NXG Memory Foam Technology

The high-density NXG Memory Foam provides deep contouring that conforms to body shape for pressure relief at shoulders and hips. This innovative premium foam responds to body weight and temperature, cradling pressure points while maintaining supportive foundation for proper spinal alignment.

5-Zone Coil System

The 5-zone hybrid coil system features alternating firm and plush areas that target different body regions. Firmer coils beneath lumbar region provide back support while softer coils cushion shoulders and hips. BestEdge Support maintains stability from edge to edge, maximizing sleeping surface and preventing roll-off.

The CoolFeel Cover provides cool-to-touch surface that delivers immediate cooling sensation when you lie down, helping you fall asleep faster. The fabric dissipates body heat for comfortable initial contact with mattress surface.

The Carbon Fiber Memory Foam layer actively draws heat away from body throughout the night. Carbon fiber's thermal conductivity pulls warmth from sleep surface and disperses it, maintaining comfortable temperature. This dual cooling approach combines immediate surface cooling with sustained heat dissipation for all-night comfort.

Use mattress protector to guard against stains. Rotate head-to-foot every three to six months for even wear. Avoid jumping or standing on mattress. Do not fold or bend. Allow new mattress to air out for 24-48 hours after unboxing.

What is NXG Memory Foam?

NXG is high-density premium memory foam engineered for deep contouring and pressure relief. More dense than standard memory foam, it provides enhanced durability and responsive support while conforming to body curves. The advanced formulation balances pressure relief with proper spinal support.

Why is this good for side sleepers?

The plush feel provides cushioning for shoulders and hips where side sleepers experience most pressure. NXG Memory Foam contours to these pressure points while 5-zone coils maintain spinal alignment. The combination prevents pressure buildup and keeps spine neutral during side sleeping.

What is hybrid vs all-foam?

Hybrid combines memory foam comfort with coil support. The foam layers provide pressure relief and contouring while coils offer responsive support, breathability, and edge stability. Hybrid mattresses typically sleep cooler and provide bouncier feel compared to all-foam mattresses.

How does carbon fiber cool?

Carbon fiber conducts heat efficiently, drawing warmth away from body and dispersing it throughout mattress. This thermal conductivity prevents heat buildup that occurs with standard memory foam. Combined with CoolFeel Cover, it creates dual cooling system for comfortable sleep temperature.
