Cyber Monday (like Black Friday) is a great time to snap up one of this year's best mattresses for less. Some of today's best Cyber Monday mattress deals offer you the chance to buy a luxury bed at a more budget-friendly price, while some cheaper entry-level models —  such as the Allswell X 10” being reduced to $70 in Walmart’s holiday sale — hit rock bottom prices.

But with so many last-minute sales flying around, how can you tell which deals are actually with the money? Luckily, I’ve been on the lookout for the greatest bed sales, so I’ve rounded up all the best-value mattresses that are worth checking out this Cyber Monday.

I’ve also included info on extras such as trials and warranties, and which kind of sleepers each mattress is actually designed for — and which sleepers should avoid. Let's take a closer look...

1. DreamCloud Hybrid Mattress: $839DreamCloudTrial period:Warranty:Best for:

1. DreamCloud Hybrid Mattress: from $839 $449 at DreamCloud
Trial period: 365-night sleep trial
Warranty: Lifetime warranty
Best for: back sleepers and couples

This firm, luxury hybrid is perfect for all sleepers thanks to its four layers of comforting foam. Our testers for the DreamCloud Mattress review praised its layer of individually wrapped coils for motion isolation and recommended it for bed-sharing couples. Its hybrid design also gives it a luxurious feel without the heat-trapping tendencies of all-foam beds. Right now, you can get 40% off this DreamCloud mattress, reducing a queen to $799 and a king to under $1000, which is amazing value for a luxury hybrid.  It also comes with generous extras such as a 365-night trial, lifetime warranty, free shipping and returns,  and an offer on a bedding bundle. However, sleepers with a lighter build may find it too firm, which is why we also recommend the memory foam version (a king is now $949).

Individually wrapped coils also provide great motion isolation for couples and cooling airflow for hot sleepers.

We rate the Helix Midnight as the best mattress for side sleepers thanks to its cushioning memory foam that soothes the pressure points of shoulders and hips. Its contouring medium feel also supports restless sleepers, while its top cover with Helix’s trademark cooling technology will leave hot sleepers feeling cool and comfortable. Couples are in good hands, too, thanks to this fiberglass-free hybrid’s strong motion isolation.

Within this entry-level Memory Foam Mattress, Siena delivers incredible value. In our Siena Memory Foam review, testers found the motion absorption makes the the mattress ideal for bed-sharing couples, plus the fantastic edge support means it's easy to get in and out of bed. Despite being a memory foam, it’s quite firm and doesn’t have that classic ‘hug’ of a foam bed – but it does deliver good temperature regulation for a cooler sleep. Stomach and heavyweight sleepers should suit this bed well, even if back and side sleepers may take some time to adjust to its firmness. Right now, you can get $500 off a Siena Memory Foam, saving you over 50% on a queen reduced to $399 (was $799).

With its plush comfort, firm support, and medium feel, Serta’s Perfect Sleeper suits all sleep styles – making it perfect for couples and guest bedrooms.

Its also made with a soft fiber layer with hypoallergenic, antimicrobial properties to protect the mattress from mold, mildew and bacteria. Despite its cooling gel foam and breathable materials, the cooling technology is pretty average, so hot sleepers may want to opt for a mattress with more temperature-regulating properties. Right now, this Serta mattress is 45% off for a queen, going from $ $1099.99 down to $599.99. Plus you can get an adjustable base (worth up to $499.99) free when you use the code ELEVATE.

9. Beautyrest PressureSmart™ 2.0 Firm 11" Mattress: from $599.99 $999.99 at Mattress Firm
Trial period:120 night sleep trial
Warranty: 10-year limited warranty
Best for: back and stomach sleepers

If you sleep on your back or stomach or have a heavier-than-average build, Beautyrest’s PressureSmart 2.0 is firm enough to alleviate lower back pain by keeping your spine supported and aligned. It’s great for hot sleepers,too, thanks to its temperature-regulating technology that draws away heat and keeps the surface cool. Couples should also enjoy its motion isolation, which means you won’t be able to feel your partner’s tossing and turning. However, this is a super-firm bed, and it’s likely that lightweight and side sleepers won’t get the cushioning comfort that’s right for them. Right now, Mattress Firm’s Cyber Monday Deal has knocked 30% off the PressureSmart, but you can boost that discount to 40% off with the code SCORE100. Using the code ELEVATE scores you a free adjustable base (worth up to $499.99). This is an epic deal, and with extras such as a 120-night sleep trial, 10-year warranty, and free delivery, now is definitely the right time to buy a firm Beautyrest mattress for less.

The Birch Natural is one of this year's best organic mattresses thanks to its fiberglass-free hybrid design, eco-friendly materials such as latex and organic wool, and responsive surface. In our Birch Natural mattress review, we found that the bed was cool enough for hot sleepers and bouncy enough for front and back sleepers. Our testers did note, however, that it can be too firm for side and light sleepers, and couples and restless sleepers may want something with more motion isolation. The mattress is often on sale at 20% off, but has increased to 25% off this Cyber Monday with a queen size down to $1,592 (was $2,123).
