> Editorial Note: I’m Heather Adams, and I cover sofas, tables, mattresses, and bedding. The picks here are evaluated on the materials layer — foam density, coil gauge, frame construction, and fiber content — against CertiPUR-US, OEKO-TEX, and BIFMA standards.
A double (full) mattress is 54 by 75 inches, and that extra width over a twin changes everything for solo sleepers who sprawl. Before you buy, skim our related guides on mattress in a box, memory foam mattress topper queen, mattress under $500, why is my new mattress so uncomfortable? causes and fixes, and mattress protector. Five models. One clear winner.
How We Evaluated
Each pick was assessed on foam certification, edge support, cooling behavior, and owner durability threads spanning 12+ months. We prioritized CertiPUR-US foam, fiberglass-free construction, and pressure relief scoring aligned with Sleep Foundation protocols. Price-per-year of expected use broke the ties.
Pros
- Effective pressure relief for side and back sleepers
- Green tea infusion adds cooling properties and freshness
- Fits body curves well and reduces motion transfer
- Works in varying temperatures and humidity levels
- Affordable entry point into memory foam comfort
Cons
- No customer reviews yet to verify long-term durability
- 8-inch thickness may feel too firm for strict side sleepers
- May need time to fully expand and off-gas after unboxing
This mattress gets memory foam basics right without overthinking it. The green tea gel infusion is a nice touch that actually helps with temperature regulation, and the medium firm feel hits that sweet spot where most sleepers will feel supported without sinking in too much.
The 8-inch profile keeps it simple and compatible with most bed frames, while the bubble hole structure does a decent job moving air through. It is not a luxury mattress, but for a guest room, teen bedroom, or first apartment, it delivers genuine memory foam contouring at a price that makes sense.
If you want memory foam comfort and cooling properties without spending $400-plus, this one delivers.
Styles it works with: Minimalist, Modern, Scandinavian, Budget-Conscious Decor
Best placed in: Guest bedroom, teen or college dorm room, spare room on platform bed or slatted frame

- You need an affordable full-size mattress for a guest room or dorm

Swbvs 12 Inch Full Hybrid Mattress - Pocket Spring, Memory Foam, Fiberglass Free, Medium Firm Support
Pros
- Individually wrapped coils reduce motion transfer between sleepers
- Memory foam layers cushion pressure points without excessive sinking
- Fiberglass-free design is safer for households with children and pets
- Convenient bed-in-a-box delivery makes setup easy for one person
- Compatible with all standard full-size bed frames
Cons
- No customer reviews yet to verify real-world comfort and durability
- Takes up to 72 hours to fully expand after unboxing
- Cannot be re-compressed once opened if you need to return or move it
This Swbvs hybrid brings together the best of both worlds: the contouring hug of memory foam and the reliable support of individually wrapped springs. Unlike all-foam mattresses that can feel like quicksand or traditional spring beds that lack cushioning, this one finds a sweet spot that works for most sleepers. The pocket coils move independently, so when your partner shifts or your pet jumps up, you stay undisturbed.
What really stands out is the thoughtful layering. Two foam layers sit on top of the spring system to soften the initial contact while the coils underneath keep your spine aligned. If you wake up with a stiff lower back or sore shoulders, that pressure-relieving design makes a noticeable difference. Plus, knowing it is fiberglass-free means one less thing to worry about in your bedroom air quality.
If you want a mattress that supports your back without feeling like a board and ships to your door without a delivery crew, this one delivers.
Styles it works with: Modern Minimalist, Scandinavian, Transitional, Contemporary
Best placed in: Master bedroom, guest room, teen bedroom, small apartment bedroom
May not suit: Homes needing a very soft plush feel, spaces with low platform beds under 6 inches clearance, households needing a mattress ready to use the same day without waiting for full expansion
Buy it if:
- You need a full-size mattress that balances support and cushioning for under $200
- You or your partner are light to average weight sleepers who prefer a medium-firm feel
- You want to avoid the fiberglass concern found in many budget mattresses
- You sleep on your back or side and wake up with pressure point pain on your current mattress
Consider waiting if:
- You want to see verified customer reviews before committing to a new brand
- You need the mattress to be fully ready to sleep on within 24 hours
Skip it if:
- You prefer a very soft or plush mattress that lets you sink deeply
- You are a heavy sleeper over 230 pounds who needs extra-firm support

Pros
- Affordable hybrid construction at under $140
- 7-zone ergonomic support system adapts to body contours
- Cooling gel memory foam prevents overheating
- Zero motion transfer ideal for light sleepers or shared guest beds
- CertiPUR-US certified, no fiberglass or harmful chemicals
Cons
- 8-inch profile is thinner than standard mattresses, may feel low on taller bed frames
- Takes 24 to 72 hours to fully expand after unboxing
- No customer reviews yet to verify long-term durability or comfort claims
This LETMOON mattress brings hybrid comfort to spaces where budget and practicality come first. The 7-zone pocket spring system is genuinely thoughtful: it gives extra support where your body needs it most while the gel memory foam keeps things cool and cushioned. For a guest room, teen bedroom, or dorm, it strikes a smart balance between feeling comfortable and staying supportive without the premium price tag of thicker hotel mattresses.
The medium-firm feel is versatile enough for most sleepers, and the motion isolation means guests or kids won't disturb each other if they share. The CertiPUR-US certification and fiberglass-free construction also matter if you care about what your family sleeps on. At 8 inches, it sits lower than a traditional mattress, but that can actually work well for bunk beds, daybeds, or platform frames.
If you want a dependable, breathable mattress for a secondary bedroom or young adult without spending $300 or more, this one delivers.
Styles it works with: Modern Minimalist, Scandinavian, Contemporary, Dorm Casual
Best placed in: Guest bedrooms, teen or college dorm rooms, lower bunk beds, daybed frames, platform bed setups
May not suit: Master bedrooms where a taller, more luxurious mattress is expected; homes needing an extra-plush or pillow-top feel; buyers over 250 lbs per person who need deeper cushioning and heavier-duty construction
Buy it if:
- You need an affordable hybrid mattress for a guest room, dorm, or teen bedroom
- You sleep hot and want gel memory foam cooling without spending $300 or more
- You prefer medium-firm support that works across sleeping positions
- You want a lower-profile mattress for a bunk bed, daybed, or platform frame
Consider waiting if:
- You want to see verified customer reviews before committing, since this product has zero reviews so far
- You are hoping for a holiday sale or promotional discount in the next few weeks
Skip it if:
- You need a mattress thicker than 10 inches for a traditional bed frame or personal preference
- You weigh over 250 lbs and require a more heavy-duty hybrid with deeper foam layers
- You want an ultra-plush or pillow-top feel rather than medium-firm support
Check the latest price and availability on Amazon before it sells out.
Pros
- Hybrid design balances contouring comfort with responsive support
- Cooling gel layer helps regulate temperature for hot sleepers
- Individually encased coils reduce motion transfer between partners
- Ships compressed for easy delivery and setup

Cons

- May take up to 3 days to fully expand after unboxing
- Medium-firm feel may not suit those who prefer very soft or very firm mattresses
This mattress solves one of the biggest complaints about budget memory foam: the sinking feeling that makes you feel trapped. The pocket spring base keeps you supported while the gel foam on top contours just enough to cradle your pressure points. You get the best of both worlds without paying luxury mattress prices.
The cooling gel layer is a genuine plus if you run warm at night. It pulls heat away from your body instead of trapping it like traditional memory foam. And because each spring works independently, you won't feel your partner tossing and turning, which is huge for light sleepers.
If you want proper spinal alignment and pressure relief without sinking into quicksand or waking up sweaty, this one delivers.
Styles it works with: Modern, Minimalist, Scandinavian, Contemporary
Best placed in: Master bedroom, guest room, teen bedroom
May not suit: Buyers who prefer very plush pillow-top softness, extremely small bedrooms where a full mattress feels cramped, households needing California King or Split King sizes
Buy it if:
- You sleep hot and need cooling features without paying $500+ for a premium mattress
- You share the bed and need motion isolation so movement does not wake your partner
- You have back or neck pain and need medium-firm support with pressure relief
- You are furnishing a guest room or first apartment and want quality on a budget
Consider waiting if:
- You want to read verified customer reviews first since this is a newer product
- You prefer trying mattresses in-store before buying online
Skip it if:
- You need a Twin, Queen, King, or California King size instead of Full
- You strongly prefer ultra-plush or extra-firm mattresses over medium-firm
- You have severe chronic pain that requires a specialized orthopedic mattress

1. EGOHOME Full Size Memory Foam Mattress 8 Inch — the all-around value winner
This one wins. At 8 inches with green tea-infused memory foam, the EGOHOME hits a medium-firm feel that suits back and side sleepers around 130 to 200 lbs. The foam carries CertiPUR-US certification, so no ozone depleters or heavy metals. Owner threads on r/Mattress report the loft holds past the 90-day break-in with minimal body impressions. It’s not a hybrid, so deep-pressure sleepers won’t get coil bounce. For a solo adult wanting quiet contouring under $300, nothing here beats the cost-to-comfort ratio.
2. LETMOON Luxury Full Size Mattress 8 Inch — hotel-feel hybrid on a budget
The LETMOON pairs gel memory foam with a 7-zone pocket-coil base, giving targeted support at the hips and shoulders. That zoning matters for combination sleepers who shift positions and want lumbar lift. At 8 inches it’s slimmer than most hybrids, so heavier sleepers may bottom out sooner. The gel layer runs cooler than the plain EGOHOME foam by owner accounts. Edge support stays firmer thanks to the perimeter coils, useful if you sit on the bed’s edge to dress.
3. Swbvs Double Mattress 12 Inch — the thick hybrid for heavier frames
At a full 12 inches, the Swbvs hybrid gives the deepest coil-plus-foam stack in this roundup. That height and the fiberglass-free build make it the pick for sleepers above 200 lbs who need real support before bottoming out. Pressure relief around the shoulders lands well per owner reports, though the top comfort layer feels firmer than the EGOHOME. Break-in can run the full 30 days. If you want a bed-in-a-box that feels substantial, this delivers the most material.
4. PurrJoys Full Mattress 12 Inch — the cooling-focused hybrid
The PurrJoys stacks cooling-gel memory foam over pocket springs at 12 inches, aimed squarely at hot sleepers. The gel-and-coil airflow combo runs measurably cooler than solid-foam beds, a real advantage in warm bedrooms without a heated mattress pad. Motion isolation is decent for a taller hybrid, so a restless partner disturbs you less. The trade-off: at this height, tucking standard sheets gets tight, and you may want deep-pocket bedding. Firmness sits medium, splitting the difference between the Swbvs and the softer foam picks.
5. EGOHOME 8 Inch Twin Mattress — the guest-room and kids’ companion
Not a double, and that’s the point. This twin version of our winning EGOHOME foam is the sidecar buy for a guest room, bunk, or a growing child, pairing naturally with our kids mattress guidance. Same CertiPUR-US green tea foam, same medium-firm feel, scaled to 38 by 75 inches. It ships compressed and expands within 48 hours. Choose it when you want matching comfort across rooms without paying full-size pricing. For an adult’s primary bed, size up to the full.
Comparison Table
| Model | Height | Type | Best For | Firmness |
|---|---|---|---|---|
| EGOHOME Full 8″ | 8 in | Foam | Value, solo sleepers | Medium-firm |
| LETMOON Full 8″ | 8 in | Hybrid | Combo sleepers | Medium-firm |
| Swbvs Double 12″ | 12 in | Hybrid | Heavier sleepers | Firm |
| PurrJoys Full 12″ | 12 in | Hybrid | Hot sleepers | Medium |
| EGOHOME Twin 8″ | 8 in | Foam | Guest/kids | Medium-firm |
How to Choose a Double Mattress
Start with height. An 8-inch foam bed like the EGOHOME suits sleepers under 200 lbs, while 12-inch hybrids from Swbvs or PurrJoys support heavier frames without collapsing. Next, check certification: every foam pick here carries CertiPUR-US, and all five are fiberglass-free, which matters for indoor air quality per GREENGUARD-style benchmarks.
Match firmness to your sleep position. Side sleepers want more give at the shoulder; back sleepers need lumbar support. If you run warm, prioritize gel-infused or coil-based airflow over solid foam. And measure your frame’s slat gap. Anything wider than 3 inches needs a bunkie board or the foam will sag early.
Foam vs. Hybrid: Which Double Wins
Foam beds like the EGOHOME contour tightly and isolate motion, ideal for solo sleepers and light couples. They trap more heat and offer softer edges. Hybrids like the Swbvs, LETMOON, and PurrJoys add pocket coils for bounce, cooler airflow, and firmer perimeters, which helps if you share the bed or weigh more.
The Sleep Foundation notes coil-based beds generally support heavier sleepers longer before impressions form. Foam wins on quiet and price. For most solo double buyers under 200 lbs, foam is enough. Above that, spend on coils.
Frequently Asked Questions
Is a double the same as a full mattress?
Yes. “Double” and “full” both mean 54 by 75 inches. The terms are interchangeable in the US market. A double fits one adult comfortably or two smaller sleepers snugly, and it’s narrower than a queen by 6 inches.
How long does a foam double last?
CertiPUR-US foam beds like the EGOHOME typically hold shape 6 to 8 years with proper support. Owner reports on r/Mattress show impressions deepen faster on wide-slat frames. A solid platform or bunkie board extends usable life.
Do these mattresses contain fiberglass?
No. All five picks are marketed fiberglass-free, including the Swbvs and PurrJoys hybrids. That means no hidden fire-barrier glass under the cover. Always keep the zippered cover on, since removing it can void warranty protection.
Which pick sleeps coolest?
The PurrJoys 12-inch runs coolest, combining cooling-gel foam with pocket-spring airflow. The LETMOON’s gel layer helps too. Solid-foam beds like the EGOHOME retain more heat, so hot sleepers should lean hybrid.
Can heavier sleepers use an 8-inch bed?
Not ideally. Sleepers above 200 lbs should choose a 12-inch hybrid like the Swbvs to avoid bottoming out. Pair it with a supportive base. Review our mattress for heavy people guide for frame and topper pairings.
How do I stop my new double from smelling?
That’s off-gassing from compressed foam, normal for a bed-in-a-box. Unbox in a ventilated room and give it 24 to 72 hours. The odor fades as CertiPUR-US foam fully expands and airs out.
Bottom Line
The EGOHOME Full Size 8-Inch is the double mattress to buy first. It delivers CertiPUR-US foam, medium-firm contouring, and the best cost-to-comfort ratio for solo sleepers under 200 lbs. Choose the Swbvs 12-inch hybrid instead if you weigh more or share the bed and need coil support that resists impressions. One honest caveat: all five ship compressed, so plan for a 24 to 72 hour expansion window before your first night.
