As a mattress topper tester, part of my job involves tracking their prices — and I've found great deal this October Prime Day if you're in the market for an affordable queen-size bed topper. Right now, you can save over 20% on a queen-size 3" Lucid Gel Memory Foam Mattress Topper at Amazon, taking the price from $99.99 to $79.26.

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.

Amazon.com Inc. said Thursday its Prime Big Deal Days was its biggest October shopping event ever, as Prime members took advantage of early holiday deals, pushing sales and number of items sold higher than during previous promotions.
