Cheap Mattress deals online — Where to find them

Holidays are — not surprisingly — the best time of year for mattress sales. November, in particular, is a great month as we expect to see the lowest prices of the year as retailers debut their November mattress deals. However, if you need a cheap mattress deal now — many Labor Day discounts have been extended through the end of the month, which is why we're still seeing such strong mattress sales. 

Mattress deals — tips to remember

  • Never pay full price: Labor Day, Black Friday/Cyber Monday, Memorial Day, and July 4th are generally the best time of the year for mattress deals. (If we had to pick one holiday — Black Friday/Cyber Monday would be the one we recommend). However, even if you're nowhere near a major holidays, most mattress companies offer mattress deals year-round. So you should never pay full price for any mattress. 
  • Know your return policy: Buying a new mattress — especially these days — can be tricky. Perhaps you're relying on user reviews or word of mouth. Or maybe you've already tried the mattress and have finally found the right mattress deal. Either way, you should always know the mattress' return policy should you have to return it. Some companies offer 100-night trials with free return shipping and no penalty fees , whereas others offer 18-months trials with similar shipping policies.
