Best Innerspring Mattress: Reviews and Buyer’s Guide
Innerspring mattresses, or coil beds as you might also know them, have been around for quite a while. The first innerspring mattress was manufactured in 1871, 14 years after the steel coil spring was invented. In later years, the box spring was invented to enhance the comfort of innerspring beds, and an industry was born.
Innerspring mattresses are still widely available today and quite popular, although their construction has evolved to give the customer a more comfortable sleep experience. Now it’s more common to find innerspring mattresses with individually-wrapped coils, back support enhancements built into the layers, or foam components for added comfort.
Today we’ll go over a few of our favorite innerspring mattresses along with what you should expect from an innerspring, the benefits of using one, and how they compare to other mattress types.

Innerspring mattresses are popular because of their even surface, responsiveness, and strong support system in the form of coils. Innerspring mattresses are also known to be more cooling than foam or latex because the coils allow air to flow through more naturally than other materials.
If you’re considering an innerspring as your best mattress of 2019, take into account your sleeping position, weight, and whether or not you sleep with a partner. These factors along with a few others will determine if an innerspring is right for you.
We paid special attention to mattresses with a strong support core built into the base in the form of steel coils and a soft comfort layer— usually made with latex, foam, or polyfoam— to offset any rigidity from the coils.
1. The Saatva Mattress
The Saatva mattress is first on our list thanks to its substantial coil support and Spinal Zone Technology. The quilted Euro pillow top is treated with the antimicrobial Guardin®, which inhibits the growth of bacteria, mold, and mildew.
The bed itself is encased in a Dual Perimeter edge support system made of high-density foam. This support system deters sag, prolongs the life of the mattress, and helps you feel like you won’t fall off.
This mattress actually has two layers of support coils— the first has 416 individually wrapped 14.5-gauge comfort coils designed to respond and contour to your body. Between this layer and the base layer of steel coils lies the Lumbar Zone technology.
Two support enhancements act as the pressure relief system by using a high-quality foam layer and an active support system to further bolster your back and lower spine. Finally, the steel coil base made of 884 coils can protect your mattress from sagging over time.
The dual-coil system allows plenty of airflow as well as limited motion transfer. You can purchase the Saatva on their website, and it comes with free white glove delivery and a 120-night sleep trial.
- Steel coils and individually-wrapped coils allow for maximum breathability, bounce, and support.
- Lumbar Zone technology provides additional support to your lower back and spine.
- Three firmness options: Plush Soft, Luxury Firm (the most popular), and Firm. The Luxury Firm is a 5-7 on the firmness scale from 1-10, making it a solid medium mattress.
2. WinkBeds The WinkBed
WinkBeds makes three different mattresses, but the original WinkBed is our favorite because of its top-notch features.
With this bed, you can choose from four different firmness levels ranging from softer (4.5) to Plus, or extremely firm (8). Their bestselling choice is the Luxury Firm, a solid 6.5 or medium— which is usually a comfortable firmness for most sleeping positions.
The top comfort layer is a Euro-pillow top made of gel-infused hyper-soft foam. The gel acts as a cooling agent to pull heat away from your body, preventing heat from getting trapped under you as you sleep.
Underneath the comfort layer sits individually wrapped coils to contour to your body, pushing back on areas needing more support and cushioning the rest. The wrapped coils isolate movement, so you shouldn’t feel your partner shifting around all night.
Extra-Edge™ reinforcements encase the mattress and keep the surface even, so you can sleep in a healthy position all night.
- Individually-wrapped coil support system provides targeted back support and pressure relief where you need it.
- Euro-pillow top made of gel-infused foam keeps you cool and comfortable.
- Comes with free shipping, free returns, and a lifetime warranty.
3. Avocado Mattress
The Avocado Green Mattress is one of the most environmentally friendly mattresses on our list. Not only is it made using green manufacturing processes, but it’s comprised of GOTS organic certified materials, earning it a Greenguard Gold Certification.
Avocado’s mattress is a hybrid, meaning it’s made with 50% foam and 50% innerspring coils.
Because the Avocado mattress uses latex foam as their comfort layer, it’s a little bit pricier than other models— party due to latex’s enhanced durability. Latex beds last up to 15 years on average, or 5 years longer than memory foam mattresses and 7 years longer than innersprings.
As far as feel goes, the Avocado is rated as medium-firm, which is good for back or stomach sleepers. If you’d prefer something a bit plusher, Avocado offers a 2-inch pillow-top option for an additional cost.
The Avocado mattress combines natural cushioning with an internal pressure-point system for extensive back support. The support core consists of 1,414 steel coils arranged in 5 ergonomic zones to keep your back and spine aligned properly, distribute weight evenly, and alleviate pressure points.
- Plant-based latex foam is eco-friendly and GOTS certified
- Steel coil springs at the base prevent motion transfer and help relieve pressure on your back and spine.
- Comes with free shipping, free returns, and a generous 1-year sleep trial.
4. Helix Midnight
Helix makes nine different mattresses to suit a wide variety of sleep preferences, and our favorite is the Helix Midnight. It has a perfect medium feel, memory foam layers for pressure relief, and wrapped coils to cradle your body and extend the life of the mattress.
One concern when using foam in a mattress is the potential for heat retention. Companies using foam in their mattresses have started using open-cell technology or low-density foams to promote airflow. The Helix Midnight uses foam with their Soft Touch Design to increase airflow and prevent heat-retention.
Along with soft memory foam, Helix uses its proprietary Dynamic Foam for additional pressure relief and contouring. The wrapped coils in the core support layer round out the abundant support offered by this mattress.
- Medium mattress is perfect for side and combo sleepers.
- Soft Touch Foam combined with Dynamic Foam relieves pressure and cradles your body.
- Wrapped coils and dense foam in the base deter sag and keep the mattress surface even.
5. Brooklyn Bedding Bloom
Brooklyn Bedding’s latex hybrid bed comes with three firmness options— soft, medium, and firm— so you can pick the one most compatible with your sleep style.
The Bloom uses Talalay latex as its comfort layer. Typically, there are two types of latex used in mattresses— Dunlop and Talalay. There are a few differences between them, but the main difference is springiness. Talalay is usually bouncy, whereas Dunlop is springy.
The 8” base consists of 1,189 individually encased Quantum™ Edge coils which relieve pressure and decrease motion transfer. A 1” high-density foam base reinforces the coils and as they compress, decreasing the risk of bursting or sagging.
Brooklyn Bedding Highlights
- Comfort layer made of Talalay latex is buoyant and muscle-relieving.
- 8” base of individually encased coils help to minimize motion transfer and gives the bed bounce and durability.
- Comes with free shipping, free returns, and a 120-night sleep trial.
6. Simmons Beautyrest Black
The Simmons Beautyrest Black mattress is their most cooling model, utilizing BlackIce™ 4.0 technology to regulate your body temperature. The mattress also uses three different comfort foams for ultimate pressure relief, including a gel-infused foam for extra cooling.
The pocketed, braided nano-coils at the base absorb energy, reduce motion, and provide additional durability, meaning you can sleep undisturbed. Many customer reviews noted the bed helped them sleep more soundly.
The Beautyrest Black rates as a true medium on the firmness scale, making it great for most sleeping positions.
- 2,000 braided nano-coils in the base create bounce, stability, and lift.
- Plush comfort form, medium comfort foam, and RightTemp™ comfort foam combine to give you plenty of pressure relief.
- BlackIce™ technology works with the gel-infused foam to keep you cool all night.
7. The Aviya Mattress
The Aviya Mattress is another hybrid in our lineup made with 3” of foam in the top comfort layer along with wrapped steel coils in the base.
The top layers of foam are split into three different levels and serve three different purposes. The topmost layer is breathable comfort foam, responding to your body’s curves and cushioning any painful spots. The second layer, a high-density foam, prevents sagging and stability, while the third layer of foam enhances lumbar support for all pressure points.
In addition to the bed’s pocketed coil system, Aviya reinforces the middle of the mattress with more durable coils to prevent sinkage, and the entire bed is encased in high-density foam.
- 3” foam in the top layer combined with a high-density foam encasement provides maximum pressure relief and stability.
- Individually wrapped coils in the base limit motion transfer and allow for increased airflow.
- Free shipping, free returns, and a 100-night sleep trial.
Innerspring vs. Hybrid Mattresses
We’ve discussed both hybrids and innersprings in this article, but what’s the true difference between the two? While innerspring mattresses are currently a more popular option, hybrids are becoming more sought-after thanks to their unique combination of foam and innersprings.
Innerspring mattresses are named as such for their support core. Considered the “heart” of the mattress, the support core consists of metal springs or coils spaced evenly apart. They give the bed its familiar “bouncy” feel and the natural airflow between springs makes for a cooler mattress.
While innersprings make up about ⅔ of sales in the mattress industry, they are also associated with the most customer dissatisfaction. Some common complaints associated with innerspring mattresses include sagging, too much motion transfer, and a short lifespan. The companies on our list have begun to address these issues by adding additional comfort and support layers as well as “converting” their innerspring beds to hybrids.
By definition, a true hybrid bed must have at least two inches of foam and/or latex in the comfort layer— anything less than that makes it an innerspring. Most hybrids use more than two inches of foam as the top layer, and many of them reinforce other layers with foam as well.
A frequent issue associated with foam is it sleeps too hot. Foam mattress companies have already begun to tackle this problem by using open-cell or cooling technologies such as gel, copper, or graphite. A hybrid conveniently combines the airflow of innerspring mattresses with the softness of foam, so you get the best of both worlds (without the worst)!
Different Coil Types
Not all coils are created equal. Let’s go over the different types you might find in the support cores of your favorite mattresses.
Bonnell coils are the grandfather of all other coils— they are probably the type sitting in your childhood mattress. They are the cheapest and most widely available coil, often used in hotel mattresses due to their ability to withstand lots of use over time.
Offset coils are made of tempered steel and, like Bonnell oils, they are shaped like an hourglass. Unlike Bonnell coils, however, they are hinged together for extra durability.
There’s actually two variations of offset coils: double offset coils, which are straightened at the top and bottom for more support, and free arm offset coils, which are not joined together. No matter the type of offset coil, mattresses made with them are usually more expensive since this coil type is long-lasting.
Continuous Wire Coils
Continuous wire coils are not really shaped like a “coil,” but they are known for being just as durable as offset coils. While the springs are joined together, they do not contour to the body as well as offset coils or Bonnell coils, so this coil type can be less supportive and comfortable than others.
Individually Wrapped Coils (Marshall Coils)
Wrapped coils, also known as Marshall coils or pocketed coils, are encased in fabric for better motion transfer. They are connected to each other with hot glue, unlike other coil types which are hooked together using wires or rings (known as “helicals”).
The cloth encasement also gives the coils better contouring ability and insulation, so not only are they long-lasting, but they support your spine and back better than other coil types. As a result, mattresses using pocketed coils are on the pricier end.
As their name suggests, microcoils are tiny and they work much like pocketed coils do by limiting motion transfer. They are sometimes found in the comfort layer of a mattress, which is a bit unusual for coils.
A microcoil is typically between 1-3 inches long, wrapped in fabric or thin foam, and made of a thin wire with a high gauge. You may find microcoils most often in hybrid beds, but they can be used in innerspring, latex, or foam beds as well.
What makes microcoils so special? They are very good at isolating motion and they create excellent airflow— think of them as an upgraded (albeit much smaller) coil.
Other Elements to Consider
Other coil characteristics can affect the feel and cost of an innerspring. Let’s break down each of these in more detail.
Are more coils better? Not always! Sometimes a higher coil count is just a marketing tactic to make you think a bed has all the bells and whistles. The average coil count of an innerspring mattress falls between 500 to 1,000– a coil count above 1,000 hasn’t yet been proven to increase comfort, support, or durability.
Pitch refers to the angle of the coils and wires in relation to the mattress surface. The pitch determines how soft or hard a mattress feels.
Gauge refers to the thickness of the coils. The higher the gauge, the thinner the wire, and the lower the gauge, the thicker the wire. One is not necessarily better than the other, but they do serve different purposes. High gauge coils are quite springy and sometimes used in comfort layers (microcoils are a good example of a high gauge coil).
Lower gauge coils are more durable and firmer, so they are often placed in the support core layer at the base.
How Sleeping Position Affects the Kind of Mattress You Should Buy
Side sleepers will be on the lookout for a bed with adequate cushioning in the comfort layer as well as a sturdy support system to keep their back and spine neutral. No matter the mattress type, a medium feel is usually the perfect fit for side sleepers.
|Mattress Type||Pros for Side Sleepers||Cons for Side Sleepers|
|Innerspring||Sleeps cool, good edge support||Typically quite firm, sagging, limited pressure relief|
|Hybrid||Close conforming, sleeps cool, good motion isolation||May be prone to sagging, may be too bouncy|
|Memory Foam||Close conforming, soft but supportive, good motion isolation||Can sleep hot, sometimes sags easily, minimal edge support|
|Latex||Supportive, pressure-relief, durable||Sometimes not as soft as memory foam or hybrids|
Sleep Junkie doesn’t recommend stomach sleeping simply because it puts you at a higher risk for misalignment and back pain. However, if you’re in the habit of sleeping this way, choosing a very supportive mattress and the right pillow can make a big difference. Stomach sleepers are usually most comfortable on a medium-firm to firm mattress.
|Mattress Type||Pros for Stomach Sleepers||Cons for Stomach Sleepers|
|Innerspring||Typically more firm, bouncy, supportive||Minimal pressure relief, not close-conforming, can sag|
|Hybrid||Close conforming, pressure relief, strong edge support, responsive||Some models may not be supportive enough, can sleep hot|
|Memory Foam||Close conforming, pressure relief, motion isolation||Sleep hot, some sagging, may be too soft, may not be supportive enough|
|Latex||Close conforming, pressure relief, motion isolation||May not be supportive enough for some stomach sleepers|
Back sleepers need a supportive mattress without too much give so they don’t feel like they’re sinking. They will need a mattress with an even surface that doesn’t sag. A medium to medium-firm mattress is typically best if you sleep this way.
|Mattress Type||Pros for Back Sleepers||Cons for Back Sleepers|
|Innerspring||Even surface, supportive, sleeps cool||Prone to some sagging, may not be cushioned enough|
|Hybrid||Conforming, pressure relief||May sleep hot, prone to some sagging|
|Memory Foam||Pressure relief, soft, close conforming||Prone to more sag, may not be supportive enough|
|Latex||Close conforming, pressure relief, motion isolation||Some sagging, may be too bouncy|
How Do Innersprings Compare to Other Mattress Types?
|Mattress Type||Pros||Cons||Average Cost (Queen)|
|Innerspring||Good air circulation|
Often the most budget-friendly option
|Limited contouring ability|
Can sag over time
|Hybrid||All the benefits of foam and innersprings!||More expensive|
Heavy, hard to move
|Memory Foam||Soft and pressure-relieving|
|Can sleep hot|
Can have an off-gassing odor
Bouncier than memory foam
Average Lifespan and Warranties
An innerspring’s average lifespan is around 5.5 years, depending on the coil gauge, coil composition, coil type, and whether or not there are foam or latex layers.
Low-gauge coils or coils made of tempered steel tend to last longer than higher-gauge coils. Pocketed coils have a lower lifespan than other types, and Bonnell and offset coils have the longest.
Always look at a company’s warranty before purchasing— since innerspring mattresses have the shortest lifespan of any other mattress type, you will need to know what’s covered in that warranty and how long you can rely on it. The industry standard is a 10-year warranty (for all mattress types), with many companies now offering 20 years or more.
If the warranty is longer than 10 years, usually it’s prorated, meaning after the first ten years, the owner has to pay a certain percentage of the original mattress cost to get it repaired.
Defects usually covered by warranties include sagging of more than 1”, burst or deformed coils, or deformities in the mattress cover not caused by the owner.
