Bear, the maker of our favorite side sleeper mattress, is also running a sale during Prime Day. It's got 35 percent off sitewide with the code PRIME, plus two free pillows with any mattress purchase. It brings the mattress to the price we usually see it available for, though the $150 worth of pillows makes it a bit of a discount.

The bed-in-a-box memory foam mattress is made of five layers that include a heat-wicking quilted cover with cooling technology, perfect for hot sleepers who often deal with night sweats. Once delivered to your door, it's super easy to set up, too. Just take it out of the box, lie it on top of your frame, and let it expand for 24 hours.

From now until end of day October 10th, Saatva mattresses are $300 off when you shop through our exclusive links. P.S. Each mattress comes with free white-glove delivery and setup at no extra cost. Saatva’s delivery team will also remove your old mattress for free if you select the mattress removal option at checkout.
