Save up to $300 on these three budget mattresses with these extended Amazon Prime Day deals — but you'll have to act fast, these deals due to end any time now.

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.

These are the best Prime Day bedding deals to shop during Amazon's massive savings event. Shop editor-tested sheets, pillows, comforters, and more.

While a lot of mattress topers are made from memory foam or down and feather, latex mattress toppers are becoming increasingly popular thanks to their sustainability, durability, breathability, and responsive feel. They are also hypoallergenic, protecting you against allergens such as dust mites.
