injuries, pregnancies, or sleep position(s): all of these things can affect how we experience a mattress and how we prefer to get our rest. A bed that is perfect right now may be less than ideal 5 years down the road through no fault of its own.
If your body has changed substantially in size or you are sleeping differently than you were when you bought it, you may want to consider replacing it.
Are you experiencing pain?
This should be a no-brainer. A good mattress can offset pain (like back pain) you experience, not cause it! If you are waking up every morning with stiffness in your joints and muscles, your bed may very well be part of the problem.
If your mattress is an incorrect match and does not suit the curves of your shape or weight, you may be sleeping with poor spine alignment or with inadequate pressure relief.
Are you having restless nights?
Waking up throughout the night may be the sign of a medical condition that you should discuss with your doctor, as chronic insomnia can cause long-term health issues. If you suspect your mattress is to blame, examine your comfort system that can result in tossing and turning at night as you try to relieve pressure build up. Excess motion transfer may also be the culprit.
Are you sharing your mattress?
It is very important for couples sharing to find a bed that suits both of their needs. Buying a bed together can ensure that both of you sleep comfortably and can enjoy the level of intimacy you prefer, and with many customizable options, couples who differ in size do not have to sacrifice their own comfort for the sake of their relationship.
Are you in need of an upgrade?
You’re not wearing the same clothes or driving the same car you were in college, so why are you sleeping on the same mattress? Entry-level and budget-friendly beds are fantastic for folks just starting out on their own, but older and more established people deserve an upgrade on their sleep, especially as your body ages and has more critical support and comfort needs.
Best King size Innerspring Mattress Buying Guide : Things to consider while buying a King size Innerspring Mattress
Most people shop for mattresses all wrong by focusing on arbitrary measures of firmness level or sleep position, considering only the price, or simply choosing the materials and technology touted in an ad. But that approach can land you a not-so-comfy mattress you may regret buying. The advice in this guide will show you a better way. It builds on our hundreds of hours of research and sleep testing to help you find a mattress you’ll happily sleep on for years.
Type of Mattress
Despite what the internet and mattress salesmen may want you to believe, there is no any one material that is superior to another. Each person has their own list of preferences, which hopefully you have established by reading this guidance.
An innerspring mattress may be the most commonplace and it’s likely that you’ve slept on this type of bed at least once in your life. In recent years, there’s been a lot of development of what we consider a traditional coil system, and it’s good to know the advantages and disadvantages of the different features you might encounter.
- What are different coil configurations?
Configuration of your coils may affect how motion transfers, the bed’s ability to contour to your shape and its overall long-term durability.
Bonnell coils are very common in mid-level beds and are shaped like hourglasses. In slightly higher-end beds, offset coils offer slightly better pivot and contouring ability with a hinged, squared off top and bottom. Both Bonnell and off-set offer a more classic experience.
Newer beds may include what’s called continuous wire, which uses one wire to build the entire system, which may offer slightly more stability than traditional systems. Conversely, individually wrapped coils are a modernization that can offer enhanced body contouring and motion isolation..
- What is coil gauge?
Mattress gauges range from around 12 to 16. The higher the number, the more flexible the coil will be, contributing to a “softer” feel overall. Thicker wires have been shown to feel much firmer and may offer enhanced durability over the long-term.
- What does coil count mean?
Many brands provide their coil count as a sign of the bed’s quality, and beds with higher coil counts may provide enhanced support and durability. However, more is not always more, and beds with a coil count above the minimum standard of about 400 for a Queen do not demonstrate significant advantage in longevity.
- Is coil-on-coil better?
Using more than one type of coil system can harness the advantages of multiple styles by offering body conformance in a top layer of coils and enhancing the bed’s support system by using a sturdier construction down below.
All-foam beds are a more modern development and can feel quite different to sleepers who’ve been resting on springs for most of their lives. There are many different kinds of foams of various densities and firmnesses which can change up the experience, and there are several terms you might encounter.
These beds are typically built with polyurethane foams, formulated using petro-chemicals or sometimes more bio-based oils. Densely formulated or visco-elastic foams, often called memory foams, are a type of poly foam. Latex, either all-natural or synthetic blend, may also be included in an all-foam construction.
- Is responsiveness important?
All materials respond to pressure differently, but responsiveness is often discussed with foams, especially at the surface of a bed. Mattress foams with a slower response may be difficult to move around in, while quick-responding materials are springy to the touch and may even have some bounce (though usually not as much as a spring might).
- What is closed vs. open cell?
Closed-cell poly foams are typically much more dense and resistant to airflow, making them superior at insulating temperature and providing structural support. Open-cells feel softer because air travels through quickly when pressure is applied to them, and their increased airflow also helps keep these materials from overheating.
- How does Indentation Load Deflection (ILD) factor?
Some foams are discussed in terms of how many pounds of pressure are required to compress the foam by 4 inches. The more pressure required (or higher ILD) the firmer the foam typically is.
- What do densities mean?
The density of foam can be deceiving as different densities have different implications for different kinds of foam. For standard polyfoam, denser foams are often firmer and usually make up the base or support of an all-foam bed. Typical all-foam bed bases have a density of about 1.8.
- Why is all-foam great at motion isolation?
Foams are used in multiple industries to keep vibration muffled because of their ability to absorb energy at the source and preventing it from moving across the surface. This is great news for light sleepers.
Though memory foam beds are a kind of all-foam construction, they deserve their own category because of their unique properties and advantages. There are several misconceptions surrounding memory foam that you should be aware of when shopping for a new bed.
Memory foam beds were all the rage in the 1970s and 80s when the material was first developed by NASA to cushion astronauts in space. Traditionally, memory foam reacts to heat and pressure to slowly conform around the object (or person!) resting on it.
It gets its name from the fact that it often leaves an impression of that object, even after pressure is removed. Classic memory foam offers tight body conformance, super slow response, and often retains heat.
- What does density mean in memory foam?
For memory foam, density refers to how much one square foot of the material weighs. Extremely dense memory foam (5 and above) is slowest to respond and can often make you feel like you’re crawling around in quicksand. These foams are often found (in varying amounts) in high-quality memory beds and provide a classic and more durable experience.
Lower density memory materials (2-4) are much more responsive to pressure and allow air to flow easier so they are less likely to retain heat, so they are much cooler and easier to move around on. These foams may, however, have a tendency to break down quicker over time compared to higher densities.
- Why does some memory foam have gel?
To offset some of the heat retention concerns of classic memory foam, many brands have incorporated gels into their formulations to compensate for temperature concerns of minimal airflow. This gel helps to redirect heat away from the body and keep it from building up against where you’re resting.
- Is memory foam full of chemicals?
In the early days of this type of material, there were concerns about its flammability and chemicals contained in its construction. Modern memory beds often come with certifications that guarantee consumer-safe levels of potentially harmful materials and emissions. Better quality beds often have more than one certification, and all foam beds are required by law to incorporate flame retardants.
Latex mattresses are usually (but not always) made from the milky white sap of the Hevea Brasiliensis tree, most of which is sourced in Asia. Its popularity in higher-end bedding materials and mattresses owes to its more natural formulation, its great pressure relief, and its temperature regulation.
Latex brands tend to be slightly more expensive than their all-foam or innerspring competitors, but the feel and experience of these brands may be highly different depending on processes used to build the latex and materials used to complement them in the mattress.
- Is all Latex natural?
No. Some latex is completely synthetic and is formulated using petrochemicals that mimic the experience of natural latex. Some brands blend synthetic with natural to provide a more cost-effective latex product.
- How does Talalay compare to Dunlop processing?
Though Talalay and Dunlop both originate from the same sap, the methods used to turn that sap into foam result in vastly different feels.
Dunlop latex is poured into a mold, vulcanized in an oven and then thoroughly washed. The process and finished product tends to require fewer chemicals and feel more substantial and dense. Some argue that this process is “purer” than other methods.
Talalay, by comparison, requires a somewhat more intensive process that may involve a few chemicals, which is why Talalay is never certified organic. The resulting foam, however, is lighter, more consistent and springy compared to latex prepared using the Dunlop method.
- How is latex different from memory foam?
There are many brands that emphasize the different feels and advantages of latex over memory foam, but it really comes down to what you prefer. Latex offers great pressure relief, but you won’t get the tight, body-conforming hug you experience with memory materials. In addition, latex responds quickly to pressure so it eases repositioning, and the substance is naturally heat resistant.
- What if I’m allergic to latex?
Whether or not you should consider a latex bed if you are allergic is a discussion best conducted with your doctor, as only he or she can truly evaluate risk of allergic reaction. Those with minor allergies may not be affected if they never touch the latex directly, but those with more severe allergies may want to steer clear.
- Does latex last longer?
Yes, it does tend to last longer, especially more natural or organic brands, and this is often reflected in their longer warranties. Though they last longer in general, you should still usually replace a latex bed after 8-9 years.
A hybrid mattress uses a blend of two different materials to combine the advantages of each and offset any disadvantages the materials might have on their own. A hybrid is a “best of both worlds” experience, and these mattress often score really high among consumers for their attention to detail and diverse mix of features.
A hybrid may be a blend of two different foams (i.e. memory and latex) or a blend of foam with a brand new kind of material (elastic polymers and foam). Most commonly, bed companies produce a mix of foam and coils to provide the bounce and airflow associated with innerspring mattresses while delivering on the pressure relieving qualities associated with foams.
A hybrid may require a slightly larger investment than competitors that are built with only one type of bedding material, but they often provide substantial benefits that add considerably to their value. More modern hybrids are outfitted with fantastic new technology that can alleviate even the biggest concerns associated with traditional materials.
Worried about memory foam sleeping too hot? By pairing memory foam with a coil base, air flow beneath the coils can help heat disperse so sleep cool and pressure free all night long.
When people hear “airbed,” their first thought is those cheap guest beds you store in a closet and blow up with a bicycle pump when your guests arrive and deflate as soon as they leave, but this is only one segment of a vast market harnessing the power of air to provide a highly customized sleep.
Newer airbeds often contain a comfort layer that can provide foam pressure relief to the experience of an airbed, and some air beds are as tall as their traditional counterparts. While many airbeds on the market are designed for only occasional use (such as when guests arrive), but other choices are taking their place in the master bedrooms of many sleepers.
Let’s explain. Smart beds or those that offer customized support via remote control or smart phone rely on air bladders beneath the surface of their custom comfort layers to vary the firmness of the mattress to hit the sleeper’s individual sweet spots. Multiple air bladders can provide zoned support that maximizes body alignment and pressure relief simultaneously.
And you can put away that bicycle pump. Most modern or higher end airbeds can plug into the wall so that they can inflate without much effort, and (in some cases) deflate just as easily for convenient storage.
Choosing the right mattress size is a bit of an art. You have to consider the size of your bedroom, whether you will share the bed with a partner or pet, and finally strike a balance to find your ideal sleeping to living space ratio.
Twin: At 39 inches by 75 inches, a twin mattress works great for small spaces. It has enough space to fit one adult.
Twin XL: The twin XL mattress measures 39 inches by 80 inches making it 5 inches longer than a twin. It’s a must for someone tall and a good option for someone in a small space who wants a little more leg room.
Full: The full is the go-to choice for a starter mattress. It measures 54 inches by 75 inches, which gives a single sleeper room to stretch out. Most average-sized rooms and studio apartments can accommodate a full-sized bed.
Queen: A queen bed, 60 inches by 80 inches, is the most popular choice. It allows for two people to sleep comfortably. A bedroom should be at least 10 by 10 square feet to accommodate this size.
King: A king bed measures 76 inches by 80 inches and requires a larger room that is at least 10 x 12 square feet to allow room to walk around. This is the way to go for couples who share their bed with a larger pet.
Mattress height varies depending on which brand you choose, and more entry-level choices tend to be much thinner and simpler in their design that taller luxury brands that have more complicated comfort layers and support systems. If you have trouble getting in and out of bed, a mattress that is exceptionally tall may prove to be a problem.
Beware that price is not always an indication of quality, and some materials will naturally wear out faster than others, depending on how they are formulated and placed. In general, latex tends to last longer than poly foams, and tufting tends to endure natural wear and tear longer than adhesives. The longevity of coils will depend on their gauge and how they are attached to one another.
Choosing a mattress with a universal feel that can adapt to changing bodies or differing preferences is not only ideal for couples, it is also preferable for folks looking to prolong the usefulness of their mattress. If a bed can accommodate your changing size or sleep positions, this may enhance its long-term value.
All mattresses should contain a blend of comfort or softness and support (which tends to be more firm.) Beds with enhanced support systems may feel firmer than beds with enhanced comfort. Folks who are considerably heavier will often experience a brand as softer than sleepers who are much lighter because of the ability of their body to press through layers.
Sleep Position And Comfort Levels
In addition to choosing a mattress based on its construction and materials, take your sleep position and the mattress comfort level into consideration. These factors go hand-in-hand with which type of mattress you pick, and they will get you a step closer to finding the perfect mattress.
Comfort levels are basically a range of firmness. They tend to start with Extra Plush or Plush (on the softer side) and end with Firm, Extra Firm, or even Luxury Firm (on the firmer side). Some models just have one comfort level; others will offer different comfort options. Mattress firmness is often rated on a scale from one to 10, with 6.5 to 7 considered “average” firmness for a mattress.
Determining the right comfort level will come down to a combination of personal preference and usual sleep position(s). Here are some general rules of thumb:
Back sleepers. Back sleepers tend to do best with an average firmness (right around 6.5 or 7 on a 10-point scale). They could benefit from a range of comfort level labels as long as the mattress falls close to the middle in firmness.
Stomach sleepers. These sleepers need more support on their stomachs at night and will do best with a firmer-than-average mattress option.
Side sleepers. When side sleeping, there is a lot more pressure put on shoulders, hips, and knees. A softer or plusher option will provide extra relief and more contouring support.
Combo sleepers. This is really where personal preference comes into play. If you wake up primarily in one position, use that as a guide. But you may have to test out a few comfort levels before finding the right one for you.
What To Look For
Once you’ve decided to replace your mattress, what should one expect from a new mattress and what is the best mattress? Here’s a list of things to think about before handing over the credit card for a new purchase
Comfort And Cooling
It is a pain to wake up in pain! No one should have to wake up on a mattress feeling stiff or sore. Also, no one should wake up drenched in sweat or kicking all the covers off overnight because your mattress isn’t breathing well. Of course, there is a little bit of an adjustment period involved in testing out a new bed. Take advantage of those trial periods and try something else if it doesn’t feel right.
Support And Neutral Spine Alignment
It feels best when the head, neck, and spine are in neutral alignment, no matter the sleeping position. Without this natural alignment, sleepers may feel stiffness or aches when they wake up.
Lifespan, Longevity, And Durability
For most people, a mattress is a big investment. That means it’s important to think about how long one wants a new bed to last. Mattresses made with high-quality materials and good construction will easily outlast cheaper options, which means it won’t be necessary to buy a new mattress as frequently.
For those who sleep with a partner, motion transfer is extremely important. A mattress that handles motion transfer well will ensure that sleeping partners do not disturb one another when they move around at night. Those who want a mattress with little motion transfer should consider something with memory foam. This material is known for cutting down on motion transfer.
Different mattresses will provide varying degrees of edge support. A mattress with great edge support allows sleepers to rest close to the edge and maximize the surface area. Poor edge support will leave sleepers feeling like they are going to roll off the bed when they get close to the edge.
No one wants to feel like they broke the bank for a new bed. There are plenty of options out there, so it’s possible to find something that meets one’s needs without going into debt.
Before purchasing a new mattress, it’s a good idea to look at the company’s reputation and see how transparent they are about where their materials come from. (This is especially true for materials such as fire retardants. It’s also particularly important to do your research before buying a crib mattress for a new baby.) Also, whenever purchasing any type of mattress, make sure the mattress still has its tag on.
