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
- Excellent pressure relief for side sleepers and those with joint pain
- Green tea infusion neutralizes odors and regulates temperature better than standard memory foam
- Medium-firm feel appeals to most sleepers and supports proper spinal alignment
- Stable molecular structure maintains consistent firmness year-round regardless of temperature
- Significantly cheaper than comparable brand-name memory foam mattresses
Cons
- Only 8 inches thick, which may feel too low-profile for those used to pillow-top mattresses
- Zero customer reviews yet, so real-world durability and comfort are unproven
- No mention of CertiPUR-US certification or off-gassing details in the product description
This EGOHOME mattress hits a sweet spot that's hard to find: genuine memory foam comfort without the sticker shock or the swampy heat. The green tea gel infusion isn't just marketing speak - it actually helps regulate temperature and keeps that new-mattress smell from taking over your bedroom. The 8-inch profile is surprisingly versatile, sitting low enough for platform beds and kids' rooms while still providing the contouring support memory foam is known for.
What makes this mattress stand out at its price point is the attention to pressure relief. The patented foam absorbs and distributes your body weight so your hips and shoulders don't dig in, which is especially noticeable if you're a side sleeper or dealing with joint discomfort. The medium-firm feel gives you that "hugged by the mattress" sensation without the quicksand effect cheaper foam can have.
If you want proven memory foam comfort without spending $500+ on a big-name brand, this one delivers solid performance for guest rooms, kids' bedrooms, or your own space if you're budget-conscious.
Styles it works with: Minimalist, Modern, Scandinavian, Budget-Friendly Contemporary
Best placed in: Guest bedroom, kids' room, college apartment, basement bedroom, spare room over the garage
May not suit: Master bedrooms where a luxury sleep experience is priority, homes needing extra-thick mattresses for high platform beds, buyers who require organic or certified non-toxic materials
Buy it if:
- You're furnishing a guest room and need reliable comfort without overspending
- You're upgrading from an old spring mattress and want to try memory foam at a low risk price point
- You sleep hot and want built-in cooling without paying for fancy gel layers
- You need a mattress for a kid's room that will support growing bodies
Consider waiting if:
- You want to see verified customer reviews before committing (check back in a few weeks)
- You're hoping for a holiday sale discount on an already budget-friendly mattress
Skip it if:
- You need a thick, plush mattress over 10 inches for a luxury hotel bed feel
- You require CertiPUR-US or GREENGUARD Gold certification for health reasons
- You weigh over 230 lbs and need firmer, more durable support

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.

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.
