What People Are Saying About Comfort King

Allen D. Unruh, D.C.
Chiropractic Arts Center Sioux Falls, SD
“Dear Comfort King, I found that the bedding produced by Comfort King compares with any on the market including Sealy Posturepedic. In addition, they are much more affordable and can be custom designed to whatever type of firmness and individual perfers. Therefore, I highly recommend the Comfort King mattress for anyone who wants high quality bedding.”
Becky
“We came to Comfort King in Sioux Falls with a special request. We needed a mattress we could easily move around and fit in a odd space. Travis helped design a perfect solution for our space. We tweeted it a bit, Travis made it better. It’s absolutely perfect. Very comfortable, easy to move. Thanks, Comfort King and Travis and the crew!”
Casey Bartz
“I want to write a note to let you know about the great delivery crew you have. My mattress and powerbase were delivery perfectly on Thursday, April 21st. They were spot on for time–I was actually a little late, but they politely gave me a voicemail saying they had arrived at my house. They were polite and removed their shoes, they were neat with the unpacking of the powerbase, and removal of the packaging at the end. They helped me move the old mattress and box spring to the detached garage. I have a small old house and it was a tight squeeze for moving everything, and I know that my family dreads helping me move things because of the tight parameters and hardwood floors, but they did a great job. I applaud the two gentlemen for their professionalism and also customer service. One explained the remote very clearly and also the proper care for the bed (rotating it), etc. They made sure that any/all my questions were answered before they left. I will highly recommend Comfort King to my friends and clients!”

“I thought I would drop you a note and express my satisfaction with your product. We have had the Comfort King mattress now for well over a year and are as happy with it as the day you brought it out to our house. You can be proud of the excellent product your firm manufactures. Thank you!”
Dan N.
“Dear Comfort King Over the years, we’ve purchased a total of 7 beds from Comfort King. The first was well over ten years ago. We’ve had it adjusted a couple times and the guys in the Fargo store were great to work with. When we first bought the bed, it was more comfortable with a softer mattress and as we’ve grown older, we needed more support. With the lifetime comfort guarantee, they were able to firm up the mattress – which is a lot better than having to buy a new bed. Overall it’s just as comfortable now as the day we bought it. Last year we moved that bed to the cabin and upgraded to a larger king size bed with the somnigel. We are very impressed with the new bed… just when you think you couldn’t sleep better, they invented something new. All of our kids have Comfort Kings mattresses and we have a few extras for guests. I highly recommend Comfort King Mattress Factory. They have earned our business and we wouldn’t shop for mattresses anywhere else.”

“I have a couple mattresses from comfort King 1 is 9 years old I wanted to firm it up and Ben made suggestions to make it more comfortable and not an expensive fix! I’m extremely happy with the outcome ! I now have a mattress that feels like a new one again and thanks to great suggestions and great customer service I will be able to continue to enjoy my mattress for a few more years, thanks Ben!”
Heather B.
“We bought our bed a few years ago and recently were having a miner issue with firmness. I called the store and told them what was happening and they told us to bring it back to the store and they would make some adjustments to it. It was done the same day and the customer service was great! Thank you!”
Jason
“Greetings, I would just like to thank you for your wonderful service of my Comfort King mattress. I purchased the full size mattress & box spring set in November of 2011. On June 4th, 2013, I requested the bed to be more firm and without hesitation or questions you held true to your word and picked up the mattress, made the correct adjustment, and delivered the mattress back to my home in record time and at minimum expense. Businesses like yours are a dying breed where they follow up on their promises and place the customer first! In addition, the two young men that picked up the mattress and delivered it back to my home were polite and considerate! Once again, thank you for being a shining example of what modern businesses should strive for!”

Hotel Donaldson
“At The Hotel Donaldson our mission is to create memorable experiences by celebrating our region – our food, the art, the music and the mattresses! We’re so proud to tell our guests that they’re sleeping on a mattress from Comfort King, made right here in Fargo. Many guests have purchased a mattress after spending the night with us. It’s what my family and I sleep on at home. You can spend a night at the HoDo to try one out, but you don’t really need to.”
Kevin Soiseth
“Dear Comfort King, Our new mattress was delivered yesterday. We bought a King size Divine and paid to have it delivered. I thought you should know that the two delivery guys that brought it and carried it up to our second floor bedroom did an exceptional job. Our staircase is obstructed by a low ceiling at one point and it took a huge amount of effort and ingenuity to get that mattress to fit past that obstruction. Your guys busted their tails getting that thing up there and took great care to ensure it wasn’t damaged. Obviously your concept of quality carries through even to the delivery. Please thank those guys again for a job well done!”

“Hi Guys, It’s Lynn, I haven’t had my new bed very long, BUT I had to tell you, THANK YOU! I vacuumed today, and you may think that that isn’t anything to shout about, but it’s been months since I’ve been able to do that hum-drum chore myself. My back has been so much better since I’ve slept on my bed. I did laundry without having someone carry it to the washer. I can’t put into words how much less pain & aches I have now. I’ve had to have the steroid shots in my low back several times, but I think I may not have to have that for some time to come!! THANK YOU!”
Megan W.
“Never go anywhere else! This place is the best- not only do they have the best mattresses, their costumer service is outstanding. I needed a mattress last minute and they went out of their way to help me. All of the mattresses in our house are from them. Not only do we sleep better then ever but so do our guests. Thank you Comfort King!”
Mike S.
“Just three words….I love it. For the first time in a very long time I slept on a quality box spring and mattress. Slept completely thru the night. No aches or pains when I woke up. The buying experience was great. Thank you Comfort King!”
Orlin & Louise B.
“They were prompt, courteous, and have great customer skills. They even offered to put the bed skirt over the box spring before they put on the new mattress. See you in 10 years! “
Rebecca Cooks
“Dear Comfort King, Thank you Chris for the opportunity to continue to give our testimony. The Bed is still the best investment we ever made in our life in connection to our health. Did I forget to also tell that because of his sleep quality is so much better, his diabetes has improved recently by leaps and bounds. Dr. Oppenheimer was able to take him off his daily 3 insulin injections and just oral medication to keep it lower, and his blood pressure medications have been cut down in half each day. Frank is a different person in the last 4 months. The loss of 22 lbs was from getting off insulin and sleeping better and that includes improved oxygen. People just don’t realize ALL THE BENEFITS of a good deep sleep and for 6-8 hrs. I’ve had 4 sleep studies in the last 4 years and it always came back that I, what they call an alert sleeper, I have never in all my life gone into REM sleep and suffer from chronic fatigue, insomnia…since I don’t wake during the night any longer I am now getting that quality sleep. I always thought that the bed we had was so comfortable…Well…all of us don’t know what benefits there are in just searching and looking everywhere for an answer. I usually didn’t pay any attention to commercials about beds because I thought I had the best bed. I believe with my whole heart and soul that God chose Comfort King as a channel to get my attention and that he used you and your employees to speak through, that is the best blessing I can imagine, no one knows when God is working in everyone, believer or not he continues to work in and around people. So Thank you”

“I bought my twin mattress 22 years ago, about 6 months after they opened in Fargo and it was from the owners son. I have had it back 2 times to get foam in 20 years. My friend bought a king mattress from Comfort King over 15 years ago and he worked selling beds for competitor that sold other brands. Comfort king it not the lowest priced but it sure lasts longer.”
Scott W. Nelson
“Dear Comfort King, I recently purchased a mattress from your Sioux Falls store. My wife and I were impressed how it made an immediate change in our sleep. First and foremost is the fact that we are able to rest comfortably in virtually every position. As for my wife, she wanted me to mention the courtesy of your staff. Once again we would like to thank you for the product and service you provide. I’m sure it will change our lives forever for the years to come.”

“John and Steven delivered right on time and we’re very professional. Thanks for a job well done guys!”

Specialty-size mattresses can typically be assembled and delivered to you in less than two weeks. Contact our Sioux Falls or Fargo store for details.

Can you make me a mattress for my antique bed?

Yes. Comfort King can custom-build a sleep set for you in any size or shape. For antique beds, we recommend you measure the width and the length of the inside of the bed frame prior to speaking with a local store. Alternatively, we can measure the antique bed for you. Specialty-size mattresses can typically be assembled and delivered to you in less than two weeks. Contact your local store for details.

Does Comfort King offer foam mattresses?

No. Foam cores are inferior to pocketed coil innersprings in both support & durability.

Can I purchase a mattress only?

Yes, you can purchase a mattress only. However, your mattress is only as good as the support beneath it. We recommend purchasing a mattress and a foundation at the same time in order to receive the best comfort and support.

Why should I buy a mattress and a foundation at the same time?

A mattress and a foundation are designed to work together. An old foundation will usually lack the uniform support that is necessary for your new mattress; resulting in premature “sagging”. We recommend purchasing a new mattress and foundation at the same time in order to receive the best comfort and support.

What does Comfort King’s warranty cover?

Comfort King guarantees all sleep set purchases from defects in workmanship and materials on a 100% non-prorated basis.
CK also offers the exclusive SoftSpot Warranty.
Should service be needed, your mattress or foundation will be repaired (at Comfort King’s discretion) at no charge. You are responsible for any transportation charges. Transportation costs apply. Contact our Sioux Falls or Fargo store for details. This warranty does NOT cover normal wear, including body impressions less than 1.5 ” deep.

I moved away from my original place of purchase and I have a service issue. What should I do?

In the event your mattress or box spring needs servicing, please contact the Comfort King location at which it was originally purchased.

Do you offer shipping to areas where there isn’t a Comfort King? What are the shipping costs?

Yes, Comfort King will ship products to you even if there is no Comfort King location in your area. Customers are responsible for shipping costs, which vary by product and destination. Contact the closest Comfort King location to you for details.
