Innerspring mattresses have been around for many years now. Most people do have a basic idea about what they are. Memory foams and latex mattresses joined the party later, but innersprings are like their early ancestors in the mattress field. Innerspring cushioning first came to scene back in 1870 when Berliner Heinrich Westphal brought this concept to bedding. His design was a revolution as it featured a sleep surface that was firm and its rows were insulated with coils made of metal. These coils were able to provide support and withstand the compression. 60 years after that, the design was patented in the US and has dominated the mattress industry for quite some time.

You know that we want to guide you to pick the best innerspring mattress within your budget, so we truly suggest you read our guide firstly, but if you’re in hurry, you can jump to our top 5 choices directly.

Innerspring Mattress Buying Guide

Recently, some other models have joined the mattress market including latex, memory foam, airbeds, and hybrids. Nevertheless, innerspring still comprise two-thirds of the overall sales of the industry according to recent research. Most people still prefer innersprings over other types of mattresses because innersprings are relatively cheap and are readily available at different sales points both in-store and online.

Innersprings are also best suited for stomach sleepers. Moreover, people who weigh more than 230lbs. and those who have some backache issues also prefer coiled mattresses. These mattresses even sleep cool as compared to polyfoam and latex. On the other hand, there are some criticisms associated with coiled mattresses too. Innersprings are prone to premature sagging, don’t have much lifespan and they don’t offer motion isolation.

Innerspring Mattress types

There are different kinds of innersprings that you can find on the market. Some of them have traditional design and construction while others are hybrid. The primary design and structure remain the same across all models. The support core comprises four different types of coils which are listed as follows:

  • Bonnell coils

These innerspring mattress coils have an hourglass shape, and the middle of the coil is thinner as compared to edges. These coils compress with soft pressure and are the cheapest regarding price.

For this reason, they also offer low durability. There are different firmness levels that you can pick because they come in different wire gauges. Nevertheless, the firm versions are better than the soft ones.

 The mattresses with Bonnell coils are best for dorms, guest rooms, and kids’ room. You don’t need to spend much on these beds. 
  • Continuous Coils

The innerspring mattress with continuous coils is another simple option which is inexpensive as well. A continuous wire is used in the development of these coils, and they are aligned in rows. The rows are linked with the help of helical.

This coil system also offers an excellent support system which is firm. Continuous coiled innersprings work well with thick comfort layers while the helical can prevent motion transfer. The only disadvantage here is the interlinked neighboring coils don’t provide much body contouring.

 If you want to get an inexpensive mattress and need improved support in the middle due to lower backaches, then continuous coil innerspring is the best option for you. 
  •  Offset Coils

Offset coils are better than their Bonnell and continuous counterparts. These coils work with the help of a shaped wire that creates a hinged effect while joining the next coil. If you increase the pressure, then the base layer comes into action.

Offset coils come in different versions including top & bottom hinged, double and single-sided extension, double offset and free-arm. It is the second-costliest coil type and is suitable for a differential mattress construction.

 If you are on a budget, then offset coils might not be a good option for you. If you sleep with your partner, then it shares the load better as compared to the pocketed innersprings. Offset coil innersprings offer low firmness for support as well. 
  • Pocketed Coils

Innersprings with pocketed coils provide the best response rate if you are looking for this attribute specifically. These coils produce a plusher firmness on the first compression, and it increases with a deep compression. In most cases, the pocketed coil innersprings are imported versions. Furthermore, the North American manufacturers offer better quality than their Asian counterparts as well.

Pocketed coils score very high when it comes to motion isolation. This mattress is an ideal option for you if you share your bed with your significant other. As they come with individual wrapping, the pocketed coil innersprings also offer better body contouring as compared to other coiled mattresses.

 If you need to make good use of your investment and expect high durability from your innerspring mattress, then you should go for pocketed coils. If you weigh over 230lbs. then this mattress is a good option for you. The pocketed coil innersprings are also a good option for couples because it reduces motion transferability. 
  • Summary
Coil Type Price Shape Joiner Coil Gauge Coil Count
Bonnell $$ Hourglass (rounded) Low-gauge wire & helical Low – High 300 – 600
Offset $$$ Hourglass (straightened ends) Helical Low – Medium 600 – 2,000
Continuous $$ Straight line Helical Medium-High 400 – 800
Pocketed $$$$ Spiral (encased with cloth) Glue (hot-melt) High 800 – 1,200

Coil count

A common question that appears is what the ideal coil count of a good quality innerspring is?  It is a noteworthy point since the number of coils can influence the overall support and comfort that innerspring offer. For more than five decades the standard coil count has been 800 in a queen mattress.

Nevertheless, some manufacturers claim and offer significantly higher coil count than 800 too. But,  a higher number of coil counts don’t guarantee quality either . Therefore, you have to check the facts behind the claims yourself practically. In most cases, a full-size mattress comes with 300, a queen comes with 400, and a king comes with 480 coil count on average.

Coil Gauge

In addition to coil count, coil gauge also makes plenty of difference. Coil gauge refers to the thickness level of the coils used in an innerspring mattress. The coils that have a higher gauge provide a softer feel. On the other hand, the low gauged coils have a much longer lifespan as compared to high-gauged coils.

 People who weigh over 230lbs. should look for low-gauged coils  because it will provide improved support and pushback. It is better to see for coil gauge that ranges between 12 and 15. If you like a soft feel, then go for a range that is close to 15. For more firmness, you should aim for a gauge close to 12.

The comfort layer of innersprings

The layer above the spring support core is the comfort layer of the mattress. Usually, there are one or two layers involved in this segment of an innerspring mattress. The comfort layer has a low density as compared to the support core. This layer might be made of memory foam or latex.

Zoning

Zoning means that a single innerspring mattress has different firmness levels in different regions. It enables the mattress to contour according to your body type. There are three different regions of your body type, including your lumbar, shoulder and hip area. The innerspring that comes with zoning offers a softer firmness in the shoulder and hip area while it provides an increased stiffness in the lumbar region for additional support.

The Feel

Some of you might feel the innersprings a little firmer as compared to the latex or polyfoam. Therefore, you might experience less pressure relief and contouring in this case. The innersprings off excellent edge support where you mostly sit due to the coils system right up to the edges.

These innersprings offer much better bounce as compared to latex and memory foam as well but they are not good regarding noise and motion isolation. However, the high bounce of innersprings makes them better for sex. Furthermore, innersprings don’t retain as much hear as compared to memory foam or latex and sleep cool.

Lifespan

The lifespan of an innerspring can vary and based on different factors. Coil count, gauge, and composition are the most significant ones. The low gauges coils are durable as compared to high-gauges coils. The tempered steel coils are far more long-lasting than a non-tempered variant.

Therefore, the pocketed coils that are made of non-tempered steel and high gauging are least durable of all innerspring mattresses. The continuous coils are made for high compression but they medium gauging.

Offset and Bonnell coils are usually made of tempered steel and have low to medium gauging which means that they offer the best durability. However, innersprings steel has the least lifespan among all the options when compared with other types of mattresses.

Innerspring Average Lifespan

The Cost

The innersprings are the cheapest options among the mattresses. The prices of premium quality models range from $1400 to over $2400. On the other hand, an inferior quality innerspring will only cost you around $200 as well.
