Both share the same premium construction, but the Medium includes a different comfort foam layer for a softer, more adaptive feel. The Firm is best for those who want extra support, while the Medium is better for sleepers who like more cushion.

A medium feel mattress strikes the perfect balance between the softness of a plush mattress and the rigidity of a firm one. It offers enough cushioning to relieve pressure points on your hips and shoulders (ideal for side sleepers) while maintaining sufficient support to keep your spine properly aligned (great for back and stomach sleepers). The NXT 2000 Medium is an excellent choice for couples with different sleep preferences and is our most recommended comfort level for the majority of sleepers.

Copper is a natural element with several benefits for sleep. First, it's highly conductive, meaning it helps pull excess heat away from your body for a cooler, more comfortable night. Second, copper has natural antimicrobial and hypoallergenic properties, which helps create a cleaner sleep environment by resisting the growth of bacteria, mold, and dust mites.

A 5-zoned coil system means the pocketed coils are strategically arranged to provide varying levels of support across five distinct zones of the mattress. Firmer coils are placed in the center third of the mattress to support the heavier lumbar area, while softer coils are used for the shoulders and legs. This targeted support promotes healthier spinal alignment, reduces tossing and turning, and helps alleviate back pain.
