Support	Superior plushness without sacrificing support. More support where you need it most with the plushness you crave. Zoned Support™ Pro offers 7 zones of targeted support for healthy spinal alignment, softer foam around the shoulders provides more relief to the upper body and multiple ergonomic points under shoulders, hips, waist and lower back. A firmer border provides edge support to help you get in and out bed easily. Premium AirScape™ foam conforms to your body to relieve pressure. This has a plush, velvety soft feel. A second layer of supportive foam has 3 ergonomic zones to help align your spine and provide more relief. A third layer with Zoned Support™ Pro relieves pressure under the shoulders, and provides more support under the waist, lower back, and hips to align your spine. These zones reinforce support from the layers above. Fabric-wrapped springs provide active support and a little lift.	The integrated support frame keeps your mattress from flattening when you sit on the edge, and reinforces the structure. This allows you to sleep right on the edge - maximizing your mattress surface. Targeted Zone Support: Your shoulders and hips need a different level of support, so we've adapted the density of our foam according to these areas of your body. Our foam is softer on the shoulder zone, to reduce the pressure felt from day-to-day activity. The hips and torso zone features firmer foam which provides better alignment for your spine.

Is Casper Nova good for back pain?

The Casper Nova is excellent at promoting healthy spinal alignment for lightweight sleepers in all positions and average-weight sleepers who sleep on their sides or backs. The zoned support foam and pocketed coils provide pressure relief and firmness in the necessary areas, helping to alleviate back pain for these sleepers.
