For retailers, keep an eye on big-box stores like Mattress Firm, Macy's, and Wayfair, as they typically offer significant discounts during Black Friday. Online bed-in-a-box companies also tend to have competitive deals. Don't forget to check out Amazon, as they often have a wide selection of mattresses on sale.

To maximize your savings, consider using price comparison tools and setting up price alerts. Also, look for bundle deals that might include pillows, sheets, or bed frames. Remember to read customer reviews and check return policies, as many companies offer sleep trials.

Lastly, while Black Friday deals can be tempting, don't rush your decision. A mattress is a long-term investment in your health and well-being, so take the time to find the right one for you, even if it means waiting for another sale.
