Best For
- Side sleepers seeking maximum pressure relief with an enveloping feel, as the layered gel-infused memory foam and latex create a deep, body-hugging cradle at the shoulders and hips while the support foams stabilize the sink to prevent bottoming out - achieving perfect 10.0 pressure relief.
- Eco-conscious shoppers seeking sustainable materials in a luxury mattress, as this mattress features the CoolTemp™ Cover powered by REPREVE® (made from recycled plastic bottles), a Recycled Fiber Support Base, natural latex foam, and CertiPUR-US certified foams - sustainability without sacrificing performance.
- Couples who prioritize motion isolation above all else, as the slow-response memory foam absorbs movement before it spreads and the thick foam stack adds extra damping - achieving perfect 10.0 motion isolation, one of the best scores available for disturbance-free sleep.
Considerations
- Stomach sleepers should avoid; the plush feel (3/10) with extremely deep sinkage (3.09 inches) may allow excessive hip sinkage that can strain the lower back. Stomach sleepers need firmer support.
- Cooling (7.3) is good but not exceptional; while the CoolTemp™ cover and gel foams help, the settling temperature of 28.3°C (82.9°F) is warmer than hybrid options. Hot sleepers who run very warm should consider hybrid mattresses with better airflow.
- Spinal support (7.2) is fair; while the responsive latex adds buoyant pushback to prevent hip dip and the plush top is backed by a supportive core, back sleepers may find the deep sinkage challenges proper alignment - back sleepers should consider firmer options.
Feel & Firmness
At 3/10 on the firmness scale (plush, slightly firmer compared to other plush mattresses), the Serta iComfort Eco Latex 13.5" Plush Memory Foam Mattress delivers a luxuriously conforming sleep experience with eco-conscious materials. With 3.09 inches (7.85 cm) of sinkage - extremely deep - you will experience an ultra plush, immersive hug with maximum conforming. The CoolTemp™ Cover powered by REPREVE® provides a cool-touch, sustainable sleep surface made from recycled plastic bottles. The 1-inch Terra Fusion™ Memory Foam provides conforming pressure relief. The 1.5-inch Latex Foam adds natural buoyancy and breathability that prevents feeling stuck. The 1-inch iComfort® Gel Memory Foam provides gel-infused cooling comfort. The 3-inch Comfort Foam adds additional cushioning. The 1-inch Recycled Fiber Support Base provides eco-friendly transition support. The 6-inch Serta® Foam Core (2.2 lb/ft³ density) beneath delivers stable, consistent support.
The responsiveness score of 8.6 reflects moderate bounce with a slower surface response. The memory foam layers create a cushioned, slower feel at the surface, but the 1.5-inch latex layer adds immediate pushback that helps prevent feeling stuck. Most sleepers should find it easy enough to move around, though it won't feel as springy as hybrid mattresses.
Cooling
This mattress earns a 7.3 cooling score, which is good for an all-foam mattress but has limitations compared to hybrid options. The CoolTemp™ Cover powered by REPREVE® provides a cool-touch sensation at the surface. The 1.5-inch Latex Foam is naturally breathable with an open-cell structure that promotes airflow. The iComfort® Gel Memory Foam features gel infusion that helps regulate temperature. In temperature observations, the mattress showed a baseline of 22.0°C (71.6°F), a maximum of 32.3°C (90.1°F), and settled at 28.3°C (82.9°F). This is warmer than hybrid mattresses due to the all-foam construction, but the cooling technologies help mitigate heat retention for most sleepers.
Motion Isolation
Scoring a perfect 10.0 for motion isolation, this all-foam mattress excels at minimizing sleep disturbances. The slow-response memory foam (Terra Fusion™ and iComfort® Gel Memory Foam) helps absorb movement before it spreads. The thicker foam stack (13.5 inches total) adds extra damping for partner movement. The dense Serta® foam core provides a stable foundation that doesn't transfer vibration. Couples will appreciate that getting in and out of bed causes minimal disturbance to the other sleeper - this is one of the best motion isolation scores available.
Edge Support
With a good 8.8 edge support score, this all-foam mattress provides solid perimeter stability for its construction type. The supportive Serta® foam core (2.2 lb/ft³) helps keep support more consistent toward the edges for sleeping closer to the side. Maximum edge sinkage was measured at 6.36 inches (16.15 cm) with good lying support. While all-foam mattresses typically have more edge compression than hybrids, this iComfort Eco model performs well due to its high-density core construction.
Pressure Relief
The Serta iComfort Eco Latex 13.5" Plush Memory Foam Mattress earns a perfect 10.0 pressure relief score. The all-foam build with layered gel-infused memory foam creates a deep, body-hugging cradle at the shoulders and hips. The Terra Fusion™ Memory Foam and iComfort® Gel Memory Foam conform to body contours. The natural latex adds buoyant cushioning. The support foams stabilize the sink to prevent bottoming out. This design delivers exceptional pressure relief ideal for side sleepers who need their shoulders and hips to be cradled while maintaining adequate support.
Off-Gassing
As a luxury all-foam mattress with CertiPUR-US® certified foams and natural latex, this mattress may have a low initial odour upon delivery that typically dissipates within just 1 day based on reported experience - faster than most all-foam mattresses. The natural latex and certified foams help minimize off-gassing potential.
For best results, allow the mattress to air out in a well-ventilated room for several hours after delivery. Washing your sheets before first use can also help ensure a fresh sleeping environment.

Sleep Position & Body Weight Fit
The plush feel (3/10) with extremely deep sinkage makes this mattress ideal for side sleepers who need their shoulders and hips to sink deeply into a conforming surface for exceptional pressure relief. The deep, body-hugging cradle cushions pressure points beautifully while the support foams stabilize the sink to prevent bottoming out. The responsive latex adds buoyant pushback to help prevent hip dip. Back sleepers may find the deep sinkage challenging for proper spinal alignment - the spinal support score of 7.2 reflects this limitation. Stomach sleepers should avoid this mattress - the ultra plush comfort layers may allow excessive hip sinkage that can strain the lower back.

FAQs
Is the Serta iComfort Eco Latex 13.5" Plush Memory Foam good for hot sleepers?
This mattress scores 7.3 for cooling, which is good for an all-foam mattress but has limitations compared to hybrid options. The CoolTemp™ Cover powered by REPREVE® provides a cool-touch sensation. The 1.5-inch Latex Foam is naturally breathable. The iComfort® Gel Memory Foam features gel infusion. However, the settling temperature of 28.3°C (82.9°F) is warmer than hybrid mattresses due to the all-foam construction. Hot sleepers who run very warm should consider hybrid options with better airflow, though most sleepers will find the cooling adequate.
Does the Serta iComfort Eco Latex 13.5" Plush Memory Foam feel like you sink in or stay on top?
You will experience significant sinking with a deep, body-hugging, enveloping feel. With 3.09 inches (7.85 cm) of sinkage - extremely deep - this mattress creates an ultra plush, immersive hug with maximum conforming. The layered memory foam and latex create a cloud-like sensation. This is ideal for side sleepers who want to be cradled in plush comfort, but may feel too soft for those who prefer sleeping more on top of the mattress.
Is it a good choice for couples?
This mattress is excellent for couples, earning a 9.2 Couples/Intimacy score. It achieves a perfect 10.0 motion isolation score - the slow-response memory foam absorbs movement before it spreads and the thick foam stack adds extra damping. Edge support (8.8) is good for an all-foam mattress. Bounce (8.7) is decent from the latex layer. This combination of exceptional motion isolation with adequate bounce makes it ideal for couples who prioritize disturbance-free sleep.
What sleep positions is it best for?
The Serta iComfort Eco Latex 13.5" Plush Memory Foam is ideal for side sleepers seeking maximum pressure relief - the deep, body-hugging cradle cushions shoulders and hips beautifully. Back sleepers under 150 lb may find adequate support, though the spinal support score (7.2) indicates the deep sinkage can challenge proper alignment for heavier back sleepers. Stomach sleepers should avoid this mattress as the ultra plush feel may allow excessive hip sinkage.
How long does off-gassing usually last?
Based on owner feedback and the construction (CertiPUR-US® certified foams, natural latex), any initial odour is typically low and dissipates within just 1 day - faster than most all-foam mattresses. The natural latex and certified foams help minimize off-gassing. Allow the mattress to air out in a well-ventilated room after delivery.
What makes this mattress "Eco" and sustainable?
The Serta iComfort Eco Latex collection features multiple eco-conscious and sustainable materials:
CoolTemp™ Cover powered by REPREVE®:
• REPREVE® is a performance fibre made from recycled plastic bottles
• Each mattress diverts plastic waste from landfills and oceans
• Provides cooling performance while being environmentally responsible

The iComfort Eco collection proves you can have luxury comfort with eco-conscious materials - achieving perfect 10.0 scores in pressure relief, motion isolation, and off-gassing while using sustainable materials.
What is Terra Fusion™ Memory Foam?
Terra Fusion™ Memory Foam is Serta's proprietary comfort technology:
How Terra Fusion™ works:
• Combines memory foam conforming with responsive support
• Creates a conforming feel that adapts to body contours
• Works with the latex layer to prevent feeling "stuck"
Benefits:
• Exceptional pressure relief at shoulders and hips
• Conforms to body shape without excessive sinking
• Maintains consistent comfort over time
Combined with the 1.5-inch natural latex layer (which adds buoyancy and breathability) and the iComfort® Gel Memory Foam (which adds cooling), this creates a multi-layer comfort system that achieves perfect 10.0 pressure relief while maintaining adequate responsiveness.
