Made from high-grade materials

Don't throw your money away: on a cheaply-built mattress, box spring, or bedding set. At Doms Mattress Store, you can rest assured that your investment will go further.

So now our customers can enjoy: "the best for less"!

If you're short on cash, don't worry! You won't find a more-easier mattress store to finance a bed.

Conveniently shipped in-a-box

The days of high mattress delivery fees and hauling a bed that weighed over a hundred pounds are long gone!

When I started my mattress company in April 2016, I did everything required for my customers to get their bed sets. You would think I was crazy: if you saw me driving on the main street with a king-size mattress tied on the roof of my 2007 Chevy Impala sedan. Just know: mattresses combined with aerodynamics are not a good combination, but by the grace of God, I never experienced a traffic ticket or accident because of it.

My business began to grow, and it became overwhelming for me to continue operating this way, so I hired a self-contracted delivery guy with a pick-up truck.

Things were good for a couple of years, but I was always limited in the number of people I could reach.

Finally: after much trial and error, I created a mattress company that delivers across the entire country, fast and free!

Testing a mattress in-store may not always be the optimal choice. Discover why.

The debate between Mattress Quizzes and Trying Out Mattresses In Stores revolves around finding the perfect mattress for a restful night's sleep. Traditionally, individuals tested mattresses in stores, but with the rise of mattress quizzes, a new alternative has emerged. These quizzes offer personalized assessments, considering factors like sleeping position and material preferences, leading to informed decisions tailored to individual needs. However, physically testing mattresses in stores has its drawbacks, including limited insight and pressure sales tactics. At Dom's Mattress Store, we recognize the importance of personalized comfort and offer a comprehensive mattress quiz to guide you towards the perfect choice. Experience the difference and embark on a journey towards a rejuvenating night's sleep by clicking here to take the Mattress Quiz.

Excludes phony warranties (click here to discover the reason)

In a market inundated with mattress retailers promoting extravagant sleep trials and lengthy warranties, Doms Mattress Store stands out as a trailblazer. While other stores emphasize these offerings as essential components of mattress shopping, Doms takes a different approach. At Doms, you won't find sleep trials or intricate warranty fine print, and there's a compelling reason behind it.

Congratulations on finding the best online mattress store in the world. With all kidding aside, did you know that: a good night's rest can help improve your overall health?
