I test mattresses for a living: These are the only 9 Prime Day deals worth buying today — starting from $162 for a queen

The Saatva Classic scored an unprecedented 5 stars in our review, hitting all the right notes for comfort and support for practically every type of sleeper. Our semi-exclusive sale access unlocks $400 off all sizes of the Classic in the current Saatva mattress sale, taking a queen down to $1,829 from $2,229 . While that is an excellent deal, we have tracked a small MSRP increase on the classic, which, until a few days ago, was priced at $2,139. Still $400 is the best deal you'll get on the best hybrid mattress we've tested.

If you're looking for a decent mattress for your guest bed or dorm room that won't break the bank, this is it. The Zinus has dropped to just $162 for a queen(was $233.99), which is now the lowest price we've seen this year. Our testers like the Zinus most for side sleeping, as it gently cradles along the shoulders, hips and knees. It's important to note that shopping this deal direct from Amazon means you'll forgo the 100-night trial but the 10-year warranty still stands.

The DreamCloud Classic is an exceptionally well-price mattress, even at its usual sale price of $699 for a queen. However, there's a further 15% off over at DreamCloud right now, which takes a queen down to $552. That undercuts the $649 Prime Day deal at Amazon today, offering unbeatable value for money. DreamCloud mattress sales are usually pretty static, but this is one we'd recommend jumping on before it's gone.

The Bear Elite Hybrid is a great choice for chronic hot sleepers, thanks to its actively cooling PCM-laced cover and breathable build. It comes in three firmness options for all sleepers but co-sleepers should note that its bouncy surface causes noticeable motion transfer and support around the edge is average (at best). That aside, using the code TOMS40 unlocks an exclusive 40% off saving, taking a queen down to $1370.40, which matches the lowest price we've tracked.

The Casper Element is an Amazon exclusive from the hugely popular mattress in a box brand. Right now, a queen is $474 down from $645, which is the lowest price we've tracked in the past 12 months. With an average customer score of 4.3 from 6,000 reviews, customers rate it highly for its balanced support for side sleepers, as well as lumbar support for back pain relief.

The Classic is among the best memory foam mattresses we've tested, thanks to its supportive comfort vs cost. However, while Nectar mattress sales tend to hold steady throughout the year, they've just launched a rival Prime Day sale, which takes a queen Classic down to the ultra low $552 from the usual sale price of $699. That's the lowest price we've tracked in the last 12 months. Plus, it comes with a 365-night trial and lifetime warranty.

You'll pay $294 for a queen in Siena's 'Prime Time' rival sale, which is an excellent price (albeit, not the lowest we've ever seen). However, while Amazon was historically the place to buy a Siena at the lowest price, the Signature is now only sold direct from Siena. So, if you want the best cheap mattress we've tested, that's where you'll need to buy it.

One of the cheapest hybrid deigns you'll find, the Linenspa 8" Hybrid is perfect for dorm rooms, guest beds, and growing kids and teens. Linenspa is currently running a Prime Day-rovalling sale where a 15% discount is automatically added to your cart. This deal takes a twin XL from $159.99 to $136. A queen size and full is currently sold out, so you'll need to act fast to grab a twin and twin XL mattress for under $150 (plus a 10-year warranty and 30-day returns).

The SweetNight CoolNest Mattress is one of the most budget-friendly cooling mattress on the market today, and thanks to Prime Day, it just got cheaper. A 14" model in a queen is $399.49 at Amazon. Meanwhile, the same model and size is $469.99 at the SweetNight website, and the MSRP is $629.99. While the 10-year warranty offered by SweetNight still applies, buying the CoolNest from Amazon may mean you miss out on the brand's 100-night sleep trial.

The Tempur-Adapt + Cooling 3" Mattress Topper is our top choice in our best mattress toppers guide as it provides both cooling tech and the luxury pressure relief of a Tempur-Pedic mattress for less. Right now, there's up to 38% off at Amazon, taking a queen-size down $309 (was $499) after months of a discount drought.

The Lucid Gel Memory Foam Mattress Topper is one of our top budget picks, and it's ideal for side sleepers and anyone wanting to soften hard beds. All sizes of the 3" model are on sale for Prime Day at Amazon, but be aware that the dorm-sized twin XL is currently sold out. However, the popular queen size is now $84.99 (was $99.99).

Amazon is full of cheap mattress toppers, but the problem is that not many of them provide the luxurious thickness and padding needed to transform a bed's firmness. However, this dual-layered pillow top mattress topper has a 4" build that's perfect for giving mattresses a budget cooling makeover. A queen size is now $115.99 down from $149.99 at Amazon.
