A Brief Overview of King Koil

King Koil is a firm that has been in the game since 1898. As you can see, it has been around longer than most of the names that you come across in the market daily. Known initially as US Bedding, the company gradually transformed from producing innerspring mattresses to include foam units in their product line.

Most of the manufacturer’s units are customizable to suit their customers’ unique needs in terms of support and comfort.

One thing that makes King Koil stand out from other brands is that the manufacturing process makes use of the advice from the International Chiropractors Association (ICA) to ensure that all the units have proper spine alignment.

This endorsement is crucial as you are assured of acquiring a product that would not bring about significant complications to your spine and back.

Let us now look at the specific qualities of the King Koil mattresses.

1. Construction

The main determinant of a mattress’s quality is how it was made. With King Koil, the construction of their units involves different components, including fibers, coils, and latex. This combination should give you a hint that you are investing in a high-quality unit that is well-made to provide you with a memorable sleeping experience.

King Koil mattresses are divided into five exclusive collections, and the units could either be innerspring, foam, or hybrid models. Let’s look at each collection individually.

The World Edition Collection

This is a collection of innerspring mattresses, and they are:

The Siena Firm

This unit features a polyfoam comfort layer followed by a support core made of pocketed coils. The base layer is also made of polyfoam and contributes to the mattress’s overall stability.

As for the cover, it is quilted with a gel foam infusion to allow you to sleep cool.

The Sidney Firm

Like the Siena Firm unit, this one also starts with a quilted cover infused with gel foam. Next is a polyfoam comfort layer, which is followed by a support core made of pocketed coils.

The two layers are reinforced with a polyfoam base layer for the overall stability of the unit.

The Sydney Euro Top and The Monaco Plush

We have included these two models together due to their similarity in construction, from the quilted cover that is gel foam infused to the polyfoam comfort system for a good night’s sleep. This is followed by a pocketed coil support core, and the polyfoam base layer supports the entire unit.

The Monaco Euro Top

With this model, you will note some slight differences from the ones we checked out above. First, the polyfoam comfort layer features an extra lumbar support bottom. The support core is gel memory foam-infused at the center to equip the unit with a self-cooling quality.

The World Luxury Collection

This collection comprises six mattresses whereby the Kingsley units are innerspring models while the Montego units are considered hybrids.

Here they are:

Kingsley Firm

This model features a cover whose construction involves a combination of wool and silk in addition to the gel foam infusion. Then, the support core comprises of a polyfoam base layer and foam-encased pocketed coils.

Let’s not forget the comfort layer that is made of memory foam and polyfoam layers.

Kingsley Plush

This model’s features are similar to the Kingsley Firm, only that this unit is plushier and is softer to the touch.

Kingsley Euro Top

This unit stands apart from the above two models with a comfort layer made of memory foam, which has two insert layers of memory foam.

The Montego Luxury Firm

The cover of this model is a silk-wool blend and is gel foam infused. Then, the comfort layer comprises memory foam, polyfoam, and gel memory layers.

As for the support core, it features pocketed coils encased in foam.

The Montego Luxury Plush and Pillow Top

We noted a lot of similarities in how the above two models were made. First, the memory foam layer comprises gel memory foam and polyfoam layers. The next section is the support core, which features pocketed coils encased in foam.

The cover, like the other models, has a silk-wool blend to give them a soft feel.

World Extended Life Collection

This is collection features two hybrid mattresses, namely Athens Firm and Athens Plush.

Athens Firm

The first model features a comfort system that comprises a Talalay latex layer reinforced with two layers of high-density polyfoam. The fabric cover is gel-infused, while the support core includes foam-encased pocketed coils.

Athens Plush

This model is similar to the first one, with the difference coming in from the fabric cover infused with high-density foam.

World Luxury Intimate Collection

The three units that make up this collection are all hybrid models, and they include The Vienna Plush, The Vienna Firm, and The Vienna Euro Top mattress.

In general, the units feature a comfort system made up of Joma wool, latex, memory foam, and gel memory foam layers.

With the Vienna Euro Top, there are micro coils in the comfort system for a more relaxed sleeping experience.

The iMattress Collection

In this collection, you will find two memory foam mattresses, i.e., G10 Firm and G12 Plush, and two hybrid mattresses i.e., XS 10 Hybrid Firm and XS 50.

The G10 Firm and G12 Firm are characterized by a fabric cover that is infused with copper yarns. Additionally, the comfort system features a memory foam comfort layer and a support core made of high-density polyfoam.

 As for the hybrid units, they feature a memory foam comfort layer, a copper yarn-infused fabric cover, and a support core made out of pocketed coils.

2. The Layers

We know we have touched on the different layers of the mattresses as we discussed the construction. However, there is no harm in providing a deeper analysis of the various parts making up a unit.

The top layer is the one that will determine how comfortable you will be as you sleep on the unit. This is because it is the part that will come into touch with your body. So, if the layer offers plenty of bounce and is breathable, your chances of comfort will be significantly increased.

Next up is the bottom layer, which is responsible for the mattress’s support and stability plus allows it to breathe. Therefore, you are likely to find an encased coil system, and the coils would enhance the unit’s breathability, unlike what you get in a standard foam mattress.

The other vital layer to talk about is the edge layer, which helps in providing the product with reliable edge support. This is crucial for maintaining the mattress’s shape and also provides you with more sleeping area.

3. The Cover

This area should not be neglected since it is the first line of defense against potential damage to the sleeping cushion. Also, if the cover is too rigid, it may end up affecting the comfort negatively.

Another thing is that the cover affects the mattress’s heat-retention, and if it retains too much heat, sleeping cool would be an unachievable dream. So, the best cover would be one that gets it right in terms of comfort, breathability, and protection.

Who should buy a King Koil Mattress?

Based on the customer feedback and ratings that we compiled, the back sleepers would be most comfortable sleeping on this mattress. Further, lightweight individuals weighing less than 130lbs would appreciate the comfort and support that this unit offers.

How King Koil Mattresses Compare to other Brands

After reading numerous King Koil mattress reviews, you may get some understanding of what the unit is all about. However, to gauge its performance appropriately, it would make sense to compare it to other competing names in the market.

In this section, we shall conduct brief comparisons between King Koil and other brands, which could be considered viable alternatives.

1. King Koil VS Dreamcloud

Dreamcloud is one of the leading mattress brands globally, and it offers its clients two models, to choose from. They include The Dreamcloud, which is thought of as one of the best hybrid units available, and the Dreamcloud Premier, which is a luxurious piece.

In our analysis, we found Dreamcloud to be slightly superior to King Koil in certain aspects. For instance, it has favorable payment terms with the ‘Buy Now and Pay Later’ financing plan by Affirm.

It also has a 365-day trial, so that allows you to try out the product’s main features. The pricing is another area where Dreamcloud has the edge over King Koil.

So, when these two brands go head-to-head, Dreamcloud would be the clear winner.

2. King Koil Vs. Nectar Mattress

Nectar is another popular mattress brand that you will find in the market. Its main models are Nectar and Nectar Lush, and both are foam mattresses. The area where this mattress excels is pressure-relief and support, and this is the main reason why the brand is highly-rated by side sleepers.

Other notable aspects of Nectar mattress are the high-quality construction, a one-year trial, and a lifetime warranty. The affordability is another crucial factor to consider with a payment plan that many individuals would deem to be friendly.

When you match these two brands, it is clear to see why we would advise that you go for Nectar units.

3. King Koil VS Zuzu

Zuzu is a relatively unknown brand that mostly produces mid-priced items. The firm provides both latex and memory foam units and is mostly of medium firmness. For this reason, they are well-suited for stomach and back sleepers.

In most aspects that we checked out, we concluded that the King Koil mattress would be superior to the Zuzu unit.

4. King Koil VS Personal Comfort

As the name suggests, Personal Comfort is a brand that designs its mattresses in a way that you could customize them to meet your preferences. In this case, we are talking about the firmness which you could adjust to your ideal level.

However, the units’ durability is questionable, and we also wondered why little or no technology was used in the construction. These factors are a few cases we could present as to why we believe this is not a brand that is worth your money.

5. King Koil VS Aireloom

Produced by E.S. Kluft and Company, this mattress became popular with its patented Aireloom lift that increases low-pressure areas when you lay on the mattress. So, when you sleep on it, you would get the cuddling feeling that many users appreciate.

However, the mattress has several turn-offs. First, it is quite pricey, while the durability is not that impressive. Further, some of the models are prone to fast sagging.

Here, we would also recommend that you go for King Koil.

As you can see, there are viable alternative mattresses to King Koil out there. So, before settling for it, it is wise that you take your time to compare the products so that you can see which one has more benefits to offer.
