Best For
- Discerning sleepers who want the absolute best performance available and are willing to invest in ultra-premium professional-grade latex construction.
- Side sleepers and combination sleepers who need exceptional pressure relief with the responsiveness to change positions easily throughout the night.
- Couples seeking a plush mattress with perfect motion isolation, outstanding edge support, and responsive bounce that makes the full sleeping surface usable.
Considerations
- The $5,999 Queen price point is a significant investment; sleepers should carefully consider whether the exceptional performance justifies the premium over less expensive alternatives.
- Stomach sleepers and heavier back sleepers may find the plush (3.0/10) feel allows more hip sinkage than ideal; the iComfort Pro Firm option is better suited for these sleep positions.
- While latex typically produces minimal odour, there may be a mild, natural earthy scent initially that dissipates within a few days.
Feel & Firmness
The Serta iComfort Pro Plush Latex rates at 3.0/10 on the firmness scale, which is slightly firmer than typical plush mattresses but still provides deep, enveloping comfort. When you lie down, you will experience a "plush hug" sensation as the True Response™ latex conforms around your body. The sinkage depth of approximately 2.7 inches (6.8 cm) creates an enveloping, wrapped feeling that cradles you while still providing responsive support.
What distinguishes this mattress from memory foam is its exceptional responsiveness, scoring a perfect 10.0. The professional-grade True Response™ latex provides immediate pushback the moment you move, making repositioning completely effortless even with plush sinkage. The 5-zone support construction adds targeted firmness under the lumbar region while allowing shoulders and hips to sink appropriately, maintaining spinal alignment throughout the night. The quilted latex pillow top adds an extra layer of luxurious cushioning at the surface.
Cooling
With a Cooling score of 9.5, the Serta iComfort Pro Plush Latex delivers outstanding temperature regulation for a plush mattress. The CoolFeel™ Pro fabric cover with Serta® Anti-microbial Fibre Technology provides immediate surface cooling and hygienic protection. The graphite-infused True Response™ latex in the top layer actively conducts heat away from your body, while the breathable latex construction throughout promotes continuous airflow. Temperature testing showed a baseline of 22.0°C (71.6°F), a peak of 32.1°C (89.8°F), and a settled temperature of 28.1°C (82.6°F), which is excellent for a plush mattress.
Motion Isolation
Scoring a perfect 10.0 for motion isolation, the iComfort Pro Plush Latex excels at absorbing partner movement. The latex layers dampen motion before it can transfer across the mattress surface, while the dense foam layers add additional vibration control. Testing showed acceleration of 3.09 m/s² with motion duration of 0.93 seconds, meaning disturbances are effectively absorbed. If your partner tosses and turns or has a different sleep schedule, you should experience minimal disruption on your side of the bed.
Edge Support
The edge support score of 10.0 is exceptional for an all-foam mattress. The 6-inch True Response™ Latex Foam Core with a density of 4.8 lb/ft³ provides outstanding stability throughout the mattress, including near the edges. Testing showed good lying support with maximum edge sinkage of 5.66 inches. You can confidently sleep near the edge of the mattress without roll-off concerns, and sitting on the edge (such as when getting dressed) produces less compression than typical foam mattresses. This makes the iComfort Pro an excellent choice for couples who want to use the full sleeping surface.
Pressure Relief
With a perfect 10.0 for pressure relief, the Serta iComfort Pro Plush Latex excels at cushioning sensitive areas. The quilted latex pillow top with Serta® Pillo-Fill and PillowSoft foam provides luxurious initial softness, while the graphite-infused True Response™ latex creates responsive contouring at shoulders and hips. The 5-zone support system adds targeted cushioning at pressure points while maintaining firmer support under the lumbar region. This makes it exceptionally well-suited for side sleepers and anyone with chronic pain or pressure sensitivity.
Off-Gassing
The Serta iComfort Pro Plush Latex earned a 10.0 for off-gassing performance, with a low initial smell strength and an expected off-gassing period of approximately 3 days. Latex naturally produces less odour than memory foam, and the graphite infusion can help absorb any initial scent. The CertiPUR-US certification confirms the foams are made without harmful chemicals and meet strict emissions standards.
To minimize any initial scent: (1) allow the mattress to air out in a well-ventilated room for a few hours before making the bed, and (2) the natural latex smell, if present, is typically mild and earthy rather than chemical. Most owners report any scent dissipates within a few days under normal conditions.

Sleep Position & Body Weight Fit
The plush feel and responsive latex construction of the Serta iComfort Pro Plush Latex make it exceptionally well-suited for side sleepers who need maximum cushioning at the shoulders and hips. The 5-zone support system helps maintain spinal alignment by providing targeted lift under the midsection. The responsive latex also makes it excellent for combination sleepers who change positions throughout the night. Lighter back sleepers (under 150 lb) typically find good support with the plush top backed by the zoned support system. Stomach sleepers and heavier individuals generally require firmer surfaces.
