Sometimes in order to help with mattress sales a company such as a national retail store or national brand of mattress will have a charity event. They advertise that if you buy a mattress during this special event a portion of the sale will go towards a certain charity.
Many times people will think “hey I need a mattress, why not help a great charity at the same time”?
Before you pay full retail for mattress to help a charity organization or event, stop and realize that you will be paying 4 or 10 times more for the same mattress that you could purchase at another store. It is probably better to donate directly to the charity and shop around for your new mattress and compare. After all, you will be spending 1/3 of every day laying on that mattress long after the charity event is over.
Purchasing a new mattress should not be combined with other things such as charities to distract you from making a logical and educated decision.
