Bottom Line
The EGOHOME 8-Inch Green Tea Memory Foam Mattress is the best full-size mattress-in-a-box we’ve found under $150 for buyers who want genuine pressure relief without paying hybrid-mattress prices — backed by nearly 12,000 verified ratings averaging 4.3 stars.
Why We Picked the EGOHOME Full Size Memory Foam Mattress
Mattress-in-a-box shopping is a minefield of near-identical listings, and most compress to their stated height only after days of “off-gassing” complaints. EGOHOME stood out because it clears every one of our research gates: CertiPUR-US and OEKO-TEX certified foam, Amazon’s Choice status, and — most importantly — a review base large enough (11,770 ratings) to actually trust the pattern in the feedback rather than a handful of curated five-star reviews. At $143.23 for a Full, it undercuts most name-brand hybrids by hundreds of dollars while using the same gel-infused memory foam construction.
What Owners Actually Say
The recurring theme across verified purchases is fast, low-odor expansion and genuine pain relief. One reviewer wrote: “It was easy to set up, expanded quickly after opening, and had very little odor… I wake up without the usual aches and stiffness.” Another owner managing arthritis and fibromyalgia reported waking up “in no pain” after the first night. A more measured reviewer who ordered the 12-inch Queen version confirmed accurate expansion timing (11 inches within hours, full 12 inches overnight) with no bad odor, and rated it “a fine mattress at a good price point,” noting realistically that “you won’t find anything truly cooling at this price point” — a fair caveat rather than marketing spin.
One Thing to Check
Firmness feedback is genuinely split. The same reviewer above described the feel as closer to a true “medium” than “medium-firm,” and specifically noted it’s most comfortable for sleepers under roughly 150 lbs — heavier sleepers may want to size up in thickness (10″ or 12″ options are available) rather than the 8″ tested here. If you run hot at night, know that multiple owners confirm it sleeps cooler than typical memory foam, but it’s still foam — it won’t match an innerspring or hybrid for airflow.
Pros
- Fast, low-odor expansion — most owners report sleep-ready within a few hours, fully expanded overnight
- CertiPUR-US and OEKO-TEX certified, fiberglass-free cover
- Strong, consistent pain-relief feedback across hundreds of reviews
- Significantly cheaper than comparable hybrid mattresses
- Multiple thickness options (5″ to 14″) if 8″ isn’t the right fit for your weight/frame
Cons
- Firmness runs closer to “medium” than “medium-firm” as advertised, per several owners
- Best suited to sleepers under ~150 lbs at the 8″ thickness; heavier sleepers should consider a taller option
- Standard memory foam heat retention, even if better than some competitors
FAQ
How long does it take to fully expand? Most verified buyers report it’s usable within 4-6 hours and fully expanded to its stated thickness by the next morning.
Does it have a strong chemical smell out of the box? Multiple independent reviewers specifically noted minimal to no odor, which is a common complaint with cheaper foam mattresses.
Is it good for back pain? Several verified owners, including one managing arthritis, reported reduced pain and better sleep quality after switching.
For Specific Needs
Is this a good mattress for a heavier sleeper? Based on real owner feedback, the 8″ Full is best suited to sleepers under about 150 lbs; EGOHOME sells the same construction in 10″, 12″, and 14″ thicknesses which owners suggest for more support at higher body weights.
Will it work on an adjustable bed frame? The listing doesn’t make specific adjustable-base claims for this model, and we didn’t find verified-purchase confirmation either way — if that’s a requirement, confirm with EGOHOME’s customer service before buying rather than assuming compatibility.
Does it sleep hot? Owners describe it as cooler than typical memory foam thanks to the green tea gel infusion, though it’s still foam — if you’re a consistently hot sleeper, temper expectations versus a true hybrid.

How We Built This Guide
Our process: this is a research-based pick, not a hands-on lab test. We aggregate verified-owner reviews, professional test data where available, and real discussion patterns from communities like Reddit, then flag every estimate as such in the guide above. We do not accept sponsored placements.
