Comfort King Mattress Factory

Comfort King is the original mattress factory in the Dakotas, founded by Chris Larson in 1995 in Sioux Falls, South Dakota. Our belief is that building a business is all about standing by the product and establishing lasting relationships with customers by offering customized mattresses that can be adjusted for comfort throughout the life of the mattress. We take pride in creating high-quality products that people can trust and rely on, with the community always being a top priority.

The Comfort King Difference

At Comfort King, we believe that everyone deserves to have a comfortable bed that they can truly enjoy. After all, sleep takes up a significant portion of our lives, so why not make the most of it? We understand that our bodies change over time, and our beds should be able to adjust with us. That's why we offer a Lifetime Comfort Guarantee, so that adjustments to your mattress don't cost anything beyond the upgraded materials.

SoftSpot Warranty

Since 1995, we've been perfecting the art of mattress-making. With our research and development experiences, we know what actually breaks down in mattresses over the years and to what degree. Our patented SoftSpot Testing System helps us to identify what customers feel in their mattresses, which cannot be measured with the archaic tool of the pulled string. We stand behind the quality of our products and offer a SoftSpot Warranty to ensure that your mattress will last for years to come.

FLOWT Zero-Gravity Gel

FLOWT was designed over a 3-year period of research and development, which started from a joint venture with the North Dakota State University Engineering Department. FLOWT is the most comfortable cushioning material the mattress industry has ever experienced. Our passion is helping individuals to achieve their health goals, and we believe that quality sleep is essential for a happy and healthy life. That's why we provide a complete sleep solution including pillows, bedding, and adjustable bases, to ensure that you will have the best possible sleeping experience.

About Testimonials

We are proud of the relationships we have built with our customers over the years. Here are some testimonials from our satisfied customers:

"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 prefers. Therefore, I highly recommend the Comfort King mattress for anyone who wants high quality bedding." - Allen D. Unruh, D.C. Chiropractic Arts Center, Sioux Falls, SD

"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!" - Becky
