Old is gold. The innerspring mattress is proof. It has stood the test of time despite the entry of newer technologies and a host of innovations in the mattress market. The mattress has been around since the 1930s, and it is still going strong. Even today, two-thirds of the mattresses bought are innerspring. Its earlier avatar, the box spring mattress was invented in the late nineteenth century but gave way to the innerspring after ruling the market for almost four decades. The new market entrants have also become popular over time. However, they have not been able to erode the innerspring market share.
Affordability and the tried-and-trusted factor account for the sustained popularity of the innerspring mattresses. This is backed by its suitability for a wide range of sleepers. The innerspring is ideal for stomach sleepers, individuals with back pain, and the high-BMI persons. They are good for persons who over-heat in sleep. This is because they are cooler in nature than the memory foam and latex mattresses.
What Is the Structure of An Innerspring Mattress?
An innerspring mattress is made of three layers:
The Foundation Layer
It is usually made of wool or other cushiony materials. Its basic functions are to provide support and a soft shock-absorbing foundation for the coil structure on its top.
The Coil Compartment
The coil compartment houses the grid of coils. They are usually aligned vertically as well as horizontally. The coil count and thickness vary from brand to brand. Usually, the coils are covered with titanium or steel coating. It gives them extra strength and bounce factor. They also offer better body contouring and pressure relief. These coils are known as Marshall Coils.
The coil compartment is bound with a perimeter coil along the border. It keeps the coils together and retains the shape and firmness. The edge of the grid is reinforced with additional springs or foam material. This prevents the sleeper from falling off the bed.
The Top Layer
This is the comfort layer. Usually, it is made of foam, latex or fiber. It offers the mattress its comfort and cushiony feel. Sometimes, an intermediate layer separates it from the coil compartment. It prevents the upholstery from getting deformed or sinking due to the pressure of the springs. This layer is made from a tough but padded material that possesses an insulating property.
Does the Coil Count Matter?
Yes and no.
Yes, because the number of springs is directly proportionate to the mattress’s strength, springiness, contour support, and comfort factors. As a general rule, denser coil grids produce better mattress quality.
However, this notion has changed over time. Innovations have made it possible to achieve better results with fewer coils, or even vice versa. Recent developments in the innerspring structure are:
- Lesser coils with thicker gauge
- Thinner coil gauge but denser structure
- Optimum coil count with better coil quality
So, it all depends on the type of coil.
A few points to ponder on the coil count debate:
- Research has confirmed that most of us sleep on our sides. Now, the side does not have the same profile as the back or front of the body. It is more contoured. Side-sleeping also produces most stress on the pressure points such as the neck, shoulders, and hips. Moreover, the spine is also differently aligned to the bed than in a flat sleeping position. And finally, side-sleeping puts lesser weight on the mattress. Hence, lesser coils with a thicker gauge work better with a majority of sleepers.
- As for the coil gauge, number 14 which is 1.63 mm thick is considered ideal for modern designs. It is important to note that the lesser the gauge, the thicker the coil thickness. A 12-gauge wire is thicker than a 14-gauge one.
- Coil count is optimized at 400 or less. Mattresses with increased coil count tend to be uncomfortably
- Mattress structures which opt for lesser coil count and thicker coils may be good to sleep on in a store. However, they can sag sooner than the other types of coils.
Ultimately, customization is the best policy. Buy a mattress that is best for your type of body and sleeping habit. Do consult the sales staff before taking a final decision.
What Are the Types of Coils Used in Innerspring Mattress?
Manufacturers make fancy claims with marketing jargon. However, it is important to note that basically, there are only four types of coil used in innerspring mattresses. Often times, competing brands use their coil from the same supplier!
Open Coil or Bonnell Coil
This type of coils was used in the buggy seats of during the 19th century. They are still the most common coils used in innerspring mattresses. Bonnell coils are hourglass shaped. They are joined with the neighboring coils by small wire spirals known as helical. Despite their sustained popularity, open coils are being slowly edged out by technologically superior options. Their main drawback is that they lose bounce soon. The mattress sinks from the center or gets deformed at the edges. Also, the springs become creaky and noisy over time.
This is the next generation of the Bonnell coil. It has a square top as opposed to the circular one of open coils. The coil shape is more cylindrical than the hourglass Bonnell. Although the most expensive coils, Offsets are preferred by discerning manufacturers for their durability.
These are also known as independent or Marshal coils.
Pocket coils are springs encased in individual fabric pockets. They are not naked as the other types of coils. This pocket or wrapping gives far superior contouring, weight distribution, and motion constraining properties to the bed. As a result, the mattress hugs the sleeper more closely. There is lesser sinking. And one partner does not get disturbed due to frequent movements of the other.
Pocket coils make good beds for those who move a lot during sleep, and overweight people.
As the name suggests, entire rows of coils are made from a continuous wire. They are attached to each other with helicals. Grids made of continuous coils have a lattice layout rather than the conventional rows. The continuous construction helps one coil to share the weight with the neighboring one. In this way, the weight is distributed evenly across the mattress surface. As a result, mattresses don’t deform easily.
Which Are the Top 5 Innerspring Mattresses?
Innerspring mattresses sell the most in the market. The onset of the online era has given a totally new dimension to sales lifecycles. Brands have now shifted from brick-and-mortar outlets to an online sale. Many have adopted the online-offline combined model. The online segment has become more aggressive in its marketing efforts. The reason is simple; the smaller stores have to compete with the giants like Amazon, Walmart, eBay, and a host of other major players. From coupons and vouchers to 0% APR, there is an ever-widening range of benefits offered to the shoppers.
This augurs well for the consumers. However, with a significant increase in brands, there can be a saturation of information and choices. This may lead to loss of focus and distraction from the core requirements. In many cases, marketers with lesser regard for good practices dole out extraordinary schemes. While they attract eyeballs, they may be misleading or plainly dishonest.
The shopper’s confusion and indecisiveness are increased by an interesting market trend. Even the reputed brands are offering so many variants and features. So one is unable to decide which ‘best brand’ to buy!
The market landscape is indeed cluttered, especially the online marketplace.
In due consideration of the market dilemma, a compilation of the top 5 brands is given below. This is to help the consumers make a choice that best suits their needs. However, it is not the final word. Readers may please note:

The Winkbeds Mattress Structure
It consists of three layers:
The foundation layer. As mentioned above, Winkbed’s unique foundation layer doubles up as the first coil zone. It has a soft foam base to act as a shock absorber. Moreover, it has a 7.5” high grid of pocketed coils. These are coil casings with a foam-wrap that boost the edge support. Hence, it is a foundation layer and also the first coil zone.
The middle layer. It is a 2.5” grid of micro coils that are encased in specialty foam. They increase the springiness and give the mattress extra support.
The comfort layer. This top layer is made of two different foams. The first is a 1.5” gel-infused polyfoam, and the second, a 1.5” polyfoam with the quality and feel of natural latex. The combination of the two top layers produces a luxurious and comfortable feeling that is distinct of Winkbeds innerspring beds.
Winkbeds Firmness Levels
The brand offers three firmness levels:
- Soft – measuring 4.5 on the firmness scale
- Luxury – 6.5 on this scale
- Firm – 7.5 on this scale
Apart from this, Winkbeds also offers the Winkebeds Plus firmness variant. It is meant for persons with 300+ lbs weight. This special category replaces the micro coil layer with a latex layer. This gives the required extra support for overweight people. The firmness level of Winkbeds Plus is 6.5.
Warranty, Free Trial, And More

Price of Winkbed Innerspring Mattress
Winkbeds Innerspring Queen mattress is priced $849 for twin XL, $1299 for Queen, and $1499 for King. The slightly pricey mattresses are value for money, considering the features and the double coil and top layers.
This luxury innerspring mattress comes from the thoroughbred Brentwood stable. The company has been manufacturing fine mattresses for over 30 years. Brentwood has an inborn liking for innerspring mattresses. Through in-house innovation and technological adoptation, it has constantly updated its spring mattresses. The Oceano is Brentwood’s yet another breakthrough in spring hybrids. It is an important update in spring-foam combination. It offers the pressure relieving goodness of spring technology with the next-level luxurious comfort of gel memory foam.
Although a hybrid, the Oceano gives the sleep quality of a thoroughbred.
The structure of the Oceano mattress
This structure is designed to deliver high performance. Rather than relying on the standard 3-layer design, the company has produced a thoughtful 5-layer construction. Its focus is on maximizing comfort and optimizing the springy bounce, so that the sleeper does not sink too deep or feel that the mattress is too hard to sleep on.
The structure incorporates two alternating layers of foam and coils, apart from the base and comfort layers.
The base layer
This mattress is significantly heavier than its peers. Against an average innerspring mattress weight of around 65 lbs., the Oceano weighs 113 lbs. Hence, a sturdy base is very important. This extra dense foam layer provides not only strength, but also stability to the bulk above it.
The first coil layer
This 8” layer is made of over 1000 individually wrapped coils in a typical Queen size Oceano mattress. These coils have varying firmness, depending on where they are placed. Its surface is divided into five zones. Three of them are in the main body of the mattress. They provide support to the head, shoulders, and legs. The remaining two zones are on the edges. They enhance the edge support.
The first foam layer
It is a 2” Airlux foam layer. It acts as an effective intermediate layer for the two coil layers placed beneath and above it. The foam is firm enough not to let the mattress sag over time. Yet, it is soft enough to be responsive to the body weight of the sleeper. The clever layer design makes Oceano an ideal mattress for heavy sleepers.
The second coil layer
This layer is made of 2.5” individually wrapped microcoils. They provide more responsive support than the bigger coils. They also inhibit motion transfer more effectively.
The second foam layer
This 2” gel memory foam layer improves the comfort and contouring factors. Being cooler than other foams, it also provides a cozier sleep.
The comfort layer
The .5” quilt layer is made of finest quality New Zealand wool. It acts an excellent heat regulating agent. Hence, it keeps the mattress cool during the hot months and warm in winters. The New Zealand wool gives exceptional comfort.
The smart structure design of Oceano unfolds the true essence of hybrid mattresses. it complements the bounce of the springs with the comfort of the foams.

The innerspring mattress has survived for almost eight decades. The mattress market is a jungle. As the saying goes, it is survival of the fittest. The innerspring mattresses have proved their fitness on the strength of their springs. To coin a catch-phrase, some springs die hard.
What has caused these mattresses to sustain for so long? It is the originality of the idea. The nature of a spring is to recoil under pressure and to bounce when the pressure is released. Putting this simple principle to creative use, the German genius Heinrich Westphal invented the innerspring mattress in 1871. The idea and its application are so brilliant that they have not lost their sheen even today.
