Serta Five Star Tranquility 10-Inch Medium Queen Mattress - Balanced

In this review of the Serta Five Star Tranquility 10-Inch Medium Queen mattress, the bottom line is simple: it is best for sleepers who want a balanced, medium-firm surface that combines targeted lumbar support with breathable foam for cooler nights. The mattress stands out because its 3-zone lumbar band and combination of PillowSoft Aire and PillowSoft foams deliver noticeable pressure relief around the shoulders, hips, and knees while keeping spine alignment steady for combination sleepers. Setup is quick thanks to the mattress-in-a-box design and the included 100 night trial and 10-year limited warranty add confidence to the purchase.

Key Features

• Medium-firm comfort: A balanced feel supports proper alignment without feeling too soft or overly firm, which suits combination sleepers.
• Zoned lumbar support foam: The 3-zone support layer targets the lower back and hips to reduce pressure and help maintain neutral spine alignment.
• Cushioned pressure relief: PillowSoft Aire and PillowSoft Foams contour around shoulders, hips, and knees to relieve common pressure points.
• Breathable cooling design: Airflow-enhancing cover fabric and breathable foams promote a cooler sleep surface than dense, heat-trapping foams.
• Durable support: Supportive coils are engineered to limit partner disturbance and provide lasting foundational support across the mattress.
• Easy setup and certification: The mattress ships compressed in a box for fast unboxing, and all foams are CertiPUR-US certified.

Who It's For

The Tranquility 10-Inch Medium is a good fit for combination sleepers and couples who need a middle-ground feel that balances contouring and support. Those who value lumbar support and pressure relief without sinking too deeply will appreciate the gel-infused lumbar band and layered PillowSoft foams.

Shoppers who sleep exclusively on their side and prefer very plush, cloudlike cushioning or those who need an ultra-firm surface for heavy-body types should look elsewhere, since this model is tuned to medium-firm comfort rather than extreme softness or maximum firmness.

Pros & Cons

Pros

• Targeted 3-zone lumbar support reduces lower-back pressure for better alignment.

Cons

• Some customers reported mixed feedback on exact size and thickness fit, so double-check bed frame clearance and dimensions before ordering.
• Medium-firm feel may not satisfy those who need very soft or extremely firm surfaces.
