Sierra Sleep By Ashley Millennium Hybrid Mattress and Foundation

Plush indicates a softer, more cushioned feel that allows you to sink slightly into the mattress. It is designed to provide a cloud-like comfort while still maintaining the underlying support of the hybrid coil system.

Copper is a highly conductive material that helps draw excess body heat away from the surface of the mattress. Combined with the gel-infused latex, it works to dissipate heat throughout the night, preventing the 'trapped heat' feeling common in traditional memory foam.

The combination of individually wrapped coils and the NanoCoil unit is specifically engineered to isolate motion. Because each coil reacts independently to pressure, movement on one side of the bed is significantly less likely to transfer to the other.

Yes, the metal foundation is designed for superior durability and stability compared to traditional wood-frame box springs. It provides a rigid, consistent surface that prevents sagging and helps extend the overall lifespan of your mattress.

The NanoCoil unit acts as a micro-support layer that sits above the main coil system. It provides targeted, responsive pressure relief that contours closely to your body, helping to alleviate aches in sensitive areas like shoulders and hips.

Yes, the plush firmness level and the pressure-relieving memory foam layers make this an excellent choice for side sleepers. The materials are designed to cushion the hips and shoulders while keeping the spine aligned.
