🛏️ King Koil Natural Retreat Glacial Mist Pillow Top Medium Mattress Feel & Firmness
The King Koil Natural Retreat Glacial Mist Pillow Top has a medium feel (≈ 5.5–6/10):
- Surface Feel: Plush and cushioned due to the pillow top

🛌 Sleeping Position Performance
| Sleep Position | Performance |
|---|---|
| Back Sleepers | ⭐⭐⭐⭐☆ (Very Good) |
| Side Sleepers | ⭐⭐⭐⭐☆ (Very Good) |
| Stomach Sleepers | ⭐⭐⭐☆☆ (Good) |
| Combination Sleepers | ⭐⭐⭐⭐☆ (Very Good) |
Why it works:
The plush pillow top cradles pressure points while the zoned coils help maintain spinal alignment. Side sleepers appreciate the cushion at shoulders and hips, and back sleepers enjoy balanced support. Stomach sleepers may experience slight sink, but overall the medium feel still covers a broad range.
🌡️ Cooling Performance
The Natural Retreat Glacial Mist Pillow Top focuses on airflow and heat management:
- Breathable cover & pillow top materials
- Innerspring construction promotes airflow through coils
- Heat-wicking quilting fibers in the top layers
🔥 Cooling Rating: ⭐⭐⭐⭐☆ (Very Good)
This mattress tends to sleep cooler than most foam beds due to its innerspring core and breathable pillow top, making it a solid choice for warmer climates or hot sleepers.
🛋️ Motion Isolation & Edge Support
Motion Isolation

- The pillow top + coils absorbs some motion, but not as quiet as foam
- Couples may notice partner movement overnight
Edge Support
- Reinforced edges provide stable support when sitting or sleeping near the perimeter
- Feels solid compared to typical foam encased innersprings
