The pre-holiday season savings event is officially kicking off on October 8 and ending on October 9, but mattresses are already as low as $218 (with over 1,000 five-star reviews ), and price cuts are as high as 51 percent off top brands like Casper, Nectar, and Purple. (Seriously, this Casper mattress is over $1,000 off right now.)

The Prime Big Deal Days event is on October 8 and 9, but we're already seeing mattress deals from Purple and Nectar, with up to 51 percent off.

A good mattress can be a pricey investment, so keeping it safe from accidents is always a good idea. Right now on Amazon Canada, the Cozymaker Queen Size Mattress Protector is currently 25 per cent off ahead of Prime Big Deal Days. Shoppers say the waterproof protector saves mattresses from spills and accidents while also being "very comfortable."
