Sierra Sleep Millennium Hybrid Mattress

A tight top provides a smooth, uniform surface without the extra layer of padding found on a pillow top. While it still offers a plush, luxurious feel, it tends to be more supportive and less prone to body impressions over time.

The mattress is designed to minimize motion transfer. By combining a NanoCoil unit with individually wrapped coils, the mattress isolates movement to the specific area where pressure is applied, so you are less likely to be disturbed by a partner shifting positions.

Copper is highly conductive, which allows it to draw excess body heat away from the surface of the mattress. Combined with phase change material, this helps maintain a consistent, cooler sleep temperature throughout the night.

Yes, this hybrid mattress is fully compatible with adjustable bed bases. Its flexible construction allows it to bend and contour to the base's movements without compromising the integrity of the coils.

While the mattress will be usable shortly after unboxing, it typically requires 24 to 48 hours to fully expand and reach its intended firmness and shape. We recommend waiting this period before placing heavy bedding on it for optimal performance.

The green tea infusion is primarily included to help keep the base foam fresh and odor-free over time. It provides a subtle, natural way to maintain a cleaner sleep environment.
