A good night’s sleep can change everything—from focus at work to mood at home. The EGOHOME King Size Memory Foam Mattress stands out in a crowded market by offering a thick 14-inch profile, cooling gel foam, and solid support at a price far below many big-name brands.
King-size memory foam mattresses often climb past $1,500, yet this model typically sells for hundreds less on Amazon US. You spend about one-third of your life in bed.
According to the CDC, adults need at least 7 hours of sleep per night for optimal health. A mattress that supports your spine and relieves pressure plays a major role in that equation.
So how does this one perform in real-world use? Here’s what you should know before adding it to your cart.
EGOHOME King Size Memory Foam Mattress Overview and Key Features
The EGOHOME King Size Memory Foam Mattress comes in 10-inch, 12-inch, and 14-inch options, with the 14-inch version being the most popular for those who want deeper cushioning. The king size measures 76″ x 80″, giving couples generous space to stretch out.
On Amazon US, the 14-inch king model generally ranges from $599 to $799, depending on seasonal discounts. That pricing places it firmly in the affordable luxury category.
Key product details:
- Gel-infused memory foam comfort layers
- High-density support base foam
- Breathable knit cover
- CertiPUR-US® certified foam
- Bed-in-a-box delivery
- 100-night sleep trial (retailer dependent)
- 10-year limited warranty
This mattress is designed to balance pressure relief with structural support, targeting common complaints like lower back tension and overheating.
Construction Breakdown: What You’re Actually Sleeping On
When shopping for the best king size memory foam mattress, materials matter more than marketing.
This mattress uses multiple foam layers:
Top Layer: Gel-infused memory foam
Designed to contour around shoulders, hips, and lower back. The gel helps disperse body heat instead of trapping it.
Transitional Layer: Responsive foam
Adds structure and prevents that deep sinking sensation some people dislike.
Base Layer: High-density support foam
Keeps the mattress stable and helps maintain spinal alignment over time.
The foam is CertiPUR-US® certified, meaning it’s tested for low VOC emissions and made without certain harmful chemicals. That certification is common among reputable brands and provides peace of mind.
From hands-on testing, the 14-inch model feels substantial and supportive right out of the box. Expansion took about 36 hours in a ventilated room, with only mild off-gassing that faded quickly.
Firmness Level and Support: Who Is It Good For?
This mattress falls in the medium-firm to firm range. On a 1–10 firmness scale, it feels around a 6.5 to 7 during the first week.
If you’re looking for a firm memory foam mattress for back pain, this design may work well. The foam contours without collapsing under the hips, which helps maintain spinal alignment.
From direct testing:
- Back sleepers get consistent lumbar support
- Side sleepers feel pressure relief at the shoulders and hips
- Stomach sleepers benefit from the firmer base layer
Heavier individuals (over 275 lbs) may experience more compression, which is common with all-foam mattresses. In that case, a hybrid model could offer stronger edge and core reinforcement.
Cooling Performance: Does the Gel Foam Actually Help?
Traditional memory foam tends to retain heat. That’s one reason many shoppers search for a cooling gel memory foam mattress.
The EGOHOME model incorporates gel-infused foam designed to regulate temperature. In testing, the surface felt neutral rather than warm. It didn’t create a cool-to-the-touch sensation like some high-end specialty fabrics, yet it avoided the heat buildup common in older foam designs.
For hot sleepers:
- Use breathable cotton or bamboo sheets
- Add a lightweight cooling mattress protector
- Ensure airflow around the bed frame
According to the Sleep Foundation, cooler sleep environments help improve sleep quality. While this mattress won’t replace air conditioning, it performs better than many entry-level foam beds.
Motion Isolation and Edge Support
If you share a bed, motion isolation matters. Memory foam generally absorbs movement better than innerspring mattresses.
In practical testing:
- Movement on one side transferred very little to the other
- Partner position changes caused minimal disruption
- Getting in and out of bed stayed relatively quiet
Edge support is decent but not exceptional. Sitting on the edge causes some compression, which is typical for an all-foam king size mattress. If you frequently sit on the edge to get dressed, you may notice some sink.
Couples who need maximum edge stability might prefer a hybrid mattress with reinforced coils.
Delivery, Setup, and First Impressions
The mattress arrives compressed in a box. For a king size, the packaging is surprisingly manageable.
Setup process:
- Move the box to your bedroom.
- Unroll the mattress onto your foundation.
- Carefully remove plastic wrapping.
- Allow 24–72 hours for full expansion.
Initial firmness feels slightly stronger than expected. After about two weeks, the foam relaxes into its intended feel. There was mild new-foam odor during unboxing. Good ventilation reduced it significantly within a day.
Comparing It to Other King Size Memory Foam Mattresses
When you compare this to other king size memory foam mattress reviews, the biggest difference is price-to-thickness ratio.
Many 14-inch king memory foam mattresses from well-known brands cost $1,200–$1,800. Those often include advanced cooling fabrics or brand recognition, yet the support layers are similar in density.
Pros:
- Affordable for a 14-inch king
- Strong motion isolation
- Good pressure relief
- CertiPUR-US® certification
Limitations:
- Edge support could be stronger
- No coil reinforcement
- Cooling is moderate, not extreme
Some buyers prefer hybrid mattresses for bounce and airflow. Others prefer the body-hug feel of foam. It comes down to sleep style and preference.
Durability and Long-Term Performance
Foam density plays a key role in durability. Higher-density base foam resists sagging longer.
After extended use, the mattress maintained structure with minimal body impressions. Rotating the mattress every 3–6 months helps extend lifespan.
Industry-wide, memory foam mattresses typically last 7–10 years depending on quality and usage. The included 10-year limited warranty aligns with that expectation.
For extra longevity:
- Use a mattress protector
- Avoid placing it directly on the floor long-term
- Ensure proper support from a platform or slatted base
Who Should Consider This Mattress?
This mattress fits best if you:
- Want a 14 inch memory foam mattress king size without premium-brand pricing
- Prefer medium-firm support
- Sleep on your back or side
- Share a bed and need motion isolation
- Want a king mattress in a box for easy delivery
If you prefer extra bounce or reinforced edges, a hybrid may suit you better. If you like deep contouring and minimal motion transfer, this mattress checks those boxes.
Real-World Perspective from Testing and Research
Years of reviewing sleep products show one pattern: comfort is personal. No mattress works for everyone.
During evaluation, this model delivered consistent lumbar support and reduced shoulder pressure for side sleeping. It performed comparably to higher-priced foam competitors in the same thickness category.
Sleep health research supports investing in proper support. The National Institutes of Health links chronic sleep disruption to long-term health risks. While a mattress won’t fix every issue, supportive alignment plays a role in sleep quality.
Some users report it feels firm at first. That adjustment period is normal for dense foam. Giving it a few weeks helps your body adapt.
Final Thoughts on the EGOHOME King Size Memory Foam Mattress
The EGOHOME King Size Memory Foam Mattress offers substantial thickness, reliable support, and cooling features at a reasonable Amazon price. It performs well for back and side sleepers and minimizes motion transfer for couples.
It’s not the most advanced cooling mattress on the market, and edge support could be stronger. Still, for the cost, it delivers solid value in the king size memory foam category.
If you’re looking for supportive comfort without spending four figures, this option deserves a closer look. You can explore current pricing and customer reviews on Amazon and compare it with other models that fit your sleep style.
