As a sleep writer, I know from testing mattress toppers that they can soften and cool even the firmest and warmest of beds — and there are plenty on sale this October Prime Day. My favorite deal is one where you can save up to 50% on the Tempur-Pedic TEMPUR-Adapt + Cooling at Amazon, with a queen now down from $499 to just $251. In comparison, there's no deal on this topper at Tempur-Pedic's official website.  

Tempur-Pedic appears in our best mattress of 2024 guide for all sleepers, while the Tempur-Adapt Topper ranks No 1 in our guide to this year's best mattress toppers. However, you can find plenty of great bed topper deals away from today's Amazon Prime Day deals, with Brooklyn Bedding, Birch, and Casper offering Prime Day-beating deals of their own. 

So, whether you're looking for a budget gel-infused memory foam topper for affordable and refreshing softness, or a a mattress topper deal with premium cooling features and better benefits, here's my three Amazon Prime Day mattress deals. Plus, I've also cherry picked three rival discounts, from Casper, Birch Living and Brooklyn Bedding.

However, this deal includes a cooling upgrade thanks to a temperature-controlling cover. Right now, a queen is 50% off at $251 (that's right, it's cheaper than a twin, which is only 36%) down from $499.

1. Casper Comfy Topper: was from $199 now from $149.25 at Casper

1. Casper Comfy Topper: was from $199 now from $149.25 at Casper
Our Casper Comfy Mattress Topper review found this topper to be perfect for side sleepers in need of pressure relief - and it offers a surprising amount of cooling, too. Usually, you'll only find a 10% discount on the Comfy Topper at Casper, but they've now rolled out a 25% sale, taking a queen from $199 to $149.25. This is a much better deal than the one you'll find on Amazon, plus you'll also get the perks of buying directly from the brand such as a 30-night sleep trial and 5-year warranty.
