Innerspring mattresses have been tried and tested over decades and remain the most popular choice today. They feature a steel coil core support system padded on top with foam or fiber material. This provides you with a comfortable, flexible, and supportive surface that keeps you cooler than other types of beds, allows for natural body movement, and limits motion disturbance.
There are many types of innerspring mattresses – the quantity, design, and thickness (or gauge) of coils can vary a great deal. Plus, some are “hybrid” beds, which can be either topped with memory foam, latex, or even gel, and the depth and density of the layers can differ, too.
All of this variety can make choosing the right model difficult. But don’t let that put you off! We’ve reviewed the best innerspring mattress brands and compiled a guide on the different types of coil springs. Below are some of the top-rated models on the market at the moment. Take a look:
|Signature Sleep Contour||Independently encased steel coils and High Density foam||8"||1 Year||9.7/10|
|Signature Sleep Signature||Independently encased coils and Pillow Top||13"||1 Year||9.3/10|

How To Choose The Best Spring Mattress
Innerspring beds come in a variety of models. Below we will have a look at the main coil designs and their pros and cons, as well as why coil count and coil gauge are important factors to consider when buying a mattress.
Different Coil Types Comparison
There are different types of coil patterns and designs. The most commonly available contain four main types of coil types, which are usually advertised as follows:
Often considered the best type by customers, this design is also referred to as pocket, encased, wrapped, or Marshall coil. This type of bed consists of hundreds or even thousands of individual coil springs, each sitting in its own fabric pocket. As they are not attached to each other, the springs can move independently of each other.
This type of spring system conforms to your body, distributing your weight evenly and preventing pressure points that can cause back and shoulder pain. For this reason, pocket spring mattresses provide supreme support. The individual springs also prevent motion disturbance, as, if you move, your partner does not feel it on their side.
Due to these highly desirable features, pocket spring beds are usually the most expensive of all four types.
Open coils, also commonly called “the Bonnell,” is the oldest and most common type of spring system, and is often found in cheap innerspring mattresses. The open coil design consists of multiple springs, which are interconnected within a wire frame. A standard double open coil mattress usually contains about 300 springs.
This design usually provides a very firm support. They are often used in orthopedic mattresses for this reason. They are also lighter than pocket spring mattresses, making them easier to turn. Unlike the pocket spring, however, they can “dip” in the middle. Couples may notice movement from their partner, and roll-together can be an issue, too.
Mid- to high-priced
Offset coils are similar in structure to open coils, except each spring is hinged together by a helical wire on top. Like pocket coils, this design provides body contouring and better motion isolation.
However, they can be made firmer than a pocket coil, as the hinging effect allows more load-bearing on the springs. This type of bed is a good choice if you want a soft surface with a firm, supportive core.
Low- to mid-priced
As the name suggests, continuous coil, also known as Mira Coil, beds are made up of rows of coils, going from head to toe, using a single piece of wire. These are then attached with helical wires, forming an interconnected network.
This design can provide a durable and very firm and supportive mattress at a low cost. However, they do not conform to your body as pocket spring and offset coils do, and they can be noisy.
Coil Count Guide
The coil count is the number of coils (or springs) inside the mattress. This number can range from 200 in a twin to 1000 in queen size bed or 2000 in a high-quality, king size bed.
More coils indicate a better-quality mattress, as the more springs there are, the sturdier it will be. This means a more supportive as well as longer-lasting bed. It may not come as a surprise, then, that the higher the number of coils, the higher the cost. Anything under 300 is generally considered poor quality.
However, do bear in mind that the coil count isn’t the only thing that matters in terms of quality. The coil gauge is just also important.
The “gauge” of the coil simply refers to the thickness of the metal wire used to form the coil. Numbers commonly range from 12 and 15, with half gauges in between, but they can sometimes go up to 18.
While it may sound confusing, lower coil gauges have thicker wires and create a firmer spring, while higher coil gauges have thinner wires and provide a softer spring.
In other words, if you are looking for a very firm and supportive bed, it is best to go for a 12-coil gauge. If you prefer a bouncy, soft mattress, however, go for 13.5 and above.
You should always compare the number of coils to the gauge of the coils when choosing your bed. This is because a mattress with stronger wires but fewer coils can offer the same or even better quality as one with more but thinner coils.
Advantages Of Owning A Coil Spring Mattress
Limited conforming ability
Innerspring beds do not mold so much to the shape of your body as some other non-innerspring types of mattresses. This means that there is more airflow around you, which stops you from getting uncomfortably hot at night. You can also move easily on this surface, meaning that changing positions and getting up doesn’t require effort.
Innerspring beds are sold in a wide variety of models from a large selection of brands. This means that there is likely to be one to suit your needs as well as your budget. Whether you want firm or soft, large or small, and with or without a memory foam or latex topper, you are sure to be able to find the right model for you.
As there are so many models on the market, there will always be an affordable choice if you are on a budget. There are also many models that are a great deal and still good-quality, so you don’t have to give up on your dream of a great night’s sleep.
Who Should Buy An Innerspring Mattress?
Anyone can benefit from owning an innerspring bed. In fact, some argue that they are good for your health because the springs hold up your body to provide the right support and alignment, as well as prevent poor blood circulation.
Spring beds are an excellent option for larger-set people, according to Web MD, as the firm support makes them easier to get in and out of. Innerspring mattresses are also the top choice for people with back pain, especially firmer versions, given the good support they can offer.
Depending on what position you sleep in, there are certain types of innerspring mattresses that can suit you. For stomach and back sleepers, it is recommended that you have a strong core support system to maintain optimal alignment of the spine. Therefore, pocket springs, which help spread your weight evenly on the bed, are a good choice if you fall in this category.
Side sleepers can do well with a hybrid innerspring mattress. You still need support from a coil core, but a top layer can provide more a comfortable, pressure-relieving surface.
Top Rated Innerspring Mattress Reviews
1. Signature Sleep Contour 8 Inch
Available in: Twin to King
This model from Signature Sleep offers luxury features and maximum comfort at a very affordable price.
The Contour 8 reversible mattress features a 7-inch coil support structure, each made from 15-gauge steel. These coils are independently encased to ensure no motion disturbance interrupts your soundless sleep.
As for the surface, the top and bottom of the bed are covered in a 1.6-inch layer of high-density foam padding. This adjusts to your body, distributing your weight evenly on the surface, giving an embracing feel. On top of this, it has a soft, breathable knit fabric mattress cover.
The control of the individually wrapped springs and comfort of the padded top layer make this bed that will keep you sleeping tight throughout the night.
While a small minority of customers found this bed less durable than they would have liked, the majority of customers are extremely satisfied, rating it as highly comfortable and low-cost.
The high-gauge steel makes this a fairly soft bed, so if you prefer a firmer surface, this model probably isn’t the top choice for you.
2. Signature Sleep Signature 13 Inch
Available in: Full, Queen, and King
Here is yet another model from Signature Sleep with a very inexpensive price tag given the high-end quality it offers.
The core of this mattress is made up of 10 inches of independently encased coils with a 13.5 gauge. The individually wrapped coils provide equal weight distribution, contouring to your body and giving you a more restful night’s sleep. The gauge of the coils makes this a medium-firm mattress, but the plush 1.6-inch pillow top, containing a “3 zone foam” layer, offers maximum comfort. This means you will never be lying directly on the coils, and you can say goodbye to those restless nights’ sleep.
On top of all that, the mattress material itself is made of bamboo, which provides excellent moisture absorbency and breathability, creating a dry, restful sleep.
This bed is large, at 13”, and is only available in the larger sizes, so it is a model that is usually used by adults.
Some reviewers found this mattress firmer than they had expected – this is due to the 13.5 gauge, which does not make it one of the softest surfaces, despite the pillow top and foam layer features. So, if you are looking for a soft mattress, this isn’t the one for you. Despite this, most customers comment that this bed exceeds their expectations given its low price.
3. Zinus Sleep Master Ultima Comfort 8 Inch
Available in: Twin – King
The Zinus Sleep Master Ultima Comfort 8 Inch mattress consists of hundreds of “iCoil” pocketed springs. These minimize motion transfer, meaning you can get undisturbed sleep regardless of your partner’s movements. They also offer great support by maintaining correct alignment of your spine.
On top of this spring core comes a layer of Comfort Foam and a Fiber Quilted Cover. These help to relieve pressure points by conforming to your body, plus they add a soft layer atop all those coils so you can lie down and feel supported yet comfortable.
Many people who own this product note that it is above average for durability, claiming it does not dip or sag over time. Some reviewers found it too firm, however, which is likely to be down to the pocket springs and a heavy coil gauge. Therefore, this model is a good choice if you prefer a firm surface. It is could also be a good option for back or front sleepers and for those who suffer from back pain, who are in need of a firm support.
4. LinenSpa 8″ Memory Foam and Innerspring Hybrid
Available in: Twin – King
The LinenSpa 8” Hybrid mattress offers the support and durability you get from a traditional innerspring core along with pressure-point relief from a 1.5-inch memory foam layer. This layer, which is quilted in the knit cover, conforms to the curves of your body, helping to distribute your weight evenly and give you a comfortable and supportive surface on which to sleep.
What’s more, underneath the memory foam is another foam layer and a felt pad, which adds an extra level of comfort as well as durability. Beneath this, the springs still provide bounce and breathability. This hybrid mattress does give the best of both worlds.
Many customers buy this for themselves as well as their children. The majority of customers highly rate the soft and comfortable top layer of this bed, saying it is almost too comfortable. So, if you don’t want to get out of bed, this mattress could be a good choice for you!
5. LinenSpa 6″ Innerspring
Available in: Twin – California King
This LinenSpa 6” mattress contains heavy gauge tempered steel coils, which makes it a very firm, supportive surface. For this reason, many reviewers recommend it if you suffer from back pain. It contains a quilted fabric cover, foam layer, and felt pad to provide a comfortable, cushioned surface. At just 6 inches deep, it is a “low-profile” bed, which makes it an excellent choice for children, or for an apartment or guest bedroom.
This spring mattress has a fire resistant barrier that’s been tested to ensure it complies with safety standards so that you can rest easy.
As with the LinenSpa 8” Hybrid, some reviewers found this mattress too firm for them due to the heavy gauge coils, so make sure you ask yourself what level of firmness you want before purchasing.
However, the majority of people are satisfied after purchasing this bed due to the high levels of comfort it provides at such a low price. This makes it a great choice if you want maximum comfort at a minimum cost. It is also a particularly popular choice for children, given its small size.
Innerspring mattresses are the traditional choice and are still widely popular today. They provide support, durability, and breathability. There are many factors to consider when choosing a mattress, including spring design, coil count, and coil gauge. These all contribute to how durable, soft, or firm it is.

Hopefully, our how-to-buy guide has cleared up some of the mattress-related mysteries that were on your mind before you read this article.
As for the models we reviewed, we rated the reversible Signature Sleep Contour 8 Inch mattress at number one for a few reasons.

When I’m not learning about sleep, you can find me watching “the big game” with my friends. I absolutely love sports and have grown to follow the rest aspect in athletes. Modern technology allows us to track athletes sleep and rest, which in turn helps predict their performance.
I hope that everyone that finds our site takes a new approach to sleep. The world needs to stop thinking about it as something “we just do”, but rather something that allows us “to do everyday.”
Cheers to having the best sleep of your life!
