Better beds, Better service, Better sleep

Sleep City Mattress is a local and family owned business that has proudly served the residents of Northern California for over 35 years.  Mark Thomas and his partner Al Koran started the company with the goal of providing great mattress products for the surrounding community and believe “if you do something well you create loyalty, providing great customer service is the bottom line.”
Four years ago Mckensie Thomas, Mark’s daughter joined the team and supports the company by running the day – to – day operations, making it a truly family run business.

Sleep City now has eight locations in Napa, Sonoma, and Marin Counties. This means there is a Sleep City Mattress within easy, convenient reach of all North Bay households!

Keeping it local

Our community has given us a lot over the years, and we pledge to support it in every way we can. This is why we participate in the GO LOCAL rewards program, which allows customers to obtain discounts and rewards by shopping at locally-owned businesses. To join the program, simply ask for a card at a participating business—you can search for one here. Then, fill out a form or register your card online, and you’ll be ready to use it at any participating store. Sleep City Mattress is thrilled to be a part of this program that connects us with and supports other local businesses. We also try to do our part by carrying products from small, locally-owned companies that are committed to building better products for their customers.

Products and Pricing

Sleep City Mattress carries the same products as the bix box stores but also sources mattresses from boutique, family owned mattress companies as well, providing an array of quality and pricing options for our customers.  Although Sleep City is a locally and family owned business we are still able to offer the same great pricing on mattresses as the bix box stores and we take great pride in being able to do that.

At Sleep City Mattress we are devoted to providing the highest quality sleep products at the lowest prices.
