Price history: There’s always some sort of discount on the Casper Element, varying between 10 and 30%. So, the Amazon Prime Day deal is one of the cheapest we’ve seen, with a queen coming down to $416.50 from an MSRP of $595. The mattress only dropped to $446 on Black Friday, so I’d suggest snapping this one up today.

Now through Wednesday, July 17, the Casper sale is offering up to 30% off everything — including mattresses , bedding, bundles, furniture and more. Prime Day is typically one of the best times of year to shop for larger purchases like a new mattress, so don't sleep on these savings.

But above all, my mattress has proven to be the most important element to guarantee a deep and restful night's sleep, and a morning free of aches and pains. Lucky for you, my favorite mattress is deeply on sale for Amazon Prime Day.
