Fresh, cool, and supportive — the Sierra is designed to make great sleep easy. With a 12” hybrid profile, Sierra blends the refreshing comfort of swirled CoolGel memory foam with the reliable support of individually wrapped coils, creating a balanced feel that works for a wide variety of sleepers.
Right beneath the breathable grey waterfall cover, a thick layer of CoolGel memory foam cushions your body and relieves pressure while drawing away excess heat for a cooler, more refreshing night’s rest. A transition layer of high-density comfort foam smooths the shift into the pocketed coil support system, which adapts to your body, isolates motion, and provides edge-to-edge stability so you can stretch out comfortably.
The result is a mattress that feels airy, supportive, and effortless — bringing you cooling comfort and dependable support at a price that makes better sleep more accessible than ever.
- 12” Hybrid Design – Balanced comfort + support
- Pro Gel™ Memory Foam – Cooling pressure relief with a fresh, buoyant feel
- Pocketed Coil System – Durable stability + reduced motion transfer
- Breathable Waterfall Cover – Soft, modern, and built for airflow
- Everyday Value – Premium comfort without the premium price
