Frequently Asked Questions

What is your return policy?

As the oldest mattress store in California Mattress King is known for selling the highest quality mattresses at wholesale prices.


With 90 years of experience we are confident in our ability to find you a mattress that meets your comfort level. However if you find yourself counting more sheep than sawing logs don't worry - we have your back!


It typically takes 30 - 60 days to properly break in a new mattress. Much like a new pair of shoes, it also takes time for your body to adjust to a new mattress.

The 30 Day Comfort Exchange* - If after 30 days you are not completely satisfied with your new mattress you can exchange it for a new mattress of equal or greater value.

If the customer chooses a mattress of greater value the customer will be charged the difference between the two mattresses, plus tax, and delivery fees.

 *Mattresses with stains, markings, or strong odors will not qualify for the 30 Day Comfort Exchange. To insure you qualify for the 30 Day Comfort Exchange it is recommended all customers purchase a mattress protector for their mattress.

Do I have to get a box spring when buying a new mattress?

Yes and no. Deciding if you need a new box spring will be determined by the type of bed you will place it on. Do you already have one? How long have you had it? Is your bed a platform, slats, or open frame?

Consider this: the box spring acts as the foundation of the bed. It keeps the mattress flat and provides support for the mattress by acting as a shock absorber. 

Are there cancellation fees?

Due to the limited space in the warehouse we oftentimes will have to order your new mattress before we deliver it to your home. Because of this there is a 25% restocking fee on all cancellations.

Do I need a mattress protector for my mattress?

A mattress protector is recommended for every mattress. Not using a mattress protector on your mattress could void the manufacturer's warranty. 

What are the benefits of a mattress protector?

1. Mattress protectors prevent bud bugs, eliminates dust mites and other allergy causing bacteria.

2. They are hypoallergenic and 100% waterproof - repels all liquids including bodily fluids, perspiration, urine and accidental spills. 

3. They are cool, breathable and wicks away moisture.


Look at it this way: a new mattress is an investment. Protect your investment with a mattress protector!

Will I need new pillows with my new mattress?

We recommend replacing your pillows every 1 - 2 years. Over time, pillows lose their supportiveness. They accumulate body oils, fluids and allergy-irritating dust mites. Pillows help keep your head, neck, shoulders and spine properly aligned.
