King Koil's Specifics

King Koil mattresses are sold in a variety of retailers across the country. When it comes to their mattresses, they offer mostly hybrid mattresses with pocketed coils. Most customers are initially comfortable with these mattresses and report good things, but there are some complaints about the quality for the price.

If you are looking for a well-rated pocketed coil mattress at a competitive price, see our list of top rated hybrid mattresses, and specifically the Dreamcloud mattress offers high material quality for the price.

Quality of Materials

King Koil has a partnership with the International Chiropractors Association and has used that as a powerful instrument for building consumer trust. The materials used are intended to align the spine properly for a comfortable sleep. There is not a lot of information on the breakdown of materials used in King Koil beds. This is something important to discuss with your local retailer if you are considering buying a King Koil. Ensure that they use certified foams that don't offgas toxins. Additionally, know that these mattresses are priced high versus many comparable online alternatives so make sure that there are sufficient add ons thrown in to make up the difference.

Mattress Types

King Koil offers a variety of mattress options. They all provide different firmness and price points. We'll go through all of these models in detail below...

SmartLife Collection

In recent years, there have been some exciting new developments in sleep technology from brands such as Sleep Number and Eight Sleep. One of the newest additions to the King Koil lineup, the SmartLife Collection, are smart matresses developed to be adaptive and adjustable to the sleeper. This line features responsive memory foam, patented body sensing technology that automatically adjusts to the sleeper's body shape/height/weight through the use of air pockets, and even a massaging relaxation mode. The SmartLife beds also provide sleepers with sleep quality tracking, the ability to manually adjust the firmness on each side of the bed, and the ability to set a smart alarm that creates gentle waves in the bed when it's time for you to wake up. For sleep technology lovers, this might be a mattress to consider. However, owning a smart mattress can be costly and this is one of the most expensive mattress options made by King Koil.

Intimate Collection

The Intimate Collection is one of King Koil's luxury mattress lines. With tufted quilted top layers that elicit luxury hotel feels, this collection also features innovative materials. In the top comfort layers, their mattresses feature graphite infused memory foam, micro coils for less partner disturbance, and Talalay latex infused with graphite. These layers facilitate greater cooling and also work in conjunction with the traditional pocketed coil systems below. Overall, these mattresses get good reviews from customers, but price point is somewhat higher than online competitors.

Xtended Life Collection

The Xtended Life Collection is their line that is designed to last. With firm high density foam and responsive graphite latex, this mattress is best suited for larger sleepers that have struggled with sagging mattresses. Overall, customers will do well with this option, but some may experience it as overly firm depending on body size.

iBed Collection

The iBed Collection is King Koil's latest innovation when it comes to cooling and luxurious sleep. The iBed Collection features 11'' thick hybrid mattresses with over 1000 pocket coils/micro coils, graphite infused memory foam to help disperse heat, and are available in both firm and plush options. Depending on the model, the iBed mattress will either have a layer of micro coils that rests on top of layers of memory foam, or memory foam layers that rests on top of a pocket coil system. While these mattresses may provide sleepers with a cooler night's sleep, some sleepers may wish for more edge support in the micro coils.

MHybrid Collection

The King Koil MHybrid line puts the focus on advanced memory foam technology and features HypurGel cooling technology and Graphite infused Talalay latex. With somewhat slimmer profiles than the Intimate Collection, these mattresses are more budget-friendly. With a variety of firmness options, customers have good things to say overall. However, there were some concerns about durability over time.


King Koil's Luxury line may be less so than their other offerings, with a focus on traditional pocket coil support systems, and less emphasis on thick comfort layers. That said, their Contour Elite pocketed coil system will do well to minimize partner disturbance. Overall, customers will appreciate the simplicity of these designs, but there are some that may crave more long-lasting comfort.

iMattress Collection

The iMattress line offers additional pressure point relief for those that are looking for a memory foam feel, but with pocketed coil support systems. The mattresses come with iFusion™ open cell memory foam technology for greater air flow and heat dispersion. Overall, these mattresses are somewhat more competitive on price point, but there were some concerns about durability for the price.

Great Quality for Price

This mattress is comfy! It's not too firm and not too soft. I love it! I was a little nervous before I bought it because the price is so low. Once I went in the store and tested it out, I knew I was going to get my monies worth. Granted I've only had it for about a week now, even my boyfriend has confirmed it's super comfortale. Get it while it's on sale.

Buyer Beware - Not a standard sized bed!

I bought the twin mattress and much to my dismay there was about a 4 inch gap between the mattress and my bed frame. After measuring the mattress I realized it was only 36 inches wide, not the standard of 39 inches (despite the website listing it as 39 inches wide). I finally got a hold of the manufacturer and they said that their twins are "intended" to be 38 inches wide but that each one can differ by up to two inches. So you're basically left with a mini-twin. I will be returning this.


It's pretty comfy for the price but honestly I could have gotten cheaper at another matress store, definitely shop around more. It's not very thick and the euro top seems like it will be flattened very easily I give it maybe a year before it starts losing its comfort completely

Guest room

My first set of guests found this to be very comfortable. I slept in the guest room to try it out and found it very comfortable. I am very pleased with this purchase and will purchase future items.

Cheap Mattress for College Kid's Appartment

Nice product at the right price. My child needed a mattress for a new college apartment. We saw many options and even ran into a manufacturers rep at the store who helped us with good advice. As usual, the experience was great


love this mattress very comfortable the never disappoint

Instant Comfort

Great price and such an amazing mattress. The level of comfort is undeniable. I'm very happy with this product and would recommend it in a heartbeat.

Great mattress

This mattress was purchased for a bedroom that is only used for guests and when child is home from college. The mattress is very comfortable and the price is perfect for this situation. We have had it about a week and my kid loves it, it's 12:20 pm now as I write this review and she is still sleeping.

Incredible mattress!

Buying this mattress was an amazing investment. Such a comfortable bed to sleep on and the service and delivery was very prompt and professional.

Very satisfied

Very happy with what I bought slept like a baby. The delivery guys came set it up fast. Very happy with the service.

My husband and I are sleeping so much better...

My husband and I are sleeping so much better since purchasing this mattress. It's not too firm or too soft, so you get support without feeling like you're sleeping on a board.

King Coil Mattress

We love our new Mattress! The comfort and quality is unbelievable and for what we paid for it...we just love it!!


I purchased two of these mattress for my boys, without them being there to try them, and they just love it. They said it's so comfortable that it just conforms to their bodies. Mind you my 15 year old is 262lbs and said the bed is like a giant blanket. So hats off for a great product at a reasonable price...

Superb Buy

I recently stayed in a bed in a breakfast in Maine--and loved the mattress I slept on. (I've got neck and shoulder issues to the mattress is often crucial.) I found a similar King Koil mattress and Raymour and Flanigan. The price was right; the delivery was prompt. "For this relief much thanks." Happy with my purchse: feels good!

Supper Happy With Our King Koil Mattress Purchase

When choosing a bed we needed a firm mattress with back support for me but yet some cushioning for my husband and the King Koil Perfect Response Elite Lakeside Pillowtop was "the perfect" choice. Very pleased with our decision and we even received next day FREE delivery - very nice!

great buy

I love my new mattress -and the service that came with it.

Great Delivery Time

The bed is great. It came when they said it would and the sales person was wonderful in working with our family.

Just right

Bought this for my guest bedroom and it was given an A plus By my first guest. She couldn't believe it was a firm mattress. Would highly recommend.



Hello my new Mattress

I have a California King Mattress and it is the best.... I was not sure of down sizing to a Queen Mattress, but I must say that it was the best choice I love the way my body rest and the best part is that my husband and I are know closer....



Sleep in comfort

It's hard to get out of bed after sleeping on this very comfortable mattress. You look forward to relaxing at the end of the day. I like it very much. Keep in mind, coupled with the box spring, it is very high. Can't go wrong with this one, unless you like it extremely firm. It has the right kind of firm but soft too.

Queen King Koil

Very happy with our purchase! Bed is comfortable. Not too firm, not too soft. Great quality for a great price!

Cloud 9

The mattress is very comfortable. It's the best sleep I've had in a long time. It is a 5 star hotel quality mattress. I'm in love. I must stress that the hubby that works at night and have Insomnia also agreed that his sleep has been much better. Thumb's up.

Absolutely love my mattress

I absolutely love my new bed. Best experience it's comfortable for my back after I come home from work cause I work 19 hours of the day doing labor and I just needed a new way to sleep. This is one of the most comfortable beds I've ever slept in and I highly recommend it to everyone.

new Matress

The store was great the product was well priced and it was a convenient purchase. Loved the salesmen [Associate name removed].

Highly recommended

This mattress has just enough firmness topped with a pillow top that has just enough softness! The price is perfect and the customer service was out of this world. No one trying to force me to the most expensive products in the store.

Very Happy

I am very much enjoying my new mattress. I was afraid it might be too soft but I'm glad I went with the softer mattress over the more firm mattress. While this is soft, it is still very supportive. This mattress is great quality for a good price.

great mattress...

great mattress sleep like a baby love it so much it is great

Excellent & good quality

Best decision i made for my son he loves his new bed. Raymour and flanigan alway have good quality furniture which last a long time. I know when i shop with them im getting good stuff.

Just right for the spare room!

I needed a mattress for my fathers spare bedroom so I had a place to sleep when I visited. I didn't want to spend a lot but I wanted something that was nice and comfortable. This mattress is it! I have slept great when visiting him now and the Sales associate Tom P. in Clifton Park listened to my needs and took care of everything! Thank you Tom!

Wonderful comfort!!

very comfortable but still with support!! Very happy!!


This mattress was purchased for a guest room and has only been slept on once with a report that is was very comfortable. The salesman was very helpful and polite. The delivery team were very helpful and delivered quite timely


I really like this mattress. It's really comfortable and it feels like I'm sleeping on a cloud.

Welcome to a restful night's sleep

My old mattress was still in good looking shape, but had outlasted the years I needed an extra firm mattress. My new King Koil plush is so comfortable, I sleep right through the night. Both my husband and I are well pleased with this purchase.

Mattress is unbelievably comfortable...

Mattress is unbelievably comfortable. My wife and I love it so much.

Great price

So far so good! Great price for the quality. I'll write another review after about a month or so

Great mattress

I am so happy with my purchase. I haven't slept this well in a long time. I definitely Recommend this mattress. The salesman was very knowledgeable and he listened to my needs.


I am very happy with my king coil mattress purchase. In the past I have always bought Sealy's. It is very comfortable and I am happy with it. Also the service at the store and the delivery was very good. I am also very happy with the guarantee on the mattress.

Not what I expected mattress already had an indentation after sleeping on it for the first time.

Mattress after the first night of sleep had a indentation in it already. Was or is not as comfortable as I expected.

Extremely Satisfied

I was very pleased with the delivery men, they were great. Being disabled and unable to dismantle my other bed, they went the extra mile and did it for me. They were very professional and pleasant to deal with. I will be making all my future purchases at this store, as their prices are also very good.

King Koil Mattress & Boxed Spring

Great buy! Old mattress and boxed spring were removed and new mattress and boxed spring was delivered and set up in 5 minutes.


I purchased a king koil mattress and box spring from Van Vreedes in 2014. It had a 10 year warranty. USELESS!!!! After less than 2 years it totally caved in. I flipped it every 2 months. So they send you a pack to take pictures measure with ruler how bag the cave ins are. I slipped out of bed every am landed on floor. Yes that bad! Well I was approved they brought it in and then Van Vreedes wanted 89.00 for delivery fee!!! On this set that had a 10 yr warrany. Van Vreedes manager told me he has to pay his boys to do it. I said it never shouldof happened. Here 2019 same ossues caved in on all sides. I submit pictures and paper work this summer and was denied. They said there was nothing wrong with it!! Do not trust a 10 yr warranty useless. Van Greefes won't back up products and say I had to go to the Manufacturer of king koil well guess what MAIL BOX FULL for a month of course!! So today I went to Menards to buy another matress and box spring. Still having a full 4 yr warranty of this King Koul Mattress. They are all so nice and happy to take your money but totally ditch you when you have a problem. Just a heads up. Happy 2020...

Pathetic Luxury Mattress and service issues

We purchased an Ultra Luxury Mattress Paradise worth around 55000/- in June 2017, the mattress started to go all inside when anyone sat or lied down. Customer care responded but they just fixed the mattress like a temporary fix in July 2019 which is now spoiled again. My mother is having cervical now because she recently realized the pain due to poor posture while sleeping. The company said if any problem in the first 4 years they would change the mattress thereafter, mend for the next 6 years. I hope the company works better on their after sales and take this feedback seriously which has brought my mother so much pain. I will follow up more with King Koil so for the viewers please take a rational decision when buying such expensive Mattresses.
