Price History: Saatva only offers a $400 discount on all mattresses over $1,000 during major holiday sales such as the Black Friday deals or Labor Day sales. Last month, the 15% off sale could only get you $400 off the split king size. The only savings available on the other sizes were between $200-$350.

Not convinced yet? This might do it: For Black Friday, with our exclusive link (discount shows at checkout), Saatva is offering 20 percent off all purchases of $1,000 or more through Cyber Monday, which means up to $900 off. That's a pretty big deal.

Yes! In fact, Black Friday through Cyber Monday is the best time of the year to invest in big-ticket purchases like mattresses. These savings events mark the official start of the holiday shopping season, which means that retailers typically offer their steepest discounts during this time.
