Casper Cloud One King Mattress with Head Up Only Base

A standard king mattress set like this one is ideal for couples who prefer a continuous, seamless sleep surface without a "gap" in the middle. While the split king variation offers individualized movement for each side, this standard king set allows the entire mattress to move in unison. Measuring 76 inches wide, it provides ample personal space for two adults while maintaining the intimacy of a shared bed.

One of the most common concerns with foam mattresses is heat retention. To address this, Casper has integrated breathable layers into this mattress's design specifically to combat overheating. These layers facilitate better airflow than traditional high-density foams, helping to regulate your body temperature and ensure you wake up refreshed, even in humid coastal or southern environments.

A "tight top" indicates that the mattress has a flat, uniform surface without the extra "pillow" layer sewn onto the top. This design is preferred for those who want to feel the immediate support and responsiveness of the underlying specialty foam layers. It provides a stable, consistent sleep surface that works in harmony with the adjustable base, ensuring the mattress bends easily without the bunching or shifting sometimes found in thicker-topped models.

The Casper Cloud One is constructed with an advanced layer of specialty foam pillars designed to provide a "cloud-like" feel without sacrificing structural integrity. These pillars, combined with thicker layers of premium comfort foam, are strategically engineered to cradle the body’s natural contours. This provides targeted pressure relief and added support to the hips, waist, and lower back, which is essential for maintaining proper spinal alignment throughout the night.

This adjustable set features the RTG Sleep 2900 base, specifically engineered for lifestyle flexibility. By using the included wireless remote, you can elevate the head of the mattress to find the perfect ergonomic angle for reading, working on a laptop, or watching television. Beyond leisure, elevating the head can also be a proactive solution for those looking to manage common sleep issues like snoring or mild acid reflux by keeping the airways more open and the torso supported.

The adjustable base included in this set features a sleek, 4-inch low-profile design and black legs. Because it is a "head-up only" powered base, it is designed to be highly compatible with most modern bed frames that accommodate a king-size mattress. Its low height ensures that even when paired with the 11-inch mattress, the overall bed height remains accessible and fits the aesthetic of contemporary master suites.
