King Koil Mattress Review – Should You Buy?

King Koil Mattress Review

King Koil mattresses are American-made products that are manufactured with input from the International Chiropractors Association in order to produce mattresses that promote proper spinal alignment meaning King Koil has some of the best mattresses out there when it comes to sleeping comfortably and combatting back pain.

They are known for having above-average temperature regulation features and a build that reduces movement across the bed.

The brand has released a wide variety of them in all sorts of makes and builds. The question is, which one is right for you? We’ve put together a list of King Koil mattresses and their defining features to help you decide.

In our King Koil mattress review, this collection mainly houses hybrid ones. All of them are infused with temperature regulation technology in the form of King Koil’s AvantaGel and iFusion designs.

They are also fitted individually with 1000+ Perfect Contour Reaction Coil Systems which provide added comfort. All mattresses in this collection have silk and wool blend covers that are infused with cooling gel foam for temperature regulation.

Kingsley Line

The King Koil Kingsley mattress line features hybrid mattresses with more focus on innerspring design. These are the mattresses in the line:

1. Kingsley Firm – a medium-firm.
2. Kingsley Plush – a medium soft.
3. Kingsley Euro Top – a very soft.

The comfort layers on the Kingsley Firm and Kingsley Plush mattresses are built with one layer of memory foam followed by a polyfoam layer while the Kingsley Euro Top mattress has two layers of polyfoam beneath its comfort memory foam.

Pros

• This one line is easily the most comfortable that King Koil has to offer.

Cons

• The price range of the Kingsley line is much higher than other similar mattresses from other brands.

Montego Line

The Montego Line features hybrid mattresses fitted with Energex rapid response foam that provide extra comfort and conforming contours to the memory foam layers. These are the ones in the line:

1. Montego Luxury Firm – a medium-firm mattress. This one has memory foam, gel memory foam, and polyfoam layers on top and therefore feels almost like a memory foam mattress out of the three in the line.
2. Montego Luxury Plush – a medium soft mattress. This one comfort layer is simply fitted with memory foam.
3. Montego Luxury Pillow Top – a very soft mattress. This one has a comfort layer system that features gel memory foam and polyfoam layers, between which are extra memory foam inserts.

Each mattress has a constructed support core layer that features foam-encased pocketed coils.

Pros

• These mattresses are extremely comfortable and have plenty of cushioning.

Cons

• The price range of the Montego line is much higher than other similar mattresses from other brands.

The World Edition Collection

The World Edition Collection line exclusively showcases innerspring mattresses that are fitted with a body-conforming encased coil technology known as the 789 Contour Flex EC with K2 Edge.

Everything in this line comes with quilted covers infused with AvantaGel gel foam for temperature regulation and added durability. And as ever, the King Koil standard remains throughout.

Siena Line

The Siena Line only features one mattress: the Siena Firm mattress, which is one with high firmness. Its topmost layer is made from polyfoam for comfort, and its support center is constructed with pocketed coils over a polyfoam base layer, which reinforces the coils’ strength.

Pros

• This mattress is inexpensive and offers decent value for money.

Cons

• The mattress doesn’t have that many pressure relieving properties, especially compared to similar mattresses from other brands that share its price.

Sydney Line

Although it is from an innerspring mattress collection, one of the Sidney line mattresses may be classified as hybrids by some.

1. Sydney Firm – a medium-firm mattress. This one has a top comfort layer made from polyfoam and a second layer beneath it made of more foam for added comfort.
2. Sydney Euro Top – a medium soft mattress. This one has a top comfort layer made from memory foam and a second layer beneath it made of polyfoam for added comfort.

Both mattresses in this line have a support center constructed with pocketed coils over a polyfoam base layer, which reinforces the coils’ strength.

Pros

• The layers in this line focus a lot on cooling properties, making it a great bed for temperature regulation.

Cons

• The foam lacks in thickness, meaning it may not offer sufficient support to some sleepers.

Monaco Line

The Monaco line doubles up on features with its iFusion Lumbar Support foam that helps with spine alignment and to relieve pressure in the back and neck.

1. Monaco Plush – a very soft one.
2. Monaco Euro Top – a medium soft one.

Both mattresses come with an AvantaGel top foam layer and a base layer of the usual King Koil coil system, with the lumbar support foam slotted in between them.

Pros

• The mattresses in this line offer a good amount of back support and have great thermal regulation. On top of that, they’re more inexpensive and decently affordable given what they have to offer.

Cons

• There may be less pressure point relief in this mattress as it lacks comfort layers.

The World Extended Life Collection

There is only one line in this collection, which is focused on innerspring/hybrid mattresses that make use of Talalay latex foam.

Athens Line

Both in this line make use of Talalay latex, a kind of material that is more responsive than memory foam and also often more expensive.

Pros

This is likely to be a very comfortable mattress line. The Talalay latex adds a bounce and responsiveness to the mattress that other models do not have.

Cons

The mattress may sleep hot for some individuals. In addition, it is quite expensive when compared to other mattresses from other brands that use similar materials.

The World Luxury Intimate Collection

This collection currently only has one mattress line of innerspring/hybrid type mattresses. It is easily the most luxurious of the mattresses that the brand offers.

Vienna Line

The Vienna line is an interesting part of the King Koil brand as it features the topmost layer made from Jomo wool as one of its integral characteristics.

All products in this line also make use of the AdvantaGel temperature regulation gel memory foam beneath the Jomo wool layer. These are the mattresses in the line:

1. Vienna Plush – a medium soft one. Under the top comfort Jomo wool and gel memory foam layers, the mattress features GelResponse Latex and iNergex rapid response memory foam.
2. Vienna Firm – a medium-firm one. Under the top comfort Jomo wool and gel memory foam layers, the mattress features GelResponse Latex and iNergex rapid response memory foam.
3. Vienna Euro Top – a medium soft mattress. Under the top comfort Jomo wool and gel memory foam layers, the mattress is fitted with ThermoGraph temperature regulation foam, GelResponse Latex, and iNergex rapid response memory foam. It also has an added layer of coils above its support core in the form of micro coils.

The mattresses also come with the usual 1000+ Perfect Contour Reaction Coil System, meaning all of them to have support cores fitted with foam encased coils.

Pros

• These mattresses provide luxury and comfort thanks to their many layers and superior materials.

Cons

• This line is the most expensive that King Koil has to offer.

The iMattress Collection

This collection features King Koil’s mattress-in-a-box designs. They are all fitted with covers that are infused with copper yarn in order to promote healthier skin and remove odors.

All the mattresses in this line are relatively good quality and reliable, but they all share one negative side: they are often more expensive than other similar ones from competitor brands. These are the mattresses in the collection.

1. G10 Firm – This medium-firm mattress is fitted with a top layer of TriFusionFOM for temperature regulation, followed by rapid response iNergex memory foam and a high-density polyfoam support base that conforms to the body and adds to the mattress’ durability.
2. G12 Plush – This medium-soft one has the same features as the G10.
3. Hybrid Firm – This medium-firm mattress has a top comfort layer of iNergex rapid response memory foam and high-density polyfoam. Like mattresses in the World Edition Collection, the Hybrid Firm has the 789 Contour Flex encased coil system with K2 Edge as its base support.
4. Hybrid Plush – This medium-soft one has a top layer of TriFusionFOM for temperature regulation, followed by rapid response iNergex memory foam. It has the same coil support base as the Hybrid Firm.
5. XS 10 Hybrid Firm – This medium-firm mattress is one of the more luxurious in this line. Beneath its copper-infused cover, it houses iFusion technology foam that regulates the mattress’s temperature, and its support base is a 630 Contour Luxury Plus Encased Coil System.
6. XS 50 Hybrid Plush – This medium-soft one has the same features as the XS 10.

About King Koil Mattresses
