King Koil Mattress Range and Construction
King Koil sells innerspring, hybrid and all-foam mattresses across five collections. These collections contain 20 mattresses altogether and offer consumers a very wide range of choices. In this section, we’ll look at the construction of all five mattress collections.
The King Koil World Edition collection features five innerspring mattresses in a range of comfort layers and finishes. The mattresses are put together as follows:
The King Koil Monaco Plush mattress has a pocketed innerspring core. The comfort layers are made from polyfoam and gel-infused memory foam which gives the mattress the ability to conform to the shape of your body. The mattress is finished with a gel-infused foam cover.
Monaco Euro Top
The King Koil Monaco Euro Top mattress has a similar construction to the previous model. However, it offers extra support for your lower back as its support is arranged into zones. This could make it a good choice for people who suffer from back pain at night.
The King Koil Siena Firm mattress has a supportive base layer made from individually pocketed springs. Its polyfoam comfort layers that give it a firm and responsive feel, so it doesn’t give the ‘sinking in’ sensation that you get with traditional memory foam. Like the Monaco models, it has a gel foam quilted cover.
The Sydney mattress is another innerspring mattress with comfort layers made from polyfoam in either a Firm or a Euro Top finish.
The King Koil World Luxury collection features six different mattresses, all of which are innerspring (Kingsley) or hybrid (Montego) models. The World Luxury collection is constructed as follows:
The Kingsley mattresses have supportive innerspring cores. There are three options if you select this family of mattresses: Firm, Plush and Euro Top. Each spring in the support system is contained in its own polyfoam pocket and the comfort layers are made from polyfoam and memory foam. This means that they can conform to the shape of your body and relieve pressure. Each mattress features a breathable cover made from memory foam, silk and wool.
Like the Kingsley mattresses, Montego models feature foam-encased innersprings and a gel foam and silk-wool blend cover. The comfort layers are made from polyfoam, regular memory foam and gel foam. King Koil Montego mattresses come in three different options: Luxury Firm, Luxury Plush and Luxury Pillow Top.
World Extended Life
The King Koil World Extended Life collection features the Athens mattress, a latex and innerspring hybrid. The support layer is made from coils that sit inside their own polyfoam pockets, and it has an adaptable comfort layer of Talalay latex foam sandwiched between two layers of polyfoam. The mattress is finished with a gel foam cover and you can select between Firm and Plush.
World Luxury Intimate
The King Koil World Luxury Intimate collection features the Vienna hybrid mattress. It is available in three firmness options: Plush, Firm and Euro Top. The mattress gets its support from a layer of pocketed springs surrounded by polyfoam and the comfort layers are made from latex, memory foam, gel and wool.
The iMattress collection contains four different mattresses. Two are all-foam and two are hybrids.
The King Koil G10 Firm mattress has a base layer of highly supportive polyfoam and a comfort layer of memory foam. Its cover contains a copper infusion that helps you to sleep cool by wicking heat away from your body.
The G12 Plush mattress features the same construction as the G10 Firm. However, it has a softer feel.
XS 10 Hybrid Firm
The XS 10 Hybrid Firm is a memory foam and innerspring hybrid. It features a cooling fabric cover containing copper fibers that can draw heat away from your body.
XS 50 Hybrid Plush

Is a King Koil Mattress Right for my Sleeping Position?
King Koil mattresses can suit any sleeping position because its collections contain a wide range of mattresses in different materials and firmness options. So, you should be able to find a King Koil mattress that suits your needs well. Which King Koil mattress you should choose comes down to several factors including your body weight, sleeping position and sense of comfort.
As a rule, people who sleep on their sides need a softer mattress. This is because a softer mattress will reduce pressure on your hips and shoulders by allowing your body to sink in. Therefore, we recommend that side sleepers weighing less than 130 pounds select a Soft or Medium Soft King Koil mattress. Side sleepers with average body weights or higher may prefer a Medium mattress.
Front and back sleepers tend to need firmer support to keep their spine in a healthy alignment. Some people with this sleeping style may find a Medium King Koil mattress comfortable, but if you have a bodyweight over 250 pounds or a painful back condition, you may find a Firm mattress gives better support.
King Koil does not currently make a Medium Firm (universal comfort) mattress, so combi-sleepers and couples with differing sleep styles are probably best off going for a Medium option. If this doesn’t feel firm enough for you, it’s probably worth looking at a different mattress brand available in Medium Firm such as the Nectar.
Do King Koil Mattresses Sleep Cool?
Many King Koil mattresses sleep cool. However, the answer to this question depends on which model you buy. King Koil’s hybrid and innerspring mattresses are breathable because they feature support cores made from pocketed springs, which means that there are gaps between the coils. So, air can circulate more freely, allowing heat to escape during the night.
King Koil also uses materials in some of their mattresses that are specially designed to wick away heat. Many King Koil mattresses feature layers of memory foam containing heat-wicking gel. Beds in the iMattress range also feature comfort layers made from copper-infused memory foam. Copper is a great conductor of heat, allowing heat to away from your body while you sleep. If you tend to sleep hot, we recommend selecting a King Koil mattress featuring these cooling sleep technologies.
Where to Buy
King Koil does not sell its mattresses through the company website, but you can buy a King Koil mattress through third-party brick-and-mortar retailers. You can find your nearest King Koil retailer by following this link: https://kingkoil.co.uk/find-a-stockist/
There is no specific shipping information for King Koil mattresses because they are sold exclusively through third-party stockists. Each third-party retailer will have its own shipping policy, so you should discuss shipping arrangements and fees with your retailer before you buy.
King Koil does not offer a white glove delivery or old mattress removal service. However, your mattress retailer may be able to provide these services for you depending on its company policy.
Sleep Trial and Returns
King Koil does not provide a sleep trial for its customers and does not have a brand-specific returns policy. This is because King Koil mattresses are only sold by third-party retailers. So, you should ask your chosen stockist about sleep trials and returns before buying, as these will vary from retailer to retailer.
King Koil mattresses come with a 10 or 25-year warranty, and the total coverage period depends on which model you buy. The warranty entitles customers to have their mattress repaired or replaced if it has a manufacturing fault. However, customers are responsible for paying any shipping costs associated with repair or replacement. The warranty covers indents deeper than 0.5 inches in the surface of the mattress if it has a 25-year warranty, or 1.5 inches if it has a 10-year warranty and protruding springs. King Koil warranties do not cover normal wear and tear, bent border wires or damage caused by owner misuse such as staining.
These warranties are non-transferrable. This means that they are only valid for the original purchaser and do not apply if the mattress changes ownership.

Alternatives to the King Koil Mattress Range
King Koil mattresses will not be the right choice for every consumer. If you’re looking for a mattress brand that offers a wide range of choice and good pressure relief, a King Koil bed may be a good option for you. However, there are question marks over the durability of King Koil mattresses. It’s important to be aware that there are many long-lasting mattress brands out there, so it’s worth shopping around.
Here at Sleep Aim, we always suggest checking out our top three products before committing to a mattress: the Puffy, the Novosbed and the Nectar. These three mattresses are all-foam options that offer customers a good balance of support and comfort for a fair and affordable price. Even better, they are highly durable. So, any one of these mattresses should stand the test of time with proper care.
We’ve reviewed a huge number of mattresses, and the Puffy has come out on top. This affordable memory foam bed is our #1 mattress recommendation because it combines comfort, support and value for money in one durable mattress.
Unlike many memory foam mattresses, the Puffy mattress maintains a cool and comfortable temperature. This is because the manufacturers have used innovative sleep technology to help make it as breathable as possible. So, the Puffy allows you to get the benefits of memory foam without the overheating so common with foam beds.
So, what type of sleeper does the Puffy suit best? We think side sleepers are most likely to give Puffy the thumbs up. This is because its medium firmness lets your body sink in comfortably without compromising in terms of support. That being said, front and back sleepers may well love it too. However, those with higher bodyweights may benefit from a firmer model like the Nectar mattress.
The Novosbed is another highly recommended product for those looking for the best memory foam mattress in 2023. Like many similar mattresses, it has a supportive foam core layer with soft, conforming memory foam comfort layers. So, the Novosbed provides good spinal and pressure relief at the same time.
The Novosbed sleeps cooler than most comparable models because it features advanced aerated foams. These foams allow better air circulation than traditional memory foam, so body heat can escape easily during the night instead of building up.
The Novosbed is available in three firmness settings. If you want to fine-tune the mattress, you can customize the firmness more by using their Comfort+ service. So, the Novosbed could be a good choice if you have very particular support or comfort needs.
The Nectar mattress is a breathable memory foam bed and is the brainchild of the well-known online mattress retailer Nectar sleep. Its structure gives sleepers good back support thanks to a dense polyfoam core layer, and an adaptable comfort layer reduces pressure on your joints while you sleep.
One of the stand-out features of the Nectar mattress is its responsive feel. Nectar achieves this by using open-cell technology in the comfort layer, creating a more open structure that gives it more bounce and less sinkage than standard memory foam. Many people don’t like the deep sinking sensation of memory foam, so the Nectar might be right for you if you want deep pressure relief with a bouncier sleeping surface.
Another benefit of open-cell technology is that it makes the foam more breathable, allowing air to circulate beneath your body while you sleep. More air circulation means less heat retention, so the Nectar sleeps cooler than many of its competitors.
