Our verdict
Serta iComfortPro Level Three is part of Serta's current latex hybrid foam lineup. Serta lists the queen at $3,599 (list $4,199). Our score reflects a published specifications and research evaluation of the current model — construction, materials, published firmness, price-per-size and how it stacks up against the rest of the Serta range — rather than a completed lab protocol on this exact unit.

Sleep Position Analysis
Side Sleepers
At 5.5/10 firmness, the Serta iComfortPro Level Three may be worth trying for side sleepers who prefer a medium surface. Body shape, shoulder width and individual preferences can change how the same mattress feels.
Back Sleepers
The Serta iComfortPro Level Three's listed firmness of 5.5/10 may suit back sleepers seeking a medium-to-firm surface. Spinal alignment and hip support have not been objectively measured for this model unless documented test results appear above.
Stomach Sleepers
At 5.5/10 firmness, the Serta iComfortPro Level Three may be too soft for stomach sleepers. Stomach sleepers may want to compare a firmer model, especially if they notice uncomfortable hip sinkage.
Combination Sleepers
The Serta iComfortPro Level Three's latex construction is naturally springy, so it returns to shape quickly when you switch positions — easier for combination sleepers than memory foam.

Read the full Serta iComfortPro Level Three vs. Saatva Classic comparison →Where the Serta iComfortPro Level Three sits in Serta's lineup
Up to 13 inches of latex — the top of the iComfortPro range. Serta iComfortPro Level Three is built around durable foam foundation.
Serta sells this model at $3,599 for a queen (list $4,199). That places it at the premium end in the current lineup, which runs from the $499 Classic innerspring up to the $3,599 iComfortPro Level Three. If your budget is fixed, the table above is the fastest way to see what a hundred dollars either direction actually buys you inside the same brand.
Construction and what the feel is like
The comfort stack is: Advanced cooling cover — cooling fabric system; Graphite-infused latex foam — extra heat-drawing latex layer unique to level three; Professional-grade latex — up to 13 inches of latex in the comfort stack; 5-zone support layer — zoned alignment support; High-density core — durable foam foundation.
In practice, that build gives a medium surface. Luxury foam buyers sleepers get the most out of it; budget shoppers will want to look one model up or down the range. Serta's zoned support systems all share the same idea — firmer coils or foam under the hips and lumbar, softer at the shoulders — so moving between models in this lineup changes the comfort layers far more than the support feel.
Trial, warranty and how we scored it
Serta.com sells this model with a 120-night trial and a 10-year limited warranty, with free shipping. Buying through a retail partner such as Mattress Firm or Costco changes both the trial terms and the price, so confirm the return window at checkout rather than assuming Serta's direct policy applies.
Our 8.8 score is an editorial score. It is not the output of a completed lab protocol on this individual unit, and we say so on every Serta page rather than implying testing we have not done.

Research Evaluation: This mattress has not completed our physical lab testing protocol, and we publish no Sleep Sage lab measurements for it. Our evaluation is based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.
Construction & Materials Review
We document the mattress's published layer construction, materials, densities and cover fabrics from manufacturer specifications and supporting documentation.
Specification & Certification Verification
We check published specifications, certifications and material claims against the manufacturer's own documentation, and flag anything we cannot confirm.
