However, if you have a disability we are here to help you. Please call our disability services phone line at (406) 256-5464 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability.

Exceptional Delivery for Exceptional Guests

I know what you’re thinking: "Delivery is free, but the SERVICE is going to cost extra." Nothing is further from the truth. At Mattress King, we LOVE to serve our guests at every opportunity.

That is why we have our "Red Carpet/White Glove" delivery service.

It all starts with scheduling a delivery time during a two-hour window on a day that works FOR YOU. We then either give you a call or text (your preference) the day of your delivery when we are headed to your house.

Upon arrival, we sweep (or shovel) a clean path up to your house. We then roll out our Mattress King logo rug and before we enter your house we put protective booties on our shoes. EVERY. TIME.

We then offer to dust or vacuum where your new bed is going to be delivered. As mom always said, "A clean home is a happy home."

When we unwrap your mattress we wear white gloves to avoid getting dirt on your brand new bed.

Lastly, we dust, swiffer, or vacuum up any mess we made. Again, because mom said, "Leave it in better condition than you found it."

Then you enjoy a great night’s sleep. Delivery. Simple and Easy.

can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
