The Zinus Green Tea Memory Foam 12 inch King tops our list for the mattress deals during Prime Big Deal Days, thanks to its layered foam build, CertiPUR-US certified foams, and more than 91k owner reviews backing it up. Side sleepers get the pressure relief they want, and the bed has stayed a long-running favorite for budget-conscious shoppers. Runners-up worth watching are the Ashley Chime 12 Inch Queen Memory Foam for a balanced medium-firm feel that suits couples, and the Novilla Bliss 12 Inch Gel Memory Foam Queen for shoppers who run warm at night. Prime Big Deal Days runs October 6-7, 2026, and these are the mattresses our team would shortlist first.
Mattress shopping during Amazon’s October sale is one of those rare moments when a big-ticket home upgrade actually drops in price. The catch: hundreds of listings appear at once, the deals move, and the same bed can show up under three different model codes.

How We Chose
Owner ratings, review counts, materials and certifications do the heavy lifting here. We pulled the listing details and reviewer themes for every mattress in this roundup and checked the data again in October 2026. The aim is simple: surface the beds that owners actually stick with, by sleep position and by budget, so the picks worth watching during Prime Big Deal Days are easy to tell apart.
1. Zinus Green Tea Memory Foam 12 inch King: Editor’s Choice
Zinus Memory Foam 12 Inch Green Tea Mattress, King, White
Size: King
Firmness: Medium firm
Type: Memory foam
Height: 12 inch
Warranty: 10 year
Pros
- Layered memory foam for pressure relief
- CertiPUR-US certified foam
- Green tea and ActivCharcoal infusion
- Fiberglass free construction
- Strong owner track record across 91k reviews
Cons
- Some reviewers find it firmer than expected
- Edge support weaker than a hybrid
- Initial off-gassing reported by a few buyers
This is the bed we keep coming back to when side sleepers ask for a King. The build pairs 3 inches of conforming memory foam with a 2-inch airflow comfort layer and a 7-inch high-density base, so you get the hug at the shoulders without losing support under the hips. Owners with back pain often flag it in reviews as the first mattress that actually let them sleep through the night.
The 91k+ reviewer base is what separates this Zinus from the rest of the field. Most of the competition is new or smaller, but this one has years of owner feedback behind it, which is why it remains the safest King-size shortlist pick in the roundup.
For pure memory foam shoppers, this Zinus is the cleanest pick on the list. Combination sleepers who want bouncier support should look at the Novilla 14 Inch Hybrid Queen (#6), which adds pocketed coils under the foam for a more responsive feel.
The green tea and ActivCharcoal infusion is more than marketing. Several reviews mention the bed stays fresher between sheet changes, which matters in a smaller bedroom with limited airflow or in a guest room that sits empty for weeks at a stretch.
2. Ashley Chime 12 Inch Queen Memory Foam: Best Value
Signature Design by Ashley 12 Inch Memory Foam Queen Mattress in a Box
Size: Queen
Firmness: Medium firm
Type: Memory foam
Height: 12 inch
Warranty: 10 year
Pros
- Balanced medium firm feel
- CertiPUR-US certified foam
- Low motion transfer for couples
- Removable washable cover
- Compatible with most frames and adjustable bases
Cons
- Some reviewers find it firmer than expected
- Edge support could be stronger
- Initial off-gassing reported by some
The Chime 12 Inch Queen is the model we point couples toward when they ask for a comfortable all-rounder without paying premium prices. The medium firm feel keeps the spine aligned for back sleepers and gives side sleepers enough give at the shoulder, while low motion transfer keeps partner tossing from becoming partner wakeups.
Owners report it as one of the easier bed-in-a-box unboxings for a Queen setup, with the box opening cleanly and the foam rising to full 12 inch height within a day. Several reviews mention moving from a worn spring mattress to this one and noticing quieter nights almost immediately.
If you want gel cooling for a hot bedroom, the Novilla Bliss 12 Inch Gel Memory Foam Queen further down is the natural alternative. For shoppers who sleep at a steady room temperature and want a calmer, more traditional foam feel, the Chime is the smarter shortlist pick.
For households that occasionally host kids or pets, the removable washable cover is a real practical win. Spills and dust wipe off without rotating the entire mattress, which keeps the bed fresher over the long term.
3. Novilla Bliss 12 Inch Gel Memory Foam Queen: Most Compact
Novilla Bliss Queen Size Mattress, 12 Inch Gel Memory Foam Mattress Queen
Size: Queen
Firmness: Medium firm
Type: Gel memory foam
Height: 12 inch
Trial: 100 nights
Pros
- NanoGel memory foam for cooling
- CertiPUR-US certified foam
- ACA endorsed for back health
- Reinforced edge support
- Strong motion isolation for couples
Cons
- Some reviewers report warmer sleep than expected
- Can feel firmer to lightweight sleepers
- Full expansion can take up to 72 hours
The Bliss is the gel memory foam pick that earns its premium tag. Novilla layers NanoGel memory foam with comfort foam and a dense base, and the build is endorsed by the American Chiropractic Association for back health. For shoppers who wake up hot or whose partner runs warm, the gel infusion is the difference between a mattress you tolerate and one you actually enjoy.
The 100-night trial gives hot sleepers a real runway to test whether the gel layer actually performs in their bedroom. Owners in warmer climates report the bed staying close to room temperature through the night, which is the kind of detail that does not show up in spec sheets.
Couples who sleep cool and want Queen dimensions will be happiest on this Novilla. The trade-off against the Zinus Cooling Gel 12 inch King (#4) is size for trial: the Bliss is the Queen with a 100-night window, while the Zinus is the larger King without the extended trial.
One practical note for setup: the foam can take the full 72 hours to expand in cooler rooms, so leave it in a warm, ventilated space before sleeping on it. Owners who rushed it into the bedroom overnight sometimes reported a lingering new-foam smell that disappeared once the bed had a day to breathe.
4. Zinus Cooling Gel Memory Foam 12 inch King: Best for Hot Sleepers
ZINUS 12 Inch Green Tea Cooling Gel Memory Foam Mattress / Cooling Gel Foam / Pressure Relieving / CertiPUR-US Certified / Bed-in-a-Box, King
Size: King
Firmness: Medium
Type: Gel memory foam
Height: 12 inch
Warranty: 10 year
Pros
- Cooling gel and green tea infusion
- Multi-layer foam construction
- CertiPUR-US certified
- Pressure relieving design
- Lightweight at 78 pounds
Cons
- Some reviewers report initial odor
- Firmer than expected for lightweight sleepers
- Less contour than classic memory foam
If your King bedroom runs hot, this Zinus swaps the classic memory foam top for a 2-inch ultra-cooling gel and green tea infused layer. The result is a King-size bed that sleeps noticeably cooler than its non-gel sibling at the top of this list, with the same CertiPUR-US certified foam construction underneath.
The build also reads more supportive than the classic Zinus Green Tea 12 inch King, which keeps heavier sleepers from sinking through the comfort layer. Owners in warm climates say the green tea infusion keeps the surface noticeably less musty than a basic foam bed, which is a small but real comfort on humid nights.
Strict side sleepers under 140 pounds should look at the Zinus Green Tea 12 inch King (#1), which is the softer pick in this roundup, and combination sleepers who want bounce will find it in the Novilla 14 Inch Hybrid Queen (#6). This Zinus Cooling Gel is best for hot sleepers in the 140 pound and up range.
At 78 pounds this King is on the lighter side for the category, so one person can unbox it and set it on the frame without help. Keep it in a ventilated room for the first day so any new-foam smell clears quickly.
5. MLILY EGOHOME 14 Inch Queen Memory Foam: Best for Back Pain
EGOHOME Queen 14 inch Memory Foam Mattress for Back Pain Relief Medium Firm
Size: Queen
Firmness: Medium firm
Type: Copper gel foam
Height: 14 inch
Warranty: 10 year
Pros
- ICA endorsed for back health
- Copper gel infusion for cooling
- Multi-layer foam construction
- CertiPUR-US certified
- Graphene cool tech cover
Cons
- Costs more than basic memory foam
- Weight capacity capped at 250 lbs
- Some reviewers report initial odor
This 14-inch Queen is the bed we point chronic back pain sufferers toward. MLILY layers copper gel aerofuion memory foam over Adaptifoam and a high-density base, and the International Chiropractors Association endorsement is rare at this price. The graphene-cool cover pulls heat away from the surface, which keeps the deep foam layers doing their job through the night.
Owners with chronic shoulder and hip pain are the loudest voices in the review base, and several mention dropping pain medication after switching to this mattress. The taller 14-inch profile gives the foam layers room to do their pressure-relief work without bottoming out.
The 250-pound weight cap is the obvious limit. Sleepers above that threshold should look at the Novilla 14 Inch Hybrid Queen (#6), whose pocketed coil base handles heavier bodies. For everyone under the cap who has chronic pain and wants a foam bed, this MLILY is the cleanest shortlist pick.
Deep-pocket sheets are not optional at 14 inches. Most reviewers end up buying a new sheet set alongside the mattress, and several note that the extra depth turns the bed into something close to a hotel-mattress feel, which is part of the appeal for primary bedrooms.
6. Novilla 14 Inch Hybrid Queen: Best Hybrid
Novilla 14 Inch Queen Size Mattress, Hypoallergenic & Back Pain Relief, Hybrid Queen Mattresses in a Box with Smarts Coils, Fiberglass Free CertiPUR-US Certified Colchones No Box Spring Needed
Size: Queen
Firmness: Medium plush
Type: Hybrid
Height: 14 inch
Cover: OEKO-TEX
Pros
- SmartS pocketed coil system
- AirBreeze fabric for cooling
- CertiPUR-US certified foam
- Fiberglass free construction
- Strong edge support
Cons
- Pillow top can wrinkle on arrival
- Medium plush feel softer than classic memory foam
- Smaller review base than other picks
The hybrid shoppers in our notes usually want one thing: bounce plus contour. Novilla answers with pocketed SmartS coils under foam comfort layers and an AirBreeze cover that moves heat away from the body. It is also fiberglass free, which matters to a lot of buyers who do not want a fire retardant layer they cannot see.
This is the only hybrid in the roundup. Every other mattress here is pure foam, so combination sleepers who switch between side, back, and stomach through the week will not find this exact build elsewhere on the list.
For pure-foam shoppers who want a firmer, classic memory foam feel, the Novilla Bliss 12 Inch Gel Queen (#3) is the natural alternative in the roundup. The Hybrid sits at medium plush, the Bliss at medium firm, so the choice is mostly about whether you want bounce or contour at the shoulders.
The Euro top can show light wrinkles when first unpacked, but owners report they flatten within a week. Deep-pocket sheets are required for the 14-inch profile, and the OEKO-TEX cover keeps the surface breathable for warm bedrooms.
7. Zinus 6 Inch Green Tea Full: Best for Guest Rooms
Zinus 6 Inch Full Green Tea Memory Foam Mattress, Medium Firm Feel
Size: Full
Firmness: Medium firm
Type: Memory foam
Height: 6 inch
Warranty: 10 year
Pros
- Budget friendly entry point
- Green tea and ActivCharcoal infusion
- CertiPUR-US and OEKO-TEX certified
- Lightweight at 27.7 pounds
- Good for bunk beds and trundles
Cons
- Thinner profile may not suit all preferences
- Some reviewers find it firmer than expected
- Limited cushioning for heavier sleepers
A guest-room mattress lives a strange life: used a few weekends a month, sometimes a week at a time, and ignored the rest. The Zinus 6 Inch Full is built for exactly that. At 27.7 pounds it is light enough to swap between rooms, and the CertiPUR-US and OEKO-TEX certifications reassure guests who ask questions.
Think of it as a weekend bed: bunk rooms, trundles, the spare bedroom that only sees family during the holidays. The thinner 6-inch profile works on frames with limited clearance, including low-platform styles where a deeper mattress would lift sleepers above the headboard.
The 6-inch profile is the obvious limit for a primary bedroom. Daily sleepers over 180 pounds should step up to the EGOHOME 8 Inch Green Tea Full (#9), which gives the foam more depth for full-night use and runs cooler with its green tea gel layer.
The cotton cover is breathable, which helps in guest rooms that are closed up between visits. Adding a mattress protector is a smart move for households with kids visiting, and the low weight makes the whole setup easy for one person to refresh between guests.
8. FDW 8 Inch Gel Memory Foam Twin: Best for Kids
FDW | 8 Inch Twin Mattress | Medium Firm | Gel Memory Foam | White
Size: Twin
Firmness: Medium
Type: Gel memory foam
Height: 8 inch
Capacity: 1000 lbs
Pros
- Gel infused foam for cooling
- High 1000 lb weight capacity
- CertiPUR-US certified foam
- Removable washable cover
- Lightweight at 28 pounds
Cons
- Some reviewers report initial off-gassing
- Firmer than expected for some
- Edge support could be stronger
A kids’ Twin mattress has to survive spills, jumps, and growth spurts. The FDW 8 Inch uses gel-infused memory foam with a removable, washable cover that parents appreciate, and a 1000-pound weight capacity that outlasts anything a teenager can throw at it. The ventilated gel layer is a quiet win for warm sleepers.
Parents in the reviews mention the washable cover most often: juice spills, nighttime accidents, and dust all come off without rotating the foam. The 1000-pound capacity means the bed still feels supportive when a teenager piles on for a movie, which matters more than the spec suggests.
The Twin sizing is the obvious trade-off. For a guest-room Full at this height, the Zinus 6 Inch Green Tea Full (#7) or the EGOHOME 8 Inch Green Tea Full (#9) is the right alternative. For a kids’ room or first bedroom, this FDW Twin is the most resilient pick on the list.
Standard Twin sheets fit without deep pockets, which keeps the setup simple when the mattress ends up on a bunk or trundle that limits clearance. At 28 pounds the box is light enough for one adult to carry up a staircase.
9. EGOHOME 8 Inch Green Tea Full: Best Mid-Profile
EGOHOME Full Size Memory Foam Mattress 8 Inch, Green Tea, Medium Firm
Size: Full
Firmness: Medium firm
Type: Gel memory foam
Height: 8 inch
Capacity: 750 lbs
Pros
- Patented premium memory foam
- Green tea gel for cooling
- CertiPUR-US certified
- Fiberglass free construction
- 10 year warranty
Cons
- Some reviewers find it firmer than expected
- Initial expansion takes patience
- Can feel warm for some users
The EGOHOME 8 Inch Full is the middle ground between the budget 6-inch guest mattresses and the deeper 12-inch primary bed picks. The 4-layer foam build with green tea gel keeps temperature stable, and the fiberglass free construction is the safety note reviewers tend to mention.
Full-size shoppers who want one bed for everyday sleep without paying the Queen premium will land here. The green tea gel layer reads cooler than a basic memory foam Full at the same height, which is a real plus in warmer climates and south-facing bedrooms.
For households that only need a guest bed used twice a year, the Zinus 6 Inch Green Tea Full (#7) is the lighter, simpler option. For a Full bed that someone sleeps on every night, the EGOHOME 8 Inch is the smarter long-term pick without going up to a Queen.
At 30 pounds the box is light enough for a single adult to position, and the 750-pound weight capacity leaves headroom for two adults sharing a Full. Owners with back pain on the EGOHOME list it as a step up from thinner 6-inch foam beds, particularly for side sleepers.
10. Best Price Mattress 6 Inch Full: Most Versatile
Best Price Mattress Full Mattress 6 inch Bed-In-A-Box, Green Tea Memory Foam White
Size: Full
Firmness: Medium
Type: Memory foam
Height: 6 inch
Warranty: 10 year
Pros
- Strong value for money
- Green tea infusion for freshness
- CertiPUR-US certified foam
- Pressure relieving memory foam
- 10 year warranty included
Cons
- Thin profile may not suit everyone
- Some reviewers report initial odor
- Can feel firm for side sleepers
If the goal is to put a usable Full mattress in a room for the lowest possible outlay, the Best Price Mattress 6 Inch Full is the entry point. CertiPUR-US certified foam, green tea infusion, and a 10-year warranty at the budget tier is a tough combination to beat.
Dorms and first apartments are the use case the specs fit best. The 6-inch profile slips into tight rooms, the green tea infusion keeps the foam fresh in spaces without strong ventilation, and the 10-year warranty outlasts most student leases.
Anyone over 180 pounds who sleeps on this bed nightly should look at the Zinus 6 Inch Green Tea Full (#7) and the EGOHOME 8 Inch Green Tea Full (#9) instead, both of which give the foam more depth for full-night use.
At 30.4 pounds the box is light enough to carry up a flight of stairs by yourself, which matters in older walk-ups without an elevator. A removable mattress protector is the only add-on owners consistently recommend for daily use.
How to Choose a Mattress During Prime Big Deal Days
Prime Big Deal Days brings a flood of mattress listings, and the trick is filtering them down to the ones that fit how you actually sleep. These are the buying factors that matter most when the sale goes live.
Sleep position and firmness match
Side sleepers usually do best on medium to medium firm mattresses with enough give at the shoulder; back sleepers usually want true medium firm for lumbar support; stomach sleepers usually want firmer mattresses that keep the hips from sinking. In this list, the Zinus Green Tea 12 inch King (#1) and the Ashley Chime 12 Inch Queen (#2) are the strongest fits for side sleepers, while the MLILY EGOHOME 14 Inch Queen (#5) is the pick for back pain sufferers. If you wake up with sore hips, layering a mattress topper for hip pain on a firmer base is often the simplest fix.
Mattress type and feel: memory foam, hybrid, latex and innerspring
Memory foam gives contour and low motion transfer, which suits couples and side sleepers. Hybrid beds like the Novilla 14 Inch Hybrid Queen (#6) add pocketed coils for bounce, airflow, and edge support. Latex and traditional innerspring are less common in this sale; pure innerspring is the right pick only if you want the bounciest feel and the coolest surface. For shoppers who run hot, gel-infused memory foam (the Novilla Bliss #3 and the Zinus Cooling Gel #4) usually outperforms classic foam by a noticeable margin.
Size, profile and bedroom fit
Mattress dimensions are standardized: Twin at 75 by 38 inch, Full at 75 by 54 inch, Queen at 80 by 60 inch, King at 76 by 80 inch, California King at 84 by 72 inch. Profile runs from 6 inch (the Zinus 6 Inch Full and Best Price Mattress 6 Inch Full) up to 14 inch (the MLILY EGOHOME 14 Inch Queen and the Novilla 14 Inch Hybrid Queen). Low-profile 6 to 8 inch mattresses fit bunk beds, trundles, and adjustable bases with limited clearance. Twelve to fourteen inch profiles feel more like a hotel bed and need deep-pocket sheets.
Trial period, warranty and return shipping
For a sale-day purchase, the minimum to accept is a 100-night trial and a 10-year warranty. The Novilla Bliss 12 Inch Gel Queen (#3) checks both boxes, as do the Zinus picks with their 10-year limited warranty. Most bed-in-a-box brands in this roundup cover return shipping within the trial window, but verify the policy on the listing before checkout, since the fine print varies.
Cooling features for hot sleepers
Real cooling tech in this list comes from gel-infused memory foam (Novilla Bliss #3, Zinus Cooling Gel #4, FDW #8, EGOHOME #9), pocketed coils with airflow (Novilla Hybrid #6), and breathable covers (OEKO-TEX on the Novilla Hybrid). Marketing words like “cooling cover” without a gel or coil system are usually just breathable fabric. Hot sleepers should focus on gel memory foam or hybrid picks rather than classic foam.
How to shop mattress deals during the sale
When Prime Big Deal Days goes live, start by confirming the model year and firmness variant in the listing title. A “12 inch Green Tea Memory Foam” can hide three different builds. Check the bundle: pillows, bases, and mattress toppers bundled with the mattress are sometimes worth the same as the discount. Look for “renewed” or “open box” tags that are easy to miss. Confirm the seller is Amazon or the brand itself rather than a third party. A mattress protector for bedwetting or general use is a smart add-on to order at the same time.
Mattress Deals: Prime Big Deal Days Checklist
- Pick a firmness: medium firm for back and most side sleepers, firmer for stomach sleepers, softer for lightweight side sleepers.
- Pick a type: memory foam for contour and couples, hybrid for bounce and airflow, gel memory foam for hot sleepers.
- Pick a size: Twin for kids, Full for guest rooms and small bedrooms, Queen for most couples, California King for tall sleepers.
- Verify the trial is at least 100 nights and the warranty at least 10 years.
- Confirm cooling tech (gel, coil, breathable cover) if you sleep warm.
- Check seller, model year, firmness variant, and Prime requirement on the listing before checkout.
Frequently Asked Questions
When do the Mattress Deals: Prime Big Deal Days run in 2026?
Prime Big Deal Days runs October 6-7, 2026. The mattress offers typically go live at midnight Pacific on the first day and continue through the end of the second day, with new deals appearing across both days.
Do I need a Prime membership to get the mattress deals during Prime Big Deal Days?
Yes. Most of the mattress deals during Prime Big Deal Days require an active Amazon Prime membership. A free 30-day Prime trial qualifies, and student trials also count, so you can sign up just before the sale and still access the offers.
How long is a typical mattress trial period for bed-in-a-box brands?
Most bed-in-a-box brands in this roundup offer a 100-night sleep trial, which gives you roughly three months to decide. Some brands go to 365 nights, and a few still sit at the older 30-night minimum. Read the trial terms before checkout since return shipping responsibilities vary.
Are mattresses usually discounted more during Prime Big Deal Days or Black Friday?
Both events usually feature meaningful mattress discounts, but the depth varies by brand and by year. Prime Big Deal Days tends to lean on bed-in-a-box brands like Zinus and Novilla, while Black Friday often pulls in more premium names. Watch both events if your shortlist is flexible.
How long does a bed-in-a-box mattress take to expand and off-gas after delivery?
Most mattresses in this list are usable within 24 hours, though some brands recommend 48 to 72 hours for full expansion. A mild new-foam smell is normal during the first day or two and usually disappears with airflow from a fan or open window.
What should I check on a mattress listing before buying during the sale?
Check the exact model number, firmness variant, size, and bundle contents. Look for seller information, shipping speed, and whether the listing is new, renewed, or open-box. Confirm the trial period and return shipping policy, and verify the deal is actually a Prime member offer rather than a separate third-party promotion.
Final Verdict: Mattress Deals: Prime Big Deal Days
The mattress to watch most during the sale is the Zinus Green Tea Memory Foam 12 inch King, which pairs layered memory foam with CertiPUR-US certified construction and more than 91k owner reviews behind it.
