Frequently Asked Questions

What is your return policy?

Mattress King sells the highest quality mattresses at wholesale prices.
Comfort is every thing! 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 takes time for your feet to adjust to the shoe's soles; it also takes time for your body to adjust to a new mattress.


The 30-Day Comfort Exchange* - If the customer is not completely satisfied with their mattress they can exchange it for a different mattress in our store. 


The mattress must be equal or greater value. If the customer chooses a mattress of greater value, they will be charged the difference between the first mattress and the second one, plus tax and delivery. 

​Customers are allowed one Comfort Exchange per transaction, and it must occur within the first 30 days of delivery. 

All sales are final. There are NO refunds. The 30-Day Comfort Exchange does NOT apply to warranty items or floor model-demos.

*Mattresses with stains, markings, or strong odors of any kind do not qualify for the 30-Day Comfort Exchange. Mattresses delivered outside the state of California do not qualify for the 30-Day Comfort Exchange. 

How long is the warranty on my mattress?

Every mattress sold at Mattress King comes with a minimum 10 year manufacture's warranty.

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 35% 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!

*Customer who do not purchase a mattress protector from Mattress King forfeit the 30 Day Comfort Exchange!

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.
